Wifi not working (Galaxy S2)  

post #1 of 24
Thread Starter 
Since a few days ago the Wifi on my Galaxy S2 refuses to activate



It has happened several times before but rebooting fixed it, it doesn't seem to work anymore though, I tried rebooting, shutting down and restarting... nothing.

The only thing I haven't tried is doing a factory reset.

I'm running stock 4.0.3.

If it takes a hard reset maybe I should try installing CM9, but I have no Idea how to do it, there's many ways to do it, many kernels, root, etc. I've tried reading about it but everyone says something different so I don't know how to proceed.

It's not, I tried disabling it and still no-go, the thing is, the Wi-fi icon remains that way and I can't enable or disable it, pressing it does nothing, same if I try it via the settings menu of the phone

Did you try connecting to a different wifi network or resetting your own? You can also try going into Setting>wi-fi then long press your own network and select "forget network". Then set it back up.

The problem happens before that, I can´t connect to anything because i can´t turn wifi on



Pressing Scan or Add Network does absolutely nothing, the toggle doesn't work either, it just stays like that

Might be time to try it.

I second this. Back up contacts/pics/vids. If that fails, it's off to your carrier store for warranty replacement

I bet you have lookout mobile program installed?

UNINSTALL the program.....


Youll see it here:

Settings>applications>running.....


Stop them all that have lookout, then WIFI will work like NEW

Any success with this problem? I am having the same problem from today.. Running 4.0.4 . I don't want to do a factory reset without confirming that it is going to help me resolve the problem.
