That culd be your problem. I think it's looking for an IPV6 network
and not finding one. Unless you know your network is using IPV6,
chances are it is using IPV4.

You might look at the results of ifconfig and iwconfig. My ipw2200
shows as follows:

[root at dragon fc6]# ifconfig eth1
eth1      Link encap:Ethernet  HWaddr 00:13:CE:07:35:8C

NetworkManager is very verbose; you might try it and see what shows up
in /var/log/messages.
