[gentoo-user] Atheros chip with airodump-ng

[Mick]

Hi All,

I have been experimenting with my wireless cardbus and cannot get it
to work with airodump-ng:

From lshw:

     *-network
          description: Wireless interface
          product: AR5212 802.11abg NIC
          vendor: Atheros Communications, Inc.
          physical id: 3
          bus info: pci@0000:04:00.0
          logical name: wifi0
          version: 01
          serial: XX:XX:XX:XX:XX:XX
          width: 32 bits
          clock: 33MHz
          capabilities: pm bus_master cap_list logical ethernet

latency=168 maxlatency=28 mingnt=10 module=ath_pci multicast=yes
wireless=IEEE 802.11g

lspci -v gives:

04:00.0 Ethernet controller: Atheros Communications, Inc. AR5212
802.11abg NIC (rev 01)
        Subsystem: PROXIM Inc Device 0a10
        Flags: bus master, medium devsel, latency 168, IRQ 11
        Memory at 44000000 (32-bit, non-prefetchable) [size=64K]
        Capabilities: [44] Power Management version 2
        Kernel driver in use: ath_pci
        Kernel modules: ath_pci

I am using net-wireless/madwifi-ng-0.9.4

When I run airmon-ng it shows my ath0 interface:

# airmon-ng


Interface       Chipset         Driver

wifi0           Atheros         madwifi-ng
ath0            Atheros         madwifi-ng VAP (parent: wifi0)

Running 'airmon-ng start wifi0' it creates a new VAP ath1 and puts it
in Monitor mode.  So far so good, but running airodump-ng shows no
data being captured.  Trying to stop ath0 (in case it interferes)
shuts down /etc/init.d/net.ath0, although I still get ath1 shown in
iwconfig.

Have I missed something basic here?  Do I need perhaps to add net.ath1
-> /etc/init.d/net.lo in the same way that I have done for ath0?
