Help HELP: HTC Wildfire WI-FI Problems

[b1gj4v]

Hi

My sister in law has a HTC Wildfire mobile phone, she use to connect to my router, i even connected it for her, and out of the blue the connection dropped. It was working fine though before hand.

I have a belkin wireless n1 router. security wpa/wpa-2 (something like that ) its even gone back for repair, they have put in new wireless part in the phone, it picks the wifi up, connect to it, insert password and then when obtaining ip address after that it just doesn't want to know. Just disconnects and then goes back to Connecting and carries on.

Android Version: 2.2.1

Once the phone was updated from previous Android Version the WI-FI stopped working, been in for repair twice, they said its working fine and sent it back. What can i do now? Downgrade? Lost for idea's now

Thanks

UPDATE: it is working on 2 other routers, it tries obtaining IP address from my router then disconnects, why is this? ive done all security types, even without it and still does not connect.

Try to "forget" the router: long-press it in Wifi Settings and select "Forget". Then reboot phone and try again.

I did that but it says that it is unable to scan for networks!!!
