Is there an open-source type device out there, like the Raspberry Pi, and in the same price category, but with a good WiFi implementation (i.e. external antennas). I've been looking at the Banana Pi offerings they seem like great hardware but it seems there is no official OpenWRT support for the newer models (RPI 3 Mini, Wifi 6 Mini for example).
I'm trying to deploy an all-in-one WiFi AP VPN tunnel device and finding my options quite limited. Anything x86 you run into problems with the WiFi cards and drivers, RPi has poor wifi, BPi poor OpenWRT support... any tips where to look?
Should support WiFi5 (AC), external antennas, mainstream OpenWRT support and cost under $30. Is this a pipe-dream? Lots of things come close but none are quite there....
