The problem was that my ath0 was acting as an access point instead of a
client. Note the DS (Distribution System) in the original ifconfig output:
% ifconfig ath0
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.1.55 netmask 0xffffff00 broadcast 192.168.1.255
inet 192.168.1.54 netmask 0xffffffff broadcast 192.168.1.54
ether 00:11:95:92:72:55
media: IEEE 802.11 Wireless Ethernet autoselect mode 11g (DS/11Mbps)
status: associated
ssid yagi channel 2 bssid 00:14:bf:27:f1:bc
authmode WPA privacy ON deftxkey UNDEF TKIP 2:128-bit TKIP 3:128-bit
txpowmax 36 bmiss 7 protmode OFF burst roaming MANUAL bintval 100
I did 'ifconfig ath0 scan' and rebooted, and now it's a client in OFDM mode
like it should be:
% ifconfig ath0
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.1.55 netmask 0xffffff00 broadcast 192.168.1.255
inet 192.168.1.54 netmask 0xffffffff broadcast 192.168.1.54
ether 00:11:95:92:72:55
media: IEEE 802.11 Wireless Ethernet autoselect mode 11g
(OFDM/54Mbps)
status: associated
ssid yagi channel 2 bssid 00:14:bf:27:f1:bc
authmode WPA privacy ON deftxkey UNDEF TKIP 3:128-bit txpowmax 36
bmiss 7 protmode OFF burst roaming MANUAL bintval 100
% grep ath /etc/rc.conf
ifconfig_ath0="inet 192.168.1.55 netmask 255.255.255.0 protmode off mode
11g"
P.S. Any idea why 'athstats 1' goes kaboom after two iterations?
