[XT1528] Simple fix for stock WiFi tether/hotspot no internet issue on GSM networks - E 2015 General

tl;dr: If you have the WiFi hotspot issue where you can connect to the network but not get internet access try launching the stock verizon hotspot app and enabling it. Worked for me.
This is my first post please don't hate me for posting something so simple, thanks. :highfive:
I've been using my XT1528 as my main device for a few months now, preferring it to the Galaxy S4, but a major drawback was the inability to use it as a hotspot. I own a copy of easytether(for my linux machines) and PDAnet so it wasn't the end of the world but having to physically connect the phone is inconvenient.
Basically, you can enable the hotspot but it doesn't provide any connectivity. The standard fix for this on all phones is to edit the APN type setting to include "dun". When using the airplane mode trick to enable connectivity with a GSM carrier on the XT1528 apn changes don't stick for whatever reason. Half the time when I look an APN isn't even selected. I don't know if MMS works or not because I use hangouts to text but the SMSC seems to be fine. You also cannot enable the hotspot through any of the standard apps from the play store. FoxFi says it isn't compatible, etc.
So today I was playing around, testing M$' arrow launcher, and I launched the verizon "mobile hotspot" app on a whim, which seems to be just a shortcut to the stock tethering settings. It isn't though. When you go through this app and enable the hotspot - it works. I then disabled it, went to the tethering settings normally, enabled it, and the hotspot worked again. It makes no sense to me, I struggled to get this feature working for weeks and did a ton of googling for a solution. This app must temporarily add "dun" to whatever apn this thing is using because as a stock system app SELinux isn't blocking it. I haven't tried a reboot yet as I'm working on something with the phone and can't reboot it for a while.
With this solved I am in complete awe at what an incredible device I got for $25. From one hand usage, to the really nice feeling of the body, SD card slot, battery life. I am just so happy with this thing.

I haven't been able to replicate your results. I clicked on the red mobile Hotspot icon on the app drawer, set up and activated it. My tablet seems to connect, but the connection has no internet. This is driving me bonkers.

Bypass tethering check on laptop dock possible?

Would buy a laptop dock today if I wasn't being asked to relinquish my unlimited data plan in the process. Any way to bypass the tethering check? When I placed my phone into a dock it checks for either data tethering OR wireless network connection. My suggestion, but don't know if it can be done: a program that tricks the phone into thinking its on wifi when running 4g (a la 3g unrestrictor for ios). Is this possible at all? I know some people were asking about a similar program in order to run skype off of android in 3d a while back (prior to skype now accepting 3g for calls).
If I posted this in the wrong section, my apologies.
Moved to general as not android development
As off right now the laptop dock doesn't work with the work around to allow wifi tether without tethering data plan. Because it actually checks with att if you have the proper data plan. I've been searching for something similar to the iphone app my wii 3g.
Sent from my Motorola Atrix 4g XDA app.
i mean i can take my sim card out, use it with my dell streak, and connect the atrix with dock to my hotspot, but that's another phone i have to haul around... i'm still likely to buy the dock, $399 at amazon isn't all bad.
I just bought the dock, and I have some interesting notes to add:
When I plugged in my phone to the dock at the AT&T store, the dock did not check if I had tethering. When I then pruchased the dock, walked out to my car, and plugged it in, it did not check and I did browse the internet. I then drove home and tried again, and this time it told me that I needed a tethering plan. This all has to be a software check which runs at certain times, which leads me to believe that we can find and remove it.
I am replying to this while on the laptop dock. I do NOT have the tethering plan. I used this guide to enable hot spot and it works with firefox webtop.
Key for me was set up new APN, plug phone into laptop dock, THEN turn on hotspot. I am also using the atrix's hotspot with another pc.
edit: bah, turned off hotspot but i am still able to surf the web on the laptop dock. this is confusing.
I was able to get it to work somehow.
Here is what i did:
1) Created the custom APN for free tethering as described here.
2) Under APN type i put the following: default,dun,tether
3) i made sure my wifi hostspot is working properly (to make sure i setup the APN correctly). Once confirmed i shut down the hotspot app.
4) connected the HD media dock and launched webtop - it tried to verify the connection and kinda got stuck there.
5) i then changed the APN from the one i created to a built in one called "AT&T US Tether". at that point Webtop got access to the internet somehow (an no i don't have a tethering plan, i have an grandfathered unlimited data plan).
6) I immediately switched back to my custom APN after i saw webtop passed the connection authorization stage and voila...it is online via 3G/4G. I know for sure that the webtop is connecting through the custom APN and somehow - it works.

