Wireless N problem

My Nexus 7 doesn't seem to connect in wireless n. Here's the situation. When my router (Linksys WRT300N) is in mixed mode 2.4GHZ , the Nexus connects fine (using WPA2 security) with a link speed of 54Mbps. If I change the router to Wireless N only (2.4GHZ) , the Nexus can't connect. The Nexus sees the router and I put in the password but it won't connect Now, my HTC Sensation works fine in Wireless N only mode. So is my Nexus only connecting in G?
Anyone else having this issue?

I'm having this exact same issue with my Galaxy Nexus and found this thread with a Google search. I am also wondering what the issue could be and will post back if I come to a solution. Maybe this is related.

Same here, my Nexus 7 won't connect over 54Mb/s, laptop and Epic 4g touch will just fine. I'm starting to think that either jellybean is broken, or they lied about the wifi capability of the nexus 7.

Mine says 65 mbps so it seems to be on 802.11n (note that this chipset doesn't have 40 mhz channel support so 65 mbps is the maximum). I have a Cisco E4200 router.

I have the exact same router and had connectivity issues. If you're familiar with flashing stuff, goto Dd-wrt and flash the aftermarket firmware (read everything!). Fixed all my problems and UI is much better than Linksys' limitations.
Good luck!

Not so sure its the router
I have this problem too on my Nexus 7.
I've a Netgear DGN3300 which is a/b/g/n 2.4Ghz and 5Ghz. My Samsung Galaxy 2 phone connects at speeds up to 65Mbs fine. My Nexus 7 refuses to connect at anything abover 54Mbs. My laptop connects all the way up to 300Mbs with no problem.
I can have just my phone connected at 65Mbs and nothing else using Wi-Fi and still the Nexus refuses to connect at anything beyond 54Mbs.
While I accept it may be a router problem, with a phone and a laptop connecting fine at N speeds and the Nexus 7 not... it looks like a Nexus 7 issue to me.
If its not really capable of consistently making Wi-Fi N connections then it shouldn't be advertised as such.

Please change encryption type from TKIP to AES from your router settings, and you will have 72 Mbps......

My Wi-Fi is already set to AES which is why my phone works fine at greater than 54mbs speeds.
The N7 simply refuses to connect at anything more than 54mbs.
Maybe I have a faulty N7

Hi I have the Exact same problem and my router alreay has dd-wrt on there, and tried different encryption aswell.

How do you measure the connection speed? ...
You said, it can connect 65Mbps , 54Mbps ...

All but one of 5 access points I tested at home are set to N only. The WRT54 was not. I have no problem connecting to it and getting good speed while having only a good connection...
At work the access points are set to mixed mode for the very wide selection of devices that need to connect to it though.

Try changing the router channel N uses. I've noticed devices that have "N" not connecting if the channel is above 149.

Edit: Just tried and I didn't see a difference, its worked in the past for other devices like my old Asus netbook. The Nexus 7 has N support right?

FWIW, same problem here. If I put my dd-wrt wrouter into NG mixed mode, my nexus 7 connects fine. If I go to N only, in any frequency, it won't connect. Security is set to WPA2 and AES encryption. It can see the network, but won't attempt to authenticate. I have tried setting a static ip as well. It worked in mixed mode, but not n only.
My other samsung phone connects to the n just fine. There is without a doubt something wrong with the nexus 7.

for those with problems... can you see if the wireless N channel width is set to auto or 20mhz or 40mhz in your settings? If it's set to 40mhz can you try 20 or auto?

Is anybody else having wifi issues?

Literally received my N4 about 30 mins ago and Ive set it up etc. Ive noticed that the Wifi seems to be weak compared to all my other devices I have around me (it goes up and down and actually dropped out altogether once).
Anybody else have wifi issues?

hmm...i think so, yes
Gnex speedtest on wifi 5.19Mb
N4 speedtest on wifi 2.11Mb
not an "issue" but definitely slower

I have seen an improvent over my HTC Desire. With my 50 Mbps DL / 5Mbps UL
My results:
With WiFi N: 45 Mbps download / 5 Mbps Upload (The speedtest app just gives random download speed as I don't even get to see the download speed bar) Singal is between 40 and 60% according my router.
With WiFi G: 19 Mbps download / 5 Mbps Upload (Pretty much maxing the G bandwith) signal is 95% as the router is in the same room.

