I have my computers and other things hard wired to the internet. Cable is underground, it comes up under the house and into the center of the home. Back to old school security.
I thought Dale Gribble was dead...
You are fortunate to have your cable routed under the house. My cable is all underground but, it has to come above ground to connect to the required ground rod and the distribution box on the outside wall with the cable runs to the rooms in the house. If I were to reroute the incoming cable under the foundation and into the craw space, it would be a major task. Having that distribution box relocated into the crawl space would be a task. I am not sure if Comcast would want it located in the crawl space when they have to replace those metal end connectors and splitters when they become corroded.
