L9 P760 Wi-Fi stopped working. - LG Optimus L9 P760, P765, P768, P769

Hi, i bought l9 from orange romania 3 months ago. since then, in the first month i managed to update it to official Jelly bean, unlock bootloader, install CWM, and then ofcourse, root. everything went fine except until yesterday when the Wi-Fi suddenly stopped working. When i tried to turn it on it was stuck at Turning Wi-Fi on. I even tried installing CyanogenMod 10.1 on it, with no luck.
After my unsuccesful attempt with cyanogenmod, I also tried restoring a rooted CWM backup of a stock rom. Same problem, wifi doesnt start at all. What should i do?
Thanks in advance!

I had the same problem but I don't remember how I solved it exactly. I have done something in service menu or installed brand new one with kdz.
Try this: http://forum.xda-developers.com/showpost.php?p=41486538&postcount=3

It didn't work. Same problem. Wi-fi hanging at "Turning Wi-fi on". Also, wi-fi mac address , under settings is "unavalaible" and i can't even turn on Wi-fi tethering. Flashing Original KDZ is my last chance. I'll be back with a response as soon i'm done.

L9 stuck "turning wi-fi on"

I also have an L9 and started having the same problems last night around the time of your original post. The only difference is that I haven't rooted the phone. There have been recent android updates, however. Any more suggested solutions?
Thanks.

Well, i think there is nothing left to do other than sending it to warranty. I'm still open for suggestions.

kdz didn't work?

take a look what logcat is saying

This is what logcat is saying. Another question. It is safe to flash v20.kdz using offline method for fully returning to stock?

LE for users having the same problem. After sending it to warranty they changed the "faulty" motherboard. Now wi-fi is working just fine. Seems that i've got a problematic unit in the first place. Even though i unlocked the bootloader they changed it under no fees.

[Q] Wifi not working after 3588 update

Hey,,
So I received my G tab today and connected it to the internet and downloaded the update (Tap UI V.1.1-3588).
However, after the update got applied, when I try to turn on Wifi it says error. I tried to restart the device twice and on both times the wifi worked and actually connected to my network but then disconnected and went back into displaying the error in matter of seconds. I have searched the forums but it seems no one with stock Rom have had this problem.
Thanks in advance
I had issue with the stock fw, never ever after 3588 was ok, even when reinstalling
Try a new firmware. Maybe

I've got the same issue here. After restart I have Wifi for a couple minutes then it disconnects and errors until the next restart. This is my second G-tab and my first one works great.
P.S. Other ROMS didn't help my condition so you may want to pursue return before attempting Rom upgrade. I'm back to bone stock and still not joy.
It works now !
All what I did is close the wifi as soon as it starts, gave it a minute then turned it on.
Now I'm not sure if I should do this each time i boot it up, but, it works !
Try doing that, maybe it was by chance that it worked with me .

Wi-Fi 'stuck' then can't disable or re-enable Wi-Fi

Hi all,
I've started to have an issue with my HTC One X+ where it won't automatically connect to (any) Wi-Fi.
If I then go to settings, Wi-Fi appears as 'Disconnected' but the slider button says 'On'.
If I try and turn it off, it wont turn off. Then 'settings' ends up hanging.
The only way around it is a reboot, but this happens every day now, seems to normally happen when I return home and expect it to drop 3G and connect up to my homes Wifi (as it always has done?).
I really don't want to do a factory reset... I can't say that I've changed anything to cause this...
Does anyone else have the same issue and have you been able to resolve it?
Thanks
I'm having the same problem, but for me I know it didn't start happening until after I did the update. Not sure how to fix either.
Are you both on stock ROM?
I had similar problem after OTA update from AT&T. It was worse than yours since I wasn't able to enable WIFI at all, it just stuck on the "turning on" state. I was able to fix the problem by re-flashing the boot.img following this post:
http://forum.xda-developers.com/showthread.php?t=2235248
Btw my phone is rooted but running the stock rom.
Hope this helps.

Yes I'm stock and locked right now because I have some problems I need to return the phone under warranty for, and I have the problem where it is just stuck trying to turn on. Thanks for the link, but until I switch this one under warranty I don't want to do any modifications to void the warranty. As soon as I get the new one I will be unlocking and rooting it immediately, not doing so is killing me right now.
Well just reboot in bootloader mode and flash the correspondent RUU. You know how to find the good version?

[Q] 4.3 disrupted wifi, now can't fix

Hi all,
I've been happily following the progression of ROM developments, since I got my P7510 (P4WIFI) and sampling a variety of ROM's up through the versions of Android. I recently upgraded to a 4.3 ROM and developed a problem...I could connect to wifi as always, but could not get internet access (wifi connected, but no browsing, play store, weather apps, etc.).
I worked my way back through a number of recovery backups, knowing that in all of them I didn't have this problem, but it remained.
In desperation, I unrooted and returned to stock and the problem was still there! I found a .pit file for the 7510, re-partitioned, formatted the partitions and reloaded the stock ROM...still no change.
Can anyone point me to a solution? I've googled myself stoopid on this one...
Cheers,
PF.

Try to toggle airplane mode on then off..not sure if it will work on our tabs...but it works on my epic 4g touch..this is just a work around though.
What stock did you return to...
I'll look around and see what I can find...
My first thought was it's a router issue. I've had the same thing happen to me and in the end all that was needed was a router reboot.

