Another thing to check is the wiring to the house. If this is a cable company, it is likely that the cable to the cable modem splits off to the TV(s). Make sure there are not any unterminated co-ax cable which used to go to a TV. Make sure the cable outside the house is not damaged. The cable company can test for bad cable at your location. They may charge for this. You could get a length of co-ax and swap it in in various places to see if the problems go away.

if you have multiple splitters, make sure the cable modem is on the 'first' one, and that splitter is a high grade 2-way one. Make sure all cable is high grade RG6 quad shield and not older RG59 or whatever.
