I have finally got a signal between my 2 computers,both XP, which is rated excellent. I have used Belkin cards in both using a computer to computer, AdHoc method.I have set the host computer to allow any network to share internet connection, (broadband.) There are 2 problems. 1) there is an error message that there is an IP address conflict, it is set to 0.0.0.0 on the host. 2) I don't know what to do to the 'none host' (guest?) computer to get it to use the internet connection. I would be grateful for any suggestions.
