Internet dropping

I don't know if this is a 10 problem or computer problem. My internet will drop every few hours while I am using it. I originally thought it was my cable provider, and most of the time I rebooted my modem, and this seemed to correct the problem. Then I just rebooted the computer and it also solved the problem. Any idea - I do not think it is the cable.

Router as well or just cable modem? A combination cable modem/router? If you have another computer how it does on that. If they are connected through a router, how well do your device work when connected to the internet?

Just a cable modem. I only have one computer. Everything is hard wired
