Wifi suddenly stopped working on iphone

[hetul]

Hello,

I have an unlock iphone.

Firmware: 1.0.2 (1C28)
Modem Firmware: 04.01.13_G

I have a D-Link router with no security. My wifi worked fine for a few weeks before it died... now, it would just not detect the available network. I have tried to use it with different routers at different locations but it would just to detect them!

I had it working nicely without any issues for some weeks. Not sure what caused the issue.

What should i do to get it working?

1. Should i try and Restore the phone with 1.1.1 firmware?
2. If i do that, and the wifi still doesnt work, is there a way to unlock the iphone using USB cable?
3. Is there any other way to troubleshoot this issue?

Any assistance in this matter would be highly appreciated.

TIA

thanks for the reply.

yes, have tried this already... no luck. Is there a way or a script that could run the phone in Debug mode and show me the error messages?

does it mean that it has something to do with a corrupt file? or baseband?
