Comment 11 for bug 105872

I had a problem with Ubuntu 7.04, where I couldn't get an IPv4 address via DHCP over my wireless interface. However, DHCP worked fine over my wired interface, and if I configured my wireless interface to use a static address that worked too. Because roaming mode assumes that it's a DHCP client, that didn't work either. Iwconfig reported sensible values in both the DHCP and static cases. The eth1:avah interface appeared transiently, as reported above.

Per the last poster's suggestion, I removed /etc/network/*/avahi* and that fixed the problem.

This was on a i386 machine, using the alternate CD install. I'm using an Orinoco 802.11B "silver" card.
