My laptop's wireless card runs fine at home. I have a problem connecting to the wireless network in school. They have this thing where after your wireless card makes a connection, you first have to open a browser which then diplays a login form. Once I've entered my username and password, the wireless access runs fine. This all works when I boot into Windows. It used to work the first time I tried it in Linux, but now it won't, and I don't believe I've changed anything since that time.

This is what I get when I run ifup from the command line:

eth1 device: Intel Corp. PRO/Wireless 2200BG (rev 05)
eth1 configuration: wlan-bus-pci-0000:02:09.0
eth1 warning: using NO encryption
Starting DHCP Client Daemon on eth1... . . . . . no IP address yet... backgrounding.

Can someone please help!
