Please can someone advise - I have XP Home on desktop with PCI wi-fi card, and WinME on ancient laptop with wi-fi PC card; tried creating ad-hoc network between the two using XP machine and floppy disk, but neither able to see each other. For this exercise I am not using any internet at all - just a plain and simple(?) two machine network. Also tried allocating 192.168.1.1. to XP machine and 192.168.1.2. to laptop - although both machines indicate a connection, there is absolutely no communication between them. Both are in the same room. "File and Printer Sharing" is selected on both. Thanks for any help.