nice, i did something similar. but the odd thing for me though is that i turned off hotspot while docked and internet is still good to go. no wifi in sight so i know it's not picking up anything else.
Here's what I did.
1. Setup the wifi tethering hack (custom APN - AT&T with type default)
2. I docked it - it goes into - checking account status for webtop etc.
3. In the settings of the webtop (left of wifi icon, the little gear icon - go to advanced and then network proxy - change Location from Cellular to Default
That did it for me.
Hope it helps you too

Working for me as well Followed your directions exactly.
THIS WORKS! Awesome find, now I don't have to give up my unlimited plan.
So I've been going back and forth on what phone to get. In the end, it sounds like the Atrix has nearly as bright and colorful a screen as the Infuse, has a smaller device footprint, and still has gorilla glass. So I came to xda to see if...
1) Can I sideload apps?
2) Use the laptop dock without giving up my unlimited data plan?
3) Where is it cheapest to purchase the phone and possibly the dock off contract?
Seems like 1 is possible with root and upgrades, and 2 sounds possible as well. Are you having to go though each of those steps EVERY TIME you want to use the dock?
And if anyone has any suggestions on cheapest availability for someone in Washington State, I'd love to get this from somewhere tax free if possible.
Thanks in advance.

Frustrated! Help with tethering

I know it's not rocket science. I consider my technically sound.
But for the life of me, I can't tether my Nexus 7 to my Galaxy S3 using both Wifi Hotspot AND Bluetooth.
With Wifi Hotspot, my Nexus 7 shows connected and has excellent signal strength, but I cannot connect to any website or access the play store. It's like no data is going through.
The same with my bluetooth connect. It shows it's paired and connected, but no internet data.
I called Fido (my carrier and they say I have tethering enabled on my account - of course it should be enabled cause I've tethered before)
Please help me with this.
I've tethered my N7 to my Evo LTE with wifi tons of times. Are you sure the phone is actually pushing out data? Try tethering your laptop or something to it to see if it's the phone or tab.
Maybe you need to reboot.. both devices... I use mine all day long hotspot with my gs3 with no problems

I've rebooted countless times on both devices.
Are you rooted for both devices? Do you use the built-in tether option on the S3 or do you use a third party app?
I'm non-rooted for both my devices.
Does your data plan allow tethering? I'm able to tether my Nexus to my Lumia 710 but no data passes through. I need to enable the "WiFi Hotspot" feature on T-Mobiles site for an additional monthly cost.

He said in the OP he has tethering on his plan >.>
On another note... I'm on Tmobile and I tether from my G2 to both laptop and tablet, and I dont pay any extra fees
When you tether from bluetooth, pull down the notification drawer and look at the bottom.
Does it say "Bluetooth Tethered" or does it say "No Internet Connection" instead?
For me, I know even after pairing my phone and my tablet, I have to go into Settings > Wireless & Networks > More > Tethering and Portable Hotspot > and check off Bluetooth Tethering.
And after that, sometimes I have to go back to the bluetooth menu of either device and click on the other device so it actually connects.
If its working, you should see the words "Connected" below your phone in the bluetooth menu of your tablet.
And the notification drawer should say "Bluetooth Tethered"
Not sure what may be wrong with your wifi hotspot though.

I called to check and the rep says I do. But he does sound like a newbie though.
I'll call back and see if another rep (hopefully more knowledgeable) can assist me.
Thanks for all who chimed with your suggestions. I will press thanks for all of you.
I called back Fido and everything seemed normal. Tethering was enabled as it always should on my account.
What he did was push some information to the server which I guess automatically sets up my phones settings to match up with Fidos settings. Told me to power cycle for 30 seconds after we hung up. I did so, and after it started up, I heard a notification on my Nexus 7 which I knew instantly that whatever he did worked.
On my tablet I use PDAnet from the Play Market.
On my phone I use FoxFi from the Play Market.
Both Apps are free & usually do not require ROOT on either device.
1) Once both Apps are installed turn on Bluetooth on your tablet. (Find your Settings App either in your App Drawer or by pulling your Notification Bar & selecting the Settings button next to your rotation lock.)
2) Open PDAnet on the tablet.
3) Hit CONFIGURE in the main screen of PDAnet.
4) Select ANDROID (BLUETOOTH).
5) Now open FoxFi on your phone.
6) Check the box next to ACTIVATE BLUETOOTH DUN. This will turn on your Bluetooth & make your device discoverable.
7) A warning box will appear. Select YES.
8) Go back to your tablet & PDAnet.
9) Hit the option to start scanning.
10) After a few seconds your phone should appear.
11) Select the name of your phone. Mine was ADR6350.
12) On your tablet select CONNECT.
13) A warning will appear. Check the box that says I TRUST THIS APPLICATION. Then select OK.
Open your tablet's Chrome Browser & try opening a website. You should be up & running now.

