Wifi not finding any network

[silvermongoose]

I have tried everything possible to solve this problem. After 3 handsets various restores and restarts the handset has stopped finding my wifi router (or any others for that matter!). I had it working for 3 days woohoo!!!
Any help hints or tips welcome.

I am getting the same problem after updating to 3.0 . What firmware are you running? I might be restoring my phone to 2.2.1 .
