Wifi USB adapter Linksys AC1200 WUSB6300 V2

[Linwood]

I screwed up.  Due to a move going to be without internet for a week or so, and on a whim stopped and picked up a Wifi USB adapter thinking I could just plug it in and connect to my phone's hotspot.

I got the above mentioned device, plugged it in and... doesn't work.

On searching it looks like FreeBSD will add support in 14, not in the current version.

But I also see this page:

https://man.freebsd.org/cgi/man.cgi?query=rtwn_usb&apropos=0&sektion=4&manpath=FreeBSD+12.0-RELEASE&arch=default&format=html

That seems to indicate since 12 it could be added.  I'm hesitant to screw around with kernel changes in my (working, happy, stable) OPNsense system, especially since it is the only place I use FreeBSD.

Did I just simply screw up and should throw this ouit, or is it safe to add drivers as that link indicates?
