can connect with ethernet but not wireless, conflict with wifi card?

I am connecting to tiscali using a belkin F5D7630 wireless modem router, and a new acer aspire 3694 with vista basic os. i've manged to successfully configure router and can get online using the ethernet cable connection. When i try to connect via wireless it fails and tells me a choice of problems none of which seem appropriate eg "there is possibly a prob with your router or connection". I've tried changing the channel, enabling and disabling security and renaming the network. Also disabled all the firewalls i can find . Belkin tech support suggested may be some conflict with the internal settings on my wifi card from Acer.

Any suggestions?
