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)

Every time I turn wi-fi on, it simply says "Unable to scan for networks". Does anyone know how to fix this. I hard reset and that didnt help.
Try a full power outage. Pull the battery. Sometimes you need to clear voltage from hardware (especially radios) in order to clear the glitch.
If you find it necessary to do this a lot, there is a deeper problem.
If this fails, take it into the store.
I took it to the store and they said its a known bug.
They said they are fixing it in an update soon.
I don't know if its true...

Do you have wifi set to "never sleep" in wifi settings??? Also if your running spare parts+ it also has an option to set wifi to never sleep. Also are you running any apps that puts the phone to sleep??? Also in display settings try changing your screen off time to 10 min.
Locked & Loaded
I tried the "never sleep" setting in spare parts, but the setting doesn't hold when I exit the program and open it again, it goes back to "android default". I don't see anywhere in the phone wi-fi settings to change the sleep options.
I'm unaware of any apps I'm running that put the phone to sleep, and I'm not sure what the display settings accomplish but I can try it.
None of this happened before, only thing that really has changed for me is that I got the iGrip car dock and the phone has seen dock mode a little bit. That and I went to a house with spotty wi-fi and my phone would connect and disconnect at the range of the router. I've had other issues with app/camera freezing, I'm hoping it's sd card related or perhaps due to ota's not taking correctly. I'm gonna try a sd card format/phone data reset to see if that remedies all the issues, otherwise I might go in for an exchange.

BS. You shouldn't have to wait for a custom rom for your phone to be running normal. Take that **** back again.
Sent from my 3rd Dimension of Evolution
This happens to me. I have noticed it only happens if I have had my phone get below 30% battery at some point and the power save mode kicks in. For some reason it is not switching it back once power save mode is disabled.
Sent from my iPhone with the bigger GeeBees.
The setting isn't located under Wi-fi, look under Power, you should see the options in there. Turn power saver off, or adjust it's settings, and see if that helps, I wouldn't use spare parts
I did a full phone/sd card reset, and the problem STILL exists for me. Spare parts did restore itself as one of the applications that got restored, I uninstalled it without running it though. My phone settings seem to have gotten reset as well. I don't get it, my phone was fine even with spare parts installed before.
I might try another reset and see if spare parts still restores itself.

The Atrix has a driver related issue that causes problems connecting to WiFi access points in certain countries. I'm pretty sure they have figured out a workaround over in the Atrix XDA section, sorry I don't have a link for you.
Hi,
My name is Fisher, I have the same problem, I have the phone in Australia and I updated over wifi then my wifi just says error underneath it, also 4G does not work. I can turn wifi on by first putting the phone into aeroplane mode then restarting and turning wifi on while still in aeroplane mode. I have managed to get all working occasionally by having aeroplane mode and wifi on, then going to system updates which are greyed out then turning off aeroplane mode by holding down the power button and when ive done that i have a second or so before the wifi dies to click motorola software update that is now not greyed and it sometimes kicks everything on;-)
I have tried factory resetting the phone 3 times and formatting internal sd on third time, did nothing.
Now i have some dmesg logs with the wifi under error, working in aeroplane mode and all working with my trick, so let me knowif u want them all.
I have a feeling the issue could be a sprint app or process that disables it, look at the access/security settings for sprint zone, it can control wifi, everything seems to be briefley activated when i start the phone in the notification bar then wifi and 4g die, so maybe a sprint process detects that the phone has not activated or something and kills wifi and 4g.
I have reported this on the motorola forum in the thread someone else started, look for " motorola photon wifi error" in google and it might be the first hit.

Wifi ERROR after OTA update
hello everyone
i am not a US resident and i bought this amazing phone i am using Cellcom Israel Sim card
i just saw the firmware update,the update run smooth but after the reboot i try'd to turn Wifi on
and getting an ERROR.
try'd to reboot the phone - wifi not working
try'd to pull out the battery and restart - wifi not working
the only thing that works is when i restart the phone in AIRPLANE MODE the wifi works
but soon as i turn the AIRPLANE MODE off the wifi disconnected and cannot turn
it on again until turn back the AIRPLANE MODE again.
i do not using any data plan connection i dont have any...
what can i do??
Just do a factory reset. That will solve this problem.
Its a known problem. Lot of people are facing it after applying OTA. Just do factory reset and you should be fine.

