save your apps(only apps and config of the apps no system data) with titanium backup, store the titanium backup folder on your pc
make a hard reset and flash the newest firmeware, after that copy tb folder back on your phone and restore the apps.
have fun

Just a guess, check this if problem is: '' wifi stuck on obtaining IP address from".
for me, problem was on my home router and work router was ok, the thing which worked and still working for me(I found it somewhere here only), is go to AllShare app on your device and then it will ask you to connect wifi and there you go it will connect wifi right away.
I use this trick every now and then, funny thing is problem does not occur if my home router is continually running, if I turn off router before leaving for office and in the phone stuck again and AllShare trick works all the time.
try it, may it works for you too.

Great tips, I will try this later and let you know is this works...

Thanks. Awesome tip. Have been fighting with this problem so long. Works like a charm

fine, that the tipp help you

Awesome, now everything works as a charm. Thanks a lot!!!

I agree. Great tip. Used it for a while until I flashed 2.2.1 firmware. Now all my wifi problems have disappeared.

wifi problem fixed in 2.2.1
Seems, problem has been fixed in 2.2.1 release, for those who is yet to get 2.2.1 (not talking about flashers) can go for 'AllShare' solution.

hey guys im having a wifi problem as well but it seems its kind of different from the rest of you...
my wifi is connecting fine to my router... it runs fine for the first say maybe 5 mins... and then it just stops working even tho it still connected to the router... it just says no data connection... this was happening on my 2.2 froyo then i flashed it with darkys rom 9.2 and im still having the same problem... i need to reboot my phone then only the internet works again for 5 mins then stops again unless i reboot.... its verrryyy irritating i tell you...
tried the allshare but that didnt really make a diff cuz the router is connecting... im just notgetting any internet after a few mins....
any advice would be great..

unable to scan wifi networks; auto turn off of wifi
my problem is similar. i am able to turn on wifi but it won't scan networks ("unable to scan networks"). it then turn off the wifi after a few seconds by itself.
any help?
i've done several reboots and the allshare solution, the prob persists. will do an upgrade to gingerbread and will see if it solves the problem.

I've upgraded to gingerbread and wifi issues have been solved sunbed then.

Bluetooth and Nexus4 issues and observation

Ok so i got my Nexus 4 yesterday and of course BT (Motorola Elite Silver) connects and then within 3/4 seconds will disconnect and it does this continuously. I really need BT to work. I have flashed cm10.1-rc4, night-lies and other roms as well and the same problem persists. I went to three, thats right three T-Mobile stores today and tested the same BT on their phone and it worked flawlessly. One of the Nexus 4 had Android 4.2 (JOP40C) and base-band .33 while the other two had 4.2.2 and base-band .48. Wifi was ON on all these devices and i did not notice and issue with them. My BT stayed connected for over 5mins and i even turn it on/off as well as the BT toggle on the phone and every time it worked without disconnecting or exhibiting any issue. I should also mention that i have flashed base-band .33 and the problem still exists. Does anyone know where i can download a dump of the Nexus 4 for t-mobile?
Is it possible that i have a faulty hardware?
Is there a way to unload the BT stack and reload it to test?
I did discover that when i connect the phone to my computer and the "usb debugging connect" message shows up, the BT/WIFI does not disconnect and works as normal. Now if i disconnect the cable it starts acting up again. Maybe a dev here will be able to figure it out now but that is the behavior i have noticed all through out my testing.
PS: i also have a BlueAnt Q2 and it does connect and sometimes disconnects. WIFI when the BlueAnt Q2 is connected becomes really unstable and disconnects.

Are you undervolting? Any custom kernels? If not, try flashing one. Does it work fine with WiFi off?

No, i am not undervolting. I have tried CM10.1 nightlies and RC4. Even with WIFI off the problem still continues. I am trying to download google 4.2.1 and see if it still a problem.

I use a Bluetooth headset too, and from what I know, in many ROMs, Bluetooth does not work well with WiFi. If both is on, my WiFi will definitely lose connectivity, and/or my Bluetooth will lose connectivity. Either way, they just cannot coexist together.
Turning off my Wi-Fi is the only way I can get my Bluetooth to work.

