CM-STATUS message sent. Event Type Code: 22;

My Motorola MG8725 has started having connection errors in the last few weeks (CM-STATUS message sent. Event Type Code: 22;) and the downstream lock indicator begins flashing within an hour or so after rebooting.

I'm also experiencing intermittent connection drops, my main receiver, a X1 4k dvr does not show as online using Xfinity's online system check but 2nd receiver does and the dvr has developed the intermittent video black out that comes and goes.

My downstream power levels are much lower that they have been, ranging from 0.9 dBmV to 3.4 dBmV.

This isn't the experience we want, @user_48217a! The Xfinity app works great to fix many common issues if you even encounter a problem. Have you tried any troubleshooting steps using the Xfinity app

Yes I have, there really isn't a selection that deals with low power dropping downstream connections.

Today my downstream power ranges from 0.6 to 2.8 dbmv, just did a restart through xfinity app. 

Upstream are at 50 which I understand is normal,

Can I get help from your team that can measure these very low power levels or do I need to go through phone

support?  Obviously this is something beyond my control.

Also interesting the system check through xfinity support website give me this error checking my receivers,

System Refresh Unavailable

A System Refresh is currently unavailable because your main TV box is offline. Try restarting a single TV box to fix your issue.

I am watching tv on the main box now.

... MG8725 ... my downstream power ranges from 0.6 to 2.8 dbmv ... Upstream are at 50 which I understand is normal ...

Actually your downstream power levels are just fine (0 dBmV is perfect, target range is between -7 and +7), whereas the upstream levels are borderline (too high leaving no room for variation, target range is between +35 and +50 dBmV). Network connection problems like these are often due to poor coax connections or damaged coax cable, usually in or near your home. Running the cable through a surge protector, a defective splitter, or too many splitters can cause signal problems as well. If there is an amplifier in the line make sure it's getting power. 

If you want to troubleshoot this yourself, please see Internet Troubleshooting Tips. If you still need help, please post your Internet plan speed and the following information from your gateway (from http://192.168.100.1):

  • uptime
  • downstream: power levels, SNR (or MER), and error counts for all channels
  • upstream: power levels for all channels
  • complete event log, if available (Be sure to remove or blot out any MAC addresses. Forum security processing considers them "personal information" and may prevent the event log from posting if these are present.)

Copy and pasted text is preferred over images. Be aware that, if you post any images, your message will be made Private for a time, as all images must be approved by the Forum Moderators before the messages containing them become generally visible.

If you can't find the problem or you'd rather have Comcast take care of it and the employee does not help you here, call them at the phone number on your bill or 1-800-Comcast, or use one of the options on https://www.xfinity.com/support/contact-us/. It's not likely they can fix the problem remotely. If not, insist they send a tech out to identify the cause and correct it.

If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit (approx $100) unless you have their Service Protection Plan ( https://www.xfinity.com/support/articles/service-protection-plan, closed to customers that don't already have it). If the trouble is due to a faulty Comcast rental device or anything outside your home you shouldn't be charged.
