Hey, I've got CM10 on my GS3. When I go under Settings, the Wifi toggle is set to Off and grayed out so I can't toggle it. When I go to Wifi, it just says "Turning on Wifi" indefinitely. I also have issues with wifi tethering sometimes.
Any solutions to this? I haven't been able to find any posts on it. I'd prefer not to reset to another ROM, but if there's no other ways to fix this, oh well.
Thanks!
Flash to a TW rom and see if it works.
If it doesnt work, try the following:

So as to fix this problem,some people suggest to do a Factory reset.But, it is completely unnecessary.Instead you can try the following methods, which where tested by me successfully.
1. Dial *#*#526#*#* to reload the wifi driver.If it doesn’t work, restart your phone and dial it once gain.It will work for sure.
2.There is an app “Wifi-Fixer” from android market,which claims to be fix this problem.But seriously,it hadn’t worked for my mobile phone(Samsung Galaxy Ace).But,
if you are interested, can download and try it here.
For HTC users, I have a pretty good trick which works very well.
When you have obtaining IP address problem,
1.Turn off wifi.
2.Open “Allshare”, then you will be asked to connect to a wifi network.
3.Then select the wifi network that you need to connect from the list opened.
Magically, you will be connected without any extra effort.This works 100% sure without fail.
If that doesnt work try this:
1.Dial *#*#526#*#*.Then a message will be shown “Driver loading Successful”.
2.Now Start the WiFi, it should work.
If the message “Driver Loading Unsuccessful” is shown, follow these steps:
1. Dial *#*#526#*#* again and click options button on your phone.
2. Select Rx test.
3. Select Channel >9 .
4. Click Start and exit.
5 . After some time, turn on the wifi.It should work.

My phone won't even let me dial that, the code disappears the second I hit star the last time, not sure if it's supposed to do that. I'm gonna just try updating CM and see if that fixes it.
I was able to install CM11. Flashed cm11 on 12/7 and everything has been working great. I was able to update everything. On next morning, wifi signal was there but no access to internet. Wifi is on but it picks up no wifi signals. If I turn on/ off wifi doesn't find anything else. And receive WPS has failed error... if I click in refresh.
I have already daily upgrade nightly builds to up to date build (20131217), but success. same issue. Any idea?
If I do a full wipe and then restore a backup it work for a day, then stops again.
I have the same problem. I dropped the phone on the wooden floor, and thought the wifi just broke, but now I'm confident it's because of bugs in cm11
Considering returning to cm10.3

Installed BeanStalk with no data/cache wipe and WiFi is still not working.

I updated mine to 1/14/2014 CM11 Nightly and still no Wifi. Anyone have the same experience?
I had the same problem. You can try wiping all data, reinstalling ROM and gapps. Everything but the camcorder works!

I just upgraded to cm 11 build .17 and Wifi just doesnt turn on.
It says turning on... and just hangs.
I've set region to Europe to no avail..
I found a solution. Download SQlite debugger from Play Store. Open the app, then open Setting Storage, then setttings.db, then Global, then scroll down to wifi_display_on and edit the value, change it to 0. Reboot and then you should have wifi working again.

The value only reverted the one time, hasn't been an issue again.

This totally worked for me. But it stops, and the problem is back again. Checking the settings.db shows it has returned to 0. (wtf!)
Not sure what to do at this point. It's nice to know it's not hardware.
thanks!
i had the same problem. this guide solved my problem. thanks.
Fixed my network problem by removing ad-hoc network
Hey,
I had a problem when I tried to connect to an ad-hoc network I'd setup. The network settings screen would freeze up on me and then..... nothing. I checked the database settings by adb'ing onto my phone (a rooted oppo find 5 by the way). I checked the values of the settings database as described by others. That didn't work so then went to the file containing connection details of known wifi networks
Code:
sudo ./adb shell
[email protected]:/ $ su
1|[email protected]:/ # cd /data/misc/
[email protected]:/data/misc/wifi # ll
First I start a shell on my phone (sudo ./adb shell), then I change from a regular user into the superuser (su) then I go to the directory containing the wifi connection info.
There I opened the file wpa_supplicant.conf and removed the ad-hoc connection that caused my problems. I've also read about people simply removing the file. Downside of that is that you will loose your painstakingly acquired history of known passwords (but I guess in the end that is still better then not having a wifi connection at all....)
Hope this helps somebody
Cheers!
Hi

May I ask for a absolute path of "settngs.db" file, please? By the way, have you fixed the issue with reverting?
Thank you.

Hi guys,
Just wanted to tell you that setting wifi_display_on to 0 didn't work for me. Full reset did the trick on my GS4 GT-i9505

Thanks so much dude! I was so close to resetting my phone and this worked perfectly! To those of you who got lost on this I'll try to describe it better... Download SQlite debugger from Play Store or on your PC then transfer the apk to your phone and install Open the app, then press 'App' and scroll down to 'Setting Storage', then 'setttings.db', then 'global', then 'name', now scroll down to 'wifi_display_on' and edit the value to 0, make sure you commit this change by pressing the arrow icon in the top right and accepting. Now reboot and turn on your WIFI!