I think our units are defective. I already called Google and they are sending NEW replacement out to me asap. I don't get how the t-mobile store once worked. The weird part about mine is if the phone is connected to my PC, it works fine. I just can't figure it out.
Tested another one today and it worked flawlessly.

[Q] Need Help (i9505 Wi-Fi, BT, GPS, NFC) Not working

I ran out of solutions to fix my phone. I've flashed every firmware, data reset, with custom and original recovery and still no wifi or bt. flashed both modems but nothing. bt scans but when it finds something the button goes grey. wifi only turns on if bt is on. i dont have a lock on my gps unless i use gpsfix. nfc connects but wont transfer files. any suggestions please!!

You may be facing a hardware problem. I think you should go to a service centre for this. Sorry, but there doesn't seem to be any software solutions as you've been quite thorough with trying to fix it by software.

Le Pro Bluetooth Issue?

Recently noticing the Bluetooth
Doesn't turn on from the quick settings
Or the Bluetooth Settings.
Anyone else experience this?
Any known fixes or advice?

No problem here, and I have been using it almost every day for about a month

yah, no problem here either. I guess you already tried rebooting the device....

I have had issues like that with BT, reboot resolved the issue. Seems like the software on this phone is not good at handling sustained connections, WiFi or Bluetooth. I see wifi also being disconnected and re-connected quite often.

My X727 shipped with 18s and got the two OTAs to 20s recently. Never had any problems with Wifi or BT connections - music streaming in car and phone calls. Might depend on how your AP environment is set up since I've never noticed issues with sustained connections.
Sometimes I would notice the cellular data connection drop out and require restart, but nothing with Wifi or BT.

Thank you everyone for your input..
A reboot usually fixes this..
But really shouldn't have to resort to that every time

I've had issues with the BT when going from my car to BT headphones, where it will connect for phone audio but not media audio. Turning BT of then back on again "fixes" it, but it's a minor hassle. When I first updated to 20s, BT wouldn't turn on, but a reboot corrected that and I hadn't had any issues with toggling BT on and off since.

This happened once, reboot solved the issue. I used to use bluetooth a lot, but rarely now as my current car HU doesn't have BT. Didn't have any problems when I used it a lot.

I've had the same issue for the past couple weeks. It only seems to have this issue with the cars BT. It may be a minor annoyance, but it can cause some big issues seeing as how messing with your phone can get you pulled over now.

I have this issue. I use Bluetooth in my cars and Android wear. I never notice an issue in the car. But sometimes I'll notice on my android wear watch that's it's disconnected from the phone. I'll check the phone and Bluetooth is off and won't turn on. A reboot usually fixes it. Odd.

Same issue here

This seemed to go away for me when I turned off all of the aggressive memory management features.

The updates seem to have fixed this though..
I can't turn on Bluetooth from the quick access menu or even if its on.. its doesn't show on the quick access menu..
Anyone notice that lately?

Seems to be not working even if you turn off and try to turn on from the quick access menu. I am on 21s.

The following fixed it for me:
Dial *#*#46360000#*#* and uncheck 'Enable background resource control'.​
Reboot

Scanning Settings
I think y'all should try disabling Bluetooth Scanning in Location Settings. It is a problem in the stock ROM as well as LineageOS ROM(which I am currently using).
Just try disabling Bluetooth Scanning in Location Settings (three dot menu)..... I'm sure it'll help.

Those posts were made over a year ago. They figured it out already.

It's 2018 and I have the same issue. What do I do?:crying:

Weirdest issue Data & Wifi connection but no internet???

Hi, I have got a very strange issue, I have data and wifi connected but cannot connect to the internet with either, if it was just one or the other but with both data and wifi, I have tried many 'fixes' but nothing works, I restart the phone and both work fine for a while but after I wake the phone from standby neither work again... maybe this is a clue any ideas? thanks

What does not work? Is there only a particular app that doesn't work over either one of them?
Did you ever use a VPN for this phone?
Also, do a factory reset and see if getting back to the original settings it will work.