I just got phone this morning. I get my max 25 mg dl 5 upload and have had no issues

Mine was working poorly just as you described. I turned off WiFi optimization in the settings (says it helps with battery life, so I'm assuming this weakens WiFi) and I looked around in my router settings. It was set to 145Mbps (neighbor-friendly mode apparently) and was giving me less than 5Mbps up or down. After bumping it up to 300Mbps (performance mode), it is now giving me full speed for my 30/5 connection.

I'm having trouble connecting to my cisco router. It would say either "obtaining IP address" or "authenticating", then the connection breaks and it attempts to reconnect.

No issues for me.

I had an issue on mine where it lost connection with my wifi router, then kept showing no networks in range (usually there are around a dozen showing up due to neighbors). I tried turning wifi on and off, going into airplane mode, finally had to restart the device entirely to get wifi to detect any networks again. Hasn't recurred, but it does make me concerned.

Seems good to me:

I'm having problems connecting to my Buffalo router with WPA2 security. It connects just fine to my guest network that uses WEP authentication on the same router, but it just says authenticating or obtaining IP on my main network. My router is a BUFFALO AirStation HighPower N450 - WZR-HP-G450H using DD-WRT... Is Buffalo crap and that's my problem?? My Gnex connects to it fine.
I've tried disabling/enabling wifi, airplane mode then out of it, and rebooting my Nexus 4 without any luck.

I had this issue but toggling wifi fixes it.

I have a 30mbps down 5mbps up connection at home and I get those speeds on my phone over a wireless n connection at 5ghz. No issue with wifi at all.

[Q] 5GHz WiFi on Nexus 10?

Okay, so we know that dual band WiFi is listed in the Nexus 10's tech specs, and I've had two Play Store tech support people confirm that it should indeed be 5GHz capable, but it just won't recognise or connect to my 5GHz network.
I've had 3 Nexus 10s now (all 32GB), and the behaviour below has been consistently observed on all of them, both in 5GHz only mode and Auto mode:
(The behaviour is identical on JVP15P, JOP40C and JOP40D)
- Does not show my 5GHz network in the network list
- Will not connect if the SSID and key are manually entered
- inSSIDer shows the 5GHz band as empty
I know this is not being caused by an issue with my network as I have half a dozen 5GHz capable devices all working on 5GHz without any problems at all, so my question is; has anyone successfully connected a Nexus 10 to a 5GHz WiFi network?
Thanks.
13 Jan 2013 - Just to update, it appears there could be ranges of channels the N10 will not operate on. These are 52-64 and 100-140. Channels outside theses range appear to work fine.
I would be especially interested to hear from anyone who has got an N10 working on channels 52-64 and / or 100-140.
Thanks.

I have a netgear router my nexus 10 connects to the 5gHz at 300 mbps

I have a BelkinN600 and switching to 5ghz is not an issue for me as well.
Do you have your Wifi frequency band settings on your N10 to run auto or strictly 5ghz? Maybe its checked at 2.4ghz?

Thanks for the replies.
jjdevega - I've tried this setting on both 'Auto' and '5 GHz only' and none of the 3 tablets I have recognise my 5GHz on either setting.
It seems improbable that I've got 3 tablets with exactly the same WiFi fault, so I'm rather stumped as to what's causing this.
Would both of you mind letting me know if inSSIDer shows your 5GHz networks in the spectrum view?
Thanks.

I can verify that 5 ghz works beautifully with the Asus NT-56 router as well.

Make sure the Channel Width (on the router) for the 5Ghz signal is set to 20Mhz, not 40Mhz or Auto.

5GHz worked swimmingly on my Nexus 10. Maybe it's an issue with your router?

It is a configuration problem on your own router if it is not working.

Yup getting the full potential of the 5ghz

Okay, I've been digging deeper into this and I've turned up something interesting.
None of the Nexus 10's I have here seem to work on the 5GHz channels numbered 100+
My network resides on 100 and 104 usually, and all my other 5GHz capable kit can use these channels just fine.
If I set my router to one of the lower channels (I can force the router to 36, 40, 44 and 48) then the the N10's see it fine.
Can I ask what 5GHz channels people are using? Does anyone have an N10 using channels 100+ ?
Thanks.

