Hi,

ich habe ein Wlan Problem seit einem update. Ich gebe erstmal
folgende Daten aus:

~$ lsmod | grep ip
ipw2100                66395  0

Wenn ich das richtig verstehe, wird die Wlan-Karte erkannt und auch geladen.
Sie findet aber nicht den Access-Point. Jetzt habe ich noch eine ziemlich
chaotische interfaces:

~$ cat /etc/network/interfaces

Beim Bootvorgang automatisch starten
#iface eth0 inet static
#    address 192.168.1.12
#    netmask 255.255.255.0
#    gateway 192.168.1.1

## LAN interface (dynamisch)
auto eth0
# Beim Bootvorgang automatisch starten
iface eth0 inet dhcp

## LAN interface 2
# auto eth1
# iface eth1 inet dhcp

## LAN interface 3
#auto eth2
#iface eth2 inet dhcp

## LAN interface 4
#auto ath0
#iface ath0 inet dhcp

## WLAN interface (dynamisch)
auto wlan0
# Beim Bootvorgang automatisch starten
iface wlan0 inet dhcp

## WLAN interface (statisch)
#auto wlan0
# Beim Bootvorgang automatisch starten
#iface wlan0 inet static
#  address 192.168.1.11
#  netmask 255.255.255.0
#  gateway 192.168.1.1
#
#   wireless yes
#   wireless_mode managed
#   wireless_key 3450738743abefcd7932103356
#   wireless_essid bolsena

Wo könnte der Fehler liegen. eth0 (LAN) funktioniert einwandfrei.

Gruss Markus
