@John130 -- I doubt that Rogers has "touched" any of the previously-Shaw infrastructure (coaxial-cables along your street's telephone-poles, and from the nearest pole into the Demarcation box on the side of your house.
This forum is only a peer-to-peer discussion forum, where volunteers try to help. It is not a path to Shaw/Rogers Support. So, contact them: 1-888-472-2222 or www.shaw.ca/chat to get trouble-shooting help.
Maybe, your cable-modem is failing, and needs to be replaced (at no cost to you).
Can you temporarily disconnect your TV, and connect a different TV, to see if the outages are not being caused by your current TV?
