Did you go into the Network from System and activate the wireless you
found there?

The movement is probably due to the touch pad. You need to go to the
Touch pad makers site to see if they have a Linux version driver. Or
switch of the touch pad and use a plug in or wireless mouse,

Yes, I did go into the Network from system and activate the wireless.
I have a wireless pcmcia card from another laptop that I have tried.
It does see that card, but it will not connect. I have put in my WEP
till I am sick of it and it still will not connect. If I connect the
wire from my DSL then I can connect to the internet.

I do have a mouse. I will still go look for the Linux version driver.

I think your card requires ndiswrapper to be installed.
It depends on what the chip set is in the WIFI card.

Then its the driver for the card. go to the card manufacturers site and
see if there is a linux one, if not its a different card for you. You
could of course do a google search for linux driver for it, you never know.

In the interim, I got my wireless light to light up, but still cannot
connect through the wireless. My router is a Microsoft Broadband
Networking MN-700. Is that my problem? I have looked for drivers for
it. The ones I found were .exe files and I couldn't do anything with
them in Heron. Do I need drivers for it?

I think I need to try redoing my wireless network and see if that helps.
