Disconnecting after starting up PC

Good morning @user_5hud5b, and thanks for posting your issue to the Xfinity forums, I hope this message finds you well. As someone that uses a PC as my primary gaming device, I can understand the frustration of having an issue with the device dropping connection, but you have reached the right team for assistance with this issue. Is your PC connected to the internet via a ethernet cable, or over WiFi?
