Judging from some things on FreeBSD forums, I'm not sure that dual card laptops work that well withTrueOS (or any of the BSDs), but am not sure. I see someone was having problems with CURRENT, which is what TrueOS uses as a base if i'm right.

General thoughts. Both Free and OpenBSD are usually behind Linux in hardware support. While a wireless card will probably work, it often won't have the speeds that are gotten with Linux--for example, the iwm driver doesn't do 802.11.ac In practice, I've found this means that a local LAN transfer might be 20-50MB in Linux, on occasion, 11-12 MB in CURRENT (but rarely) and generaly, in Free and OpenBSD about 2-3MB.
This TrueOS posting from last year might be useful.
