Can't tether my laptop to my rogers nexus 4? - Nexus 4 Q&A, Help & Troubleshooting

Hey guys
I have a nexus 4 going through rogers wireless, i have a 6gb data plan as well. I am using the wifi hot spot setting and creating the wifi network for my laptop. My laptop connects no problem and shows full signal, however I can't seem to surf the Web or do anything.
The laptop connects fine to my home network, and the nexus 4 is updated to the latest firmware. It is also stock and not rooted, any help?

Just to add, i do not have LTE, this is a regular data plan and tether

I'm not going to much help myself, sorry. My hotspot worked fine out of the box (I'm with Mobilicity), though I recall that I had to set up a password for it to start working correctly. Have you tried USB tethering for the sake of troubleshooting?

Just tried to tether via usb and no connection either!

I am on Rogers, my WiFi tether works fine, I don;t think it maters what data plan you have, I have a 10GB 3 year old plan. But It has to be ion WAP2 security, if you don;t do the password it won't work.
My USB tether only worked through this app https://play.google.com/store/apps/details?id=com.pdanet&hl=en
You need to have it on the PC as well http://pdanet.co/
Re: WiFi, I know you saying you don;t have LTE, but just to make sure go to dial pad and type in *#*#4636#*#* and make sure towards the bottom WCDMA Proffered is selected. Then check that your APN is not ltemobile.apn in settings.
Also sometimes it helps to do a trouble shoot on the connection in windows, rarely but sometimes it works from second third time.
Try PDAnet, I think it has WiFi tethering as well.

I have it on WAP2
I used the dialer settings and WCDMA preferred is enabled
That app failed to change anything, I can connect no problem just can't surf the Web
And my apn is not the one mentioned
Hmm.....

very strange: so,
What's the set up you have, ROM/KERNEL/RADIO/GAPPS?
For the test of it, if you want, I had this and it worked, you can just back up and flash this set ups:
ROM: Slim or RootBox
Kernel: Harsh
GAPPS: Slim or Banks
Radio: .33 (I have not tested it on .48)
Also if your usb tethering did not work with the PDANet, then probably something wrong in the ROM. USB tether needs drivers so if they are not installed properly will be a probably, but since WifI is not working as well I a pretty sure it's a ROM problem, maybe you just need to to do a clean flash of a similar in features ROM to what you are using now.
If you really like the one you using now, one good idea would be to do a logcat right after it connects and you can;t brows the web, and submit that to the dev thread of the ROM.

Appreciate the assistance
My phone is 100% stock and I don't want to tinker with it, I was hoping it would work as promised out of the box, is it the latest update of jelly bean causing issues?

sometimes the provider blocks tethering until you buy their tether plan. even though some people say it works fine, you could still be one of the few that were blocked. i tethered for four years fine, until one day tmobile blocked it until i bought a tethering plan.

Every time I tether my N4 I have to go the through Windows trouble shooting process, it never connects right the first time.

Rogers said that any plan over 1gb of data is automatically allowed to tether

Try checking your APN settings (do a APN reset). If you have more than one, it may be using the wrong one.

Right Rogers does not block it and its free.
It maybe the new radio, but since you are not rooted, not much you can do.
One thing is try a tethering app in play store it does not need root.
Two, do a factory reset in settings somewhere.
Try changing the APN to ltemobile.apn it may work better.
Last resort is to email Google support maybe they will answer.
But also like previously mentioned do troubleshoot the connection in windows maybe few times.
Also try WAP, and no password at all.

before i could tether my N4, i had to phone my carrier and get them to activate it.
this was despite being able to tether my old HD2 on the same account with no issues.

