I've used OpenWRT in different incarnations over the years, and at this point my suggestion is to forget about OpenWRT and buy some Unifi hardware from Ubiquiti. You get almost the same amount of control from Ubiquiti's pro line, plus the hardware is really solid and it all Just Works.
Now that the enterprise-level Ubiquiti stuff is so insanely cheap, there's basically no reason IMO to fool around with open-source router projects.
