I've successfully managed to connect my XP laptop to an airport extreme network at a local college, but although the laptop is assigned an IP address it doesn't get a default gateway address - it's just blank. Unfortunately this means I can't connect to the internet as the proxy server is on a different sub-net. I can ping all the macs on the same network but can't ping the proxy server. The macs connect to the internet through the proxy fine. I've tried forcing the laptop to a fixed IP address and manually entering the default gateway to no avail.
Any ideas gratefully received.
TIA, Mark.
