Ok...

I believe this is where I come in.

Ok...

Yes you do need a password.

Now let me explain more in my case. I use a Wireless Card a Pc3220 (Over Paid for the POS)
but I connect through. A company which happens to be Verizon. (Expensive Bastards)

Now with my service you can not connect to there Network without a password. Now I believe from a little playing around that I did. (Don't ask how.)

That there are 2 passwords one on your own system that you have to do and another one at there Tower that verifies that you are qualified to use there Tower.

Now on the Firewall side that is actually on your side they provide Jack... I don't know just what type of connection you have but I am not sure just where your getting your single and everything from. Though I would recommend that you use a Firewall. Duh...

If you need to know anything else about this or Wireless let me know this is where I am (TRYING) to play around in.
