I’ve been looking for two small routers that are supported by openwrt with either a directional antenna or a removable antenna. It can be a 2.4GHz only model.
The TP-Link TL-MR3020 is apparently available at a few local stores but it’s EOL and I’d need to do the external antenna mod and replace both memory chips. Another option would be a Nanostation M2 or something along those lines.
If else fails, I’m strapping an old WiFi card to a Raspberry PI 3… But I want something a little nicer, and ideally with Mediatek hardware. I’m also a big fan of Atheros but their latest CPUs don’t have the best open source support.
