My internet connection keeps dropping all day. I had a tech come out but there was no change. I bought a new modem and a new router. Same result. When calling on the phone the modem kept restarting on its own. She said it was a signal problem. I am so annoyed. She wants the tech to come out again. This has been happening for a month now.
If you have another Cox jack in the house and it can be used for the modem, try that.