Thanks for the suggestion. I tried the airplane mode on/off, but it didn't help.
The stock version I'm on is Build number IMM76D.XWMPF (P7510XWMPF_P7510XSAMP1_HOME.tar.md5)... I believe the correct one for my country...? Not sure if that's a red herring, though. The problem occurred going from 4.2 to 4.3 and has stuck with every restore and rebuild I've tried since.

Tried the router reboot, no dice. Also tried connecting to different WAPs and the problem remains. I tried connecting to my SGS4 as a portable hotspot, which was working fine previously...identical problem...

Wifi not connecting on Asus Memo pad 10.1

My tablet will not connect to ANY WiFi network anymore. Everything was working perfectly, but had to send the tablet to Asus for RMA because it would not charge anymore. But now, when i connect to my wifi network it just says its saved and does not connect" I figured maybe it was an issue with my network, so I went out and tested it with other WiFi connections. It can scan and detect everything, but the same thing happens while trying to connect to anything. My Sony phone and laptop are able to connect to everything perfectly, but the tablet will not, even to the networks which it has previously connected to.
Things I have tried:
Deleted all networks by using the "Forget network" option and tried connecting again.
Tried "open" type networks without any passwords.
Rebooted the tablet several times.
Done a factory reset, twice.
Tried to analyse logcat data.
Anyone else know a fixs for this problem? Or do i have to rma it again..

Nobody ?
Same issue - any resolution?
I purchased two refurbished ASUS MeMO Pad Smart 10.1" tablets from Groupon - $109 each - in late Sept 2014. Figured it was a good deal so I jumped on it: I would have one for myself and one for a gift (for my father). Mine has worked without any issues, but I finally gave my father his tablet today (Mar 1, 2015 - yes, six months later) ... and I cannot get his tablet to connect via wi-fi. I've tried all the same steps - from the initial setup to trying other wi-fi locations to doing a factory reset. Nothing is working.
How can I fix this???? Please help!!
I just had the same problem reinstalling the stock rom.
It was a permissions problem caused by the su executable blocking che permission change, I solved installing a selfmade custom zip via recovery, ispired by this thread: http://forum.xda-developers.com/android/development/rom-asus-memo-pad-8-me180a-ww-3-1-0-42-t3027620

My system worked for my MemoPad, but I have no idea if it's compatible with your model...
It's a simple script who changes the permissions, it doesn't install anything, so I don't think it could do any damage...
The problem with original rom was about "set_metadata_recursive" function not existing, so I had to list all files from the directories and call "set_metadata" on each one.

[Q] Galaxy S III i9305 Wifi Problem

Good day,
I have a samsung galaxy s3 i9305 LTE and I have been using this device without problems for around 2 years now. It runs on Jellybean 4.3 baseband version i9305zhucnb1. It has been running on this firmware for a couple months now ever since it has been rolled out. The problem is, the WIFI suddenly stopped working. Never had this problem before and I actually never had any problems with this device ever. Whenever I turn on WIFI, it detects my home networks and other networks wherever I go but whenever I try to connect, it just shows saved secured, and sometimes authentication error after a couple of attempts. I have other WIFI devices at home and all are working perfectly. I tried forgetting the networks and I am positive that the WIFI password is correct. I tried to restore the device to facroty settings hoping that it would work. I tried accessing my router and I'm sure my device isn;t blocked. I even configured my routers to only accept the mac address of my device and block all others but still wouldn't connect. I tried rooting my device via odin but my device blocks root access and shows the error message "an application attempted to access system on your device without authorization. this attempt has been blocked.". I tried rooting it to try flashing custom roms. I also tried dialling *#0011# to configure my wifi but it still does not work. I don't think that the problem is my firmware because I had it for months and it didn't update before the issue occured. I was also about to try downgrading it to an ICS stock rom since I can't root it to try custom ROMs. I've been trying to fix this for days now. Can you guys give me a step by step instruction on how to fix this if it is at all possible? And maybe give me a link where I can download ICS or lower stock ROM's for this device. I think I have to use a TGY firmware, though I don't have an idea what it means. Thanks!
Wifi module
Maybe you've dropped your phone and the WIFI module loosened, and it can't work correctl?

Maybe it's time for factory reset? I know that's the easy solution and most complicated but you should do it from time to time.

i decided to have it checked by a local technician and according to them, this was still a software issue. i dont know what to do anymore. they insisted that i should just keep flashing stock roms to fix these. already tried flashing the 4.3 tgy jellybean stock rom so i was thinking of flashing other version stocks. can anyone give e a good link where i can download tgy stock roms 4.1.2 or even ICS stock roms. I also am having problems with rooting the device. it gives me error message "an application attempted to access system on your device without authorization. this attempt has been blocked." after flashing autoroot in odin. my knox is not installed. thanks.

the first time i brought this to them is when i attempted to flash an incompatible firmware. they also did not fix it. they said they dont have any available stock rom for i9305 and told me to download and flash one. mayba im just gonna have to look for a different technician when i have free time. so for the mean time, im trying to look for other fixes. btw, i tried downloading a tgy 4.1.2 stock rom and it does not flash successfully. for now i'm thinking of rooting and flashing custom roms. but whenever i flash auto root. it gives me the error message "an application attempted to access system on your device without authorization. this attempt has been blocked.". i tried updating supersu still the same thing. i manually installed root checker and says it does not have root access and it shows the said error message again. what should i do with that? Thanks
