Issue with WEP and ath wlan driver on 6.0-STABLE

[Lukas Razik]

Hello!

Yesterday I've cvsuped my 5.3 system to RELENG_6 and now I have an issue with my Atheros 5212 wlan card.
The problem is that if I don't use WEP mode then all works fine. But if I want to use WEP as I've done it under 5.3-RELEASE then I can't ping any hosts in the network (I wait and get no answeres and no error message from ping)...
I've tried to load the wlan, wlan_wep, if_ath modules in different ways (from loader.conf, manually, in different order...) but there's always the same problem - i can't get a connection to the wlan network.

The loaded kernel modules are:
...
wlan.ko
wlan_wep.ko
if_ath.ko
ath_rate.ko
ath_hal.ko

The config line in rc.conf is:
ifconfig_ath0="inet 192.168.0.12 netmask 255.255.255.0 ssid razik.de wepmode mixed wepkey 1234567890123"

The ifconfig ath0 output is:
ath0:...
  inet6 ...
  inet 192.168.0.12 netmask 255.255.255.0....
  ether ...
  media: IEEE 802.11 Wireless Ethernet autoselect (OFDM/54Mbps)

  authmode OPEN privacy MIXED deftxkey UNDEF wepkey 1:104-bit txpowmax 47
  protmode CTS burst bintval 100

dmesg output is:
ath0: <Atheros 5212> mem .....
ath0: Ethernet address: 00:0f:a3.......

Does anyone have an idea what there could be wrong?
