I have some questions on my home wireless connections.

Background, I have a Modem, wireless router combination from my ISP.  (ATT)  I have my Dell Dimension 2400 desktop as my "base" station.  My husband and I both have Dell laptops.  I just swithched ISP's and I loaded ATT's software cd" onto the base station only.

When either or both us turn on our laptops in another room we connect to the internet with no problems.  

A friend came to visit, she did the same as my hubby and I do, turned on her new Dell laptop in another room and her ocmputer would NOT connect to the internet at all.

I have two questions, how secure is our wireless service and why could our laptops connect and my friend's not connect.  None of the 3 laptops were physically
 configured in any way to ATT's service.  The ONLY ATT internet software loaded onto any of the 4 computers was the Dell Dimension 2400 base station.  

I hope that I have made this clear.  Oh and our 3 computers are running XP and my friend's is running Vista, although I didn't think that would make a difference.

Thank you for any help.
