>Description:
i'm not able to connect to my router using WEP encryption. if i disable encryption in my router i'm able to connect without any problems.

i'm using the following wifi-card:

ath0 at pci0:5:1:0:        class=0x020000 card=0x5a001385 chip=0x0013168c rev=0x01 hdr=0x00
    vendor     = 'Atheros Communications Inc.'
    device     = 'AR5212, AR5213 802.11a/b/g Wireless Adapter'
    class      = network
    subclass   = ethernet



my rc.conf contains the following wlan related entries:

wlans_ath0=wlan0
ifconfig_wlan0="inet 192.168.1.10 ssid XXXXXX wepmode on authmode shared wepkey 1:0xXXXXXXXXXXXXXXXXXXXXXXXXXX wepkey 2:- wepkey 3:- wepkey 4:- deftxkey 1 channel 11"



this is the output from ifconfig:

ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 2290
        ether XX:XX:XX:XX:XX:XX
        media: IEEE 802.11 Wireless Ethernet autoselect mode 11g

        bgscanidle 250 roam:rssi 7 roam:rate 5 protmode CTS wme burst ff

enabling wlan debugging using wlandebug scan+auth+assoc revealed the following errors:

Nov 20 19:24:58 moshnroll kernel: wlan0: notify scan done
Nov 20 19:24:58 moshnroll kernel: wlan0: [XX:XX:XX:XX:XX:XX] recv auth frame with algorithm 1 seq 2

Nov 20 19:25:00 moshnroll kernel: wlan0: [XX:XX:XX:XX:XX:XX] sta_assoc_fail: reason 1 fails 2

please tell me if you need more info from the debug output.
