[TAG] Mandriva 2007 - WiFi cards cannot find network

[OS]

I have wondered about eth0, however I kept returning to the fact that WiFi 
works on a different partition running Mand 2006 on the same machine. The 
proof - I'm using Wireless now on Mand 2006. 

On Mand 2006 route -n produces 
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     0.0.0.0         255.255.255.0   U     0      0        0 ath0
0.0.0.0         192.168.0.1     0.0.0.0         UG    0      0        0 ath0

Wow ! very different !

On Mand 2007 after a fresh reboot route -n produces 
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     0.0.0.0         255.255.255.0   U     35     0        0 ath0
169.254.0.0     0.0.0.0         255.255.0.0     U     35     0        0 ath0
0.0.0.0         192.168.0.1     0.0.0.0         UG    35     0        0 ath0

There's no eth0 but where on earth did 169.254.0.0 come from. I've tried 
reconfiguring the interface but I cannot get rid of 169.254.0.0 nor can I 
find it in any configuration.

Thanks,
Owen
