I got problem with my gio, when i tried to connect to wi-fi.. when i connected suddenly the wireless and network force close, and disconnected from wifi..
anyone have solution about my problem?? i've tried in stock rom n stil got the same problem

What rom are you using ?
I have wifi problems too, when I leave it on and stop using the phone.
I am using 2.3.5 Baseband S5660XXKS2. From what i've read in another topic this one has a baseband bug.
Switching to S5660XXKS5 should help I heard.
I haven't tried it yet because I'm having trouble with backup up my rom with CWM (5.0.2.7 signed_cwm-5.0.2.7-flashablezip-ext4+rfs.zip) .

i've tried CM 7.2, MIUI from delanoister, stock dxkt4, and bnc-r2 and still can't connect.. i'll try to flash to xxks5, hope it works thx

wifi works well now, i think the problem comes from the server setting that caused my hh got force close when connected to the wifi

what's hh ??
I flashed the suggested rom today, and it seems (fingers crossed) the reboots have vanished. I have WiFi on since 12:30 and no reboots !

I have bene using GB roms but never faced this issue. Today, I tried first Nikez lente JB and K900 AKOP ICS. I couldn't connect to wifi.
When I click on turn on wifi, the message appear turning Wi-Fi on .. but nothing happened. No Icon shows in status bar for signals of wifi either.
I am on Stock Hboot PVT4 S - OFF

Hi, you have to go into Settings and the click on Wi-Fi for a few seconds and let go. It will bring you into the next menu where you can choose the network you would like to connect to.
Once you find your Wi-Fi network, simply click on the name and enter in the password (if it has any).
I just switched over from a stable Gingerbread version of MIUI to this Jelly Bean rom and I like it so far.

Thank you for your answer. I tried every method to turn on the wifi. But it not seems to working. It is not turning on. I tried to find this answer on google and as well as XDA but I didn't find any answer to this question. I think this wifi issue is occurring on PVT4 devices but not sure what could be the possible reason for it.
Now, I think I should stay on GB and I am installing Leedroid. Let's see if this error still exist.

Strange, it resolved the wifi problem. I flashed the rom and removed the SD card and the wifi is properly working. I didn't figured it out how to manually add IP address. Just like in GB roms we have advance settings in wifi menu. In ICS there wasn't any advance settings.

[Q] TMO SGH-T989 wifi not working. is this h/w issue?

I bought this phone used from eBay and it worked fine for about a month.
Then the Wi-Fi stopped working. as you can see in the pictures, the wifi button (slider) is disabled/grayed out and if you go into the menu, it is stuck on "Turning wi-fi on".
I've tried everything from downgrading to 2.3.6 GB (currently on official ICS 4.0.4 through Kies) to installing Cyanogen mod ROM but it wont work. rooted then unrooted. everything else works great.
Any help would be appreciated.
I've attached screen shots to this post.
Thanks.

Did you powercycle modem and then router?

Yup. I did. I have other devices on home wifi that have no problems connecting. In addition i have tried at starbucks and work wifi. Still no go.
The WiFi on the Galaxy S2 wont even turn on to recognize/select networks (SSIDs) to connect to. As you can see in the pics, the Wifi ON/OFF button is grayed out/disabled.

Did you try flashing a different radio since the issue started? If not I would try it, maybe downgrade the radio to UVLI1 or even try re-flashing the same radio. I know I had this issue once before but fixed it somehow, I think it was just a reboot for me but if you tried all of what you said in the OP you would have rebooted a few times.

Did you use Odin to flash back to stock? If not, give it a try with a full wipe.

Although i have not tried to mess with Radio (noob here, not sure i wont mess that up), I did Odin the phone back to stock ROM with no luck.

When you flash a stock rom in Odin, it also flashes the radio.

Ah Ok. There you go then. and i tried with a couple of TMO stock ROMS (starting with GB 2.3.6). so obviously that hasnt worked. Thanks.

i found a possible fix, that worked for me. Go into your recovery, i did it with TWRP (latest one) and advanced and fix permissions, than i rebooted and worked! Give it a try.

To avoid any future hassles I contacted the seller and he agreed to take it back for a full refund, so i guess i'll never know what happened. Thanks for your help everyone.

I know this thread is nearly a year old, but I had this problem and figured out a fix that worked for me so I know its still relevant.
My fix was:
- reboot into latest cwm recovery (v6.0.4.3 touch for me)
- click "mounts and storage"
-click "unmount /cache"
-reboot
So far it has worked every time and wifi screw ups have happened rarely ever since. Hope this late post helps at least one person who was as frustrated as me!

My WIFI is off, and if I hit turn on, it got stuck on turn on. But if I were to back out and go back in, it would be on off again.
I'm using Kitkat
After awhile all i had to do to fix it was turn airplane mode on and off. But just the other day, I was flying so had my phone in airplane mode and now that won't fix it and neither will my original fix :crying:

I have the same problem
It was working fine stopped and did everything and still not working,

Wifi trouble (staying connected) Stock Rom 4.1.1

I had downgraded back to Stock ROM 4.1.1 everything was fine.
But the WiFi is very sketchy. It stops or times out or something all the time. I can't seem to keep the wifi on.
Is there a workaround for this. I tried the trick of *#0011# and turn the wifi power save off but it doesn't stay off after a reboot it comes right back on. So I am not sure what I am doing wrong. Any ideas?

Might need to update your wifi drivers.
Also could be coming from your router.