Ok here we go:
So I am sorry I did not remember this sooner, but my friend had this issue and here is the problem and solution.
I can only speak for Rogers, other carrier maybe different. The problem is with data package but not that tethering is not active (it is by default on Rogers) but that the data is wrong. Most likely you had an Iphone or Blackberry before, or one of these devices is still listed on your account as primary(you can;t change that, they just go by what did you buy from them last, then won;t put Nexus on it).
So with Rogers there 3 different data sets, for Iphone,for BB and for Android, you need obviously Android and you don't have it.
There probably some differences but the major once is that on BB one you get free LTE on android (on older once) but it wont tether probably with other devices,(actually my friend prefers LTE over tether so he capt BB plant on Note 2)
What you do is, call Rogers Tech support,(preferably not from your phone, so you can test it at the same time) don't tell them you have nexus 4, tell them it's S3 or Note 2(just a device they actually sell)tell them that you have (depending on your previous phone with them) the Iphone or BB data there, and you need them to change it to Android as your tethering not working. They can say what ever they want, but make sure they change it, even if they say it's BS, still ask them to remove and add it, but they should know what are you talking about. If the guy is a real stubborn, asking to put on a different data plan, like flex or something just to try (make sure any changes they make don;t interfere with your payment or discounts on the account)
Once the guy/girl says it's done, turn off your phone after 30 sec. turn it back on and check if it works.
Worst comes to worst, which is shouldn't because I know for a fact they have three different datas, ask to speak to Customer Relations Department, tell them your friend had the same problem and that's how rogers fixed it.
In fact, no mater if the Tech fixes it or not still speak to Customer Rel. Dept. and just tell them that you are not happy with the data, it gives you problems, and that Telus offered you a same plan for cheaper and $350 credit for cancellation fee if you move, so you would like to see if you can get $15 off your plan.
Hope that helps.

Thank you!
After dealing with 4 customer service reps, all telling me everything was fine, I called, used your advice, and everything is working.
This was also affecting my MMS messaging, not just tethering.

Still having issues with my new nexus 7 2 and trying to tether my nexus 4. Rogers tells me there doesn't appear to be any restrictions on their end.
I was looking into the APN settings, I don't really want to mess with those but it might be my only option?

Amazing! I looked for solution for a while now, couldn't find it anywhere, and yours worked like a charm!
Although I'm from Israel and my phone carrier is Pelephone, it was my problem aswell. I contacted them few times about tethering without success, they said it can't be blocked by them, neither they have special data plan for that. After I read this post I contacted them again and asked them to set my phone as Nexus 4 on their data base. I turned off my nexus, wait a few, turned on, tried again and it finnaly worked!!
Many thanks!! :angel: I'm surprised this issue isn't so common on the Internet.

t-mobile US USB tethering (not wifi)

Tried getting an answer on t-mobile's forums but it seems mostly people *****ing or having no clue about anything so couldn't get a straight answer and thought someone might know here.
I heard someone say wifi tethering is fine, but if you USB tethering and use more than 100mb they charge an insane per mb fee, does anyone know if that's true?
I just would rather be able to use USB because i've noticed the wifi on it (at least with the t-mobile US rom) is horrible and has issues holding a connection often even when a foot away from the computer connecting and I also noticed while HTC's wifi router is running the phone itself has no internet access and won't download emails, etc which is very annoying, but window mobile's internet sharing tool doesn't have that issue.
I use USB tether on a daily basis, and have been for at least the past six months. I just started using the feature on my Leo, but I've been with T-Mobile for over a year now and been tethering on a MT3G and Nexus One. I'm 100% certain that I've gone waaaay over 100MB, but I have never seen any additional charges on my bill because of data usage.
Edit: Actually, after thinking about it...each Leo ROM is over 100mb soo...
great! thanks, tethering has been my biggest concern switching to t-mobile with them lacking any official tethering plan, I don't mind paying for it if they offered it and did on at&t, just so long as I can do it averaged 4gb on at&t.
now if only the radios on the stock rom weren't so bad, and I'm kind off leary on the whole rom flashing thing.
I wouldn't be too leary on flashing. I was a bit when I first did it with my first phone. But I did a lot of reading, double/tripple checking. With the HD2, I'm just giving it enough bake time so people work out any kinks in flashing first.

id be really interested in how they could tell the difference.
With an unlimited data plan, almost all US carriers kind of turn a blind eye to tethering (or suspected tethering) as long as you stay under the technical data cap (~3-5GB for the US carriers, I think 5GB for TMo).
I've tethered my MT3G with T-Mo for a long time, using nearly 1GB in a day as a wifi router for friends in an apartment, and heard absolutely nothing from TMo.

