Welcome to the Community!
Really sorry to hear you're having trouble with your connection.
I've run diagnostics on your equipment and I can see an issue with your Downstream levels. This is likely what's causing your connection issues and will need to be adjusted by a technician.
I've sent you a private message (purple envelope at the top right of your screen) so I can arrange an appointment.
