[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.

[Q] [ HELP ] Connected to the Wifi network but internet working very very slow

hi guys.
I have got a new wifi connection installed at my home...i was on Omega Rom when i first faced this problem.As soon as i got my connection installed,i tried connecting my Note 2 N7100 to the network, it connected but the surfing was slow as if like no connection whereas all my other devices like laptop, Ipad and my bros. I phone is working smoothly on the same network.
I tried surfing on my office wifi network and it worked flawlessly.
Frist i thought that may be its some kind of bug which is their in the ROM so i switch to Alliance Rom V3 .....i did factory reset..wipe cache and dalvich cache and sadly still having the same problem.
Any ideas...?

8.4 Tab S Forgets WiFi Networks On Reboot

I'm on stock, rooted odex. I believe the issue happened after I rooted. On boot, it forgets all previously connected WiFi networks. The only mods I've flashed was the 4-way boot (which didn't work since I have CWM and not TWRP). I've tried deleting the dhcp files in the dhcp folder and the wpa files in the etc/wifi folder. Neither worked.
Anyone else having this issue?
Edit: Factory wipe didn't rectify the issue. Guess I'll ODIN back to stock. Hopefully this is a hardware issue.

Strange.....mine works fine, rebooted numerous times.

Figured out the issue. I mistakenly flashed the T800 autoroot instead of the T700 autoroot.

Hi
I am stepping in on this thread, because I encounter this issue.
I just rooted by Galaxy Tab S 8.4 (LTE) - T705 and I followed this site http://theunlockr.com/2014/08/09/how-to-root-the-samsung-galaxy-tab-s-8-4-lte/, used as instructed CF_AutoRoot_Port_T700_BeansTown106.tar with Odin3 v1.85 .
- when rebooted the wifi forgets the password, (as long as you dont reboot the wifi is okay, and i can connect to other network and connect back to the original wifi.)
Do anybody knows how to fix this issue?

I think you have to change some sort of file to something to make it remeber it. I cant remeber what the fix was but it was somewhere in the cfautoroot fourm.

HI,
Consider also using Skyhigh Kernel, it fixes your issue.

My nonrooted Tab S forgets WiFi on reboot and when I switch WiFi off and then on.
I found that this probably is a KitKat bug (http://forum.xda-developers.com/showthread.php?t=2685519)

If you are rooted then this is what fixed it for me.

Unfortunately I have no root, so I flashed the newest firmware (T705XXU1ANH1 – XEH from France) and it fixed Wi-Fi

So, I using mine tab with and 6 on the latest image from Brazil.
It is rooted and with TWRP.
It doesn't save wifi networks. If I turn wifi on and of it looses everything.
Just to be clear, it had this problem before I installed TWRP. It took me quite some time to notice the problem so I don't know if it is related with the root method.
I even flashed a custom kernel, but still no luck.
Does any one know of a solution for this issue on Android 6? Stok?
Thanks

Note 2 WIFI not turning on (ND3 Bootloader)

I am having issues with turning on WIFI in my Rooted Galaxy Note 2 GT-N7100.
Background: After facing various slow down and WiFi drop issues with my Stock 4.3 ROM decided to Root and install custom ROM. Rooted and Installed C-ROM 7.1 on device. Everything was working fine initially but after few days WIFI signals just drop and after that it just wont start. Again flashed and installed DN3 V5.2 LIte ROM,
Problem: Still WIFI wont start, it starts sometime after reboot but keeps scanning and can not detect any WiFi signal and after few minutes it wont start at all.
Solution Tried:
1. Tried Dr. Ketan WIFI Fix multiple times, still no solution
2. Can not downgrade Bootloader to MJ5 because its already on ND3.
3. Tried multiple modems (ND1, ND2 and ND3), no help, getting strong 3G signal but WiFi just wont start.
Current Phone Config:
Device: Samsung Galaxy Note || GT-N7100
Android: 4.4.2
Boot Loader Version: N7100XXUFND3
Kernel: Linux
Kernel Version: 3.0.31DN3
I am not an expert, so please pardon if my question is not clear. Any help will be appreciated. I am OK if i have to unroot or complete wipe my device.

Hardware Problem!?
Looks like something is wired with phone WiFi hardware. After flashing ND2 modem WiFi actually started to work, but stays connected only when signal strength is very high, as soon as signal goes low it drops the connection and never connects again until and unless I reboot the device or go to Airplane mode and come back.
Any suggestion in this regard is welcome otherwise I have accepted this problem as Hardware problem rather then software problem and going to live with it till the time get some good deal for the device.

Exact same problem. but no solution so far.

Just an update, I've followed some comments below the video and now my wifi works like a charm.
It seems that the note II housing was the cause, hope it might help you too.

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.

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

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.
