Thankfully, I have a RouterBoard 411 with a dual-band dual-chain card kicking around, as well as a Sextant antenna.
So I tried connecting my RB-411 to the 5GHz WiFi from home router (AC, 40 MHz channel, WPA2-PSK encryption). Eventually, it worked.
Speed went up from 30 at best with laptop's Intel AC7260, to ~90Mbps at best or around 80 Mbps average. Mind you, 411's are 100MFD cards and N-at-best to boot, and I am paying for 75/10, so YMMV - and for the better.
Here is the setup script you will need to run on a no-config defaulted card (should work on any 4xx, 7xx, 9xx and later cards running RouterOS 6.x - I am using 6.36.4), found through some trial and error, but is dead simple and works (Make sure to change any CHANGEME's to applicable):
