did you upgraded from stock 4.1 to stock 4.2
chech your router if it's working fine or not
run a wlan test on your tab
also wipe cache in cwm
good luck:good::good:

If you were upgrading from 4.1 it's strange, but do what @up wrote. If it won't help reflash ROM

The problem is that is never turned on the wifi! I've changed the android version of the 4.1, 4.0 and nothing still does not activate the wifi. We also perform the factory reset and still not start the wifi??? someone will have a solution? I tried to figure out wpa_supplicant sovereign but do not know much

[Q] Cannot enable WiFi on TF101

Odd thing happened today. I was testing out the EOS cornerstone new rom and was having issues with WiFi so I restored my Stock ICS setup but now I can not enable the WiFi.
The WiFi icon is greyed out on the settings tab and I can not swipe the WiFi to on in the settings app.
Has anyone seen this before? Did the WiFi die?
Just flash the ROM you were using again without any wipe. (Flash the ROM that your backup is base upon)
It seems the backup has the HC version of the wifi. I flashed the other rom again and the wifi is working fine.
Thanks.

Just flash Revolver ROM again, no wipe needed
I installed the AOSP test build of ICS, now I too am having wifi issues. I saw the ROM had it listed that there was a bug with the wifi so I didn't think much of it at first. I then installed Android Revolution but now the wifi still doesn't work.
I accidentally deleted my backup ROM..
Tablet says no MAC address found, and wifi settings app just hangs when trying to turn on.. I've re-flashed numerous times.. I've formatted all the partitions, re-flashed again....
Any ideas?
I had to flash the rom again (EOS cornerstone) and the wifi started working. I just ended up flashing the stock ICS from the asus site to start freh again.
It seems like the backup in CWM does something strange with the wifi driver.
I'm start a new thread here.

I reflashed EOS, wifi works, but i now have a different MAC address than I did before.

Friend's SGH-i727R Wifi turning on?

Hi, my friend has an SGH-i727R, stock ICS 4.04 unrooted and with Fido Canada. He was upgraded to 4.04 about 6 months ago, and there were no problems with the Wifi then.
He came back from his holiday and his phone's wifi had been stuck in the "turning on" position for a long time, and nothing can fix it.
He doesn't have a data plan, and I've tried installing stuff like Advanced Wifi Lock and Wifi Fixer through his SD Card, but it still won't turn on. He's done a factory reset, but it didn't solve the problem.
Is it a hardware problem? I want to ask before I root and install a custom ROM for him.
EDIT: It was on 4.1.2
I would Odin the stock jb firmware and see if it's still an issue. If it is, then it's probably hardware.

[Q] android 4.3 and 4.4.2 wifi issues

Hi,
Since I upgraded the ROM to 4.4.2, I'm unable to find my network/WIFI router.
I have currently KatKiss-4.4.2_022 installed. Before I used 4.3 and sometimes I lost connection, but since I installed 4.4.2 I'm not able to connect on 4.3 neither (saved backup), but if I roll back to the stock ROM, I have no issues at all. Also I have no issues to find and connect to the network with laptop or with my phone (GT-I9100 with CM 10.1.3-i9100).
I did try to reinstall the ROM, tried all the regulatory domains, but none of them works. I also made changes to the router settings (channels, etc.), but no success.
Does anybody else have seen this issue? Any help appreciated.
Thanks

See if your router has mac address filtering set, or if it has a button to allow discovering or such.
MAC address won't be the same between stock and 4.4, it was already the case on katkiss 4.3 though if it was katkiss that you were using as your 4.3 rom that was working before ?
Try also to reboot your router, I've seen a few with wifi that stopped working saying that rebooting their router fixed it.
Beside that I don't really see much else, just the usual, make sure you do a full wipe, format /system and cache before flashing 4.4
in case it's something left over from other systems.
Also make sure you don't restore settings or system apps from the previous rom.

