Thanx for the input. This is my e/n/i:
<snip>
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp
iface dsl-provider inet ppp
pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf
provider dsl-provider
</snip>
As may be readily seen, the wireless interface (eth1) is not even
mentioned therein: it's obviously managed dynamically by network-
manager. That's why I'm reluctant to mess with it, lest I break it
beyond repair.
Furthermore, there was this article stating that configuring the e/n/i
file was *not enough* (on Debian at least):
http://krzysztofcierpisz.blogspot.com/2009/04/debian-change-from-dhcp-
to-static-ip.html
And all this from a guy
who, in his own words, goes xp (extreme programming) -- not from a
newbie like me! No wonder I'm afraid to touch anything in my Debian
config files ... At least until I get to know my OS a little better ...
