Comment 3 for bug 107630

I have the same problem.

I have a WiFi USB adapter and if I configure the WiFi network in /etc/network/interfaces, avahi-daemon fails on boot.

This is my /etc/network/interfaces file:

auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet dhcp
name zd1201
wireless_channel 3
wireless_mode managed
wireless_essid THOMSON
wireless_key [MY WEP KEY]
address 192.168.0.11
netmask 255.255.255.0
gateway 192.168.0.1

One solution is not configure in /etc/network/interfaces, and when GNOME starts, configure manually the WiFi using Network Manager, but this method is ugly.

I don't know why there isn't a solution.
