I've had my phone since the beginning of February but I have not tried using the WiFi until now. The only way that I can get a decent signal is if I am right next to my wireless router, and as soon as I walk a few meters away I lose connection. I downloaded the 'WiFi Analyzer' app and the only WiFi signal I could pick up was mine while my laptop picks up WiFi from people who live down the street. It has the same problem with every other router I try. 
Any suggestions would be great!
