Has anyone facing WIFI issue? Mine upgrade to ICS 4.0.3 using for 2 weeks and yesterday suddenly the WIFI unable to connect to my home router, purposely go out to cafe that has support wifi aslo can't connect to them.

I also do hard reset to the phone - the wifi also fail to connect.
I also do *#526#* and shut down the phone for 30min - the wifi won't perform it's job
I also do numbers of times of switch off and switch on - the wifi won't perfom it's job to connect!

Any kind soul here to comment and give a help!

Sigh!
