Wifi stuck at "obtaining IP address" - Stock LPY

I am on rooted stock LPY. I noticed that whenever I try to connect to wifi it says connecting then stuck at obtaining ip address and then disconnected. I have tried more than one router and I am getting the same results. I have googled this and one solution is to have a static ip address. The problem is that this setting is no longer available in ICS. Any idea how to fix this without wiping (I am too afraid to wipe given all the fuss about it).

Did you flash the LPY Rom with or without full wipe? That might be the cause.
You can flash a new modem and see if it's fixed. I can't think of anything else...

Experiment with frequency band under advanced wifi settings.

When i was on ICS i had the same issue.
This is what made it work for me:
- remove network from device, disable wifi and turn off device
- turn off internet modem(if you have any) and router, wait at least 2 min.
- turn on modem and router
- turn on device, enable wifi and connect to network
Hope it works out for you

With wifi disabled, if you have root, go to /data/misc/dhcp/ and delete all 3 files there.
I had problems on LPY where wifi would connect but ip address wouldn't get assigned.
Deleting the 3 files in /data/misc/dhcp/ fixed it for me. No probs since

Re-flash with wifi off, make the sincronization with google on 3g and then turn on wi-fi connection

Deleted the files as you suggested ( I had 4 instead of 3 ???) and still no luck. Thanks anyway

I gathered all my courage and flashed a pre rooted GBrom via pc Odin, no wipes, no cleaning, no nothing . once back on GB i only performed one hard reset and felt confident enough to flash CWM back on it. I would give you the link, but am on my phone right now and can't find it, but the rom is in Bodivas thread around here.
It worked out well for me, but as you probably know...no garantuees.
Btw, sorry to see your wifi still not working

Hmm. Those 3/4 files should get recreated if DHCP is working properly on your phone.
Perhaps you phone is missing stuff in /system/etc/dhcpcd/?
Another thing just popped into my mind - did you restore your Wifi Access point details via Titanium Backup? I think that may have been an issue for me too on LPY... don't restore is best.
Or just downgrade to GB, full wipe and flash LPF

Do you have soundhound or dolphin browser hd installed?

I'm on LPY too. When I'm at office I have no issues with wifi connection but when I'm back home I start to have issues. It shows connected and I get no error or disconnected messages what so ever. But device looses wifi connection short time after connected. I check wifi connection on laptop and there is no problem but on my Note even though it shows connected I have no connection. Turning wifi off/on fixes it sometimes but most if the time it doesn't.

Just flashed / rooted ZSLPF ICS following Dr. Ketan's guide and now I have wifi again . Having read so many posts about this, it would appear that the wifi issue has something to do with the CF-Root kerenal. Thanks buddy

That maybe is ROM issue! Just revert back to stock ROM using odin.

I just saw this post and thought I shoud help him even after two years passed.

Go to Settings >> Wireless and Networks >> Turn on WiFi
Long press on connected network >> Modify Network >> IP Settings>> Menu >> Static
Assign your IP address and leave other credentials as they are. Save settings and you are done.

WiFi problem

I was recently given a Galaxy Ace as I bricked my LG P920! When I connect it to my home Wifi, it works when for a few mins then puts the phone into a reboot loop and only stops when I disconnect the wifi. The phone seems to work fine at all other times including when on 3G. It's not the wifi as it works fine on the wife's HTC Incredible S. Phone has not been rooted. Does anyone have this issue or know how to resolve?
Thanks

I suggest rebooting into cwn and clear cache and then try again.

No luck with that, problem keeps re-occurring.

Flash Stock
Try Flashing Stock firmware with odin!

I guess you have stock.
There is a random wifi problem in stock which sometimes reboots the phone because the wifi driver breaks.
So try CyanogenMod and there wont be any problems!
Dont worry about rooting.
You wont brick your phone.
Only way to completely brick an Ace is to use Rom manager. So just dont use it!

Check for a software update on your phone. IT fixed The problem for me.
If that doesnt help set your wifi connection up with a static(?) Ip adres on your phone. Worked for me as well.
Sorry for my english
Good luck!

What version of android is installed? Best way to do an Official update is via Kies. If you get the same issue with kies as I have (Crashes on startup) use Odin or install a custom rom via CWM.
Also try changing the WiFi channel via your routers settings. (you never know, might work)

Trouble on wifi. Will this fix it?

Hi. So, I just got a Samsung S3 GT-I9305 from Vodacom. Got it from eBay. But, I'm having trouble connecting to the wifi. Whenever I connect to the wifi it always says "Authentication error occurred". I turned off the wifi thingy using *#0011# and wiped the cache, I even reset the phone to its factory settings. I sometimes connect to a wifi, but it takes 1 hour or so before being connected. And I have trouble downloading from the playstore. Did everything I could find from the web. No luck.
So, I was thinking, If I would flash a custom rom to my device, will it fix the wifi issue? And would any stock firmware of the I9305 device work?
Thanks! Sorry for being noob.

Hi,
I think it could be a router issue. You should :
- reset your router and retry to connect with your i9305,
- play with WIFI network settings in router. Maybe something doesn't allow your i9305 connection (network type, firewall, etc.). I'm not an expert in router settings, so you could google this to help you.
- try another WIFI network (from a friend, at work, anywhere you can test )
I think that flashing a custom ROM won't change anything. First try to fix your problem with stock firmware.

[HELP] Wi-Fi problem after mm update- SM_9208

My note 5 is the duos version, imported in Romania from Taiwan (SM_9208) After updating to Marshmallow yesterday, everything worked fine except for on thing: it doesn't find my Wi-Fi network from home anymore and the only way I can connect to it is by going to,, add network " and manually inserting the ssid and PASSWORD because it doesn't appear on the available networks list. Thst means that every time I turn my wireless off and then on, I have to repeat that process.
I haven't had the chance to try any other WiFi network, but I tried with other phones to connect to the network and they found it and connected to it without any problem. Furthermore, any third party app like WiFi analyser is able to see the network.
Do you guys have any idea how I could possibly solve this?
Thank you and have a wonderful day!

Try to backup your phone and then do a factory reset.

I factory reset after update OTA and everything work perfect.

uhm... does n9208 has update for MM already? if you have links kindly share tnx in advance

I tried doing the factory reset and it still has that problem.
And I did receive the update yesterday through OTA.
Other suggestions? Thank you, guys!

First, try clearing the cache again. If it still does not work, the update may have downloaded improperly so some file are corrupted. It will continue to use the same corrupted files even if you reset. Have your tried flashing the stock Taiwan Rom using Odin?

//LATER EDIT: I finally made it work by simply changing the wireless network's name. For some reason, my phone wouldn't find the network with its default name.

XT1925-4 wifi problem please help

Hello guys im new here and i tried lot of things to repair my wfi problem.
So its my mom phone and one day she called me about selfrestart phone in night and there was image of bootloader and startup failed.
So after classic factory reset and etc my wifi still not working. The problem is i cant connect to any wifi. I can scan it but wont connect just say disabled or saved but not connection.
After this i tried flash stockroom succesfully after 2 days of hard work So i flash stock room but the problem is still there so im not sure what can i do anymore. If i can try flash some newer rom or custom rom or its just hardware failure? has anyone have problem like this? All others things work normal like data connections etc. Sorry for my english
1. update so i flashed another lineage room just in case and still not working.
2. i notice in system information that wifi mac adress is 0d:00:00:00:00:00 so can be hardware failure probably.
3. Hotspot wifi is working so i can connect from another mobile to the broken wifi mobile
