Very valuable responses; this is one of the emails I will keep for
future reference.

BTW eth0 is my wired ethernet card and eth1 is my wireless card. Why
eth1 is not wlan0?

One other issue is no mater what I do in /etc/network/interfaces when
I go to K-Menu>>System Settings >> Network Settings I see different
parameters
and IP addresses. If I disable eth0 from there and restart the
computer, the eth0 is enabled again.

Below is my interface config file content. Would you please check and
tell me if it is ok.
