Wireless USB adapter

[apffal]

I have a Linksys wireless USB network adapter, model WUSB11, version 2.6, and want to use it with Mandrake 10.0 or, alternatively, with Suse 9.1.
I think it is recognized when inserted, because I can see this output in a Mandrake console :

However, I cannot use it for Internet connection.
What steps must I follow ?
Thanks in advance.
