Frequent disconnects and dropping of connection with XB8 gateway

Hello. We recently got the newest XB8 modem and have been having internet connection dropping issues ever since. We do not know what it is. We have had 2 techs come over, one set up a new internet box outside our house and the other came the next day after I was still having issues and we are still experiencing issues. It will stay online and have a solid white light then all the sudden, go to a solid orange light then a blinking orange light and it will repeat this cycle at any time usually after 10 min to a few hours. As I said, we have had 2 techs come over, I have talked to about 10 agents, and nobody can identify the issue and we are currently paying for this connection dropping internet. This only started happening when we traded in our old modem for the new XB8. Help would be very very much appreciated
