CassandrichLazyweb, what's a decent wifi ap/router in the $50-100 price range that works painlessly with OpenWRT? Good antennas, decent speeds, and low power draw (long life on battery backup) are my main criteria. TP-Link would be my normal go-to vendor and I saw some praise for the Archer C7 which I could get for around $60 but I wasn't clear from the OpenWRT wiki if it's reliable.

@dalias Seems to be pretty popular and haven't had issues with it for many years, although few years ago I switched routers to a PC Engine APU6 (lot more expensive) so I could easily run any OS.
