wifi suddenly will not turn on

Well suddenly wiring will not enable on my nexus. Everything else works, I cleared userdata davlik and cache reinstalled my rom and still no go. So I flashed cm9 thinking it was a rom issue but it still will not enable. Any ideas?

Anybody..?

connect device to pc, 'adb logcat >> logcat-1.txt', enable wireless. paste it here so people might try to help you.

Try flashing a custom kernel like franco or fugumod.

I did that didn't fix it. I just put it all back to stock and locked the bootloader. Guess ill send it back...

yeah, i would do that, if reflashing stock doesn't solve it. if it still happens, lock your bootloader and turn it in.
sorry we couldn't be of more assistance.

Yeah I've reflashed stock and locked boot loader hopefully Negri will rma it for me.

[Q]G2 Wifi issue persists through unroot, ota updates, downgrade, re-root, wipe, etc.

As the thread says, I have a wi-fi problem that seems to persist no matter what I do. I was running g2 slim, and whenever I turned on wi-fi, the phone would go into a restart loop until I turned wi-fi off. When I unrooted, stock froyo also failed to connect, but instead of restarting it just said "failed to search for networks". OTA Gingerbread acted the same as G2Slim, unsurprisingly. Downgrade, re-root, superwipe, and reinstall G2Slim, same problem.
The problem seems to be dependent on a particular access point, I'm guessing someone else's router in my apt. complex. At school I can connect to wi-fi no problem. At home I cannot, even if I use a different router.
In the logcat I see various errors associated with wi-fi, but I am not sure what is significant and what is not. Is there a particular filter I should run with logcat to make troubleshooting wi-fi easier?
Would it be worth to mess around with installing different radios to see if that fixes the problem?

If I'm understanding the output of logcat correct, here is the log from enabling wifi to the fatal exception:

Tried a handful of radios with G2 Slim, including stock froyo radios, all cause restart loop.

Unfortunately, most likely thing is a HW level issue...
It could be Wifi Calling screwing with things though. Have you tried using wifi without any wifi calling apk or libs?

Alright, well at least I can stop chasing it now.
The unroot procedure I used took me down to pre-OTA Froyo, which doesn't have wifi calling, and it still wouldn't search for networks.

Anyone able to fix this issue?
It happened after CM 7.2 stable upgrade.
here is what I have tried so far:
1. reset permissions on conf file (and made wifi owner)
2. tried wpa_supplicant starting from shell. Gave error that:

So... is there any way to fix this or can i just throw it out of the window and simply buy a more reliable tablet (Asus' Nexus 7 comes to mind right now...)?

Wifi quit working any solutions

So my wifi was working fine monday after noon.....come home that night and it will not turn on. The only thing i though could be the culprit was the kernel i just flashed. I installed a known working kernel and it still would not come on. Did odin to stock still same result. Searched for hours for a solution and could only find a few posts of the same type of issues on various forums. So was wondering was this ever found to be a known issue or is a occasional defect............below is my logcat for the wifi, which i get no matter what rom or kernel im on.

See http://code.google.com/p/android/issues/detail?id=28036. The only partial workaround I've found is rooting, installing https://play.google.com/store/apps/details?id=com.fardjad.android.wifixmanager and rebooting/power cycling only when the wifi has been turned off successfully.

Hey,
I've destroyed my HOX years ago (WiFi won't turn on, Mobile network won't work) and i'm looking for a nandroid backup or a way to get my wifi back online
Does anyone know what i can do?
