Advice on Intel Wireless card

[Greg Sieranski <greg.sieranski@xxxxxxxxxxxx>]

I currently have a t60p with an  Atheros Communications, Inc. AR5418 
802.11a/b/g/n Wireless PCI Express Adapter that I have had very minimal 
luck getting to work. The madwifi drivers are just not working 
consistently enough for me to even bother turning on my wireless. I am 
ready to swap the card for either the Intel Wireless WiFi Link 4965AGN 
or the Intel PRO/Wireless 3945ABG card. I was just looking for some 
advice on which card I should go with. I would really like to be able to 
just put the card in, install the firmware drivers and have it work. 
What do you guys think?

Thanks,
gs
