It does look as if the laptop adaptor is having problems. What is odd is 
that this also affects a PCMCIA card as well as the built-in one. Try using 
the laptop near a different router (if you have access to one) to see 
whether this makes any difference. Have a look in Control Panel | Network 
and see if the entries for the internal and PCMCIA cards are enabled. Also 
look in Control Panel | System | Devices | Device Manager to see if there is 
any problem with these cards - it would show up as a cross or a eclamantion 
mark by the entry for the card.
