It looks like the AFW-N411 uses the Realtek RTL8180 chipset.
That needs the rtl8180
module loaded to work.
Unfortunately, it's not present on my kubuntu 8.04 distro (strange).
Maybe try a knoppix
"live cd" and boot from that. knoppix
is renowned for good hardware detection, but I don't know how well it'll cope with only 128MB RAM.
Try putting rtl8180
and see what you can find.
