Not like it's hard. But seriously.

Just gotta remember that the setup form is at http://192.168.1.1/ and it's intuitive from there.
However, getting my dad's slow XP home laptop to connect to the damn network was a problem. For some unknown fucking reason, the "Network Connections" dialogue (and all related dialogues that I could find) would only accept a WEP key, not the network password... which my personal laptop accepted just fine. I am obviously missing something important here. Anyway, everyone's all connected to the internet and stuff, so I'm going to go work on my own stuff now.