Do not worry, just set yr phone hotspot security to WEP ,it should work. I faced d same problem with you in d begining. Try it!

Tmobile unofficial tethering

So I think I got free tethering to work on my MG with tmobile $30 prepaid plan by changing the APN, but not 100% sure if I got the process down correctly since I've been tinkering, rooted and still on 4.3.
Anyways, maybe you guys can give a try and see if it works. This is aimed towards t-mobile users who don't have hotspot as part of their plan or have already exhausted their monthy tethering limit.
steps:
- go to settings > More....> mobile networks > Access Point names
- add a new APN by hitting the "+" sign
- Set "Name" to what ever you'd like (e.g. Hotspot4life)
- Set "APN" to fast.t-mobile.com
- Set "APN protocol" to IPv4/IPv6 or IPv4
- Leave everything else untouched
- hit menu button then select save
- Select the APN just created.
- Active native tethering (assuming you've adjusted ID and password already to your liking)
- If it works, go back into settings and select old APN... and check if tethering has been blocked.
Note: there's no need to reboot when switching APNs.
If it doesn't work, then a file change I did beforehand while rooted made a difference or something else was a factor.

t mobile and Three use Packet Sniffing to check the file headers to detect tethering. If you tether an iOS device or an OSX device to your phone, often they will not get flagged and the tethering will work. If you use a Windows PC or other device it will be detected immediately. I mention this, as it could be a factor if you tried tethering with an ipad or something and got it to work. Messing with the APN on Three has no effect, so I'd be surprised if it works with T Mobile.
Thanks for the tip! I found that this works, but unreliably on my Moto G.
I just got a MG last week and was frustrated to find tethering would not work at all out of the box. I stumbled across your post and made the changes you recommended and it worked very well at first - for maybe15 minutes or so. Then I noticed my Chromebook lost connection and upon further diagnosis it was the Moto G that lost connection to the T-Mobile network. I tried to turn of tethering, but that didn't help and I finally had to reboot the phone to get it back on the network. I switched back to the default APN and the phone worked reliably again, but obviously not tethering. In the past couple days I've tried the new APN with your settings a few times and get similar results - it works for a while, but then the phone loses cell connectivity. I've since found that I toggling Airplane Mode on and off will restart the cell connection and tethering will also start working again, so it kind of works but not as well as it should.
I've been doing more searching regarding the fast.t-mobile.com APN and other threads seem to indicate that APN is specifically for LTE phones. Since the Moto G doesn't have an LTE chip, I wonder if that's causing the reliability problem?

PS - I think there might be a typo in your instructions and fast.t-tmobile.com should be fast.t-mobile.com - with just 1 t in the t-mobile. Thanks again!

You're right. I've fixed it. Thanks.
I rarely tether, so I haven't used it in every scenario. But when I do tether, its while tethering to my tablet, my friend's phone, or desktop/laptop WITH user agent switcher on Chrome to mask the desktop/laptop as a mobile device. After reading your post, I tethered to my laptop for an hour and did not encounter any issues. Do you lose connectivity even when the phone's signal strength is strong? Have you tried tethering to a different device (mobile)?
Thanks for the follow up. I've been trying it again today from my home where I get better cellular signal strength, but I'm getting similar results. It connects up and runs for 15-30 minutes and then starts flaking out. After rebooting both the phone and Chromebook, the Chromebook kept trying to go to a T-Mobile sign-in page, but couldn't even load that. And I too am using a Chrome extension to change the user agent to Android. The Moto G seems to be working fine and not losing it's connection this time.
I have also been able to test tethering on a Nexus 4 running Android 4.4.2 today and the Chromebook is connecting just fine and staying connected - no problems at all. I compared the APN settings between the 2 phones and the Nexus has the MMSC entry filled out (which xda won't allow me to post here because i'm too new), so I added that into the Moto G, but it did not help. Darn. I really like the Moto G, but really need reliable tethering. Thanks again...

