Mesh Router Next to Telescope

If you control your telescope via WiFi (as I do), a solid connection is essential. Cloudy Nights is filled with complaints like, “My telescope keeps dropping its @#**## WiFi connection!!!”
When you mount a miniPC (or ASIair) on the OTA, you’re asking for trouble. The computer (with its wifi transmitter/receiver) is set on top of a metal tube slewing in different directions, surrounded by a dozen or so cables carrying signals and/or power, some of which may not be properly shielded. It’s no wonder that such computers often drop WiFi signals.
Assuming you’re observing from home, the best way I’ve found to avoid problems it is to use a mesh network and make sure you place one of the mesh nodes very close to the telescope. When I used to observe off a deck, I placed a node in the kitchen just inside the house about 10′ from the telescope. It worked just fine.
On my pier, which is 75 feet from the house, I buried a Cat 6e cable that connects a mesh router in my office to a waterproof junction box at the base of the concrete column. When observing, I plug a mesh router into the junction box, establishing an Ethernet back-haul into my home network and a super-strong wireless signal for the control computer. It too works perfectly.
My router OEM does make a certified, weatherproof outdoor node, but it costs around $200. I took my $20 Walmart special node and sealed it in a food container for dew and temp resistance. Its power-supply generates a little heat and is completely weather-proof. Works perfectly, even on cold, dewy nights.
