Hello! After plugging the router into a location with LTE signal and an AC outlet, I can confirm it was actually a power issue. For whatever reason, the modem (but not the router) was rebooting due to power. I don't know if it was power variance and low voltage.I was getting consistent 18v at modem install point. I thought that would be enough. Though the issue is fixed for my current install location (AC outlet near), would you like the troubleshoot file for when I have installed in the POE location with 18v? I can install it there later this week to get the file.
