Intel WiFi adapters with model numbers 6xxx and 7xxx require some additions/modifications to wireless stack on FreeBSD. These adapters will not work under FreeBSD Intel adapters with model numbers 5xxx 4xxx and smaller should work under FreeBSD (were reported to work under FreeBSD) - current FreeBSD stack has all necessary for these, you may need to fiddle a bit with installing latest firmware. This is as far as I know. You may want to check which WiFi adapter the laptop of your choice has. Relying just on the fact that some laptop is certified for Linux (they usually will like Ubuntu for it) does not guarantee that WiFi on that laptop will work under FreeBSD. Namely, all Intel adapters with model numbers 7xxx and 6xxx will work under Linux, but will not under FreeBSD. As far as I know, that is; somebody, correct me if I'm wrong (with the reference to how I can make Intel 7xxx or 6xxx work under FreeBSD). I hope, this helps.
