Internet keeps dropping with DS Profile Assignment Change in Cable Modem Log

I am currently using a Motorola MB8611 cable modem which has been in service for the past couple of years without issue. My internet keeps dropping for a couple of minutes intermittently with the event log entry of DS Profile Assignment Change and then reconnects without me having to reboot the modem. Xfinity has sent a technician out to check the outside lines and reported no issues but is trying to put the blame on my internal network hardware ( TP-Link Deco BE63 BE10000). Only thing is when the disconnection occurs, all devices remain connected to the wireless/wired LAN and I am still able to communicate with my modem. JUST NO CONNECTION TO THE INTERNET from my ISP....Any suggestions on what next steps I could take?

What do the modem's signal status values look like ? Try getting them here;

http://192.168.100.1 


Please copy all of the text in its entirety of the *Downstream Power Levels*, the *SNR's* (Signal to Noise Ratios), and the *Upstream Power Level* numbers and paste them into your next post.

The signal status values were ok at that snapshot in time. Please post the modem's RF error log entries in their entirety (copy and paste all of the text), but redact the CM and the CMTS MAC addresses for privacy or else the forum bot will not allow your post to be seen publicly.
