Totally Hosed Network - Don't know where to start.
Okay, so at one point, this was working, then I dist-upgraded and a whole mess of settings changed and I don't know enough to know how or why. Boo hoo. Anyhow, let me see if I can explain what I'd like to accomplish.
I want to setup a LAN with the internal domain name of "borg.lan". I'm pretty sure that can be done. I have three machines that do networking: a Windows XP laptop with a wireless 802.11g/b card and an ethernet jack [7of9.borg.lan], a wireless router (LinkSys "Compact Wireless-G Broadband Router" Model#: WRT54GC)[unimatrix.borg.lan], and a DELL P4, 2.8GHz, 512MB RAM running Ubuntu 7.10 (Gutsy Gibbon) with a wireless 802.11g/b card and an ethernet jack [locutus.borg.lan]. The connection to the Internet is through a secure wireless connection to the college. For whatever reason, the laptop gets a poor signal, so I'd prefer to rely on the Ubuntu machine picking up the wireless signal, routing it to the WRT54GC wireless router who would then provide DHCP connections via wireless or four wired ports.
I know that I had been using wifi-radar to get a signal before and that it was working solidly. Now I can't seem to get a signal or correctly configure the wireless card. I remember installing the ndiswrapper for my wireless card.
I ran a script I saw someone else using on here and it gave me a lot of data. I'll share it with you. I know that there are a lot of files that go into the network setup. I just don't know which ones I need to configure. Please help?

./collectNWData.sh
I can only assume that I ran it correctly. I ran it on locutus.borg.lan and this is the output file it generated:
Code:
collectNWData.sh V0.5.0.1
