The problem seems to be in the tcp/ip settings. In the host it has IP address 192.168.0.1 sub net 255.255.255.0 with no default gateway. my laptop has ip 192.168.0.2 same sub net and default gateway of 192.168.0.1. If I run the network wizard again the connection then works but the ip address is set to automatic. The broadband works but then my zonealarm firewall stops the network working as each pc can not see the other.
