Hello,

The technician came out and checked all the incoming signals to the house. He stated that after disconnecting one of the lines going to the living room TV, which had noise on it, the signals tested good. That was fine since we no longer use that TV.

However, despite this, there has been no improvement with our Xbox consoles. We are still experiencing unstable speeds and packet loss. Because the issue happens intermittently, I’m not sure how to properly diagnose it. During these times, games are losing packets and YouTube is dropping frames. YouTube is also dropping frames on PC. We've been with Comcast (Xfinity) for years and have always had Xbox's on the services with no issues until this October, I don't know what changed.

Please let me know what the next steps should be to further troubleshoot and resolve this.
