HTC not connecting to WiFi network
I've got a strange issue with my HTC wildfire (standard HTC 2.2.1 f/w) where it will try to connect to my home network, but fails. It has worked fine up until now, but now it just gets it self stuck in a loop (connecting to network > authenticating to network > obtaining IP from network > disconnected). All other devices work fine (ipods, laptops and games consoles).
I have tried two different brands of router/WAPs (netgear dg834gv5 and some ancient belkin) with varying levels of security from unsecured networks to WPA and WPA/WPA2 secured networks. Wifi channels have been changed without success.
I've even reset the spare DG834Gv5 i have to it's default settings without any luck.
Is there anything else I can try before sending it for repair?
Thanks for reading :)
