I have noticed a problem when trying to configure WLAN. I can setup anything, but WLAN does not work. After booting and trying several times I noticed that the numbering og the network interfaces was a little bit strange: eth6 and wlan2… I figured out that removing/renaming 70-persistent-net.rules fixed the problem. After that I got eth0 and wlan0 and WLAN worked!
mv /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/70-persistent-net.rules.inactive
I don’t know if this is a problem with my LAN setup or if this is a problem for everyone…