Well I did try once with my Fuze unsucessfully and worried to try it and brick my HD2 because i've found the instructions i've seen on here not very clear, like I know there was one program it said to flash before flashing rom's but it was only for certain roms and none of the roms seemed to indicate which was the proper way to flash that specific rom :/

Well I know when I had my HTC Fuze on AT&T when I would tether the phone it showed 2 different active data connection, I belive one was called internet and one data, though I don't see that on T-mobile, just have internet so maybe they can't, just kind of want to be sure and not get some crazy bill.
I'm also not worried about a limit or being charged for it, but was hoping for faster connection speed with TMo. Averaging 800kbps 2 days after receiving my HD2, about equal to my omnia with verizon.
Havent readup on it much yet, but is the 7mbps a TMo rarity?
And I too plan on flashing a ROM, trying to wait...
Anyone have a cab to add the USB internet sharing to the menu that pops up when I connect to USB on my computer? It only shows 2 options, and on custom roms it shows internet sharing. Also has anyone found a cab to add the WIFI Router to the Sense Wireless Settings menu? Thanks
I have been tethering for almost 7 years with T-Mobile.
The OP stated 100MB may refer the original web2go thing. The truth is: you'll be upgraded to smartphone data once you go over 100MB, but it's never enforced.
To tether with HD2, you need to use internet sharing in tools sub-menu. T-Mobile Data or Internet doesn't really matter.
It's said there's a 10GB softcap and you're throttled thereafter till the next billing cycle, but I don't hear anybody (including myself) got hit yet.
You can tether, just use it sparingly. It's not your home internet replacement.

When I went into the store an got my HD2 at launch, The sales rep and I were talking about tethering...he said that he tethers all the time on his rooted Nexus and now on his demo HD2 that he was given. He said that he has never run into a problem and has never heard of any customers having an issue with billing. He said that he uses anywhere up to 3-4gigs a month and personally I have never even come close to that. As the quoted poster put it "It's not your home internet replacement" so don't use it as such...
...he did say that they know when you do it though which is a bit concerning...and if you call customer care with a problem concerning tethering, they will not assist you.
...the first rule about tethering, you don't talk about tethering...

lmao!
and I gotta remember my days of 14.4kbps tethering with sprint (tarred and feathered for talking about it back then) and be dang happy with 800kbps!... its stupid FIOS in our home making me think 7mbps is subpar.
I asked Customer care and they were quite helpful. I have the legacy data plan for all windows mobile phones. The plan is 19.99, but is grandfathered into the newer data plans that are going at 34.99. Now, for my plan at least, they told me I have a 10GB bandwidth limit and can use the 3G network as well as tethering is supported. I consider myself absolutely lucky with that data plan. And from what I heard, if you hit your limit, you will be dropped off the 3G network and will run on the EDGE until your limit gets resetted.

Thanks, but I was looking for the Manila Settings Tab - Wireless, where it shows the Wifi Sharing. It's probably cooked in some roms that I used in the past...
I did a search for HD2 tether, and came up with this thread. I don't see my question answered in it though, although I may have missed it, or somewhere else.
My question has nothing to do with whether T-Mobile allows it or not. I have tethered for years on T-Mo (with other phones), with no problem.
My question is simple and basic--How to tether on the HD2?
Since this thread is about USB tethering, my question here could simply be about how to USB tether, although I would also like to find out the best way to Bluetooth tether. (I read something about wi-fi tether in this thread, and have no idea what is meant by that.)
For USB tethering, I assume a driver is needed, for the computer to see the phone connected via USB as a modem. In fact, I probably have an HTC USB driver from previous HTC phones I had, like the MDA (and even the Audiovox SMT5600), but I don't know if there is a newer driver more suited for the HD2. Where does one get the USB modem driver for this phone?
For BT tethering, I think there are two ways-Dial-Up-Networking, and a newer way, I think ICS. I have only used DUN before. I think I might have read that the other way is better though. Is there a thread I missed, with a guide to BT tethering with the HD2?
Thank you for your input.

