First attempt (unsucessful):
After "apt-get remove network-manager" and reboot I lost "eth0" and "wlan0" in the output of "ifconfig -a". I re-installed network-manger and kill wpa_suplicant for wlan0 but it did not help (still no IP).
Second attempt (seems to work):
"apt-get install wicd" and /etc/network/interface with "auto eth0 \n iface eth0 inet dhcp".
I can connect wifi via wicd-gtk now.
(To install wicd I had to wget the deb-files on a second machine and to copy them to /var/caches/apt/archives)
