How to activate new gateway without app

I received a new gateway, to replace a problematic unit. I have installed it into the network and attempted to contact Xfinity to get a new equipment activation ( I do not own a device on which I can install the app).

Your automated system reports there is no new equipment to activate then prompts me to perform other tasks.

The new gateway does respond to browser attempts to connect, with username/password prompt, but I am unable to proceed further.

Please advise.

I'm not sure if this method works anymore (YMMV). Try calling 1-855-652-3446. That is their self-install device activation line. Have the RF / CM / HFC MAC address and the serial number of it handy when you call. Good luck ! Please let me know.

EG, thank you for the quick response.

I contacted that number, and several others, and was informed by the autobot that it detected no new equipment to activate.

After connecting power and the service feed, and waiting a few minutes of blinking status, the device status LED turns solid white. Believing this to indicate it is ready to accept input, I lauch a browser, head to the default ip, at which point authorization is requested. Using what I believe is the username, and the password listed on the bottom of the device, I enter both, but am then informed that either is incorrect.

With the autobot unable to detect any new equipment, I suspect I have not performed some initial setup step correctly.

The invalid login also bothers, unless the password is the old default, which I have not yet attempted.

Advice?

I'm going to escalate your issue to the Comcast corporate employees (The Digital Care Team) who are available to these boards. They should be able to provision the device remotely. You should get a reply here in your topic. Good luck !
