Best setup for repeater operation
Greetings - I'm new here. I just got service set up and am suffering some issues with my intended operation. The satellite internet service is intended to replace a cellular mobile hotspot that I use at a remote location. The setup has a handful of internet devices, three of which are in a metal building that is 115 feet from the HT2010 (formerly hotspot). The devices include two Nest Protect units and a single 2.4 GHz wifi-controlled air conditioner that connects via the NetHome Plus Android app. The metal building barrier and the distance are overcome by using a NetGear EX7000 set up as a repeater. The repeater uses an outside coaxial cable-connected directional antenna with 20 dB gain pointing at the modem and a coaxial cable-connected omnidirectional antenna inside the building (it uses this second cable-connected antenna because the repeater resides in an intermediate room in the metal building). The setup worked fine when connected to the cellular mobile hotspot. After connecting to the HT2010, I was unable to get a reliable connection to the A/C and the Nest Protect units. The 5 GHz band never connected to the repeater, so I used the 2.4 GHz band. The EX7000 reported signal strength of about 50% in that band.
If the problem is not related to the double NAT, would you expect a third party router (I'm looking at TP-Link AX3000) to handle my situation better? If it is related to the double NAT, do you have any ideas how to determine this is the case?
