Upload speed 20 Mb instead of the 100 advertised
Hello,
my upload speed seems to be much lower than what was advertised when I subscribed. I am only seeing 20 Mb instead of the 100 Mb advertised for upload. Can this be fixed or am I doing something wrong?
My modem is an Arris S33 and I own it.
Thanks!

The S33 is not compatible with the new higher upload speeds. Only a few retail devices are. See the "Next Gen" list at the top of 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).
Also see:
You need one of Comcast's newer rental gateways (XB6, XB7, XB8) or one of the few retail devices shown in the "Next Gen Speed Tier" group with an upload speed rating in the "All Compatible Devices" PDF:
The Reddit link lists the approved devices (although that list is out of date) as well as other requirements for faster upload speeds.
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 the new upload speeds.
Comcast could make all of this much simpler and clearer, but they have chosen not to do so.
