Run a pair of Ubiquiti Litebeam. If a WiFi extender is working then a proper p2p radio would work better.

There are purpose-built equipment for this.

1: P2P WISP such as Ubiquity Litebeam. the old Litebeam M5 is even compatible with 802.11 WiFi when airmax is turned off. My weapon of choice for performance.

2: Mesh routers. What seem to be the common man’s choice these days.

3: Routers that can do Repeater Bridge or Client/Station bridge mode. Easily doable with DDWRT firmware. I only.buy routers that can have DDWRT or OpenWRT because of capabilities like this. Super flexible. Netgear nighthawks and older linksys routers usually can run DDWRT.

4: “WiFi Extenders” or Repeaters with a LAN port.
