Thanks.  Here's a short video that shows what happens when I turn on the laptop. I hope it's clear enough to be helpful.

Astrid,

When your GNI login window comes up, does it say Debian, or Ubuntu?
Next to the username and password box, you should see a menu that
selects your desktop. If you pull this down, you should see Gnome,
Unity, XFCE, LXDM, or possibly FVWM. I, and a bunch of other people
here, love FVWM, but I highly do not recommend it for beginners.

When you log into Gnome or Unity, you pull the menu down at the top
right-hand side of your screen, and networking is one of the options.
You need to know what your wireless device is called, and you need the
password.
