[Q] WiFi won't turn on - G Tablet Q&A, Help & Troubleshooting

Hi All,
So I just got my new viewsonic gTab and put VEGAn GingerEdition on it. It worked great all of yesterday, but today when I turn on my tablet, my wifi will not turn on. If I go through settings and then tap the Wi Fi label to turn it on, it says "Turning on...", then about 10 seconds later it just says Error.
So I figured it was probably due to it being a new release on the ROM and I used NVFlash to go back to stock. Same problem.
So now I am wondering if I am boned and need to return the tablet or if this is something somebody has seen before and knows how to fix.
BTW, i have found little to no information on this issue via google....
Anyway, i am back on stock ROM, repartitioned the sd, cleared every cache, and still no wifi.
Anybody have any ideas?

[Q] data wont turn back on after shutting off WIFI unless reboot phone

Data wont turn back on after shutting off WIFI sometimes unless rebooting phone. I have Cyanogenmod-7.1.0-Fscinate on my phone was wondering if anyone is having the same thing. Or is there a bug out there that needs fixed. I have tried turning it on Plane mod and off to see if that would turn it back on. And i also tired turn DATA enabled off and turned it back on but nothing had to reboot the and then it work any help please.
This has been a problem for some on mtd roms...I have never had much trouble witht it tho. My only advice is to never leave both wifi and data on at the same time...
Thanks I was just wondering I new to this but im catching on pretty fast and I love this site lot of information.
FWIW, this issue is fixed on RickS' 12.2 MIUI build. Not sure if his fix could also be applied to CM7? Maybe one of the CM maintainers/kangers could get with Rick about it to see how he fixed it.

[Q] Wifi stuck turning on. Cannot connect

Before the recent update my wifi will not turn on or off. The switch in settings is greyed out and it constantly says "wifi turning on". The switch in the quick settings panel is also greyed out. Tried re booting several times but the prime boots up already saying wifi turning on. I did do the wpa supplicant mod and it worked perfectly for 5 days. All of a sudden, nothing. I switched back to the original supplicant file. I also updated to .13. And it is still saying wifi turning on. I am Bluetooth tethered right now and it is the only way for me to connect online. Does anybody have suggestions on what might be my problem?
Edit: Also tried switching in and out of airplane mode, switching wifi on/off in power settings widget.
Did you try a hard reset by holding down the bottom volume button while holding down the power button. Keep the buttons down until you read further instructions in the top left corner. This will wipe out every thing so back it up first.
I ended up doing the factory reset through the settings menu and when i booted up the same thing happened WiFi would stay turning on. Used it to set my homescreen up for ten minutes and wifi was still not working. I let it be for a while. I woke it up and it showed wifi connections. Very strange. Much relief after not having wifi for 5 days. Ad hoc networks are showing up as well. Not sure why because I switched back to my original wpa supplicant.
I had the exact same issue :O mine happened when i was connection to a wireless acces point, whilst connecting, my tab rebooted.
After the reboot, i wasn't able to connect or do anything and just like yours, the wifi option was grayed out. And said 'connecting'.
Tried everything.... in the end the only thing which helped was a factory reset :/
odd i'm having the same problem now wifi was always grayed out tried to fix it wound up doing a factory reset but now i'm stuck with the wifi turning on problem. Tried doing another factory reset, restarting switching airplane mode on and off nothing has worked. not really sure what i can do besides waiting to see if it starts to work like yours did. Anyone else seeing this problem and if so how did you solve the problem.
WiFi Stuck Turning On
The WiFi was working just fine and then I had one of the many random reboots-- now no matter how many reboots and airplane mode toggles nothing. I should add I have a BCOKAS series Transformer. Sounds like another factory reset (done that a few of those already with this unit) won't do any good. Really getting tired of this...
Possible Solution
I may have found a solution to the problem of Wifi being stuck turning on. Now i can not promis that this will work for you or that it won't make it worse but i was stuck with the wifi continually "turning on" and no number of cold boots, factory resets, or airplane mode toggles was fixing it. I was just about ready to get a new RMA when i saw this thread and thought i would give it a shot. http://forum.xda-developers.com/showthread.php?t=1492887
The first thing i did was go to ASUS support download page and got the current version of my tablets OS (at the time it was the .14 version) I unzipped the file and placed the blob file in the "SDCard" folder on the internal storage.
I then followed the instructions on this tread http://forum.xda-developers.com/showthread.php?t=1492887 of how to intall a different version of the OS on your tablet. Make sure to have the tablet on and USB debugging mode on. Load up adb shell and use the code provided in the thread to update the tablet using the file located on internal storage
It's
su
dd if=/sdcard/blob of=/dev/block/mmcblk0p4
This will take a while but when its finished mine returned numbers different then the ones listed on the thread i'm sorry but i was unable to copy them down at the time. I took the chance and rebooted the tablet anyways. (My thought was i was missing some files that would normally be there so the number return was different then say someone just downgrading with all the working file there but i honestly don't know for sure.)
The tablet shutdown fine and rebooted showing the ASUS progress bar this also took several minutes before it finished. Once the tablet finished booting up the wifi was on and i was able to connect to my network with no problems. I was then promptly able to update my tablet to the new version .15 so this will not remove your ability to get updates. This process did not erase anything on my tablet. I had recently done a factory reset so there wasn't many changes i had made, i only installed titanium backup to restore some apps, but when the process was finished all the apps that i had installed remained. Again i can't say if this will be the case every time.
This problem has been driving me nuts for days now making my tablet a nice paper weight, i hope this solution helps to solve this problem for others. Let me know if there are any questions and i will try to be more clear in what i did.
wpa_supplicant
Changing permissions for /system/bin/wpa_supplicant by using chmod 777 /system/bin/wpa_supplicant and then turning on wifi from settings seemed to work for me, but might not work for others. Please try. (at least there's no need for hard reset)

