[Bug 264238] WiFi stops working after upgrade from 13.0 to 13.1, AR9285

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=264238

/etc/wpa_supplicant.conf has lines for the WiFi as:

network={                                                                       
 ssid="WHU-STU"                                                                 
 key_mgmt=NONE                                                                  
}

which works in 13.0.

ifconfig wlan0 reports:

wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether 1c:4b:d6:ca:3e:ac

Though it says it's connected to my network (WHU-STU), but there is no internet
access, nor can I open athentification page which automatically prompts in 13.0
when I open firefox. My orgnization has a adimistrator page for us where we can
find out our connected devices, and I cannot find my laptop there either though
ifconfig says I am connected. But I suppose this is normal since I am not yet
logged in now.
I tried service netif/dhclient restart, none worked.

I boot into 13.0 boot environment and WiFi works again. ifconfig reports:

wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether 1c:4b:d6:ca:3e:ac
