WindowsKey+R

Type at the command line: ping 192.168.100.1
Press

The ping command sends a short message to the specified host and asks for a return message.

When the internet drops out ping the modem (which should be visible).
If you can see the modem and not the web, it's comcast. Ping will say "Reply..."
If you can't see the modem, it's your LAN, maybe the mesh router. Ping will say "Request timed out."

It's probably the comcast service. That's my guess.

Now before you get into any of that have you replaced the Ethernet cable between the modem and router?
