[Q] WIFI connects but no internet?

Today I updated my ROM from LeeDroid v2.5 to v3.0.8.2. I wiped my phone first. After this I rebooted, then rebooted again into recovery and installed the recommended radio (32.56.00.32U_5.17.05.08). Then I restored my apps+dat with Titanium back up and rebooted again.
It soon became apparent that whilst mobile internet was working fine, WIFI wasn't. While my phone will connect to the router it won't connect to the internet. If I enter the local IP of my router I can browse the settings fine. I tried "forgetting" the network and re-entering security code but this still didn't work.
I restored my v2.5 nandroid backup and the internet worked fine, the radio is still 32.56.00.32U_5.17.05.08.
So I did a fresh install of the v3.0.8.2 ROM and tried connecting to WIFI again and again the same problem.
So my question is, is this an inherent problem with the ROM, and if so why does no one else seem to have this problem, or is it a setting issue?
Any help would be much appreciated.
Also I tried changing the WIFI channel as suggested in another WIFI thread, and this didn't change anything. Except the WIFI channel obviously.
And I tried a static IP address and that didn't work either.

You try turning off router and putting back on again? I sometime's get that in my network.

Yes I tried turning my router off for a couple of minutes then switching it back on. Didn't change anything.

Did you sort it?

I think you need to wait before the router give your router assign an ip for your phone, btw, some router donot fit all phone model

Yes thanks I managed to sort it today by following this thread
Apparently the fault is inherent to Android 2.3.3 and seems to present itself mainly with Thompson routers. It was a static IP I needed, I'd not entered the details properly the first time.
Thanks for the replies!

Thats good

[solved for now]

My phone says obtaining IP address, and doesn't do anything past that. I've tried on multiple networks, and I've made sure DCHP is on. I've also tried reserving an IP, and that hasn't worked either. I haven't changed anything in a while, it just stopped working this week. I'm running the latest ACS rom. I just flashed another rom and it works now, so it's not a radio or radio firmware issue.

[Q] Obtaining ip...

Hello!
I've been searching for a long time about this issue but I haven't found aan answer...
I have a rooted GN with original rom and recovery. Yesterday I wiped the phone and now I'm not able to connect to any wifi network.
The phone is always "obtaining ip...". And that's all.
I also have a Nexus S and one computer connected to my wifi and they are working fine.
I also tried to connect to another wifi and the result was the same..
Before yesterday I had no problem, even with the phone rooted.
My android version is 4.2.2.
I tried to reset my router (Netgear), tried all security options (open, wep, wap2, etc).
I have no mac filter... I think I already tried all the "logic" options but I always get the same
I start thinking the problem can be android 4.2but I don't know what is whatt I'm doing wrong.
Thank in advance for any help!
Best regards

Flash a factory build to your device to isolate it as software related.

I had a similar issue with a tplink router, now i have a asus and the issues are gone.

I downgraded to android 4.1 build factory and works. thanks

That's an odd problem.
You already downgraded, so there is no scope for trouble shooting.

WiFi not turning on?

Ok so a couple of days ago I installed a 4.0 ready radio on my galaxy s2 and then went on to install Jedi Knight 6 ROM (4.0.4 and radio is UVMC6) and after installation everything was working fine.. I was messing around for a while.. it worked today, I shut my phone off to charge it up real quick, and when I turned it back on my WiFi would not connect. Well not necessarly connect.. it just wont even turn on. When I go into settings and click WiFi, it just sits there saying, Turning WiFi on, and never changes.. I can't seem to imagine what could have happened to it, and I really dont wanna have to reinstall the ROM again because i just spent hours getting this one all set up to my liking...
Anyone got any ideas?
EDIT: BTW, I have tried many things.. Tried airplane mode to disable everything then turn it back on, obviously tried rebooting the phone, i have tried wiping cache in CWM recovery and also tried fix permissions in recovery (another topic said to try those..)
Nothing has worked so far, i'm about to try reflashing my radio, see if that works.. but I really really dont want to have to reflash my whole ROM.. So if anyone has any other ideas please help, i'll edit if the radio works..
EDIT 2: Reflashing the radio did nothing.. it's really wierd, the data, bt, gps.. all of it works fine, it's just the WiFi that's frozen turning on... cant get it to stop turning on and can't get it to actually turn on..
EDIT Final: Ok well, i guess nobody knows what might have been going on.. so I just wound up reflashing my ROM, which obviously fixed it.. i just had to lose all that time spent setting everything up... But oh well.. Kinda sucks nobody even tried to help..

+1 I'm going through the same thing now

I have been having this same issue as well. It started out as stock happening sporadically. One thread suggested rooting and removing my account. Problem still occurring. Tried flashing multiple ROMs and now WiFi hasn't connected at all always stuck at turning on. I have tried clear cache, fix permissions, as well as reinstalling ROM dirty and with factory reset. I'm hoping this isn't hardware failure because I just bought this phone used but it seems to be a reoccurring problem with others as well. Any NEW suggestions not given from quick Google/xda search?

I'd suggest to check your Wireless Access Point (modem or router) wireless settings for security, check and see if it's set to use WPA/WPA2, which is common on some modems/routers, change it to either WPA or WPA2 (preferred) not both, it's a known issue with WiFi networks and having it set to using both, I had the same problem before with my phone connecting to my WiFi.
Also if you use MAC Address Filtering on the modem/router, you should disable/clear that and let phone re-connect before enabling mac filtering again.

The problem I am having is not that it won't connect to a particular network. Wifi will not initialize on the device at all and is stuck in "Turning On..." state. I found more and more posts where people ended up having to send in to Samsung so I spoke with them and even though I purchased the phone used its thankfully still under warranty and they will be replacing it. The did not confirm whether or not it was a true known device issue but were quick to file the exchange for me.

sigh, me too!
Just started having this problem on 4.3.1
great.

In my case, I had to wipe system and data before reinstalling my ROM.
Though the only reason it was happening to me was because Beanstalk 4.4.2 didn't want to get past the splash screen when I tried to install it so I downgraded back to ICS 4.0.4 without wiping. Good luck getting this issue fixed. Also another kernel might fix thingz for you if your current one does not like your device.

I have a similar problem. After a while, WiFi gets disconnected. If I go in settings - wifi, i get the message "unfortunately, settings has stopped" and I can't get WiFi to work again until I reboot the phone. The Wifi works again for a couple of minutes then stops.
I have flashed various different ROM (CM11, PA) but keeps getting the exact same behavior.
I've rebooted in safe mode and I don't get the problem now.

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.
