Thanks both for advice, the cables seemed solid but I've taken them out (both the hub and tv box and the port into the house) and put them back in again as suggested, the coax's are 100% secure in place and seem fine. Just letting everything power on and settle and will post in an hour or so with the new logs if its still wonky.
It would also do no harm to setup a BQM to monitor your circuit in the future, and it's free !
VM will, in most cases, suggest you setup on anyway, so it's a handy thing to have running.