And it has indeed replaced my home internet. Pings suck for games, but other than that, it's completely serviceable.
The way if was explained to me by TMO folks, is you essentially have an uncapped bandwidth limit. However, once they see you hit 5gigs for the month, they will throttle you down somewhat.
As far as tethering goes, TMO is probably one of the friendliest towards it in the US. Just don't call into 611 asking for support or how to tether, they wont throw you under the bus and start billing you extra, but they just don't officially support it, you might get a rep in a good mood and willing to help though
I've been tethering for at least 6 years on TMO, started with a seirra wireless GPRS aircard then upgraded to an EDGE card. I would swap my SIM out of my phone when using the card. technically not tethering i guess, but then I got a Samsung phone that supported bluetooth and always tethered with it to my laptop and winmobile PDA

Can anyone confirm they have had their accounts changed without their permission? And if so what plans did you originally have? I don't see how att can see the difference. When I look at my usage, it looks just like the usage as when I am browsing on my phone.

AT&T has changed some people's data plan automatically?
from what i understand thats when people have been trying to use the hotspot that came with the phone by changing the apn and running with it this is differint its an app that is seperate from that to my knowledge someone correct me if im wrong
Did you assume that the APN method changes the plan or did you actually see someone say that their plan was changed as a result of that method?
You seriously need to learn how to use punctuation and grammar. I had to read your last post a few times before I could clearly understand what you were trying to say.
I have been using the APN since Tuesday, very heavily, I have Unlimited Data plan. No changes to my account.
I also have been using the WIFI hotspot for hours at a time with the unlimited plan and checking my account online shows no changes to date.
"I don't see how att can see the difference."
My IP is a bit rusty but I *think* any packets (any data) that are being routed through your phone to some other final destination (a tethered computer) will show the IP address of that final destination, rather than the IP address of the phone. And the phone will be shown as a part of the route.
So...it could be as simple as examining the packets and looking for the ones that aren't targeted to end at the phone. If someone bothers to look for it.
If the tethering uses NAT (which I'd imagine it does, though I didn't verify that) you wouldn't be able to tell the difference IP-wise between the phone and the host using the computer.
If you go on-line to your ATT account and check under current data usage, you will find that under data usage it will state in the TO/FROM column "phone" with non-tethered usage and when tethered it states "wap.cingular." It looks like a pretty big marker but so far, no changes have been made to my plan.
Sure here is a similar mod that used to work for verizon - verizon quickly fixed it
http://it-john.com/home/technology/android-technology/free-tethering-for-htc-indredible-on-verizon/
Since you are using login information, they can simply check your phone info and when they see you logging in with WAP credentials yadda yadda
Anyway - mine changed twice - on 2 phones - but i viewed my account data using the myAT&T app. http://market.android.com/details?id=com.att.myWireless
Just my experience.

That's interesting. I wonder if that's something new they changed. I swear when I looked a few days ago that all my usage was shown as wap.Cingular. when I look back before I got the attic all my blackberry phone browsing was shown as wap.Cingular also.

I just wish they'd stop charging for tethering. It doesn't make any sense to me. Yes, having your phone tethered to a laptop or the like means you could potentially use a LOT more of the bandwidth a lot faster and for a lot longer.... but if you have a limited plan, then you're only paying more for your plan a lot faster. That's the only reason i can see that they DID ditch the unlimited plans as a selectable option for people who haven't had it before. Little bit more incentive to go for a tethering plan.... to pay to use your bandwidth quicker.
Was actually just comparing all the apn's on my phone and noticed something.
the default select APN has the apn settings as "phone". So I went to the APN that we created for tethering and changed the apn setting from "wap.cingular" to "phone".
Saved the setting, checked connection, and then fired up tethering. Still seems to work as I am tethering to my laptop right now making this post. I will watch my online usage then next few days to see if it shows it as "phone" or as "wap.cingular". Pretty sure it will change to all showing "phone", so we might want to change the directions if this holds up and works.
Just something else to help hide what we are doing.
Nice find!

