Updated to kubuntu 8.10 and iwlist wlan0 scan sees all the neighbours' WLANs but not mine. Surreal. Note that this WLAN is visible and works from a Mac, from my mobile phone, and also for my laptop until yesterday.
Removed WPA2 encryption from WLAN, didn't help.
Booting 8.10 with my previous kernel, 2.6.24-21-generic "solves" the problem but this is not the preferred solution of course.
So, here's the complete info...

huh? eth0 unknown? What am I using now then? Whatever...
Hope somebody has an idea!