I am also having issues with wifi, but in my case it is more the distance from the router.
in the bedroom, which is just 4 meters from the router (behind 1 wall) I used to get nearly full signal wifi, after updating to 4.4.2 i get no signal at all, to be able to use the tablet I have to be 1 meter from the router. I reverted back to stock ROM but it doesn't solve the issue !!
is it some kind of internal firmware corruption, or hardware issues?
Try switching WiFi optimization off.
Basically if you go to settings then wifi and the click on menu and select advanced, then you can switch wifi optimization on and off.
On most android devices like tf101 ot lenovo k900 it helps to get a good wifi connection.

[Q] Strange problem with Bluetooth, Wi-Fi and Wireless tethering

Lately, I'm experiencing a lot of problems with my Xperia L. For one, when I turn on Bluetooth or Wi-Fi, the phone just hangs for about five minutes before finally activating them. The same case applies to when I activate a wireless hotspot on my device. When I tap on 'enable wireless tethering', the phone completely hangs. This has really started getting on my nerves! :crying:
Also, when I capture multiple photos from my camera, I'm finding that some images are automatically rotated. I have to manually rotate them, which, of course, is no child's play.
Another issue that I'm facing is that the phone's gotten a bit unresponsive. It doesn't fire up applications like it previously did (not that I have many apps installed too. Just 4).
All this has got me thinking, was the Xperia L a waste of money? No firmware upgrades coupled with tons of bugs!
Should I risk it and go for a custom ROM? I really need some advice, fellow users! Please reply as soon as possible! :fingers-crossed::fingers-crossed:

It seems like you are on Stock ROM. If you have not done it already, try do a factory reset i know its not an easy task but it may bring your happy days back. If you are not a big Fan of Sony UI you can try Many KitKat ROMS that are available updated with Latest sources 4.4.4.
Very soon we might have almost Bug Free KitKat Custom ROM's, Its your wish to Flash a Custom ROM. (Losing Warranty)
WIFI + Bluetooth not working even after Kitkat cm11 rom

I Also have this problem with WIFI and Bluetooth. Cant switch em on. I was on 4.2.2 update...
At first WIFI & BT are fine. About 2 weeks ago it starts restarting. When I'm lucky enough to reach inside the Setting and use phone for sometime, I tried to turn on wifi... Phone hangs... then restart.. Sometimes it takes several "auto" restart before i can operate the phone. But after those, everytime I turn on WIFI.. it hang/restart. Also happen w/ bluetooth.
I tried flashing/downgrade to 4.1.2 stock rom w/ flashtool. The restarting stopped/fixed... BUT, there's no way I can turn on wifi. i keeps switched off everytime i tried.
Finally, I installed CM11 kitkat cw. Everything looks new and fine ans smooth.. BUT... still cannot switch on wifi! and bluetooth!! >.<
I dont know what to do. Is this a hardware problem?? or is there a fix/zip i can flash to fix this??
HELP.

I resolved the issue! It's going to sound extremely silly, but it worked wonders for me.
Basically, I deleted all downloaded apps that require a 'Full internet access' permission (The one with the WiFi icon), and viola! WiFi and Bluetooth work wonders now. I noticed this problem when I uninstalled Cleaner Master, and WiFi and Bluetooth jumped to life.
This is, however, a major setback. I can now download only a limited number of apps..
But hey, at least WiFi and Bluetooth work, so I've got that going, which is nice...
Any reasons why this may be happening guys?

You should perform a clean install of latest stock ftf. Looks like there's a problem with your kernel too. So flashing will put a new life to your phone. Remember to do clean install of firmware including kernel and wipe data alongwith resetting customizations.

Totally dead WIFI

Wifi is dead. Unable to turn it on in settings, same for hotspot. Test in engineering menu fails. Reboot, connections setting reset, full wipe does not help.
Phone is 1mo old.
Any ideas?
Is the phone upgraded to the latest Asus release?

Yes, it happened on latest firmware (.145)
I had this issue when I first got my phone and upgraded to A10. No wifi, it wouldn't even turn on. I downgraded to Pie, configured and connected the wifi and then flashed back to A10 and it worked.

I've tried downgrading but that did not help
Sounds like a hardware issue.
