"slow" internet download speed
I am suppose to be on the 1200 Mbps plan and yet when I run a speed test (thru Comcast or another site), I only get about 280 Mbps. My PC is directly connected to the router (Asus RT-AC5300) and my modem is an Arris TM822. No one else was using my internet connection when I ran the test so I am mystified as to what may be the issue. I appreciate any offered help beforehand.

The TM822 is not compatible with Gigabit+ internet service. Comcast/Xfinity rates it compatible with plan speeds "Up to 286 Mbps". See the link to the "All Compatible Devices" PDF near the bottom of https://www.xfinity.com/support/devices (at the moment it points to https://assets.xfinity.com/assets/dotcom/projects/cix-4997_compatible-devices/2024.09.18%20Full%20List%20of%20Compatible%20Devices.pdf, but this changes from time to time).
At present the only retail modem compatible with Gigabit+ and Voice appears to be the Netgear CM2050V.
