Extreme Speed Drops in the Afternoon

Most afternoons my gigabit service  drop to unusable speeds. I work from home and upgraded my services and hardware several months ago. I can tell when the speed drops when my work applications no longer work.

 

On a hard wired computer my internet download goes from over 900mbps to 400mbps and my upload goes from 40mbps to under 2mbps (I get these speeds using 3 different speed test websites). I get the same speeds using the speed test on my orbi router which is plugged into the xfinity modem. I can do a speed test from my computer to my router and I have gigabit speeds on my internal network. 

 

I had a tech come out who replaced some outside hardware that was older but the issue hasn't gone away. I looked at my modem and the values do not seem off except the CM errors.
