Experiencing intermittent loss of our internet connectivity
See here for a simple diagram of the system configuration
At this point I believe the issue is with the connection from the source lines along our street to the house, through the splitter / booster, to the modem perhaps confounded by variation in the source signal strength. That is, the modem is not receiving a consistently strong enough signal to establish and maintain connection and cannot recover one when it is lost.
I have a home office, separate standalone structure, on our property that is ~ half the distance to our home from the street. That has a separate internet connection and account, with a similar setup – 3rd party modem (Surfboard) and WiFi router (Linksys). I have had zero issues with connectivity. The home office setup is newer in this regard (buiilt in 2015) and a shorter run (to the extent that makes a difference)
I am not a networking expert… I do however have a long history and deep background in electrical / mechanical / systems engineering and software…. so pretty sure there is a way to diagnose, debug what is happening with the signal from the source connection to the home, directly with some diagnostic device / tool I don’t have (presumably Comcast or it’s vendors, others do) or indirectly through whatever logs the modem is putting out and whatever tools exist to make sense of these…
Much appreciate any help here!
