What kind of security is your wifi modem is having? is it wps smthng lk that? Did you tried with different wifi hotspots?
it doesnt have any security, i disable it
The thing is that it doesn even recognize that there is a wifi signal, it just turn off automatically before without detecting any wifi signal, i tried at work and the same thing happened
(sorry if i misspelled a lot of words jejeje)
try to flash another ROM and see if it works...
Sent from my GT-I9100 using XDA premium app
i restored the backup i made with cwm and everything works fine now (touch x-power rom), and if i reinstall check rom the wifi goes out again, it seems it deletes something that leaves me with no wifi mac adress (i searched in about the phone, turning on and of wifi and every time it said not available)
Bizarre...
im getting the same thing, did anyone find a solution?
had this same exact issue.. it is a hardware problem.. so changing rom, kernel or fw wont help you at all... only solution is going to samsung service center.. my problem was solved in 3 days..so many s2 users have this problem..
take a look at these threads...

There are a lot of problems with KK5 and wifi. If you update Busybox it borks it completely. I can't connect to my 5Ghz home wifi but the 2.4 Ghz works fine. I also can't connect to some wifi that uses WEP. All works fine with previous builds. I have seen threads that suggest replacing the wpa_suplicant file from Android 2.3.5 fixes the problem.

Hi there =)
I've a very puzzling problem with my phone ..
it's started two days ago .. I was reading my mail then suddenly the wifi turned off and start again, but it stopped at 'Obtaining IP address...'
I thought maybe it's router problem, so i restart the router but still the same problem .. then I turned off the phone and took off the battery and tried again .. nothing
then I changed the router to another one .. but still the same thing
removed the password from the router, tried IP address,
I tried 3 applications : FXR WiFi fix and rescue, Fix My WiFi, WiFi Fixer
but nothing worked ..
I've root, so I flashed the original kernel, then the last thing I tried is Factory reset
wiped all the data and cashed .. but none of it helped
I'm using the ROM JPKJ2 2.3.5
any suggestions that may help ?!!!
happens to me at times...
do you have more than one router/switch in your house?
Install wifi analyer (or equivalent) and check which channel your router is using..
is there any overlap with say your neighbours router?
try changing the radio channel on your router or it is has a smart channel switching setting enable it.

it's not a router issue .. I went to a friend's house and tried to connect to his router but it's the same thing .. stuck with 'Obtaining IP address...'
my flat-mate also have SGS2 but the wifi works good with him, I also tried the tethering from his phone to mine .. and it didn't work =/
thanks for your reply =)
Flash a different modem not kernel first .
jje
I just flashed the entire rom .. and it worked =D
but still want to know what caused the problem !! =/
thank you guys =)
How weird????
I experienced the same thing last night, in the troubleshooting that I have done, the WiFi would stop connecting after I tried installing the Roboto Font using Font Installer, it first occurred when I upgraded to KK5 from KJ3, I didn't like the font so I went ahead customizing my device to my usual standards then realized that the WiFi was not connecting, it was stuck on Obtaining IP Address.
I decided to factory reset, nothing, so I flashed back to KJ3 and it was working again, I was relieved, so I installed Jkays Mods and also the Roboto font and Speedmod Kernel, woke up in the morning to the WiFi not connecting again, so I flashed KJ3 with Odin and it connected, I flashed CF Root KJ3 and it was still working, I installed Jkays Mods and it was still working and when I installed the font using the app, it stopped working again, so I flashed KJ3 through Odin again, then flashed CF root and it was still working, this time I used font installer to install Roboto font before Jkays Mods and again my Wifi was stuck at obtaining IP address.
So I flashed KJ3 again and it was working, then CF Root and Jkays Mods and all is well so far, but I fear that it can happen again as I have no idea what is really causing it, and I can't make the connection between the app Font Installer installing the Roboto font and my WiFi being borked...
What were you doing exactly before it stopped connecting....
there's something wrong !!!
the first time I had the problem I was just reading an email from my teacher using Gmail, nothing weird ... now after I solved the problem by flashing the rom I start restoring my apps using My Backup Pro, then i restart the phone and the problem return !!!!
there isn't any new app, all the apps was working well without causing ay problem.
so i flashed the rom again without wiping any data .. my apps still there and the problem solved !!!!
Thus far, it seems the issue for me was the Font installer, I still don't think that I am in the clear, so I would use my phone normally, maybe something will reveal itself with patience
I will keep the variables to a minimum, use the phone normally and finish installing all of my apps, if my phone continues to work okay, I will try a custom kernel and so on and so on, it is good to know that the issue goes away when a stock ROM is flashed though, hopefully that will not change

