Setting parameters with iwconfig does not bring it down but ifconfig'ing it up does... Card is known as 02:02.0 Ethernet controller: Atheros Communications, Inc. AR2413 802.11bg NIC (rev 01), it is an Askey AR2413A (802.11b/g) FCC ID:PPD-AR5BMB5 IC:4104A-AR5BMB5 Madwifi (with evil closed HAL code) works on the same card (with somewhat weak reception which is annoying as I got an Atheros-based card to get a better radio than the Broadcom-based ones I have lying around...) More info available on request...
