Upgraded to Gigabit x2 Plan but only getting 40Mbps upload speeds.
Hello, I upgraded my plan to the Gigabit x2 plan but I do not get faster upload speeds and am still limited to 40Mbps. I've rebooted my modem 3 times and I can see that only 4 of the 8 upstream bonded channels are locked. Can you help me activate my expected 300Mps download speeds? I'm attaching a screenshot from my cable modem.

What is the model number of your modem or gateway? Only a few are compatible with the new higher upload speeds. 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/2024.08.14%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 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 much simpler and clearer, but they have chosen not to do so.