I'm having the exact same problem with Cyanogenmod 7.1.0 stable. I downloaded daily 116 but found that if I just reflashed the 7.1.0 .zip the wifi would start DHCP association negotiation successfully again.
The problem for many seems to be related to updating busybox installer by Stericson
Just flash over the original rom and don't update busybox

it happened again, but this time I only flashed the modem file from the stock ROM and it worked =)
you don't have to flash the entire ROM

I'm on the latest nAa kernel, using MiniCM7-2.1.9, but wifi just doesn't work. I can browse the internet using my 3G connection, just not wifi for some reason.
Wifi shows it's connected, the signal bars is full but it just doesn't download any data, it's like it's not connected at all. It's able to get an IP address and the link speed is good but it just doesn't get any data.....
I've tried searching through different posts and tried solutions such as:
http://forum.xda-developers.com/showpost.php?p=21766413&postcount=498
as well as the instruction to fix wifi in the Troubleshooting page here:
http://code.google.com/p/minicm/wiki/Troubleshooting
and this:
http://forum.xda-developers.com/showpost.php?p=22170822&postcount=817
I also cleaned the dalvik cache by going into recovery, reboot and still doesn't work.
and they all don't work....
UPDATE:
OK nvm it works now. I reflashed the kernel, wipe data & factory reset and then reflash the rom, and now it works. It's the exact same thing I did for the past 30 mins, except this time I also reflashed the kernel. I just hope it'll continue working.....
UPDATE 2:
Ok, now it's not working again. I rebooted the phone twice, and it was able to connect to wifi no problem. But then later on it stopped working again, I didn't install or change anything either.
I also noticed that whenever I'm connected to wifi on my phone, the wifi on my PC will timeout and drop connection. If I then try to connect wifi on my PC, then the wifi on my phone will timeout. Basically, I can't connect both at the same time.
But all my other devices work fine. My Motorola Milestone and my mom's HTC Desire Z works fine. My iPod Touch works fine, I've NEVER had a wifi issue with any of my devices until I tested out my new Xperia X10 Mini Pro today.......
I haven't tried testing it on stock rom & kernel, because the first thing I did was to unlock the bootloader and flash the nAa kernel + MiniCM7-2.1.9. And I can't be bothered flashing back to stock since I won't be staying on stock anyway, especially after setting up everything already so I can't really be bothered.....
Anyway, so I then tried to delete wpa_supplicant.conf in data/misc/wifi (as mentioned above) and this time it shows "Error" under Wi-Fi settings.
This is really annoying me....
One note about wpa_supplicant.conf (/data/misc/wifi/wpa_supplicant.conf). In stock kernel with MiniCM Pro from paul-xxx the right ctrl_interface was wlan0.
nAa kernel (with MiniCM from nAa) needs tiwlan0.
So it isn't necessery to delete file with all wifi networks when changing kernel/ROM but one value in config file.
ya, except the value was tiwlan0 already, I tried changing it back to wlan0 and nothing happens. So then I tried deleting it, and now whenever I try to turn Wifi on it just shows Error.
What's actually strange about this is that I've backed up the original file, and when I restored it and tried to turn Wifi on, it turns on but doesn't display any network.
Before, it would display tons of networks, and it would connect to my router (but doesn't download data for some reason). It doesn't work but at least you can tell it's able to detect networks.
Now, it doesn't even show any networks. The only way to fix this is to restore from recovery or do a wipe......
Ok so I did some research and could this be the case?

