I just set up a testing lab of sorts with two TP Link CPE210's. I'm pretty pleased with the ease of deployment as far as I've seen, but there's nobody around me to actually form a mesh with. None of the other hams in my area seem interested, and the state of this subforum isn't encouraging either. I just figured I'd post a topic to see if anyone comes out of the woodwork.
I tried to stir up AREDN interest in Corpus Christi and had the same luck as you are having it seems. I'm on the Global Tunnel but have no local connections on a mesh.
I have to wonder if that's why the most active mesh is in Southern California, as the climate is much milder with cooler temps and far less rain and humidity.
