Two days ago, my device suddenly could not connect to any wifi anywhere, encrypted or not, WEP nor WPA. This began to happen after I did a backup though CWM.
It sees networks but continuously runs through a scanning, connect, disconnect, scanning cycle. It tries to set the IP from the network, but then flashes unsuccessful and starts scanning again and repeats the process, and in the list of available networks, all available networks cycle between being not in range, remembered or disabled.
Sometimes wifi networks are greyed out, sometimes, not. Sometimes it cannot even find my router, even if I place the Tab on top of it. It connects once in a while, randomly, but only holds the connection for a few minutes.
I have other wifi tablets and all can connect to my wifi, nothing has changed with my wifi settings, router, etc. But to make sure, I did cycle the modem and router on and off and even reset the Airport Extreme that I use to factory settings. Modem is new and Airport Extreme is only a couple of months old.
My Tab is rooted and running stock HC. Never been dropped, great condition, never exposed to shocks, water, etc.
I have tried the following fixes:
Restored to factory settings, wipe data, etc. Nothing. I have tried this several times.
I have tried setting a static IP address. Nope.
ODINed it back to stock using P6210XARKL1_P6210UEKL1_HOME.tar.md5. It briefly connects to wifi long enough to apply the update and after that, it starts cycling scanning, connecting, disconnecting, etc. Tried this several times as well.
I even tried the update to the UK ICS for the P6210 and have the same problem. It sees wifi, but cannot connect, and on occasion it cannot see any wifi at all, even when I am 2 feet away from the router.
At this point I am convinced that it is a hardware issue (either that or it is pouting because there is a new Nexus 7 in the house)
Anyone have any other suggestions for a fix?
Update:
I did another hard reset from within Settings-->Storage--> Factory Data Reset, rather than through recovery (either stock recovery or CWM) as I had done before.
Now, wifi connects a little more consistently. Would resetting that way actually make a difference? Or is this just a random thing? Am I trying to see a logic where none exists?
How would a hard reset through the system settings be any different than one through recovery? Or, does each reset clear something else that got corrupted along the way?
My wifi still randomly cycles through scanning, connecting, disconnected, just as before. However, now the connection is actually made more quickly (under a minute when before it could take up to 15 minutes - or just never connect) and seems to remain connected for longer periods of time now.
Well, after searching and reading through 100s of similar issues one of the workarounds is to use a wifi widget or a WiFi Fixer App.
I am using a widget to control wifi and it along with any other random thing I might try can occasionally make my Tab connect to my Wifi network.

Persistence = Profit.
I think I have finally solved the broken wifi issue. Just to recap, the problem started after I did a backup with garyd9's CWM http://forum.xda-developers.com/showthread.php?t=1379532.
And as a last ditch effort I even tried toggling the wifi on/off with a widget as was suggested from other sources (Google is your friend), in addition to factory restores, or restoring from a CWM backup, etc. And that was not a reliable solution after all.
These are the steps I took.
Through stock recovery, I wiped data and cache, and did a factory restore, twice.
I ODINed back to stock, again.
Wiped data and cache and did a factory restore.
Wifi was still sluggish to connect, but finally I was able to load the update.
Then I wiped data and cache and did a factory restore again.
It has been 24 hours and I still have a strong wifi connection. If I power my Tab off and wait an hour or two, then reboot it connects immediately to wifi. If I toggle wifi on/off it still makes an immediate connection. YAY!
So, it seems that something got corrupted during the initial CWM backup and then persisted through many wipes and reinstalls.
UPDATE:
Still have working wifi!
I'm having the same problem now. I'm using latest CM9.
I was using Google Chrome just fine when suddenly Wifi disconnected for no apparent reason and it's now showing the same symptoms you described in the first post. I have formatted cache and cleared dalvik cache and it didn't work. Wiped everything and it didn't work. Reflashed CM9 and tried two different Wifi fix flashable ZIPs but I still got the problem. I'm wiping everything and reflashing CM9 once again.
Is someone else experiencing this?
I'm afraid to data wipe in stock recovery due to the brick bug reported (my tab uses one of the defective chips).
How is your Wifi holding up, VitaZora?
I hope persistance pays off.

My Tab also has the defective chip, but I didn't know that until AFTER I went through all those wipes and reinstalls.
But I can report that all is well and wifi is still working like a charm.

Ohhh I see...
I did wipe in HC stock recovery several times, but not in ICS stock recovery.
Have you wiped in ICS stock recovery? By selecting "Factory default" option from config menu or by manually going to recovery and selecting data wipe? Or both? Hahaha
Thank you for the reply!

Honestly, I can't remember. I know I flashed ICS twice as well as the CM9 version for our Tab.
I think the order for flashing from rooted HC was the following:
ICS, CM9, HC, HC, HC, ICS, HC.
In between each was either factory restore from the config menu or through recovery. Occasionally after flashing my device back to stock, it would go into a reboot loop and the only way to fix that was to enter recovery and wipe everything. But I reflashed so many times and tried wiping and factory restores multiple times as well, that I may have wiped ICS through recovery - in fact I am sure I did at least once.
Oh well, I guess I live dangerously.

