[c-nsp] OT: Wireless 2.4ghz

[Chris Evans]

I come across cheaper NICs out there that actually support 5ghz, but don't
support the DFS channels!  Heck even Google with its Nexus devices don't
enable DFS in the OS even though the NICs can do it..

DFS is costlier to implement so they go the cheap route.
