I have had the same issue. It worked well for a few days no issues and now we have to keep powering down modem and restarting it for the connection to come back. There are no issues with my internet provider and have never had to restart modem at least twice a day.

Could you please let us know who your internet service provider is and the internet speed plan you are subscribed to?

By connecting the modem directly will help us to isolate the problem that if the internet drops on the Wi-Fi router or with the modem when connected to devices like a computer.

And checking the cable signal levels would be the best course of action as cable signal levels in modems refer to the strength and quality of the signals being received and transmitted between the modem and the Internet Service Provider.

Please find the below link, where you can steps to check the cable signal levels.

Lines do sometimes have issues. Weather can impact it too. 

Log into the modem and take a screensnip of the cables connections page (shows upstream/downstream values) and the logs. That helps check the line/connection for issues.
