I have Ubuntu 1.8.10 server with X and gnome installed. I am attempting 
to get my USB wireless adapter working on it.



Here is the output from lsusb:
Bus 001 Device 006: ID 050d:705a Belkin Components F5D7050A Wireless Adapter

The messages log shows the following:

I have tried adding necessary info to /etc/network/interfaces, but no 
go. Wi-fi radar does not work. Ndiswrapper will not work on this 
architecture, and iwlist wlan0 scan does not work.

The adapter works fine on my Linux Mint laptop.

Any idea what steps I need to follow to get this adapter working?
