TP-Link 5GHz N300 Long Range Outdoor CPE for PtP and PtMP Transmission | Point to Point Wireless Bridge | 13dBi, 15km+ | Passive PoE Powered w/Free PoE Injector | Pharos Control (CPE510) White

I’ve down this as well and used one of these https://a.co/d/0cbtEAb3 Worked like a charm

I bought a tp-link because it was cheap and quick on Amazon. https://a.co/d/00GqzmN0 It’s rated for outdoor but I just zip tied it to a lamp inside the guest house next to a window pointing at the main house. Let it join as a client and got @ 200-250mb throughout I believe. Nowhere near the 1gb of the main house but good enough that they had someone use it for their work when staying there for a week.
