Help troubleshooting 1200 internet with a fraction of that actually being delivered.
I am using an Arris T25 modem, on the approved list from Xfinity. It is DOCSIS 3.1 and should be able to deliver the speed.
Yes, I've rebooted the modem. Rebooted my Wifi. In fact I recently updrage my Wifi to a Wifi6E AP and the performance hasn't improved so it must be something on the Comcast end.
I have seen speed tests up to 600Mbps at times, but it is usually 200-400Mbps.

Comcast/Xfinity does not approve the T25 for Gigabit Internet service. They rate it for wired download speeds "Up to 949 Mbps". Using devices on Internet speed tiers for which they are not approved tends to produce unexpected results, often speeds well below the ones you are paying for. See the "All Compatible Devices" link 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/2024.08.14%20Full%20List%20of%20Compatible%20Devices.pdf, but this changes from time to time).
Realize that although Comcast calls some devices "Compatible" and some "Recommended", for all but a few devices those designations only mean "compatible/recommended for use with their Internet service", and not necessarily "approved for your Internet plan".
Comcast could make all of this much clearer, but they have chosen not to do so.
