I recently set up a small wireless LAN between three PC's (a base station PC with a Mecer Wireless Router under W2000, a P4 under XP with Mecer wireless LAN card and my Compaq notebook). This network is up and running nicely. My problem - I tried to link my Intel dual-core 3 GHz under XP x64 by using a Mecer 54 Mbps 802.11g wireless LAN card to the existing wireless network without success. It seems that the driver supplied by Mecer / Mustek is not XP x64 compatable. Any suggestions how I could get the Dual-core PC on the network ?
