The internet speed is way slower than my Plan
Hi,
I activated my 2000Mbps plan yesterday, which is expected to support the upload speed up to 300Mbps.
I've been tested it multiple times yesterday and today. The download speed is at the range of 100Mbps-600Mbps, while the upload speed is only 6Mbps consistently.
Note that I also use an ethernet cable to connect my laptop directly to the Modem and tested it wiredly.
I am using the Netgear CM2000 Modem which supports up to 2.33Gbps speed, so it should not be the bottle net.
I used to use the Comcast business "Business Internet 100" plan and it has not been terminated yet (it's out of custom service's working hours). I am afraid that it has something to do with it. How can I resolve this issue?
Thanks,
Accepted Solution

There are only a few retail devices on their "Next Gen Speed Tier" list that are compatible with the new higher upload speeds, and the CM2000 is not among them. See:
And especially 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/2024-07-18_Full-List-of-Compatible-Devices.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 the new upload speeds.
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. Also see the Reddit link, which lists the approved devices as well as other requirements for faster upload speeds.
Comcast could make all of this information much clearer and easier to find, but they have chosen not to do so.

Hello, ymyfish! Thanks for reaching out to us on the forums! I apologize to hear of the issues you are running into when it comes to your internet speed. Do you know what type of ethernet cable you are using? is it Cat5e or Cat6? Have you tried switching out this cable? Also, do you know what speed your network card supports on your laptop?

As stated, all the devices listed in the PDF are "compatible/recommended for use with their Internet service", but only the few Next-Gen models are compatible with the new higher upload speeds.

All 1 Gbps Ethernet devices are limited to a top speed of about .94 Gbps (940 Mbps), so that adapter will limit your top speed to less than half of the 2 Gbps speed you mentioned as your subscribed speed.
