Thanks for your reply Guy. We seem to be connected as long as we dont turn anything off, then the link disappears. All Pc's are in the right workgroup and will transfer files etc, and even print just the once. The its all gone!
I can only think that the radio link is too weak to hold in as my PC's are on the front of the house, while the transmitter and main net are in my sons office at the back.
All Pc's run XP, we have used the connection wizard, and set up manually with the same result.
Thank you for taking time to read this.
Mike
