I have a 3 year old pc with no ethernet port. I purchased a Belkin Wireless G Router and appear only to be able to connect this to my pc through an ethernet cable which I do not have. I bought a pci networking card but my computer does not seem to be detecting it despite the fact i have windows xp. Also, the card appears to be slightly too short for the port. I bought the router in order to connect my laptop to my telewest broadband connection. Please help!!! Thanks.
