You can run Linux in a VM and PCI passthrough your WiFi Adapter. Linux drivers will be able to connect to your wifi card and you can then supply internet to FreeBSD.

Doing this manually is complicated but the whole process has been automated on FreeBSD by "Wifibox"

I tried it myself and it worked pretty well for a wifi card not supported by FreeBSD.

So, no need to get a new laptop :-)
