I was at a hotel. I had a dhcp lease for 10 minutes, then my network connectivity died.
I rebooted several times. I ran network monitor on the network and could see other
machines etc. I hand configured my network, by copying the setup from the business
center pc, (I randomly picked an ip address in the valid range) and sniffed. Although
I could see broadcast packets I couldn't ping the default gateway.
Why do you suspect that I couldn't ping (or use) the default gateway? I could ping
it from the business center.
