Greetings. My home media service is with Comcast and I am using their ARRIS TG1682G cable modem. The number of devices I am connecting to this device has grown leaps and bounds via direct connection to the router and a pair of gigabit ethernet switches. One of the connected devices is a whole-house generator we recently installed that is networked and continuously monitored so that I can access it via my laptop and a phone app. Several times a week I am getting alerts that I have lost network connection to the generator, sometimes for a few hours. It has, so far, self-restored. I'd like to troubleshot the problem and thinking to start by setting up a network monitoring tool to learn if my router is the culprit. I'm not particularly pleased with several aspects of my home network and wireless performance and would like to see if I am creating my own troubles. I know there are some smart network folks here and would appreciate a (hopefully free) monitoring software recommendation and perhaps some other advice, hopefully also free. ;) Thx!