So here is how it all started. One day i woke up and my phone was continuously restarting and just got stuck on wifi turning on. This is a very common problem and is said to be a hardware issue. A common fix to this, is to open the device and put a couple pieces of paper on the wifi chip to press it against the motherboard. This fixes the problem for most. So this is what i did. But for me, now it identified all the networks in the area but when i connect to a network, it just says "saved"or sometimes "wifi connection failure". The restarting issue is completely gone. I have tried factory reset but no luck. I was unable to find people with similar issue so any help would be highly appreciated!!
I am using android 6.0
previously before adding the papers, the mac address also changed to 02:00:00:00:00:00 but now its back to normal.. but not connecting to wifi.. It just says "connecting" and then "saved".
Please anyone? I am still unable to solve this issue!! ::crying:
BUMP!
Same Issue
Did you find a fix? Im still facing the same issue.
I got the same issue but only with one router. I believe there is something with the router not G3 itself.

This problem arrises due to installing custom rom and restoring qcn and it could not be solved by restoring back to stock etc.
Simple solution to that problem is
First you need to install any Marshmallow firmware custom rom fulmics etc.
Then go to hidden menu
1- on dial pad : *#546368#*850# (850 is for D850 and write for your model )
2- find and click SCV Menu it should be 3rd one
3-click on CRCWIZARD Test
4-click the tab Auto MID
5- uncheck IMEI in MID settings
6- click generate to generate your new MAC's
7- click MID write
8-Click Refresh to be sure that you changed MAC adress
9-Rebbot phone to take effect!
After reboot you will be able to connect any wifi without having wifi saved problem or connection failure

I have a problem with one of my Mi6 phones: it completely losing a signal while working in 2G network.
The problem looks very similar to USA band problem in Mi5. May be reseller flashed or enabled somethin like this mode on this phone.
The problem is I can't fix it at all. I tried to erase and flash different modems, tried different ROMS both MIUI and AOSP based - no effect, still no network in 2G.
I found a method to fix bands using Qualcomm Drivers and QPST tools, but I faced a problem that Mi6 declines to enter diagnostic mode either using *#*#717717#*#*, tried adb shell commands and, finally, tried fastboot edl reboot option. All of them doesn't work at all. ADB Shell - just nothong happens, Fastboot - usual reboot of the phone, *#*#717717#*#* - "Open diag failed!".
Does anyone face same problem? May be there're some more soltions or I doin anything wrong?

i experience similar problem. although phone shows signal in 2G, call is either not possible or very poor quality. only answer i got that it's a service provider issue, but the same SIM cards work in Oneplus 3T, HTC One M7 and different kinds of iPhone.
I suppose it's a modem failure, but i haven't found a way to diagnose it more deeply without voiding the warranty.
Maybe you have any success what is the problem exactly? and, maybe, how to solve it
Hello, I have a rather strange problem with my phone.
After the Update which has just been released (MIUI Global 10.3.1.0 (ODEMIXM)
he began to behave in a strange way my mobile internet.
For example: Youtube, Facebook, Messenger, Google Maps work normally.
And all other applications no longer (even an application to Check system update)
I'm popping up a message: No connection.
I did different things: Reset Internet settings,
change network settings in options (* # * # 4636 # * # *)
and even a hard reset.
if you have questions Yes on Wi-Fi works normally.
Greetings!
Try factory reset first.
mine has similar problems after a call. Some Internet stuff still works, most don't, unless I disable and re-enable mobile internet from the dropdown menu. Did you find a solution, MrKaim?
Same problem in my phone too. The only app which is remain usable of the internet is the Chrome browser. Messeaging apps, navigation, ebay, etc... is always lost somehow the connection: even when I using the app: for example I browsing in the ebay app and after 10mins,its says sonetging got wrong and I can go on only when I turn wifi/adata off and on. And yes, ön my mi mix 2, the problem is still exist on wifi and mobil net too.
Mi Mix 2 Havoc OS 3.7 Mobile Internet
I am facing a similar issue.
Has anyone found a solution for this ?
I'm running a ROM : Havoc OS 3.7 Android 10
Also tried ROM : AICP and Lineage.. Same Issue!
I keep shuffling LTE / 3G it connects sometime but the connection is unstable.
Permanently displays an X in the mobile signal as if there is no mobile data connection.
Please share a solution if anyone has found one.
I realize only some data isn't working but you could save your apns-conf.xml from another setup where you have no data issues and everything works perfect (I always keep one handy) and delete your current apns-conf.xml in /system/etc and system/product/etc and paste the good one in your /system/etc and set permissions on new apns-conf.xml to 0644 using root explorer or whatever root file manager you use then go to settings on your device/networks and internet/mobile network/access point names/ and top right hit the three dot menu select reset to default and wait till you see LTE show in status bar and reboot. If it's an apn issue that will solve it.
My Mix 2 isn't hooked up anymore to a service but I do use it on wifi at home but the apns-conf.xml on stock rom/miui may be slightly different than they are on an AOSP custom rom. I know that's been the case for me on every device I've done this on so be sure if you do give this a shot that you use your miui apns-conf.xml on miui roms and AOSP apn xml on AOSP custom roms so that it will work.
I've been using this process when I have had any data issues at all on my last 3 devices and it's worked 100% every single time when after installing a custom rom I've had no data this works to get LTE going. Credit to spaceminer for this info on the apn delete and swap, data fix as he's who I first learned this from on another forum.