Factory reset doesnt do a thing bro
Hi, I had the same issue actually watch the router and say the wifi connect and then drop, i installed wifi manager and then for some reason it started working and i haven't had a issue since.
no sure why it did this but i also restarted the phone multiple times trying to get it syncing and it wouldn't until that program was installed then after i got connected i uninstalled the app and it still connects without the app
got installed "wifi manager" and again error "error enabling wifi"
Factory resetting does nothing for me, I even formatted the internal memory as well on the third time, the only way so far I have managed to turn wifi and 4g back on and also data as data seems disabled is by:
Enable aeroplane mode, restart and then enable wifi, then go to system updates and you will see the 3 options greyed out, disable aeroplane mode by holding down the power button then click on update motorola software and most of the time that has worked for me.
kc_sheets mentioned installing wifi manager, I have installed it but not restarted my phone as I've managed to get it all temporarily working and Ill test the wifi manager when I have to restart.
Let me know if anyone else can get them all working using my method.
For troubleshooting, I know dmesg is good and probably lsmod, what other linux info can help me find out what the issue it, I would not be surprised if sprint has done something to disable wifi, 4g and data as the phone starts up, but it looks like it only disables at the last minute, does anyones wifi connect as you start the phone up, I think mine may have done.
I'm hoping we can just rename the process or app that is the issue and have a non crippled phone what we paid good money for.

just flashed the phone and guess what??

Posted on motorolla forum:
Hey guys, same problem - briefly:
Sprint customer - overseas for the next 6 months,
1. OTA update successful, achieved over wifi
2. phone restarted, wifi connectivity lost "error" as with fisher and the rest
3. airplane mode allows wifi connection until GSM is connected again, at which point it gets knocked off
4. I /also/ fat fingered my phone during one of the restarts and had both wifi and GSM working, but it's my nature to test things, so i restarted and of course now it's gone.
5. I am not able to attempt wally's re-register with Sprint approach as I will be away from the states untill January
6. I tried the update sprint zone fix - no luck
7. I tried the disable roaming guards - same as fisher, some of them are green and grayed out, no luck
Thank you !
I've done a quick search of this forum and [ALARMINGLY] can't find a solution (or any references) to a continualy cycling reboot on my daughter's day-old Sony Tablet S.
What's happening is, the system boots, I see the unlock screen for a few seonds and then it reboots again!! No time to do anything.
The power button (in combination with either of the volume buttons) doesn't do anything when the boot animation is being displayed. And the reset button (in the tiny hole) simply turns the tablet off, but the cycling reboots start again when powered back on.
Just so you know, I have owned and used the Morotola Xoom since August 2011, so do have some experience with Android Honeycomb, but nothing like this. Oh, and I have not attempted to root either machine.
Here's what I believe is the cause: I was copying a file off a network share (using a third party file manager), but it was VERY slow. The transfer mustn't've finished when I turned the tablet off (completely) for the night.
Therefore, I assume it is trying to resume the transfer, but there is a problem (possibly the WiFi connection is slow to connect). Nevertheless, I would have thought Andorid was more robust than to simply reboot... an error message would be a bit more "professional" and much more welcome than a cycling reboot that does not allow me to do a F%^&$#G thing about it!!
PLEASE HELP or point me to a forum that may be able to.
Thanks in advance.
Wow. That tablet is toast. Something must have been corrupted when you turned it off.
My girlfriend had an HTC Sensation 4G that had similar problems the day she bought it. HTC and our cell provider gave us the run around denying responsibility. We rooted it and flashed a new ROM which completely fixed it though. In your case for the Tablet S this solution is impossible as the tablet hasn't been rooted yet.
Return it to the store asap and tell them it's not working properly!
Have you tried the reset button on the side underneath the volume button. Just stick a pin in thhere and hopefully voila.
Let us know if that works.

