I need to buy a wireless adaptor for my PC that is compatible with a SMC wireless router (802.11g) that is being provided by my ISP. My PC has a Gigabyte nForce3 GA-K8NS Pro m/board with an Athlon 64 bit processor. I use Windows XP Pro as OS. Can't seem to find out much about the SMC routers. Can anyone recommend an adaptor that is compatible? Also should I consider a different router? There will be two Laptops and one PC sharing the system.