I have both "phone" and "wap.cingular" data usage in my history, but I haven't done any tethering or added any APNs. Could that be because I was on Edge at the time? The APN for wap.cingular is labeled as AT&T US while the APN for phone is AT&T US HSDPA.
And just to clarify, when you are tethering using the added APN are you just using the stock mobile hotspot app?
Yes, using the stock hotspots app. I don't think you can use any market ones unless you have the phone rooted.

Fall From VOIP Heaven

I fulfilled my quest to get a data only plan on the Atrix by buying an AT&T mifi and just putting the SIM card in my atrix. This required creating a new APN for isp.cingular, and for about 4 months this worked great with a pure voip setup.
A few days ago something happened. My Atrix seems to be stuck on EDGE. It will no longer connect to HSPA in the same locations that it used to be H+ 24 hours a day.
The basics have been covered: power cycling, airplane mode cycling. No use. The SIM itself seems okay since I tried putting it back in the mifi unit, and it got 3G like normal. That also rules out a tower problem.
Anyone have any ideas? I feel like an ass now since I bought the mifi on contract.
You can call At&t and switch it to a voice plan with an hspa data plan so you can use your atrix.
Kind of admitting defeat though.

Perhaps try flashing a different radio on the atrix. It could be an Incompatibility issue ? Worth a shot I would say
Sent from my MB860 using xda premium
So, I tried flashing different radios. No luck. After that I thought maybe some fresh ROMs might do it some good. No luck on Alien, and then I installed CM7 and noticed something interesting. The "Use only 2g networks" setting is stuck on. I turn it off, go back, and soon as I look again it's on. Is there something special you have to do to save it, or could this be pointing to an underlying problem?

Nothing special is needed to save it. It could be throttling by AT&T do to your imei being that of an Atrix vs a mifi.

I suspect att has caught you with imei check and you should try with other sim card.
but i suspect it may not work.
why not use it with MiFi only?

The problem with the mifi is its terrible battery life. It only gets 4 hours in hotspot mode. If it could last as long as my phone, I wouldn't even mind carrying around two devices, but it doesn't.
Anyway, great news. After listening to everyone's suggestions I took the SIM out of my phone and noticed that I was then able to properly disable "Use only 2G networks". So, I ordered a new AT&T SIM online, called and had it activated, and now 3G and H are working properly again. And along the way I fell in love with CyanogenMod.
I expect I'll probably have to repeat this process every few months if they continue to slap down my SIM cards, but I consider it worth it for not having to pay for a voice/text plan. I am still on contract, but to anyone who is considering doing something like me, T-mobile recently started offering a $30 a month plan that gets you 5 GB of data, 100 minutes, and unlimited text, and it's for phones! The only hitch is that it's a month by month thing (no contract) and it's promotional, so who knows when they'll decide to cut it. But personally, I'm hoping it's a sign that carriers are finally moving in the right direction.

I setup a google voice enabled PBX with pbxes.org, back when they let you make them for free. I know for a while they stopped doing that; not sure what the current policy is.
Basically the pbx pretends to be a google talk client, so when someone calls my google voice number it goes to the pbx. Then I have an extension on the pbx that I register on my phone with the native android SIP client, which on CM7 works like a dream. Seriously far smoother and more reliable than sipdroid or csipsimple.
Oh and this does work for outgoing too, but if you're using a solution that doesn't (like google voice -> sipgate/ipkall -> pbxes.org), you can get around it with an app called Google Voice Callback. And it's still all free.