Yeah, mightyfo, I did. Thanks for your reply, though.
Anyway, I have attempted a few more "fixes". Among them was to delete the partial/currupted files from the SD card, without result. Then, for some reason, I turned off my WiFi access point, and, bugger me, the tablet booted! I turned the WiFi back on to be certain it was responsible for the problem and, yes, the reboot cycling started again.
Obviously, I turned off the WAP again, booted the tablet and killed the saved connection. Once I turned the WAP back on, I re-established the connection and the tablet has behaved ever since!
Just so you know, I did have the latest System update (v3.2.x) when all this was going on...
Makes me wonder if it is an Andorid issue, or something Sony have done while tinkering with Andorid. I just hope my findings can help someone else in the future.
Sounds like you need to do a system reboot.
Comprehensive explanation of the problem
Please take a look at the following very thorough explanation of the underlying cause of the reboot problem:
[Can't post links] Search for "android stops renewing lease" in Google and select the Princeton link (should be top of list).
My fix was to turn off the WiFi AP (to stop the reboots), delete ("forget") the connection and then set a static IP outside my DHCP range.
Hope this helps someone else...
Hi,
This morning I randomly decided to update my firmware (as per Sony's incessant reminders). I updated to 17.1.1.A.0.402, as it was what Sony's updating app was telling me the latest firmware was. I updated as instructed on my tablet, wirelessly. The update was successful and totally uneventful -- no incidents whatsoever.
However, immediately after my update, my wifi dropped, and after that, I couldn't reconnect to *any* wifi network whatsoever. I toggled on/off, and the wifi would reconnect for a matter of seconds, maximum 2-3 minutes before dropping and never reconnecting again. To reconnect to wifi, I'd have to toggle off/on again and then would have seconds to try and load a page (but would never succeed)
So, I updated the firmware again, this time using the update application for the Mac since my tablet could no longer connect to wifi.
I successfully updated to 17.1.2.A.0.314.
Still the same wifi dropping and not coming back issues.
Then I tried "repairing" my software from the Mac, which I'm lead to believe erases everything and flashes with the most recent firmware.
Still had the same wifi issues.
Then I tried an erase/factory reset directly from the tablet.
I still have the same wifi issues, but they don't kick in within seconds anymore. Now after several minutes, the wifi will drop and not come back.
Any suggestions for a fix? I'm as of yet unrooted, and would like to remain that way if possible...
Thanks!
I would suggest a factory reset after flashing the update. Might solve your problem.
Before that you could try to delete your Wi-Fi and set it up again...

Thanks for your help
"Repairing" from this Mac app is flashing the update, correct? It erased and then flashed anyway. Had to set up the tablet like it was new. Is that not a factory reset?
In any case, I did a factory reset immediately afterwards, from the settings screen of the tablet, as mentioned above.
By "delete your wifi" do you mean "forget" the networks I'm trying to connect to? If so, I've done that many times, and have had to re set up my wifi networks anyway upon each factory reset/flash/erase.
So I think I tried what you suggested, and no dice, unless I've misunderstood?
Perhaps worth noting: I'm using the accompanying Sony Bluetooth keyboard.
Wifi seems to stick around a bit longer when Bluetooth is toggled off (no keyboard), though I could use the Sony keyboard before the update, no problem at all.
Yes that was what I ment.
Sorry it didn't help solving your problem.
Seems like you should call Sony.
It's the Bluetooth. Wifi and Bluetooth are on the same chip and won't work at the same time. It's a hardware fault with pretty much every Android system I've used. Turn off the Bluetooth and your wifi will be fine.
Thanks for your reply – though it was possible to use the bluetooth keyboard at the same time as wifi before the update.
Bluetooth keyboards would be pretty pointless if you couldn't use wifi at the same time as you use the keyboard, wouldn't they?
Between the Sony Xperia Z2 tablet, a Samsung Galaxy Tab S, and an iPad, I've used all with bluetooth keyboards + wifi without issues (until this firmware update on the Z2).
Use 5GHz Wifi, then the problem will be solved.
Sounds like you have been lucky so far and due to the small amount of data a bluetooth keyboard transmits. Bluetooth headphones are always transmitting as is wifi when watching hd youtube videos. They will always interfere with each other, but only every minute or so. Google the problem and you'll see its pretty universal.

Hi, here's my experience with my Z2 tablet, unrooted. I too have had wifi problems: after using the tablet fine for a while, with a strong signal, the tablet drops out, then wifi access stalls whilst "Obtaining IP address". I sometimes use a Bluetooth Microsoft keyboard, but have had the wifi drop out when I have Bluetooth off.
The only reliable (so far) solution I have found is to move to a static IP address. Not ideal, and perhaps not much help when travelling, but an OK workaround for a home or other wifi network where you have admin access to the router.
Hope that helps. Apologies if my newbie post is naive.
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
