Not sure about Cat5 but we've been in McClure since march 30th we have Comcast xfinity for internet $45 unlimited with 2 of us using tablets plus streaming Amazon or Netflix with no issues. What speed I can't tell you but it hasn't lost the connection yet. We have a dish contract so we're with that for at least 8 more months. 3 times we've lost the signal. The 6 ends in the cable/sprinkler box had connections put on when tech came to the home.