In 2.3 they added SIP calling to the android OS. It's not an app. Of course, in stock android it only works on wifi. Cyanogen unlocks its true potential by letting you use it on cellular too.
In my experience, on stock ROM SIP is an epic fail, both native and via apps (tried acrobits, sipdroid, csipsimple, sipagent). There is something funny about moto's audio routing stack, its not a network or settings issue.
Same settings and SIP providers - yes I tried two lol - , same apps, same network i.e. home Wifi, 100% perfect with nexus one. So I'm sure its Atrix specific. This happened on both stock 2.2 and 2.3 AT&T.
Custom ROM fixes this, CM7 native SIP works perfectly.
Can't remember for other ROMs, but they seemed to get apps working if not native SIP.
YMMV

[HOWTO] Bluetooth Tethering between Tab and Smartphone

Since HC3.2 there is a working bluetooth pan profile implemented.
Android Smartphone:
( REQUIRES ROOT )
-> download wireless tether for root user from market
-> install and enable bluetooth in configuration
TAB:
-> goto bluetooth settings
-> after pairing there is a small icon on the right side
-> tab will use phones internet conection via bluetooth
advantages:
no extreme battery drain like with a wifi hotspot
stable, fast, like a charm <3
tested with i9000 (semaphore kernel) and a500 with thor's hc3.2 rom
I've gone to the market and searched for "wireless tether for root user". There is nothing with that name that shows up. I get a lot of results but nothing that I see that makes me think it is the program you are talking about. Could you give us more info on which app you are talking about?
Thanks.
I think its called wireless tether.. if you cant find it on the market they might not be allowed in your region. do a internet search they both have websites.. They are also free apps and someone might have the files they can post for you..
if you do not have root try pda-net beta..
just do a search on the market for tether app. and you will find many of them . from android rooted phone to tablet rooted wireless tether or barnicle is the two most popular..
from non rooted only choice is.. pda-net .
I have never tried wireless tether or barnicle over bluetooth or usb.
Good luck..
wireless tether is the only app which supports bluetooth pan.. pda-net beta dont work for me and is very strange because you have to setup a proxy everytime you want to use it..
im not allowed to post external links because im new ^^
go in market and search for: "wireless tether"
https://market.android.com/details?...lt#?t=W251bGwsMSwxLDEsImFuZHJvaWQudGV0aGVyIl0.
edit: link seems to work^^
Thanks Erica. If you can see it I should be able to also since I am also in Louisville. I'll look at some of the tether apps to see if they include bluetooth tethering and give one or more a try.
---------- Post added at 11:28 AM ---------- Previous post was at 11:22 AM ----------
Thanks schlumpfchen. I went to the link and the app showed up. It doesn't show up if I do a search. The market also won't let me install it on my phone, a Samsung Captivate. It show as being compatible with my Acer a500 but not with my Captivate.
EDIT: I managed to find wireless tether on the web and downloaded the latest version, 3.1 Beta11. It installs as WIFI Tether and there are no bluetooth options for tethering. What version are you using?
EDIT AGAIN!: I removed that version and downloaded 2.07, the same version that is currently in the market. It installs as Wireless Tether and does have the bluetooth options. I do not get a good enough phone signal to test anything here at work but I will be trying it later. Thanks for all the help.

WOW im not sure why its not showing up unless at&t has somehow got your phone banned from that app. Is your phone stock . is the phone rooted..
this app is also available on amazon market. and there are a few other non google places. but you must be able to side load apps.. PRP Area here by the way add me .
My last phone was an samsung i9000 (rooted, euro) and i was able to download (germany) wireless tether...
on cm7 based roms the bluetooth tethering seemed not to work..
now i own a htc evo 3d and it isnt working too (kernel dependent)
Maybe it didn't show up because it wasn't compatible with my phone, at least according to the market. Either way, I found the correct version out on the net. I'm running team hacksungs ICS ROM with non market apps enabled so had no trouble installing it. I'll have to wait until outside the office to get a good enough signal to test it. Thanks to both of you.

AFAIK AT&T has explicitly requested Google to not allow installing any tethering apps on AT&T mobiles because AT&T does not allow tethering on their networks. AFAIK the same applies to Verizon, too, but I am not entirely certain of that as I'm not an American. (Thank god!)
That sure sounds like it could be the issue. I'm sure they don't want anyone tethering unless you use their app so they can get paid monthly for it.
3rd party apps implement "unofficial" tethering.. some preinstalled apps use another way for data exchange so you have to pay some extra fee for it^^

Another reason i DO not use one of the big cell carriers.. I say if you get out of your contract. ditch [email protected] .. take yourself to cricketusers.com and get your phone unlocked and flashed over to Cricket wireless.Then be done with it ..
they told me they DO not care as long as you do not abuse there services.I have at&t work phone . well when i was working and my cricket phone is better signal.. good luck... I so hate being told what to do by others.. if i pay for something i wish to use it how i want.
I went back to the market and looked at it again. It did not say the app was not compatible with my device, it said the app is not available on my carrier so it is restricted by AT&T. Thankfully google's code labs doesn't care who downloads the APK file.

