Wi-Fi problem in JellyBean stock ROM - Samsung Galaxy Tab Plus

The latest official firmware P6200XXMD6 has problem in activating wi-fi.
if I turn on and off wifi several times(i think), wifi cannot be turned on again until you reboot. When I try to turn on wifi in settings, it will only stuck in "turning on...". I have faced this problem several times because juice defender turns on and off my wifi (in order to save battery).
Is this normal, I mean is there a bug in this ROM that prevents wifi from turning on if you turned on and off wifi several times before?

I have also had this issue ,but mine went away by just uninstalling one of my antivirus programs (uninstalled Avast and kept lookout and one mobile care ) and now i have not seen this issue in months.Could this be caused by to many antiviruses or just perhaps a bad combination of a few apps?

Atrix 2 known wifi problems?

I have an Atrix 2. It has been replaced twice by AT&T due to this problem. I have factory reset each phone and tried every battery mode, data saver, sleep policy and wifi channel.
The problem:
The wifi turns off by itself! not sleep, off! As in the checked box is unchecked. The phone does it during use and when not being used. The timing between instances is random. The wifi sometimes stays on for hours. Other times it wont last five minutes. I have 4 other wifi devices connected by wifi to my secured router.
Note: I travel across the country for work and the problem occurs at airports, hotels, mcdonalds, ect.
I have called Motorola and their only option is to send it to the with no replacement. I could use some help. I have been searching online and others with this problem dont persist, they simply state that unsecuring their router fixed the problem. That is not an option for me as the routers are not mine.
Any input will be greatly appreciated.
Hi, I recently noticed this problem started after I installed the ATT Smart Wi-FI app. Mine will connect then turn off, wait a second turn back on then I get the WIFI networks avail message and I check it and it's not connecting to the network til I tell it too then it will stay connected all day.
I"ve had my atrix 2 for about a little over a month. It's doing the same thing. Wifi will randomly shut off. I have to go into the settings to turn it back on. It will work fine for a little while then just shuts off again. Does anyone know if this seems to be hardware or software related. I've tried different apps and WiFi sleep settings to no avail. I really like the atrix but this is kind of annoying.
I have the same issue also, except I have top reboot my phone for wifi to work again.

i have the same problem, it's not my wifi connection, but the actual wifi setting turns off whenever i turn off my screen and yes, i've set the wifi sleep policy to "never", so that's not the problem. i've also tried "never when plugged in" and "when screen turns off" and i still get the same problem. i was thinking about going to at&t and asking them about it but decided to come here first.
(a white iphone 4 is looking better and better ) can anyone help?
I had this problem but after I disabled the power saver option under battery and data (set it back to performance) it went away and Wi-Fi works perfect.
Tried different battery saver settings as well, nothing changed.

I want to know if any of optimus 3d user have encountered this problem, if not too much users have this problem, i will send back to lg for repair. I want to say when i switch on wifi for ten time. I will encounter this problem for three time no matter which rom or which version of android i am using.because i have encounter this problem in many roms

it's a common issue, not sure if just with GB, the problem with this is that your battery drains too fast when this happens
just check if the phone warms up if so u have an issue then just restart
lg has not told anything about this issue, they thinkg it's an specific issue from one carrier's fw but it looks like it's in general with GB, my old x10 had the same issue but no battery drain
But i have this issue when i using froyo. Now i am using froyo but have this issue two times a days. Its very annoying to me yo know

There isn't any real solution. It happens to me as well as to other people (search the O3D threads here and you'll find many reporting the same), no matter if you have Froyo or GB.
However, in my case it doesn't happen two times a day but less often. It never occurs when I wake up my phone and wifi reconnects. It only happens when I turn on/off the airplane mode (but not all the times).
Do you have this issue when the phone is waking up normally (with the wifi always on) or when you turn on/off the airplane mode or turn off/on the wifi manually?

if only occur in turning on/off the airplane, it will be fine for me as i seldom use the airplane mode. however, the issue occur when i turn on or off the wifi manually. i have tried to turn off and on the wifi repeated ten times when the phone restart, i have no problem. however, after i close the wifi for about 1 or 2 hour and enable again, it sometime have the problem when i switch on the wifi. i really have no ideas why this problem will occur.
Well when you turn the wifi on/off manually, I guess that it's the same thing (for the wifi connectivity) like turning on/off the airplane mode manually, so it causes the same problem.
Do you have this issue when you just wake up your phone (with wifi on)? If so, you could keep your wifi always on when you outside from home/work. If it's not connected it doesn't consume much battery.

when the wifi problem happens, i must reboot the phone manually, then the wifi will switch on automatically after the phone has rebooted. however, i discover that, wifi drain battery very much when compare to just open 2G network alone, therefore, i would like to close wifi when i just put it to standby. i think this is not a real solution and i have this problem two time a day. it is very annoying actually.
thank you for your reply!!!
I posted this already in thread i started labeled not too clearly http://forum.xda-developers.com/showthread.php?t=1519436
It's a process called tiwlan_wq which starts using cpu @ 48% constantly and drains battery quickly.
No idea how to solve this i've kept the wifi at standard setting of off when phone is in standby or even on always but this occurs randomly.
I thought new v20g rom would have sorted out some issues but no and i'm dead bent on selling this POS LG phone.

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?

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.
I am going to try this: http://www.androidcentral.com/how-work-around-wifi-disconnection-issues-htc-one-x-and-one-s

Hi,
Similar issue. The WiFi doesn't auto connect to wherever I may go.
It used to auto connect to previous WiFi that I connected to and entered passwords
when needed. If I'm connected and then go outside for a while and come it won't
reconnect. I have read a slight trick. I turn Airplane mode on then off and then it
will reconnect. Any ideas on this. Seems to have happened lately after 33r update,
Ken

WiFi Won't Stay On on Lollipop

I've encountered a weird issue in every Lollipop ROM that I've tried, where when I got to sleep with WiFi on, I will wake up the next morning and the WiFi will have disconnected. It will still be on, but the network I had connected to not work unless I toggle WiFi off and then back on. It's happened on 3 different ROMs on 3 different builds. Am I doing something wrong?

I'm not sure if this is the issue but have you tried going to your wifi setting-->advanced-->keep Wi-Fi on during sleep and change it to always?

Yeah, I did, thanks but it was already ticked.
You are not alone. I am having the exact same problem. The wifi doesn't disconnect, it just stops working. If i disable wifi and re-enable again it works just fine but only for half an hour ish.
Quite annoying for a whatsapp / fb messenger user .
Considering reverting back to KK backup until this is fixed :'(
