I have been working since Dec 26 to get my wifes Thinpad T40 with Aironet MPI350 mini PCI Wireless card to connect and work with my Linksys wireless router at home. My T60 works fine . The MPI350 has been replaced with a different card and I get the same response. This is true at home, work and the local coffee shop running WEP, LEAP and no security respectively. The common behavior is to be able to "Associate" which I think is a physical connection but any attempts to ping or use the Web are not successful. I get the feeling this is software / config. issue and the T40 Thinkpad laptop is a lease return that I suspect worked fine before the hard disk was reformatted and the latest drivers / utilities installed for XP Service Pack 2, ( SP2) . I am specifically wondering what Driver / Firmware combination will work with XP SP2 for the Aironet MPI350 adapter ?
