Extremely slow internet during work hours
I've been working from home since the start of March, and my Xfinity connection has gotten progressively worse over time. It's fine in the morning (before ~10am) and at night (after ~6pm), but during the day it often becomes so slow to the point where it's unusable and I have to use "mobile hotspot" on my phone to get a usable internet connection. I've tried with Ethernet as well as wifi (both 2.4 Ghz and 5 Ghz).
I live in an apartment complex with probably 90 or 100 apartments total.
I'm on a 175 Mb/s plan and am using a Netgear C6900 modem/router (24 x 8 DOCSIS 3.0). The modem is on Comcast's list of approved modems.

The stats are fine. Going by your description, and seeing the latency figures, this sure sounds like a capacity / traffic congestion issue due to everyone being online at those peak usage hours because of the pandemic. If so, there's not much you can do about it except to complain.

I've tried... Xfinity support is not useful at all. They won't tell me if it's a known problem in this area or if they have any plans to increase their bandwidth or otherwise reduce contention. Not sure why I still have to pay full price for my internet connection if I can't even using it during the day.

A technician came past to take a look at the cabling and test the signal strength, which all looked fine. He basically said that everyone in the area is experiencing the same issues due to the number of people working from home, they're aware of it but there's nothing he can do about it.
