Second, if you are seeing upload issues, it could be an upstream signal problem.

FWIW, due to the way TCP ACK (Acknowledgement) works, upstream / return impairments can affect the downstream as well.

True but ACK packets are normally much smaller than upstream data packets so unless things are really bad, they are less likely to be affected.