wifi won't turn on

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.

[Q] Stock Android 4.3 - WiFi will not turn on problem

Hey folks, Merry Xmas and all that jazz,
I've a problem with my stock Galaxy S4 in that since a firmware update (4.2.2.2 to 4.3) I cannot for the life of me get the WiFi to turn on.
I've been reading a lot of forums, and it seems many have this issue, yet I can't seem to locate any solid answers. In fact it leaves me with many more questions.
I've been having this problem for almost a week even though the update occurred quite sometime before that. I've tried puling the battery but it didn't have any effect. Tried putting the phone into Recovery Mode, sadly I can't even get that to work (Vol. up, Home and Power together). All that happens is the tiny tiny blue text of "Recovery Mode" appears, vanishes upon button release, then the phone proceeds to boot normally. No recovery mode at all. Eventually I decided to to a Factory Reset in the vain hope it would reslove the problem. Answer: No. All I've succeeded in doing is losing all my data (yes it was backed up but to restore the backup I need to have WiFi turned on!)
Anyone out there know of a solution to this problem?
Just to mention, this is a stock Galaxy S4, non-rooted, on the Vodafone network in the UK.
Help?
Frustrations abound, any help will be greatly appreciated.
Cheers,
Nicowab.
N.B After downloading Kies3 I've been able to update with latest firmware.....and I can now turn on my WiFi!! WOOP!! About bloody time too!
N.B.2 Scrub that last comment. After being able to turn Wifi on and scan for signal, it allowed me to enter the password for my home WiFi then I restarted the device only to find that again the Wifi option on the phone will not turn on. Very very frustrating. Anyone got any ideas?
i have same problem on note 3 n9005

[Q] No wifi

Hey guys
The wifi on my galaxy s3 just randomly stopped working. I was sick for a week and just left it in the car, and when i got it out, it kept turning it self off and wouldn't connect to the wifi. Instead of just not being able to connect, it cannot scan for wifi availability. It just turns off. Everything else works fine. I've restared and completly cleared the phone. I have no idea what is wrong with it, nor how to fix it. Any ideas or suggestions???
Flash full stock firmware and factory reset, if still the same then it's a hardware fault.
