As others have said, there's a physical hardware kill switch, which physically powers off the phy on the wireless card. The hardware rf kill switch is on the front left of the T60. Its got a bit of bright green inset in it, iirc. > My old R51 didn't do this but my new HP has a setting in the BIOS which > will disable the WIFI if eth0 is up.

The T60 definitely doesn't have such a (IMO stupid) feature. :) Just for the record... If you happen to be a Red Hat employee who has a company-purchased laptop... ~2 years ago, safe bet it was a T60. A year ago, it was a T61 (I have a T61, though I bought it myself). Nowadays its the T500 (new versioning scheme, but it looks just like the T60 and T61). So anyhow, its a pretty safe bet those models have been pretty well tested running Linux and work quite well -- including iwl3945 on a T60. :) --jarod
