I've tried wlan_kabel, which likes to segfault and stuff, after I realised google would tell me what to google. It took so long to set up wrong that I forgot I'd asked here, and it's time to sleep now anyway, so I can just wait until morning, as the office will be open, and I can get my proper wired networking then.
