Thanks for taking the time to post on the community.
My apologies that you are experiencing issues with your broadband connection.
I've taken a look at your connection, the upstream power levels are locked onto one channel and running too high at 58 dBmV. As this can have an impact on your broadband, I would like to arrange for an engineer to check this for you. I've sent you a PM (purple envelope icon, right corner) requesting some details.
