What wireless device do you have? I think "ath0" would be some Atheros 
chipset but which one? 8.04 had the madwifi driver but now the driver is 
in the kernel, maybe your chipset is not yet supported correctly? To 
find out what chipset you have, use the commands

lspci
sudo lshw -C network

in a terminal and post the relevant part of the output. And if you want 
to find out the wireless interface name you can try the command

ifconfig -a

in a terminal. It will show you the configuration of all interfaces 
known to your system.

If you have problems getting the network manager working it may be 
useful to replace it with wicd. You can install the wicd package from 
the 9.04 repository.
