No internet for 5 days or the connection goes in and out

I am having this same issue. It’s a never ending cycle with Cox tech support. They ask me to do the same things over and over again, and expect to get a different outcome. It didn’t work the last five times, why do they think it will work on the sixth try. It’s insanity. I’ve never had an issue until I recently switched to the Gateway modem. Maybe it’s just a coincidence?
