Re: [Madwifi-users] IBM Thinkpad 600X + Netgear WG511T cardbus(Atheros AR5212 chipset) + VectorLinux (kernel 2.6.18.5) withpre-built MadWifi support: empty results on "iwlist ath0 scan"

[John <joh...@ho...>]

dmesg has the following wifi0: entries:-
11b rates: <and a bunch of rates from 1 to 11Mbps>
11g rates <1 to 54 Mbps>
turbog rates: <6 to 54Mbps>
h/w encryption support: WEP AES AES_CCM TKIP

use hw queue 1 for WME_AC_BE traffic
use hw queue 0 for WME_AC_BK traffic
use hw queue 2 for WME_AC_VI traffic
use hw queue 3 for WME_AC_VO traffic
use hw queue 8 CAB traffic
use hw queue 9 for beacons
Artheros 5212: mem=0x12000000, irq=11

ifconfig -a

iwconfig

<Rx and Tx figures - all values==0>

Also, the SSID name on the AP/wireless router appears to other machines so I 
read this as answering "no" to your question as to whether the AP is hidden.
