I've wondered for a long time why Cisco chose to use keyidx>0 for WEP unicast keys, but I think I finally understand that this is a weird feature (8.5.1): In a mixed WEP and TKIP network a WEP key[0] would conflict with the TKIP key (which must have keyidx == 0), forcing a dumb TKIP STA to downgrade to WEP. (A good TKIP STA would just rely on per-STA keys and not have this problem) Volker Braun - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