Mine is using channels 36 and 157. Both are Asus routers. I can see my neighbor's 5Ghz also on channel 157. Time to switch channels I guess.

Thanks, that's really interesting
I'm in the UK so can't use 157 - it's not a licensed channel here and so is disabled on the router Whereabouts are you?
It's curious though - all the channels that require dynamic frequency selection (and transmit power control in Europe) seem to be inoperable on the N10 (channels 52 - 64 and 100 - 140)
36 - 48 are only licensed for low power use, and don't quite provide the range I need. My router chooses 100 and 104 when set to auto and uses them at full power, and this provides the range I need. It's a shame the N10 doesn't seem capable of operating on those channels.

I'm in the States (Houston, TX). Unfortunately I can't use 100 or 104. I just moved my second router to 149, the lowest of the block of channels above 100 available here. I can't think of a way to test your scenario here. Hopefully someone from the UK will chime in.

I can't remember the exact conditions, but I was able to not have my 5GHz network shown on my Nexus 10 one time, and have it shown another. I was messing with channel frequency though, but can't recall numbers used.

Huh. I tried 5 ghz and it doesn't work. Why? Do you need a faster internet to make it work? Ours is 117 MB btw.

Internet speeds shouldn't affect it; it's what wireless channel your router is using for 5GHz that matters. May want to play around with different values.

No worries, thanks for trying. Out of interest, do you know what channels your router would select in automatic channel selection mode?

No, those channels are all licensed for use in the US.
With 5GHz WiFi, a lot of the channels require the use of DFS as part of their usage license. These are 52-64 and 100-140. Because the selection of these channels must be dynamic you cannot force a standards-compliant router to use them, which is why they cannot be manually selected. They can only be selected by the router its self when it is in automatic channel selection mode. In Europe those channels also require the use of transmit power control (TPC).
It appears that the Nexus 10 will not operate on any of these channels, however the reason for this remains unclear.
That means the N10 seems to only operate on 4 of the 19 licensed 5GHz channels in Europe, and only on 9 of the 24 licensed channels in the US.

I haven't ever set mine to automatic. I manually set them to opposite ends of the spectrum, but I could try using auto to see what they do.

Nexus 10 = wifi FAIL

I have been fortunate enough to have enough Nexus 10's in stock at local walmarts to be able to validate a persistent problem with 3 32gb Nexus 10 Devices.
The first one I returned thinking it was simply defective. After the second, I suspected a bigger problem. Picking up a third tonight to do back to back comparisons has confirmed that there is a major problem with these devices and wifi connectivity/stability.
There are two problems that I've encountered on all 3 of these devices. The first is serious catastrophic signal drops at random times with no interference. The second is after network drops due to poor signal, reconnecting results in an endless Authentication/Obtaining IP loop regardless of signal strength that requires disabling wifi and then reenabling before it will be able to connect again.
The signal drops seems to happen consistently at a point in the house where I'm getting around -70 dbm. If I have a good strong signal, the drops don't appear as noticeable.
Network info: e2500 dual band router running 5ghz on channel 40 using WPA2 and 2.4ghz on channel 11 using WPA2. I've changed channels, set to static IP, set DHCP reservations, enabled 2.4ghz only, enabled 5ghz only. Unique SSID's for 2.4 and 5ghz bands. No router settings make a difference.
For good measure I swapped out the e2500 for an ASUS RT-N66U and attempted the same as above as well as playing more with security and channel width, antenna strength, etc. No difference. The issue is software/hardware related with these devices only. All other devices in my home maintain good strong signals. (cell phones, Internet TV's, Laptops, Blu-ray players, etc)
The signal drop was not observed on the newest tablet while it was still running 4.2. It wasn't until taking 4.2.1 that it displayed the same drops. The drops occurred on the devices independently of each other, again indicating it wasn't network related, but a device issue.
The pictures attached were taken at the same time for each device. They speak for themselves.

