Hi
Is there a magic order in which media options should be passed to an atheros
interface. Changing the sequence seems to make a difference e.g. :
1) ------------------------------------
ath2# ifconfig ath0 ssid ath101 10.10.20.2/24 mediaopt adhoc channel 36 mode
11a media OFDM/6Mbps
ath2# ifconfig ath0
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.10.20.2 netmask 0xffffff00 broadcast 10.10.20.255
inet6 fe80::205:5dff:fe95:ef2e%ath0 prefixlen 64 scopeid 0x4
ether 00:05:5d:95:ef:2e
media: IEEE 802.11 Wireless Ethernet OFDM/6Mbps (OFDM/6Mbps)
status: no carrier
ssid ath101 1:ath101
channel 36 authmode OPEN powersavemode OFF powersavesleep 100
rtsthreshold 2312 protmode CTS
wepmode OFF weptxkey 1
---------------------------------------
AND
---------------------------------------
ath2# ifconfig ath0 ssid ath101 10.10.20.2/24 channel 36 mode 11a media
OFDM/6Mbps mediaopt adhoc
ath2# ifconfig ath0
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.10.20.2 netmask 0xffffff00 broadcast 10.10.20.255
inet6 fe80::205:5dff:fe95:ef2e%ath0 prefixlen 64 scopeid 0x4
ether 00:05:5d:95:ef:2e
media: IEEE 802.11 Wireless Ethernet OFDM/6Mbps <adhoc> (autoselect
<adhoc>)
status: associated
ssid ath101 1:ath101
channel 36 authmode OPEN powersavemode OFF powersavesleep 100
rtsthreshold 2312 protmode CTS
wepmode OFF weptxkey 1
2) --------------------------------------
If I change the media to OFDM/36Mbps it also seems to forget that if was in
adhoc mode.
ath2# ifconfig ath0 media OFDM/36Mbps
ath2# ifconfig ath0
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.10.20.2 netmask 0xffffff00 broadcast 10.10.20.255
inet6 fe80::205:5dff:fe95:ef2e%ath0 prefixlen 64 scopeid 0x4
ether 00:05:5d:95:ef:2e
media: IEEE 802.11 Wireless Ethernet OFDM/36Mbps (OFDM/6Mbps)
status: no carrier
ssid ath101 1:ath101
channel 36 authmode OPEN powersavemode OFF powersavesleep 100
rtsthreshold 2312 protmode CTS
wepmode OFF weptxkey 1
ath2# ifconfig ath0 mediaopt adhoc
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.10.20.2 netmask 0xffffff00 broadcast 10.10.20.255
inet6 fe80::205:5dff:fe95:ef2e%ath0 prefixlen 64 scopeid 0x4
ether 00:05:5d:95:ef:2e
media: IEEE 802.11 Wireless Ethernet OFDM/36Mbps <adhoc> (autoselect
<adhoc>)
status: associated
ssid ath101 1:ath101
channel 36 authmode OPEN powersavemode OFF powersavesleep 100
rtsthreshold 2312 protmode CTS
wepmode OFF weptxkey 1
