Another Wifi Problem P6210 (SOLVED)

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.

Wifi disconnectiong after 4.04 update

I've updated my phone 2 days ago.. and I wish I didn't..
My latest issue.. WiFi disconnecting all the time after just a few minutes.. I've already checked wifi settings and wifi sleep policy.. Anyone has more tips to look at the problem?

does it happen only when your screen is off?

I know HTC have smartsync which turns wifi and data off if it is not used
this plays havoc with me at night between 12.00am and 07.00am.

Doesn't that completely prevent your phone from going into deep sleep? Aka drain the battery ridiculously quickly.
I don't understand why HTC can't just get this right. I've never had any other phone that had trouble receiving notifications on Wi-Fi.
-Sent from my HTC One S.-

Same here. I tried every setting. Just have to restart my router every time before connecting. Annoying but working. And after the update the wifi signal is the worst. Much worst than before.

After updating to 4.04 I have the problem that connecting to my Wifi router is no problem, I get full signal (!), but actually using the network is nearly impossible! After using several apps and/or putting the phone in and out of flight mode, i sometimes regain a real connection, but in the morning or after returning home it's gone again...
The disconnecting in sleep mode and not always receiving messages I can live with, not being able to use Wifi at home and thus being forced to use 3G I can't. Anyone have similar problems and also know a solution? I'll try rebooting the router next time, could be a temporary workaround.

I have the same problem after the 4.0.4 update. Wifi signal is incredibly bad now when I previously did not have any issues.
Tried Best Wi-fi performance and its still not as good as the default settings on 4.0.3.
Anyone has any luck factory resetting their phone to restore Wi-fi functionality?

Differents roms, kernels, making all can i do on the recovery, factory reset wipe cache dalvik cache fix permissions, reinstalling the ruu 2.31 and doest work the notifications via wifi and the screen off (mode deep sleep) and NOTHING WORKS i am starting to thinking maybe its a problem of hardware/wifi?

I have the same or similar issue.
My wifi disconnects every minute, even when the screen is on and when I'm using it. I got a replacement phone from T-Mobile and and replacement antenna cover from HTC but still have the same problem. My previous Nexus S and HD2 had no problems with this the wifi and the wifi disconnects on all networks I've tried so far so it doesn't seem like an issue with my router.
I tried a network monitoring app and the wifi disconnected over 350 times in 6 hours.

Hello guys, my brothers tablet seems to have a problem. It cannot connect to the wifi literally. He factory reset the whole thing , and its stocked. But it just randomly happen yesterday when he was playing castle crasher, my tablet seems to be working fine on the router. But the problem is that when i press the button to turn on the wifi, it won't even turn on. It will still disconnect the button. So he cannot even access any wifi or anything. I tried looking around google to find the answer but it seems to be not a problem. My brother hasn't drop his tablet or anything. Its model number is the GT-p3113 if you can help me that would be so grateful thanks.

wiping cache doesnot need rooting you can do that even when your phone is not rooted

Wifi disconnect

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?

Connectivity Issues

I've got the unlocked version of Note 20 Ultra. Recently I started experiencing connectivity issues on both wifi and cellular. Basically, internet connection disappears. When on WiFi I still show as connected but have to turn wifi off and back on. Same on cellular connection, it shows good signal but there is no internet connection. When driving, my music would suddenly stop streaming and I have to turn airplane mode on and off to get the connection back.
This is really frustrating. I'm wondering if it's one of the recent OTA updates that screwed my phone up. It's happening several times a day and is really not acceptable. Anyone else experiencing this or perhaps some advice on how to fix?

Reset network settings. Then check it also in safe mode for a few hours and see if symptoms still persist.

Play with it. You need to hit the right buttons at the right time or it will just reboot normally.

Reset network settings and cleared system cache. So far so good. Will report again after a day or two.
Thanks for the advice.

As a side effect, the overnight battery drain has decreased significantly

Well, it just happened again on WiFi