I havent had one single wifi issue with my Nexus 10. its running the newest 4.2.1 update. Im also using the Asus N66U Router. I have mine setup to detect both the 2.4 and 5ghz frequencies. Maybe ur security settings on the routers isnt playing well with the nexus? NM: just reread ur article. Not sure how i missed the entire paragrah on the security settings u used. Im not sure then. See if anyone else posts anything. Sorry i cant help any further. mine seems to be working awesome. Sorry about ur luck. Maybe wally world got a bad batch of them in then. I dont like buying electronics from there. for some reason, maybe its just me, the items dont seem as good even tho its the same thing. I always wander if vendors send walmart their 2nds. Who knows.

n10 working fine with asus ac66 router here. I use it on the 5ghz band.. I ran a couple of iperf throughput tests and it worked great in the same room as my router and also on the 2nd floor of my house...

This sound more like a problem with your router. No way are 3 in a row going to be defective...
EDIT: sorry if that sounded asshole-ish lol. I really think you are having problems with you router, so you should look into resetting it, and setting up your router again if need be. Try that, and try going to Starbucks or somewhere with free WiFi to test as well. Hope this helps

I would agree that it seems like a problem with your router. Either that or walmart is giving you the same tablet after you return it.
I know you have tried a lot but I would make sure you update the tablet and then do a hard reset of your router. Seems to me like you may have some issues with settings.

Before I updated my n10 to 4.2.1, I didn't have any issue with the wifi, no discconections, no lose of signal. Once I updated, I found out that all those problems came to me.

Even if it is a 4.2.1 problem and not his router, that doesn't mean the Nexus10 itself has a problem, just the current firmware. I'd be interested to see the same wifi monitoring done using a different router, and then with a different ROM (such as CM10.1)

Nexus 10 = No WiFi Problem...
for me with a Linksys N900 router.

Have the same issue on two N10s on a Linksys e2500...it feels to be software related

Does no one read?
Two routers, same issues with these tablets on both routers. These pictures are of TWO tablets back to back at the same time. 3 different walmart stores and 3 different unique tablets.
I've also been able to reproduce on my phone's hotspot by moving the phone far enough away that the signal degrades to around the -60 to -70 dbm. THAT seems to be the "sweet spot" so to speak. These drops when happening on stronger signals don't seem to be much of an issue unless you're streaming content. For surfing you don't notice the drop as your strength is still more than adequate. However, at these distances the drops result in freezing in browser and disconnects from the network.

Strange issue. I'm getting excellent WiFi results with my Nexus 10. My router is dinosaur... An Actiontec (not even 802.11N!) provided by Verizon with a FIOS bundle about three years ago. It's sitting in the basement at the opposite end of the house and I'm currently on the second floor. Signal seems just fine. No drops at all in a few weeks of heavy daily use. Any chance of some kind of RF interference?

Try only connecting to the 2.4 GHz and see what happens. It sounds from your post that maybe you have your n10 setup with both 2.4 and 5 GHz at the same time which is causing it to constantly pick the best signal and reconnect. For me personally, the 5 GHz range of my e3000 isnt good enough for me to even program my n10 to connect to it. I use 2.4 only.

No there shouldn't be any interference. I went over the possibilities with a Google support rep and the phones in the house operate at 1.9 ghz and one older phone at 5.8ghz, neither of which would interfere.
Additionally if you look at both devices at the same time, they were showing drops independent of each other so one device would be good at the sime time the other device drops...suggesting no interference.

Try switching the wireless to BG mixed and see how it goes...

Tried this and switched security to wpa personal and no change.

The is no specific issue with the nexus 10 WiFi. In fact, I've never had a better performing device signal strength/throughput wise. Look on the xda forums for any device, and you will find people with WiFi issues.
Ultimately, 802.11n is a specification and there are many different implementations of this. Some implementations have issues working with others, for a cacophony of different reasons. Seems you're having a bit of back luck at the moment.
First, you need to simplify your setup. Turn off any turbo boost modes, turn on any compatibility modes and reset to default settings. Turn off encryption. If you still have issues, research the advanced wifi settings of your router, and check nothing is set to a bad setting. If you still can't getgood results try a different router.