You need install a User Agent String changer addon in your browser and change the string.
I use this one: https://chrome.google.com/webstore/...r-c/djflhoibgkdhkhhcedjiklpkjnoahfmg?hl=en-US
I have instructions for another device here: http://forum.xda-developers.com/showthread.php?t=2201062
Good luck.
Thanks for the recommendation! Sorry I didn't make it more clear in my reply above, but I am using a user agent switcher - currently the Ultimate User Agent Switcher. Just to be sure, I disabled that extension and installed the User-Agent Switcher for Chrome that you linked to, but unfortunately I'm getting the same result - the Chromebook takes forever and keeps trying to connect to the "Welcome to T-Mobile" page.
And I tried again with the Nexus 4 and the Chromebook connects up immediately and runs great - no T-Mobile page or any other problems. I did a little more research and found a post on the Nexus 4 forum recommending disabling IPV6 in the APN Protocol, so I switched both phones from IPV6/IPV4 to just IPV4 and am getting the same result on each. Both phones work fine on the cell network and Internet, but the Chromebook only tethers successfully to the Nexus 4.

You need to set the Firefox string in my thread. That is the only desktop browser string that works. The reason why Chromebook/Ipad/Ipod devices work is because T-Mobile allows those devices since they can all have Cellular radios in them for radio. It would block legit paying customers.
Hey - thanks for the quick follow up!
Unfortunately, I just tried all 3 of the Firefox settings in the user agent switcher and rebooted the Chromebook each time, but no joy - each time after restarting and connecting to the Moto G wi-fi hotspot the Chromebook just tries to redirect me to the T-Mobile site.

Do you have the T-Mobile branded Moto G? If so you may need to disable the upsell app as I did in my L9 thread. You may also need to edit /etc/apns-conf.xml
Also, use this app instead of the builtin tethering. It may be notifying the carrier of tethering.
https://code.google.com/p/android-wifi-tether/
Thanks again for more suggestions.
I am using an unlocked US GSM model of Moto G I purchased from Amazon.
I have not rooted yet, but may try that and the tethering app you linked to. I'm wondering if the stock app included on the Motorola device is the culprit, whereas the stock tethering app on the Nexus device may not be reporting back...

Mobile HotSpot on AT&T grandfathered Unlimited Plan

"Mobile HotSpot on AT&T grandfathered Unlimited Plan" If you have a regular At&t plan the hotspot is easily employed...... I have the grandfathered plan that sends me the "Call 611 to enable."
Does anyone have a way to employ the mobile hotspot on the Galaxy G935A? Seeing as there is no root, is there any coding or permission tweaks I can try to get the Hotspot to work?
FoxFi works with tethering, but turns up a 10246 permission error for Hotspot. I though I had it when I kept the system from checking my plan with At&t.....But eventually, the system picked up on the blocking I employed.
Two main reasons for me to root are Viper4Android, which there is not get-around. The second is the Mobile Hotspot. When I travel with my kids, they used to use my Rooted G3 to play Youtube, games, and interactive apps to keep them busy on long road trips.
My choices, buy a G935F on Ebay and root it.....but then I would have to sell my G935A.
Someone miraculously figures a way to root.
I find a work-around and change "permissions."
I'm leaning toward the new phone, just hate spending $700 on Ebay with electronics.......
Any help is appreciated, even the slap of reality to "just get the F" and quit screwing around with the A.....

Can someone help me try this? THERE ARE NO MODIFICATIONS HERE
-I opened the mobile Hotspot app, set it up while I was connected to my home wifi network.
It worked, but used my home network as the hotspot.
-Next, I shut my wifi off and expected the error, but the phone hotspot transferred to the 4g, as long as I didn't turn the hotspot off.
I also tried this at an open cafe wifi hotspot, then turned off the phone wifi again, the hotspot remained working as long as I didn't hit the back button.
* I did get a tetherprovision.apk error, but it didn't shut the phone mobile hotspot off.
I tried this on my wifes S6 Edge, but it didn't work. Can someone try the S7 and S7 edge G935A
***To make sure it was the phone hotspot, I checked ip addresses before and after the WIFI was turned off. Ip adress changed from where I live to a place in Maryland, so fairly sure it wasn't just a fluke, but that is why I need someone to test it........Thanks

