I recently bought the WRT54GS, WPC54GS and WUSB54GS. After i set up WRT54GS, and install the WPC54GS on my laptop, which running W2K server, everything works fine, excep that the WPA protocol can't be used, in the end, i used WEP and it works. But, the biggest problem here is, when i installed the WUSB54GS on another PC running W2K professional with SP4, it can connect to the router, but could not get IP from the router. I tired to configure static ip, but could not get the connection to other LAN hosts and Internet. For the router, the fireware version is 3.37.6, and for the WUSB54GS, the firmware version is 220.127.116.11 and driver version is 5.1.3538. May i know anybody else encounter the same problem before? Or it is due to the card hardware issue? Thanks a lot for your help!
