All,
Just an update on getting wifi working on my T430. While I loved learning about the build process and was happy to explore the build your custom image idea, it turns out that 8 bucks on ebay and my problem was solved. I ordered up an Intel Centrino Advanced-N 6205 62205ANHMW to replace the lame Intel Centrino Wireless-N 2200 2200BNHMW that was originally in the T430, removed the 2 keyboard screws, lifted off the keyboard, replaced the old with the new, put everything back and rebooted - solid, now I got 5 Ghz frequencies and it works flawlessly with my debian and sculpt installs. Highly recommended upgrade - its even a bit faster at negotiating with the access point.
Later,
Will
