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

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.

Finally ... wifi working as it should

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

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.

[Q] WiFi Won't Connect GDX028b

Hey, I've got a problem after a fresh install of GDX 028b.
My WiFi simply won't connect. It sees the avaliable networks, but when I try to connect to my router it stucks at connecting, at disconnects, then goes back to scanning, doing this cycle forever.
I have an Alfs v08 and GDX v028b, and I've installed the GingerDX Alfs Kernel AddOn v007 as well.
What can cause this problem?

Things I've already done:
-deteled the remembered networks
-completely wiped everything, reinstalled rom, kernel

There's a kind of fix Swift did with titanium. it worked for me even on v28. You may want to search that.

its so simple..and work at my phone

Thanks for the reply, but unfortunately this did not work.

Sorry, but I have to bump this.

One last update, I've obviously tried to connect to more networks, some open, some closed, but I still couldn't manage to connect.

I've got my phone like that yesterday...
and Im trying to flash all kernel and ROM
and now the wifi and mobile network is working normally :laugh::laugh:

try this !!
I had the same pribleme before i used this rom
http://forum.xda-developers.com/showthread.php?t=1507021:good:
thanks please :good:

Still cannot connect. Tried out several other roms, all of them are working fine, but not this. However, this is the best rom out there in my opinion. What to do?

Networks detected but will not register

So I had some escapades today, I had my SGS running jellybean, then I tried to change the screen density and bang, bootloop. I panicked and after some odin fiddling managed to get it booting Darky using odin. I was in a room with no signal at the time so I thought nothing of not having any signal, even so I then went ahead and used recovery to reinstall my Jellybean rom since that's a bit nicer than the 2.3 Darky.
Long and the short of it is, I can search for networks in my options and it will find them, but when I tell it to connect to one it says "Can't connect to this network right now. Try again later"
I have tried later and surprise surprise it didn't work. I have tried installing a different radio, clearing the dvalik cache and fixing permissions as well as a few other things. Please can anyone suggest something, this seems to be a very uncommon scenario and it's stressing me out that I can't find any solutions.

Yeah I've checked them and unfortunately they all seem to be in order still, though there are a lot more settings than any website offers things to put in them

same problem
i am having this same problem on all cyanogenmod 7,9,10. i have tried many radio and modem flashes. i can scan and see networks, but i can never connect to them.
have you made any progress?

Problem is EFS folder which tends to do with IMEI.
To fix it you need to copy the backup EFS folder from your SDCARD to the root of your device. (/)
If you don't have a backup you'll have to ODIN back to stock and re-root....etcetera

thx
thank you for the response. I put it back to stock lastnight before bed so i will give this a try.
i have the gti9000m from bell in canada. I updated it through kies to 2.3.3 gingerbread and it all went badly. It would boot up and load to the os be on for a bit then reset. It turned out to be wifi problem, running it on airplane mode stopped it from rebooting. Then if i tried to turn on wifi it would quickly reboot.
So then i tired all the cyanogenmods, which worked it stopped rebooting all the time. however the wifi would connect and work for about a minute then it would drop. doing the
1.turnOn gps
2.turnOn wifi
3. turnOff gps
this would let the wifi work again for about a minute. I tried all the wifi fixer apk, and a bunch of wifi.zip mods, and then ping the router gateway constantly, none solved this problem. Very annoying because i need the wifi working for develpoment of apps. I have spent a great many hours on this problem. lots of people seam to have this problem but no solutions have wokred for me.
So, my questions are....
1. does your wifi work?
2. how the heck do i get mine to work?

back to stock
After going back to stock then upgrading connecting to network operators is fine.
wifi is still broken though

[Q] Weird wifi bug

Dear all,
I was previously on GDX v11 stock kernel. Working great.
Then, suddenly, the Wifi stopped working. Didn't change anything at all in the phone, nor in my home router.
It would keep scanning, connecting, disconnected, stuck in this loop.
I'm not sure this is connected, but the battery looks swollen too.
I tried removing forgetting all networks, and rescanning, did not work.
Then, I tried connecting to open network, still no luck.
Tried with different networks too.
Fresh wipe, clear cache, clear dalvik cache, same problem.
Then I installed v031b stock kernel using xrecovery in v011, but sadly, no wifi too. As an aside, v031b is just awesome! Super smooth with great functionality.
Any ideas guys? Or is it a busted wifi chip?
Thank you.

How many times do you need to post this? Flash back to stock rom. I'll report you if I see you doing this again buddy!

Sorry, I already deleted the earlier thread before moving it here.... Thought it would be more appropiate here. My apologies.

It's ok mate.. Just keeps the place tidy!
Good luck flashing back!

The 3G works fine on pac?
However, you can try to flash the boot.img in fastboot and see.
And, what's your problem with the recovery?

I am having the same problem too. Was previously on trickdroid. Flashed Revolt ROM and my wifi wasnt connecting to my home network. It could detect, prompted for the network password but after that it just wouldnt connect. So i looked deeper in the phone's information and discovered that my phone's IP address was in a different IP address range. It was 10.x.x.x and my home router was 192.x.x.x. My sister's S4 had no wifi problems (unrooted) and hers was 192.x.x.x. So now I'm trying to set my HTC One's IP address to 192.x.x.x. Still trying to figure a way out though. Hopefully it will work. Give it a try!
