Problem with atheros at 11b and FreeBSD 6.1-BETA2

[Paulo Fragoso]

Hi,

We have a problem with atheros (D-Link AG530) using FreeBSD 6.1-BETA2 in 
client mode to associte our production bridge (mode 11b), this card 
change to associated state after a long time (9min):

ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 172.16.23.2 netmask 0xffffff00 broadcast 172.16.23.255
        ether 00:13:46:9a:29:13
        media: IEEE 802.11 Wireless Ethernet autoselect mode 11b (DS/11Mbps)
        status: associated
        ssid "WAVE BMARX" channel 3 bssid 00:02:2d:8d:b3:5c
        authmode OPEN privacy ON deftxkey 1 wepkey 1:40-bit txpowmax 18
        protmode CTS burst bintval 100

it was configurated using this script:

ifconfig ath0 inet 172.16.23.2 netmask 255.255.255.0  ssid 'WAVE BMARX' \
wepmode on wepkey 0x3132333435 weptxkey 1 media autoselect mode 11b

Using same hardware and script but running FreeBSD 5.4, this card is 
associated immediately.

What is happening when using FreeBSD 6.1-BETA2? Is there any problem 
with mode 11b and atheros driver?

Our bridge is another PC running StarOS (www.stratos.com) with orinoco 
pccard (802.11b). This is working fine when using clients running 
FreeBSD 5.4, but we can't upgrade this stations clients to 6.1-BETA2.

 From FreeBSD 6.1-BETA2:
# sysctl dev.ath

 From FreeBSD 5.4 we have this:
# sysctl dev.ath

dev.ath.0.%driver: ath
dev.ath.0.%location: slot=8 function=0