I had the same challenge (unlimited data but no tether provisioning) and wanted to tether without giving up my awesome plan or pissing off my employer (my corporate plan includes international LTE roaming -- amazing!). Being unable to root and having unsuccessfully tried FoxFi (gave me an error message about internal connectivity or somesuch) I discovered Samsung already has an app for this called SideSync. It requires a USB cable but is able to set up its own hotspot.
I'm using a Mac laptop with SM-G930A and after installing SideSync on both the Mac and the phone, and launching both, I can detect the phone connection (apparently this works better when the app is running in the background but not on its home screen). Then I can click the "More" button on the Mac side and launch "Enable Mobile Hotspot". You'll need to give it MTP and several other access permissions the first time, but it should create and configure a WAP of the form "SIDESYNC_HOTSPOT_##:##" and connect the Mac to it. This works even if your phone provisioning wouldn't normally allow it. Easy!

I am on Win 10, I will try and find Sidesync, or an equivalent thanks! But, that is exactly what I was looking for!
If I find a Windows equivalent, I will repost.
Thanks again,.
I found it but it says both devices utilize the same wifi connection. Will it Direct Connect them and use 4g as the wifi?

I am on Win 10, I will try and find Sidesync, or an equivalent thanks! But, that is exactly what I was looking for!
If I find a Windows equivalent, I will repost.
Thanks again,.

Not sure what you mean by utilizing the same wifi connection -- It is NOT the WiFi Direct feature if that's what you mean..if the phone is connected in that mode, this will need to be turned off first. Mine handles the setup of the hotspot automatically (at least on Mac). It's a little wonky but usually works on the first try. And yes... once it's working, the phone shows that it's got a device connected via wi-fi sharing icon, and the laptop shows it's using SIDESYNC_HOTSPOT.

If figured it wasn't the Direct. It installed and loaded right up, but it disconnected on the PC side every few seconds. I think it might be my A.V. software......I'm going to mess around with it this weekend to see if that's the issue. Thanks for tips.
So sidesync is a hotspot app, must be installed on all devices that want to connect to hotspot (in this case galaxy g930a). Is this correct?

Switch back to cellular when wifi has no internet, but keep wifi connected

tl;dr: When my phone (Sony Xperia Z5 compact, Android 6) connects to a wifi with no internet, I want to use the local network on the wifi but use the internet from my mobile data. Instead what happens mobile data doesn't switch back on while connected to wifi with no internet.
I have been trying to find a solution for this since forever. My camera creates a local wifi connection which I can connect to to view the camera as well as controlling it. The downside is that while connected to this network my cellular data gets switched off, despite this wifi network not having any internet. So while using my camera I have no way to access the internet. It wasn't a huge problem up until recently when the app I use is introducing livestreaming. I really want to use it but I am unable to find any way how to keep my phone connected to this wifi network (and being able to use it), while any internet data goes over 4G. I am using android 6.0.1. I am quite sure I was able to do this on my previous phone with an older Android version but I cannot find said option (smart network switch or something?) anymore in the wifi settings. Nor any recent similar topics with people with the same question? Anyone that knows more about this?
My phone is rooted. If I need to do any system changes I can do that.
I didnt get what you were trying saying.Do you know that you cant use mobile data and wifi simultaneously unless your device is rooted.If your phone is rooted then try using "download booster"

Err, sorry, lol. I have wifi network that has no internet, just a local network. I'd like to be connected to that wifi network AND be able to use internet over my mobile data both at the same time. As it is right now, my mobile data gets disabled even when the wifi network has no internet access.
I have talked to two friends of mine about it and both say this is already possible in Android. One friend sent me a screenshot of an option he has in his wifi settings called 'Switch to mobile data' which gets enabled when the wifi network has no internet. My other friend said he doesn't have this option but claims it has been a default feature of Android since lollipop. He tested it on his phone and indeed it works as expected. Both have an unrooted phone with stock Android. So now there is me with my brand new phone and Android 6 and I can't find this option nor does it seem to do what I want by default. I'm confused.
As I mentioned, my phone is rooted so if there is a way to turn this feature on using root, I can totally do that if someone knows how.
As i said try using "Download Booster" It allows you to use wifi and mobile data at the same time just google it.