I do not recommed doing that. AT&T monitors their network for tethering and if they notice you're doing it without using their app they can slap you with a really hefty extra fee.

I'm glad I live in Finland. Here the carriers EXPECT you to tether and they do not restrict it in any way or form. They also offer contracts in several forms, like e.g. you can surf with maximum network speed but you're limited to 20GB a month, or you can surf with 1MBit/s speed but can upload and download as much as you want, etc. etc.
Finland rocks.
accounts here at Verizon wireless is like this as well.. they change like 10.00 a month for tethering.. with unlimited full speed for x amount of data. then they will slow your data rate. I think eis similar to them all except sprint.. THOU Sprints service sucks in my area.. they offer a account for 70.00 a month TOTALLY UNLIMITED . You can tether as your home wireless modem to your whole network . unlimited data at there FULL FASTEST SPEEDS.. i Have a friend using this plan. its the only internet she has.She does use it constant as she is a network admin for large company with many locations.. before this plan she was spending 500 plus a month on her cell bill...
There are options . legal options but all add cost to your account..I however belive tethered or on the phone itself you should be able to use your data allowance tethered..
you can connect two androids with bluetooth in settings, create an interface by running pand -c mac-address-of-host, find out the ip of the host and set up the gateway on the client. dun can be achieved too but you have to set up profiles, an interface with rfcomm and run pppd device call isp. I get about 0.7mbps down with either which is why i use usb with my a500 and its awful wifi
I'm on Verizon and I use the SVTP app to tether between my a500 and my Galaxy Nexus with no problem. I don't believe it requires root
Perhaps someone can help me with something here...
I just started with tethering... and I am wondering.... what is the difference between wifi tether and bluetooth tether? I have both on my phone.
Are they both the same thing? Why have both?
Is bluetooth tether just for rooted phones? If so why have the option on android if just for rooted phones....
hey, i know this doesn't always work on every device. i'm running an LG Optimus 3d (p920/p925) with my a500. is their any tricks or tips to get this working?
thanks
I Bluetooth tether my Samsung Precedent with my A500... I use PDANET Tablet on my a500 and FoxFi on my phone... works great. both need to be rooted.

HTC1 and Media Link - Tethering Required!

I'm having a WTF moment.
Got my preorder One last Thursday and have been having trouble getting it to connect to the Media Link HD dongle.
First, it seems to connect and pass through image to the TV but I get a message saying something like "be sure the TV is properly configured". Then, I get other messages saying that WiFi Hotspot needs to be enabled and to go to the AT&T website, or dial 611.
After over a half hour with a service rep, I was told that the Media Link requires a WiFi hotspot, which in turn requires that Tethering be provisioned on the account... for another $20 per month for a 5gig plan. Suffice to say I told the supervisor I was eventually passed along to that the practice of incentivizing customers to preorder and stay with the company by offering a free dongle only to be trapped into spending more money every month to use it is a tactic worthy of Tony Soprano.
The part that confuses the hell out of me is that if the Media Link and phone both connect through my WiFi router, why would Tethering/Hotspot to connect to the AT&T data network even be necessary?
So, anyone else have this problem and a workaround?