Done, Done, Done and Done.
The e2500 is a very simple router. No turbo boost modes, switching to the most basic n option, b/g option, specifying channels, turning off security, disabling firewalls, etc. doesn't make a difference.
And for the last time I DID try a different router using default settings and spent 2-3 hours messing with settings to see if I could find a sweet spot with it too.
Let me reiterate NO other devices of mine show signal drops. Laptop upstairs, Internet TV upstairs, Blu-ray downstairs, Two cell phones (Razr MAXX and SIII), etc. NONE, but ALL 3 Nexus 10's do. There is most certainly an inherent issue with all 3 of these Nexus 10s and they all share the same symptoms. It's a software or hardware design issue persistent on each of these. Even if I was able to resolve the issue with a very specific way of setting up my router, that would still be a huge FAIL. Your wireless device should be able to accommodate very basic and common security and configuration settings.
Instead of making a lot of claims that your device doesn't have problems and there isn't an inherent issue, how about some meaningful testing attempting to reproduce the issue as I've done?
Move to a range where you get -60 to -70 dbm, install network signal info and watch your signal strength on 4.2.1 for 10-15 minutes validating you don't have any drops and screen shot that.
Here's a back to back comparison showing the poor signal on the N10, yet great signal on a RAZR Maxx.

Well, if youre sure its not a router problem, you have 2 options:
Revert to stock 4.2 if you love running stock, OR try flashing several custom ROMs to see if the issue can be temporarily corrected until an official update arrives. (Optional 3rd: return your tablet to Wal-Mart for a full refund and cry yourself to sleep...the end)

Slow WiFi Speeds on Z5 compared to other devices

Over the past day or two I've noticed the download speeds on my Z5 to be slower than my other devices on WIFI. I'm not sure if it's cause and effect or just a coincidence but my phone fell 2ft/70cm when it slid off a table and fell onto timber flooring landing directly on it's back.
The phone has a case but I've done a factory reset and the problem still persists. Perhaps I've damaged the antennas but my mobile data appears to have had no change in speeds. The speeds varied on my phone over these 2 days ranging from 1-3mbps compared to the normal 6mbps i get.

Check your modem/router frequency that it use to send out the WiFi signal, and if you can change the frequency of your modem or router then change it to something else and do a Speedtest.
With a app called Wifi analyser you can see which frequency band is best to use when you connected to your Wifi.
If none of the above steps helps, then I have no idea what it could be, my Wifi works great anyway, getting 11 mb/s download speed from my modem.

Z5 connects to AC router with 866Mbit/s speed.
Speedtest reaches 100Mbit/s with ease on Z5.
Check your router.

Yep same as you, in addition if other devices are connected to the same band at slower speed they will also kill the speed of any other devices on that band

No the case won't affect this, in addition what are you actually talking about, your speed has gone to crap accessing files within your network, or are you talking about the internet. Because there are so many variables that can affect internet speeds, and a huge percentage of them are fully beyond your control.

I ran some speed tests at a friend's house to see what was going on and it seemed to show similar speeds against my friend's devices also connected on WIFI. I'm suspecting it to be a problem with my router but will run a few more tests with a borrowed router.

I am having problem with wifi, it says connected, but no internet access.
This is happening lately, mostly after last update .182
I don´t know but since then I have restarted my router for three times now, on laptop I don´t have any issues.

Speedtest gives me 219/200mbit/s on my z5 compact, could be better but it's acceptable for a phone

Speeds aren't bad for me. Relatively Cheap router. I have slightly higher speeds on my Laptop.

Other than home (which does not have any issue) I do not connect to other wifi. But on my recent travel, i've had the same issue as you connecting to various places which has wifi. I believe its due to router settings mostly.

I'm getting the opposite - mine's a disconnection issue. No WiFi connection issues but when I leave the house my E6653 sometimes fails to drop the WiFi connection for mobile data so I'm miles away with "Connected, No Internet" with a bang (!) next to the WiFi icon for my home SSID - far out of range! Turning WiFi off and on again sorts this out, i.e. mobile data connects instead.
Anyone else?

It seems fine for me but bluetooth and wifi on at the same time causes some imense lag.

My Z5 has BT on 24/7 (paired with smartwarch 3) and no WiFi lag.
Change channel on WiFi.
Channel 1 can mess up BT and vice versa.

I had to disable 5Ghz band on my router to connect a few ipcams. They do work now. But am I destined to have 5ghz band disabled if I want the ipcams to work?

Don't use same name on the the 2 networks, and make the ipcams connect to the 2.4GHz band.
Eg: 2.4GHz is named [email protected] and 5GHz is named [email protected]_5GHz, also disable band steering (if your router/ap supports it) if the cameras are supposed to be 5GHz "compatible" but actually don't work on it.
