New customer modem setup (Arris CM8200) - Issue with activation

Hi  - I'm been through multiple chat agents and spoke with a couple of folks over call, but this issue is still not resolved. I purchased a new modem and agents confirmed its been activated but i still don't have internet at home. It's been almost 10 hours I have been trying to get this fixed. When connecting to Wi-Fi I get the Xfinity landing page asking me to activate the modem. A couple of agents on the chat mentioned something about a missing boot file. Any help you can provide would be appreciated.

... Arris CM8200 ...

Is that a typo? The CM8200 is not included on their recommended/compatible lists at 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/2024.09.18%20Full%20List%20of%20Compatible%20Devices.pdf, but this changes from time to time).

@user_s07x9g Thank you for reaching out to our forum and @BruceW I appreciate you jumping in to help :). Is your modem the Arris SB8200? I'd like to check your account to make sure your location is active and figure out why your modem doesn't have a boot file. 

Please send a direct message by clicking the chat icon in the upper right corner of the page, click on the pen and paper icon, then enter “Xfinity Support” in the “To” section. Please include your name and address and I'll be happy to help.
