I have recently boughgt a second hand Latitude D600 

 

I am told it has Centrino Mobile Tech wireless connectivity

Intel 2200 b/g mimi PCI wireless LAN

XP Pro

 

 

I have installed a wireless router at home - but cannot make any connection to laptop.  As I don't have the service tag, Dell won't help!!

 

Can anyone out there help a very frustrated lady?????
