Please Help

Hi! I've been experiencing intermittent upload instability for a long time, particularly when livestreaming.

I've confirmed that my computer can render and encode normally, but my streaming software experiences significant network dropped frames.

My local gateway ping tests show 0% packet loss, while external tests have shown 1–2% packet loss, including to a Comcast network hop.

Could you please check my gateway's upstream signal levels, connection history, and any intermittent upstream noise or errors on the line? I'd also like to know whether a technician should inspect the connection.