That appears to be just a download manager if I am correct? I don't need to download anything. I just want to be able to use my existing apps to use my mobile internet when I am connected to wifi (that has no internet).
This is the exactly the thing I'm after. Screenshot from my friend's phone (LG G4 with Android 6.0): (*link removed). My other friend who also has this functionality working has a Nexus 5 with Android 6.0.1.
* Forum doesn't let me post screenshots.. But basically in his wifi settings he has an option called "Switch to mobile data". The box says "Internet unavailable via connected Wi-Fi. Stay connected to Wi-Fi, but use mobile data. Data charges may apply."
Again, I have Sony Xperia Z5 compact with Android 6.0.1 and I can't find this. Have I bought the wrong phone or is it fixable? At this point I am more than happy to even take a custom rom route.
You cannot use wifi and internet at the same time as they are completely different hardware components, using different air waves, so there's no conflicts between them. Better use internet through your wifi or use bluetooth tethering.As for the "switch to mobile data option" it disconnectes you from your wifi if it has no internet and connects you to your mobile data so it doesnt lets you use your wifi and mobile data at the same time

It actually clearly mentions that it keeps connected to the wifi. He tested it and indeed he could use the local network on the wifi side and use the internet through his mobile data simultaneously. Both friends haven't rooted their phones or anything. This is just a default functionality for them. I have now tested it also on my older phones (Oneplus One and HTC One M8) and all phones can't have both connections open at the same time.
This wifi network is created by my camera by the way and I can't change much about it. The DJI drone I control does the same thing. When I am connected to the camera or drone I lose my mobile internet connection.
I don't have any other device that has access to internet here. We don't have cabled internet, only mobile internet.
Interestingly, in the developers options there is an option called "Mobile data always active" ("Always keep mobile data active, even when Wi-Fi is active"). I've tried it many times, rebooted my phone but this doesn't actually do anything. Even with this option on when wifi is connected the mobile data gets turned off.
This is beyond annoying!
I too have struggled to find a solution to this problem. I do not have a WAN connection to my home network. It is LAN only. I have four PC's, three Sonos speakers, two hdhomerun TV tuners, and various hand held devices that all use the LAN. All I want to do is be able to use my Moto X Pure to control Sonos and file sync to my LAN via wifi and simultaneously use mobile data for WAN stuff. I know the mobile connection is active with wifi enabled because I can see it when running if config, up route show etc... I am trying to learn about the routing tables to see if I can fix this myself. I love my android devices and am loyal, but this is beyond dumb! Any suggestions????
How to fix for android
okay so for anyone who doesnt know still go into the about phone option in your phone settings, then click on kernel version, build model, etc til one pops up with a flash notification saying click so many more times and youll become a dev. once you done that go into the developer menu and scroll too wifi assist or force mobile data upon wifi connection. exit out , open your app , bobs your uncle
Thank you for the answer.
I tried with my Huawei but it doesn't work. Could you tell with which phone you made it work ? Thank you !!
Ok here we go, after 12 years this my first post.
Above suggestions related with developer options nothing to do with OPs requirement. Those option only allows the device rapidly switch to mobile data when the WiFi signal gets weak. Since you always close to your DSLR camera it solves nothing because WiFi signal is always strong.
Root cause of the problem is you can not have 2 default gateways (i.e. router address) for your networks in any operating system (Actually you can but you have to set static routes, which is a pain in the ass for regular users)
iOS handles this in a very simple way. Set your wifi connection to static IP address instead of DHCP and leave your default gateway or router address blank. Viola you can have 3G/LTE data while you connected your camera and now you can sent your downloaded pictures via Whatapp while you still connected to your camera via WiFi. (In my case Panasonic Lumix)
I stumbled upon this thread via Google since I needed the same thing now with Android. But iOS way failed. Actually I am shocked that you cannot leave WiFi Gateway address blank in Androdid 8.0! Save button grays out if you leave it blank. This is really weird. At least with Galaxy S8 Duos with Android 8.0
So anybody know how to setup a WiFi network without a default gateway, please share.
Is this phone specific or something? Never had that happen, I have no problem with wifi being on without internet and using cell data.
I don't think the UI really exposes anything like it directly but you can technically have multiple gateways; it's not something your average user will understand (policy routing)..
Having said that, if you're attached to an AP you should at least see a /24 route out your wireless interface (standard dhcp lease). It's quite common for the AP to have client isolation but are you sure you're not using something like Wifi Direct or even adhoc?
Similar Experience
I have been through this experience long ago. All I did was to sell the phone and bought a new one.
