Xfinity Internet Upload Speed Capped at 40 Mbps

First. Have you confirmed that your area has already upgraded for the new Next Gen / Mid Split speed tiers ?

You should have received an E-mail stating so. I'm going to escalate your issue to the Comcast corporate employees (The Digital Care Team) who are available to these boards. They will be able to check into this for you. You should get a reply here in your topic.

Also be advised that even if your area has already been upgraded, there may be a provisioning / speed configuration file / backend database issue. They can check into that as well. Good luck !

Hi there, @user_mbflux ! Thank you so much for reaching your Digital Care team. I appreciate your patience while you waited to connect with me. I'm so sorry to hear that you are not getting the speed you should be getting. Please be assured you reached the right person to assist you. Can you please DM me your first and last name, along with your full service address so that I can assist you further.-Richard

Please circle back here and post any possible solutions for the issue here in these open public forums so that all readers here may benefit from the exchange / info. This is in keeping with the spirit for which these public help forums were originally intended. Thank you.

Unfortunately, the issue remains largely unresolved.

Xfinity Support confirmed that my area is upgraded for upload speeds up to 300 Mbps. They added a code to my account on their end and restarted my modem, which allowed me to see upload speeds up to 60 Mbps, so we broke through that 40 Mbps barrier. But all the troubleshooting suggestions after that have boiled down to reconfiguring the WiFi (renewing IPs, connecting directly to the modem) or resetting equipment (restarting every piece of equipment), and none of that did anything to help. So I remain at 60 Mbps upload.
