Hi list,

After updating my pc today, I'm getting following message on the console.
As it seems to be working ok, but is there any way to get rid of it?

My setup are as follows:

rc.conf:
wlans_iwi0="wlan0"
ifconfig_wlan0="DHCP ssid xxxxxxx wepmode on wepkey 1:yyyyyy weptxkey 1 deftxkey 1 country JP"

ifconfig:
iwi0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 2290
        ether 00:0e:35:c2:a2:7b