Do you know where I can get the wifi drivers? Or is it in a Kernel or something?

updated kernel would probably fix your issue. If it doesn't though, chances are that it's coming from your router or your router's settings.

I checked my router and its working fine. There is no problems with it. I am a computer technician. So I know there isn't anything wrong with it.
I have tried several kernels and they are all doing the same thing. I'm afraid I will just have to go back to an AOSP rom or something. I didn't have problems with them...

WIFI will not turn on

Hi guys i have a lg g3 that has been running fine on kitkat
it the received the lollipop update OTA and all went fine apart from now it wont turn the WiFi on
you can click it on and it moves to on but seems to be always trying to turn on..?? without turning on.?
any ideas..?
I have done a reset etc still no joy

Did you try to reflash? (I think that you mean by resetting that you full wiped your phone and not reflashed the rom)

Same issue here.
I get around it by forgetting network then just signing in again. Wifi works perfectly until I leave the house and return later. Then I just do the above and viola, working wifi.
I've checked with speed test app and wifi is definitely working.
Funny thing is, if I switch off wifi then turn back on it also works.
Only when ive left home and returned later does this bug arise.

Hello guys,
This thread is a little bit old, but I am curious to know if you found a workaround for this issue.
I have the same problem as the OP (not at the second poster): since I received Stock Lollipop the WiFi won't turn on. When I try to, it says "turning on" for a while then acts like it is off.
I just bought my LG G3, NCIX the reseller, refuses to refund me or replace my phone...
I performed several factory resets and tried to flash different KK stock Roms. The weird thing is that the WiFi works with KK...
Thanks for your help.

Identical experience here.
I recently got a D855 16GB, which was on stock unbranded V10a, jumped through several OTA updates through V10g, V10j, and V10k (IIRC) all with wifi working fine before getting the lollipop upgrade OTA for V20c.
Immediately wifi will not switch on - the switch itself is on, but with the off section a lighter grey compared to the bluetooth switch.
On the wifi screen itself it says "Turning Wi-Fi on..." but after a while the switch reverts to off.
It's now had OTAs to V20e and V20h, but wifi is dead on both versions.
Note that this is stock and unrooted (never rooted) so I can't believe it's something I've done. Next trick will be to root and poke around /data/misc/wifi.

Does bluetooth work or the problem is only with the wifi? I also have the same problem, wifi, bluetooth is not working and when I check in the settings the mac adress it says "unknown".

Accountability
Unfortunately this isn't a unique problem. There have been countless bad updates from multiple manufacturers. In this litigious world, I'm surprised no one has sought damages for bad updates that effect usability.

I have the same problem from yesterday. wifi and bluetooth seem to be turning on but they never turn on. i've done many factory resets but it didn't work. has someone found a solution?

^^^ Exactly the same issue. Would love a solution!
Same issue. Tried Hard and soft reset and have also updated firmware using LG Mobile Support Tool but had no success.

ok, after 24h with this problem I think I got it back to working. Let me explain what have I done:
1. Mine is a dual sim model, that I bought in hong kong by the end of 2014.
2. Yesterday, I removed sim #2 (no longer needed), without removing the battery. I had a couple of messages indicating to restart the phone, blah blah. Can't remember if I finally restarted it or not.
3. This morning I saw no wifi connection in my phone, only 3G. Tried to start wifi in the quick access menu, but this kept blinking, never starting wifi. Restarting phone... nothing. turning off bluetooth... nothing.
I figured out that the problem had to be related with the SIM as this is the last thing I had done with the phone. Thus, I tried this, with success:
4. I turned off the phone, changed sim from slot #1 to slot#2 and started the phone. Wow, it worked for some minutes, then stopped, then started again. Well, a good sign.
5. Changed again sim from slot #2 to slot #1: Wifi working again. After some time it stopped working, but soon started again. Hasn't given me more problems (after only 30 min, that's true).
Hope it helps.

I have exactly the same problem and I think we're not the only...
D855 :
-Wifi and Bluetooth doesn't work.
-Wifi keep turning on itself and the battery drain..
-3g/4g works perfectly.
-Downgraded on kk and Wi-Fi works so it is not a hardware issue
-Even on fulmics Rom Wi-Fi and Bluetooth doesn't work
HEELP ME PLEASE

Got the same problem here. I have my G3 since november 2014 and recently I rooted it to install CM 13 on it and Xposed bcs I got tired of the laggy software of LG. One morning I woke up to drink some water and saw my phone restarting a lot of time... ok I thought its a simple bootloop. Tried to install CM again, didnt fix it. Flashed stock software and still... Bought new battery and new power flex and the problem is still there. I go into download mode, installed the software with LGs support tool and got pass the bootloop, but now wifi nor bluetooth works. I thought it's the software so I dared myself again to root it and installed TWRP and CM13, but it wouldn't boot. I installed then Liquidsmooth, based on CM13, and got it to boot up, but in the configuration menu where WiFi is needed to be added it couldn't turn on. I skiped it and in the middle of the process it started again to restart. I don't know if it's a hardware based problem or software... But I would like to try everything out before I have to buy a new phone.

I installed CM13 and in the setup screen I actually had wifi and I could connect to my router. It was kinda strange. But bcs I have some problems beside wifi, the reboot thing, I couldn't test out if it works too. Try flashing CM13 or ROMs that are based on it like Liquidsmooth. Maybe it will help.
