that depends, is it Bluetooth such as the IBM T30 Thinkpad, or is it 802.11b?
that will make a difference on which type of access-point you purchase and install.
personally I stick with Netgear, they have been around for, well, heck they used to be Bay-Networks so I guess it was back in the 70's when they started out.
Downsized and opened up the Netgear line, low price, top quality and solid support...
