Hi List.

I have a machine here which has seen three wireless adapters and now 
that I have found one which works in the internal wifi slot for various 
reasons I want to force it to be named "ath0" not "ath2" when the 
machine comes up.

/etc/iftab seems to be what I need to do this but it isn't having any 
effect - anyone know an easier way to accomplish this on Gutsy?  Is 
iftab being ignored because I am using NetworkManager?  How can I 
"purge" the settings Ubuntu has stored on ath0 and ath1?

Here's my /etc/iftab:

ath0 MAC 00:0B:6B:4C:D2:B1
eth0 MAC 00:09:6B:30:FA:EC

I was looking at this page for help with iftab:
