Herewith. The /etc/network/interfaces file has been generated by Kubuntu, and
I currently have the Ralink configured to static. When it is configured to
DHCP it vanishes from /etc/network/interfaces.
The 3 things together are rather long, I'm afraid. I'd better say thank you
here at the beginning! So, thank you :-).
