Multiple Errors on my Docsis 3.0 model with Cox
I have noticed some speed issues with my Cox Internet connection so I logged in to look at the logs on the modem and found the following errors which are repeating every day. Before I call support and get told nothing is wrong I was hoping for some expert direction from the collective within the forum.

The signal levels reported look good but the T3 error counts are elevated suggesting the modem is having trouble communicating back to us. Are there any cable splitters you can try bypassing and seeing if that helps?
