Wireless Home Networking

Okay a customer has purchased a Diamond Wireless Home Networking and it will not work to save your life.
Machine 1: Installed the card as it is the first on the network and all went fine and dandy.

Machine 2: A Sony Vaeio Model PCV 120, Pentium MMX 200 MHZ, 64 MB Ram, Sound and Video Built in to the board. We removed the modem as the other machine has a 56K and this one had 33.6..anyway I keep getting "invalid registry entry." All Diamond says is their are not enough resources..someone tell me how this can be as we freed resources via the modem??? If you can help great ..thanx
