Subject: ath5k: monitor mode needs channel change
Date: Thu, 30 Jul 2009 23:31:43 +0200 [thread overview]
Message-ID: <4A72113F.8000604@gmx.de> (raw)
I currently need an extra trigger by changing the channel after
"ifconfig up" to see any output in monitor mode from ath5k, e.g.
ifconfig wlan0 down
iwconfig wlan0 mode monitor channel 1
ifconfig wlan0 up
# no output by tcpdump -n -i wlan0 in another xterm
iwconfig wlan0 channel 2
# tcpdump output starts
The second "iwconfig" call must specify a channel different to the
first one.
The above sequence without the second "iwconfig" works fine with a
RTL8187 device.
I'm running
compat-wireless-2.6: master-2009-07-26-11-g83c091c
wireless-testing: v2.6.31-rc4-29204-g6b3a8c9
on top of a 2.6.30 kernel.
The WLAN NIC is a:
02:00.0 Ethernet controller: Atheros Communications Inc. AR242x
802.11abg Wireless PCI Express Adapter (rev 01),
PCI id: 168c:001c (rev 01)
ath5k identifies it as:
ath5k phy0: Atheros AR2425 chip found (MAC: 0xe2, PHY: 0x70)
It's not a big issue, but a bit annoying sometimes.
