Wifi card not working after resume from suspend

[Someone]

Wireless card (brand is intel) does not work after i suspend the system (thinkpad x230) gets suspended with Fn-F4.

ifconfig wlan0 down
ifconfig wlan0 up
service netif stop
service netif start
dhclient wlan0

arent fixing the problem. Any idea whats the cause? I suspect its something kernel related. Thanks.
By the way is there another freebsd key combination that suspends the system?