Carefull! ICS stock recovery may brick you're tab. See this thread
Hello.
Yesterday I decided to try out ICS and then upgrading to JB... I flashed the roms correctly but the wifi wasn't working at all so I went back to stock and the wifi wasn't working either! The weird thing is that I'm connected to the wifi and it says connected but I don't have internet connection and my laptop does has internet connection so I don't know what it is...3g is working well but my wifi is not. Also the text messages arent working well. For example I send a message at 7:10 am and when someone answers I get the message at 9:11 but it's actually 7:11 am so they go on top of the message I just sent instead of going down like it's supposed in a conversation.
Thanks in advance.

I did the factory reset and nothing... What can I do now?
The other day I bought the samsung infuse from a guy, and he told me the wifi wouldn't turn on, so I assumed it was a software issue.
This is everything I tried:
-Factory Reset
-Flashed back to stock with root with Odin
-Flashed Flashed ICS recovery
-Flashed Beanstalks Rom
-Flashed CM10.2 Rom
After all of these steps, I still can't get the wifi to turn on. Ive also tried all the fixes I found online, dialing *#*#526#*#*, with fixer app, etc. Could this be a hardware issue?
Did you try turning wifi on when using the stock rom?

Yeah, it wouldn't turn on then either.
So I was looking t qkster's How-to on installing roms, and under the wifi fixes, I tried all of them, and FXR wifi fixer gets stuck at 'Deleting Profiles'. Still can't get it to turn on, could somebody please help?!?

It's not a MAC address issue for me as far as I know, I just can't get my wifi to turn on period. Like I can't even get to the point where it will scan for networks. Also noticed my bluetooth won't turn on, but I don't really use it.

try to use the code *#*#232338#*#* and check if the wifi mac address is available.

After browsing a bunch of forums I still can't find a fix... 160 views, So I'm not the only one having the problem. Surely someone can find a fix, I need wifi, I have a data limit.
So I flashed back to stock, and tried to flash drivers, and it said they installed successfully. But on stock GB it will turn on, scan, then turn off, not detecting any networks. Help??

Troubleshooting this require several directions.
1. Make sure the router or the wifi source is working properly. Are the other devices picking up the wifi signal also?
On the router, there is a dhcp lease time...set this on a different setting, ie..from Forever to 2 wks ..etc
2. Back up your data and pics etc and take out the micro sd card. Factory reset and data wipe with full format a few times from in the ROM. Boot into cwm and reset again.
The flash to complete GB stock - heimdall or odin with a complete re-partition - and try to run it stock. Try reseting the router again.
3. Open the phone and check the connections, remove the circuit board and the connections. See if anything is loose or corroded.
If after this and your wifi won't turn on, it could be hardware.
The easier solution is to take it or send it to a repair shop..repairuniverse and mobiletechvideo are two examples I've seen on other posts

Yes, all devices in my house are receiving wifi. I've done all of the above except for open my phone, which I don't have the means to do. This weekend I'll be taking it to a repair shop to get looked at. I'll let you guys know if they fix it, and what the problem was.

yeah...i noted that you did..couldn't hurt to try it a few times though...sometimes, wifi doesn't work right due to voodoo or partition mismatch..only a repartition or complete reset a few times with reformat may fix...

Turning WIFI on...
Ok, so i've spent the last few hours trying to troubleshoot the above error... and i have a solution that worked for me... I couldn't turn my wifi on at all... it just said "Turning WIFI on..." in trying to fix the issue i was trying to download WIFI Fixer via 3G... which failed with error 492... so i followed the advice on this thread http://forum.xda-developers.com/showthread.php?t=1641114 which inadvertantly fixed my WIFI... So basically I cleared all Data and Cache of both Google Play and Google services framework... rebooted into recovery wiped cache, and cleared Dalvik cache, and my problem was solved... i hope this helps someone else.
Recently I have been experiencing Wifi disconnects every 2-3 hours. I have tried Wifi settings by clicking on connect, tried choosing forget and resiging in and tried the app Wifi fix but all the app tells me is it is "completed" but it is not. The only way I can get it back is to reboot but then it only fixes it for a couple hours. I thought it might somehow be connected to the rom (CROMI-X 5.2.4) though it has never happened with any rom before. So, I reinstalled a older rom (CROMIX 4.7.0) which was always stable for me in the past but it started doing the samething.

Go into setting/wifi/advanced In there make sure you WiFi region is set to your area... Try unchecking some or all of the optimization for the wifi... See if that helps, let me know.. As always thx lj
The only thing I have checked in Advanced Wifi is Notifications Wifi on during sleep is set to never. As for right region I.m not sure what you mean, my mac and ip address' are correct.
Check your router as well. In my experience routers cause a lot more wifi problems than people realise.
It's worth rebooting them every now and then. Also download wifi analyzer and make sure you aren't on a channel with a lot of neighbours.
DIdn't you have a NetGear router? The latest firmware was known to cause issues. Did you downgrade it?
I rebooted my router and I moved to another channel, so now I will wait and see. What I do not understand is when I lose wifi on the Asus I will ask my wife to check the wifi connection on her tablet and hers is fine?
Well guys, I did everything you suggested and it is still doing it. I am now running 5.3a. Has anyone everheard of the wifi just suddely breaking on the Asus? The reason I ask is that even though I broke my Asus warranty I do have a square trade warranty.

Try flashing back to pure stock from Asus or a clean install at least.
When doing a clean install but I want to save whats on my internal card can I just move /sdcard to my pc before I do a full wipe or should I move other stuff also? What do you suggest?

If you just wipe from TWRP it only wipes you apps and data. You won't lose any media stuff so pictures, music, videos etc will stay. You should do a titanium back up if you want to restore apps and data.
If you choose format you will lose all so yes you would need to backup to either your PC or external SD. But you don't need to format to do a wipe.
Did a clean install and now wifi no longer stops.
I am having another problem, playstore apps updates or new apps do not seem to ever finish d/ling, the blue line just keeps running forever. I have tried stopping and restarting but that does not seem to do anything.
Should I post this as a new question?

Hey Guy,
I can not connect to our WLAN in the University. It is secured with PEAP and MASCHVAP2. Android wont connect. Does someone have this problem too? Does anybody have a Fix?
Same Problem :/
I'm experiencing the same problem here. I'm trying to connect to the company Wifi here at work and it's failing, although it is working for all of my coworkers that are not using Lollipop.
The Wifi is configured as a hidden SID with PEAP security. My phone tries to connect, then briefly shows "connecting", then after few seconds goes back to "saved". I would imagine it's going to drain my battery because it tries to connect every 10 seconds, repeating the pattern described above.
Does anybody know how to fix this?
i think i didnt had that issue today everything was ok...i will check next time
Really? Wow, but i cant believe that nobody had the same issue while preview.

My WiFi is working fine. PEAP/MSCHAPV2. Win2k8 R2 running RRAS, AD user authentication, and WPA2 Enterprise on the WAPs.
Did you Upgrade or installed a Factory Image? And How do you Installed the Factory Image?
I remember, that i have not made this step: ★Select "Wipe data/factory data reset", could this be the reason?
Same issue
I'm having the same issue. I installed via factory image
Did you Wipe/factory data reset after flashing the Image?
I'm connected fine with WPA2 enterprise using PEAP/MSCHAPv2. I flashed the factory image last night manually without wiping data (ie. I didn't flash userdata.img). Not having any wifi issues at work today. Sorry, I know that doesn't help you get yours working... but maybe collecting information about who it's working for or not working for and how they upgraded will be of some use.

I did what the flash-all.bat script does, except I didn't flash userdata.img. Although just now I wiped cache for another reason and now my wifi is having the same issue as yours. It doesn't appear limited to PEAP/MSCHAPv2, apparently... looks like wifi on Lollipop has some real problems: https://code.google.com/p/android/issues/detail?id=78702
I might be flashing back to 4.4.4 because I need to have wifi working properly... too much of a deal-breaker for me if it's not.

I tried forgetting the network and setting it up again from scratch and now it connects fine. Not sure what happened, but now it works... doesn't change the fact that a number of people are having wifi issues with 5.0.
Hm, can someone, who has these problem, try to flash without userdata.img?
I sideloaded the OTA on to a stock, unrooted N5 and can't connect to my company's PEAP network with no Phase 2 authentication.
Got on to my work wireless using PEAP/MSCHAPv2 fine - sometimes notice a small exclamation mark next to the WIFI icon on the status bar, doesnt really tell you what it means but the connection seems usable and ok.
Used flash-all last night
Same issue - cannot log into company wifi after flashing factory image using flash-all including userdata.img yesterday. I don't know how to check what type of network it is but in Wifi Analyzer it says it is WPA2.
It was fine in the final L preview.
My home wifi that uses WPA/WPA2 PSK works too, so is connecting to wifi hotspot from another smartphone.
Hmmm... Have you all tried rebooting your device? For me, Wi-Fi isn't working on every other boot. I did a clean install of Lollipop too. My wife's Nexus 5 seems to be doing it too...
Okay, I now have rebooted several times now and it is working each boot now... WTF... well whatever. :\

If you have a exclamation mark on your wifi it's not working. You are using your wireless data. Try switching off your wireless data while using Wi-Fi and see what happens.

I have rebooted about once or twice at work but same result. Do you think more reboots would have worked?
I was mistaken, mine isn't working at all using PEAP/MSCHAPv2 ... Tried multiple reboots but i never get an IP back
Looks like i'll have to roll back to KK 4.4 as I need my phone on the work network
Edit - now it seems to be working - what the hell lol ... this is random! Ok it's connected fine and i can access stuff, but i still have an exclamation mark on the wifi icon.
