Such a positive response! I am sure that we could find similar
comments for just about any product, laptop or not. And it is not a
netbook...

You might want to try upgrading to Karmic (with the WARNING that it is
still in beta) because it has a newer version of wireless-tools 29.2
that includes /sbin/rfkill, which MAY help ("rfkill unblock...").

http://manpages.ubuntu.com/manpages/karmic/en/man1/rfkill.1.html

If you grep for rfkill in your kernel config, you will see that it
they are enabled, which, I assume, will allow you to use /sbin/rfkill
(I assume). (Same in Karmic.)

If you choose to upgrade:
aptitude update
aptitude dist-upgrade
do-release-upgrade -d -m desktop
