>Description:
Problem first started on 9.0-RELEASE, i upgraded first to 9-STABLE, then to 10.0-CURRENT but the problem remains.

On a daily basis, my wireless NIC AR9285 looses connection. I use it on two APs, home and work, both of which are configured with WPA2-PSK. Issuing /etc/rc.d/netif restart sometimes restarts computer. Issuing ifconfig wlan0 destroy sometimes hangs computer. I suspect this could be related to vboxnet.ko kernel module, as problems seem to be more frequent when having virtual machine with bridged ethernet on.
>How-To-Repeat:
Wait for the lost connection.
Issue /etc/rc.d/netif restart or
Issue ifconfig wlan0 destroy
>Fix:
