So I noticed the other day that my wifi will not turn on. When I go to settings and tap the slider it says "Turning on..." but never does. I've been running DIET ICS 7.20.12 and recently 7.22.12. Just tried a complete wipe and re-install and it still won't turn on during the initial phone setup. I think I'll try flashing back to the stock rom and maybe see if that works? Or is it even rom related.

After recently returning from China from an one month vacation, my GS2's wifi stopped turning on. If I try to turn it on in the notification bar, it would go hollow green for a few seconds before returning back to off. If I turn it on in settings, the same happens.
I've read over the forums and tried a number of methods such as reflashing the same rom, flashing back to the stock rom, factory reset or flashing a new kernel. All methods did not solve my problem.
My 3G works but I don't understand why my Wifi won't even turn on. I am also unable to turn on Portable WiFi hotspot as it would say error when I turn it on.
Please HELP!!!
I am currently on Android Revolution HD 4.0. I wanted to update my phone to ARHD 5.1. I was told that it is not necessary to flash the firmware so i just ignored flashing the firmware and updated to 5.1. After i rebooted the device the phoen was stuck on the htc one x screen and would not move for more than 10mins. so i restored all my 4.0 data and boot. After restoring the data i was back on my phone working and realized that airplance mode was on so i went to turn it off. on the screen showing the airplane mode wifi and etc. the airplane mode button is stuck on off with the status turning off. and the wifi on on with turning on status. If anyone know how to fix this i would really appreciate it. I am planning on flashing 4.0 again just so the phone works.
this is pretty much how it looks no matter how long i keep it on that screen or do anything it is stuck like that. i can not call or use wifi.
So I know this topic has a few posts many a year or so old but I'm looking for a possible work around for this issue. Here's a background of what happened:
I have a rooted note 4 originally running cm12, I wanted to return to a stock build and when I did something happened (can't remember what) and my wifi stopped working it would click on them immediately off my first thought was kernel so I flashed a new one but didn't help I tried a different stock build 5.0.1 instead of 5.1.1 but still same issue. I went back to the cm12 and that seemed to work fine still, I looked for another stock build because I'm stubborn and flashed a different kernel than the previous ones I've tried. This seemed to fix my wifi issue at least for a day then back to the same issues. Anyway here's what I've been messing with to try and figure this out.
I'm focused around the file wpa_supplicant.conf as I've tried restarts and all that but that won't do anything. What I have noticed recently is when I don't have any networks saved in that file I can toggle airplane mode and try toggling wifi, after a few sometimes dozen attempts it comes on and works fine so long as it stays on. If I turn it off I have to restart my process of going into wpa_supplicant.conf>deleting my saved network>toggling airplane>then spamming wifi. As I'm able to repeat this it leads me to believe it's not hardware related, slim chance on loose cable, But if there's a way to prevent the system from auto saving a password that might help with a workaround. I've tried changing that files permissions as well as the ones in the system>etc>wifi folder but they get changed back
Anyway I'm still working on finding the root cause but will update if I find anything also tried deleting the wpa file and that works to after a restart but issue comes back and so does file which doesn't seem to me that its a corruption issue
Update:
So I somehow crashed my Samsung messenger app switch to hangouts and then back so decided to wipe my phone and refresh the OS. I factory reset then advanced wiped cache, dalvik, system and data. When it rebooted I tested the WiFi in the system setup and it worked fine I could turn it on and then off normally so I decided to continue setup once fully setup and no other apps installed I retested the WiFi. It worked fine I connected to an access point and it stayed connected I then forgot the network cycled wifi and tried again and again still worked so I let it sit and would test it throughout the day. About an hour or so later the problem reappeared which was odd. I did my old workaround deleting wpa_supplicant.conf and toggling wifi until it turns on. I got it to turn on and connect to my home WiFi and left it, so far I've kept my wifi on and it's stayed active for 24hours now and reconnects fine to my home router when I'm in range and back to lte when I'm away so right now it seems I can have wifi if I don't toggle it off. Still not sure what's causing this issue as since I'm currently using wifi to write this I don't see it as a hardware issue. After trying multiple kernels I don't see that as the cause either, although possible. Will keep messing around and update if I find anything further
