Losing internet access every night

Sometime during the last 6 nights I have lost internet access. 1st two mornings, I reinstalled HT2000W. 3rd, rebooted. 4th, unplugged for 30 seconds. 5th, rebooted. 6th, reinstalled. I should not have to fiddle with the router every morning to have internet access. Called support and spoke to a moron who understood nothing. She said it showed I had been turning the router off and on and I shouldn't do that , because it could damage it. Had to explain, again, I had to in order to have internet. The router should have been replaced a very long time ago. I have lost ability to connect to hug2 through laptop. I have sporadic signal that during downloads speeds drop to zero and sometimes stay there. She finally told me to call when the issue is present. YOU KNOW WHAT HAPPENS THEN?? Faulty diagnostics will be run. I will be told to unplug and replug, then it will work and I wil be asked, "Thank you, is there anything else I can help with?" Support quoting FAP (which means if you want higher speeds throughout the month you should be able to afford $500-$1000 every month), does not help and does not have anything to do with my issues.
