I'm running the stock 4.1.2 on a GT-N7100. Used to work fine, now trying to enable wifi hotspot tethering but I get nothing. Basically I tap the I/O button while it's green and it grays out for a bit then returns to O. It won't turn on. Any help is appreciated. Thanks!
update: even regular wifi doesn't work, stuck on trying to activate. I don't recall changing anything between today and yesterday. Tried rebooting obviously still nothing.
It worked for a while then stopped again. Is there like a reset for wifi/tethering alone?

hi guys im on the Frosty JB rom the newest update and my wifi was working fine for a while then i disabled the exchange services and my wifi started to act derpy. like it turned off then turned back on and kept doing that so then i turned it back on and it still acted derpy so i pushed *#0011# and turned wifi power saving mode off and it didnt work so i have no clue what i did so if anyone has a fix please tell me. i would really appreciate that.
So i just got the note 2 and everything was going fine. connected to wi-fi downloaded app then suddenly the wi-fi just cut out and it wouldnt turn on. everytime i tried to turn it on it would display "turning wi-fi on..." then it would switch back to off and nothing would change. I tried soft reset, factory reset and all the other possible options that the web gave. I have no idea what is wrong, everything else on the phone work except wi-fi if you have any other possible options im open to anything

In my opinion, it is because you installed an app or something that is interfering with the WiFi. It happened to me with the tethering.
Did you make a backup? If so, restore it
Wiping data and all that won't solve it
Have you tried restarting your modem?
i have a samsung galaxy note 2. i got a popup msg from att alerting me that i was exceeding my plans data limit. shortly thereafter, i noticed wifi wasnt on. i tried to toggle it on, but the button was greyed out and would not allow me to slide it to the on position. it seems to be permanently off. i have powered off the phone, taken out the battery and sim and sd card, powered it back on, still not able to select the on switch on wifi. i reset my router, still nothing. i downloaded wifi fixer, still nothing. i have been reading up on this and it seems no one knows what gives. my phone is not rooted. i have turned off wifi power saver. i have not performed a hard reset as most posts i have read said that didnt work. i'm at a loss.
bluetooth is working

I had something similar in that I would turn on wifi and it would not turn on. Tried everything you did, even the hard reset w/ no love.In my case once I turned off Bluetooth and tried to turn it back on it began exhibiting the same behavior. I was able to "fix it" by booting up in safe mode, turning on the wifi (and BT in my case), and then rebooting. It has been working since then without issues.
Hi
I got a used galaxy S3 for cheap, but wifi was not working on it. Turns out it was the antenna cable inside the phone, so I replaced that part, but it still didnt work. I downgraded the software from 4.1.1 to 4.0.4 (via ODIN), and wifi worked, so I left the phone alone for a few hours. Then I started using the phone and downloaded a few apps then all of a sudden wifi stopped working, and the phone won't connect anymore. Tried rebooting, reflashing, going to *#0011# and turned off wifi power saving mode, but still didnt work. WHen I enable wifi or bluetooth, the I/O switch gets greyed out and it just says "Turning On..." . Anyone know what the issue is? Could it be a hardware problem (wouldnt think so because it worked for a bit).
thanks!
No one has experienced this problem on their phones?

Kernel issue. WiFi drives are built into the kernel. Flash anoher stock kernel if your on stock or flash aosp kernel if not on stock

I'm experiencing similar trouble with my s3 the wifi never turns on. I've only started having this issue since I got a factory reset done because of some other trouble and now I'm sick with this new issue.
Did you find anyway to fix it yet. 923
Recently rooted s3. A few days later auto-connect for WiFi was turned off. I can't locate where or how to re-initiate. Any clues would be appreciated.

Yeah, I've done all the settings in Wi-Fi. just can't get the 'connect automatically' button to come up. tried forgetting, then re-installing wifi, clicked the 'connect automatically', but when I saved the connection, it reverted to no auto-connect. Guess I'll try reinstalling liquid smooth. Thanks for the thoughts.........anybody else having this problem?

I have never had this problem but its nothing, once you reinstall your rom/wipe dalvik/cache everything will be fine
