Network bridge stopped working
Hi. I'm quite new to Linux, so I apologise for my unfamiliarity with the terminology. I just put Debian Etch on my old desktop computer, and I had it connected to the internet via my laptop's wireless, a crossover cable and a network bridge. When I first installed Etch, the network bridge worked fine, but there was a problem with the display drivers. I resolved that problem, but when I rebooted, Etch just wouldn't connect. It says it's connected, and the DHCP gives it an IP and everything, it just doesn't get the internet.
The laptop I'm using is a Fujitsu Siemens running Vista-32, and it also says that the network is working fine.
Any help I can get would be very much appreciated.
