[Thinkpad] I have an Atheros 802.11g 108MB card in a T23 and Idon't notice any improvement wifi range over my B or G card

Hello,

Likely the antennas are being blocked or detuned by the LCD.  Laptops tend to have the antennas at the top and side of LCD.  You need to put the antennas in the gap between the LCD and the outer covering (lid).  For best performance antennas have to be away from other metal objects and have the widest clear view possible.  For laptops it is a compromise.  Some plastics and metals used for the lid can attenuate signals.

If the laptop has a wi-fi version you might try to get the lid component that has the antenna built-in.  Otherwise talk to an engineering student studying RF Engineering.

This version of the thinkpad didn't come with wifi but I "modified" it with
a mini pci 108 MB wifi card.  I ran the antennas behind the LCD and the
excess cord I made sure was as high up on the screen as possible.  I notice
when I try to connect to my wifi network at school, the newer laptops seem
not to have a problem connecting to the network but I almost have to sit
next to the router.  I will post the number of the card but it's 108 MB card
sp it should be able to communicate at least as well as the cards in the
newer laptops right?  What are some ways to improve the range?   I know this
was a hack and it might have to do with the amount of power going to the
card not being sufficient for wifi as one theory.  Any ideas would be
appreciated.
