But what I saw with the D-Link card is that by just changing the voltage supplied to the card-- ie, by using the "ignore_cis_vcc" option-- and not changing any other drivers or firmware, the card would go from 104-bit to 128-bit encryption according to the 'dmesg' signon text. It also went from not working to working at the same time. Go figure. cje -- Chris Elmquist mailto:chrise at pobox.com http://www.pobox.com/~chrise