Update 2: so far I've been able to keep my wifi working great as long as I keep it on and don't toggle it off. Doing this has kept it active and auto connecting to my home wifi for a week straight. I make sure to keep wifi I during sleep so it won't disconnect but it also seems to stay active through restarts which is great. This still leads me to believe it's software related and not hardware but not sure where the issue is.
Update 3:
So far I've just kept my wifi on while trying to find the issue. The only other issue I've come across was since my wifi is on 24/7 and auto connects if I want to use my lte instead i have to either turn off wifi or forget my home network which neither is an option. But I have found a solution:
I was able to add a shortcut to my home screen that actually disables the current wifi connection without disabling wifi and forgetting the password. To do this you must have Tasker just create a new task in second tab, I named mine disconnect wifi, click the plus sign and select "net", next select "wifi net" there is an option that says disconnect. Have that selected then go back and thats it,add in icon on bottom right to use as a shortcut. I've tested this and it works great one tap and it disconnects the wifi but keeps wifi turned on and if I want to re connect just go into WiFi settings and choose the one to connect to
Ok so to start off im gonna give you some information: my phone was rooted with magisk and it was running b360, it worked just fine until one day my wifi kept turning it's self off for no reason.That kept happening but not very often so i didn't mind it. Today my wifi wouldn't start at all(the switch thingy went blue then gray immediately) again and if i tried to turn it on again my phone would reboot.I then unrooted and went into safe mode to see if it would fix the issue but it was the same, so i tried recovering my data from twrp. That didn't fix anything once again, so i did a factory reset(that prolly screwed me over big time) after the factory reset i realized that my phone wouldn't finish the setup thing because it needs to connect to the internet to check for new updates. So my issues are that i can't seem to be able to access my phone through adb since when i use "adb devices" it doesn't show my device, and that my phone is basically unusable right now since it wont get past the "checking for updates" phase. So what should i do? Any help is appreciated!
*update*
I got past the "checking for updates" phase and i completed the setup by sheer luck(my wifi worked for a couple of seconds), but the problem still persists. My wifi can't be turned on, or when it turns on it stays like that only for a couple of seconds and then goes off again also my phone crashes from time to time aswell(usually when i mess with the wifi, but sometimes it just does it on it's own).
I know is abvious, but is WiFi+ turned on? That can turn off your WiFi for you if not near a saved hotspot. Could be a confusion between this and location services.

WiFi+ is turned off. From what I've observed so far after i restart the phone i can use the WiFi for about an hour or two, after that it stops turning on. But if i use it for about 20-30 mins, turn it off, and turn it on again after a while when i want to use it again, it works (obv if i use it for 1-2 hours the problem will occur again). So what I've been doing so far is just use it for about half an hour then turn it off until i need it, and repeat. I know that im probably not making much sense right now but i don't know what to do anymore.
Tried doing a factory reset and wiping cache from recovery. Tablet functions perfectly fine after reset except for any attempt to turn on wifi or bluetooth just leaves it spinning still it goes back to off. On the settings screen it just has disabled under both.

I am having the exact same problem but without the reset. One day WiFi and bluetooth just turned off without any changes to the software. I just couldn't turn the Nexus on after a couple of days on the charger, screen was black. I switched it on by long pressing the power button, it booted and there was no more WiFi or bluetooth.
I tried different ROMS (Slim, Lineage) and also went back to stock with factory image, still cannot turn on WiFi or bluetooth.
Did you find a solution or is it a hardware fault?
Best, Bernhard

I'd reflash the ROM. Usually, this happens if the kernel doesn't match the ROM or if you dirty flash ROMs