Like? Not even sure where to begin. The phone connects to my router just fine, so that's not it. This is a real head-scratcher.
Have you tried changing out of game mode? If its not that they are forcing you to use hotspot to spend more on monthly charges ergo why it was free. Or one more possibility its just a mistake in the software and they will fix it in a future update. I'm glad I don't have att. I hope for the best you don't have to use your own data, just to use the media link

No, you definitely do not need tethering / hotspot on your account. I use the Media Link HD with my One (AT&T version) without any issues and I don't have tethering on my account.
Make sure the firmware on your MediaLink is up to date and both it and your One are correctly connected to your WiFi hotspot. Also, be aware that any complex security settings on your hotspot could give you trouble.
Sent from my HTC One using xda app-developers app
The firmware version of my adapter is 5.19.103.1 with no unusual settings on my router, which is an older Liksys - the blue one with the dual antennas.
The dongle recognizes my network name and my One connects for a second until a dialog on the phone reports that hotspot is required and to go to the AT&T website or call 611.
I have never applied "unusual" settings in the router other than naming the network, broadcasting SSID and applying WEP.
Any help is appreciated.

I have tethering on my plan but I did notice that the flash wouldn't work while it was connected to my MediaLink. It gave an error message saying that flash isn't supported while hotspot is enabled.
would also like to know how to get around this hotspot error.. I've tried different security settings on my wireless router; what I haven't tried is using NO security to see if that helps. will try this now and update post!

Yeah, this is getting wierder by the moment.
Likewise I tried disabling security on the router with no results.
I just installed a tethering app which requires root (suggesting to me that it works around any block at&t put on the ROM), started the link and it disabled tethering in favor of WiFi.
Looks like one of us is going to be on the phone with AT&T and/or HTC this week. I already have about 45 minutes invested with an appointment for Wednesday to discuss the tethering issue. Where I'm concerned, how I use my monthly bandwidth allotment is my business and they have no right to dictate limits to what I pay for within the confines of my plan.

Have you tried putting the phone in airplane mode and then just turning on WiFi? I wonder if its just because the Media Link sees the hotspot on the device as an option, even though it isn't enabled or activated.

Have the same issue, and putting the phone in airplane enables me to connect it with my tv but only for about 20 seconds. After that, the phone will
tell me that there's something wrong with usb tethering setup thus kills the connection. So technically, connecting the media link with the phone
triggers tethering on the phone, either usb or mobile data which are somehow blocked by atnt.
With regards to gaming mode, it's a mode on my tv that draws in extra frames to smooth things out, only it had a hard time working mostly lag.
As for the media link I doubt I'll need one, as my tv is a D8000 so runs wireless anyway.

Pretty much for the moment. I tried flashing M7's ROM and it worked fine. Seems AT&T has blocked the WAP/Tethering function in either the kernel, radio, or the ROM. So, the solution would seem to be:
1) Find a ROM you can live with and flash it.
2) Find a Kernel (or radio, if that's what it is) that works with the stock AT&T ROM and flash it.
3) Wait for AT&T to get their heads out of their asses to realize that they're screwing their customers who have peripherals like the Media Link which connect via WAP and fix it in an OTA update.
Rumor has it that there's a 1.29 update out there somewhere. Let's see what happens. In the meantime, those of us who are in this boat should call AT&T's technical support and give them an earful for pushing disfunctional equipment on us. There's plenty of advertising hype from both AT&T and HTC about how cool the phone is, but nothing in the advertising literature that says how they crippled the phone.
I'm in the same boat here. There is another thread about this:

If I can't figure out a router configuration that fixes it, I may experiment with "rooting" and then trying to kill the com.htc.tetheringguard app. I'd definately rather have it work through my wireless router like it should, but not if I've got to leave the network open/unsecured!

I am rooted, froze that app (along with all the other AT&T bloatware) with Titanium and it still doesn't work - no link action, no tethering, either.
Frankly, I'm pissed. I understand why they inhibit tethering, especially for those of us who are on unlimited data plans. There are always guys that will abuse it. But this phone came that way from the factory, which means that even those who are on 2G plans are screwed. In either case, if I'm paying for data, it's up to me to decide how fast I want to use it, the same way as if I were to pay for a tank of gas in my car, it's not up to Exxon to tell me I can't drive on the highway.
I was supposed to have received a call back today from the AT&T supervisor to discuss options, but (surprise!) no call. Looks like I'll be having a word or two with them tomorrow - and I have half a mind to demand a full credit on the purchase price of the phone for the amount of time I've spent jerking around with them about this.
