Sounds like an IP conflict, If each one works on its own then they may be
conflicting when both are on.

Make sure your router is set with DHCP on and both computers are set to
aquire IP automaticly in the TCP/IP network settings.

You may have to reset your router as well.
My system sometimes wont let a computer back on unless I release all leases
and reaquire them.
