Google tells me it has a Broadcom WLAN adapter.

I use ndiswrapper on one PC.  It is very unreliable and should be a
last-ditch choice.  I've seen people with Broadcom wireless in their
laptops have better success with either the b43 or the STA driver.
There should be documentation for setting them up on the Ubuntu website.

It's perhaps more commonly know as the network name.  All available
networks are displayed in a list if you click on the WiFi icon in the
top-right corner of the desktop, usually you just click on yours without
having to enter anything.

This is really not necessary; you should be able to select your WiFi
network from a list, and it will be set up automatically.

Purely informative, you can use anything here.

This is the name of the network, as configured in your Wireless
router/access point.

Infrastructure is correct.

The MAC address of the access point; you can leave it blank.

I'm confused by this one.

Strange.

If you click on the WiFi icon, do you see the name of your network in
the list?  When you click on that name, what happens?
