WiFi Connection to Desktop Drops Intermittently

After receiving a new Xfinity modem, for some reason the WiFi connection to my desktop PC drops intermittently. I can be working for several hours with no issue, and then all of a sudden the WiFi connection drops. I cannot just reconnect to the network, and I have to reboot the PC in order to connect again. I'll then be good for another couple of hours, but the connection will invariably drop and I'll have to start the whole process of rebooting over again. Never had this issue with my old modem, so I feel that is somehow the problem. Any thoughts?

Thank you for visiting our official Xfinity Forums Community support page @user_occg5f. We can certainly assist in troubleshooting the Xfinity Internet service. We certainly know how important it is to have a reliable Internet connection from working from home, online schooling, and basic entertainment needs. Let's go ahead and take a look at some things.

I see that you are having issues with the computer specifically. Are you also experiencing issues with other devices within the home such as a cell phone, smart TV, or other electronics? 

When the computer happens to go offline, could you please tell us what the LED status on the Xfinity xFi Gateway is doing? Is it on, solid, or flashing? Our 'What the lights on your Xfinity Gateways mean' support page goes over the LED status and colors. This would be a great help to know the status of the modem while the issue is taking place. 

Do you also have our Xfinity App on your mobile device? Would you also be able to check the status of the Xfinity xFi Gateway within the app to check the status of the modem to see if the device is online? This will be enormously helpful for troubleshooting further. 

We hope to hear from you soon.