I've also tried to assign static IP but it still doesn't work. I went into my router and checked the ARP, and it shows this:
IP address Flags MAC Address Device
192.168.1.2 Complete 00:18E:48:42:C9 br0
192.168.1.3 Complete 00:E0:4C:A3:8B:A8 br0
192.168.1.6 Incomplete 18:87:96:FE:16:3E br0
192.168.1.5 Complete 48:5D:60:3B:5E:5D br0

where 192.168.1.6 is assigned to my phone. I'm not that good with router stuff but know the basics, does anyone know what I need to configure?

HI all
I am not sure if this is just me or this is a bug for the ICS.
I have flashed (do wipe and all that) but my WIFI is not re-connecting.
So I get the WIFI connected first time without issues. then if I turn off my modem and switch it back on, my phone does not want to re-connect. it looks connected but no internet connection. I have switch on and off the wifi but no result.
The only one which will fix it is to reboot my modem again.
I never have this problem with GB.
I have tried LPQ, LPS, LP3 and also LP4 but no sucess. Do I miss something here?
I did a search in the forum but no result on the solution.
Any suggestions on how to fix this?
I don't want to root my phone.
Cheers
I also have this problem. I'm on LP3. No solution for this yet?
Happen to me too before.. and it happen randomly too!
Toggler the wifi few more times..
and/or
Try disable and enable "flight mode"
fix for me..!
Did all that but no luck. I thought it was just me
Yesterday,after I flashed stock ICS rom through odin, I noticed that i can't connect to any kind of wifi connection, even wifi sharing from other devices! it says just "obtaining ip address" and nothing. stuck like that forever. What?

My problem was unable to turn on wifi, wifi stuck at the stage of turning on.... and forever like that cant off and on.
Most probably is hardware problem coz i have tried many ways to solve including flash back to stock rom,change modem,change kernel and etc.
good luck for you,hope you are not the same problem with me.

Wifi is kernel-related.
So, try to flash another kernel to test.
Or if you don't want to flash another kernel, check in menu Settings > wifi > (menu button) Advanced > Use static ip.
Try to enabled and connect.
Then disable and try to connect.
If that does not help, try to wipe cache (and Dalvik cache) in recovery mode.
Press Volume UP + Home + Power buttons as long as the recovery menu appears, then select wipe cache and reboot the phone.
P.S.: Check the configuration of your wifi router / WLAN access point, that is allows your phone to connect.
ok so i did everything again just to be sure and... my mistake! the problem starts not after the rom flashing but after cf root! have i done something wrong maybe?
I would say look for a custom rom that is already pre-rooted so then it should have all bugs to do with wifi removed.
I used to have a problem with the wifi myself which caused problems when turning it into a wireless hot spot and then wouldn't turn back off again.
But now im on the Custom Rom I am having no problems with wifi at all.
Hope this helps.

Actually, I would say try a different kernel. CF-root is a kernel. Wifi drivers are in the kernel. Ergo... ?
Wifi is kernel related issue
try changing your kernel

Im having the same problem here, any luck so far?
may have something to do with the root. my phone had this issues once. just flash your phone with the correct rom and do NOT root it again as it may have something to do with the root itself. or just something got messed up during the rooting process
I am having a problem connecting to a EAP secured wifi network on cMiui (same problem exists on Mystic's Glory 4.1).
What is strange is that connecting to the same network works without any problems on CM9 (nightly build 7/2). I have tired the usual suspects, reflashing the rom, re-booting, turning airplane mode on and off with no success.
I have edited the wpa_supplicant.conf file to add the network (I also copied the version I used with success in CM9) but that doesn't help. The last thing I have tried is manually copying over the bcm4330.sta.bin and wpa_supplicant from the working CM9, then re-booting but still no joy.
Does anyone have any ideas? I am sure it is something simple but I can't seem to find it.
What kind of problem are you having?

Ugh, that would have been good to include in the original post!
The issue is that the wifi never connects, always stalls at the association stage. Looking at the logs, the error message is: Association request to the driver failed.
Any ideas?
Have you tried switching up the kernel? I'm running AOKP with Siyah and it's connecting to my school's EAP network just fine.
Yup I tried both fluxxi and siyah. No good still does the same thing, wireless network appears to not be in range and fails during the association process.

Hm...I'm not really sure what's wrong, but at this point, I would just try a full wipe and reflash the ROM, - shrugs -.
Or try resetting your router?
