CM1100 Channel Lock lED keeps blinking????
Why does this led keep blinking with my Comcast Xfinity internet connection. All seems fine with my internet connection and speed, and there appears to be no channel locking problem.
You have line issues. You have errors in your line and your event log is showing ofdma profile errors.
The profile issues might not cause issues as your connection is a 500mbps connection and not faster (don't necessarily need a docsis 3.1 connection for those speeds with xfinity).
So it might connect and work fine but with all your line errors I'd be looking at it closely.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
If you can, simply connect the modem right where the coax comes into the home. This prevents wiring in the home from being the issue. And some ISP’s charge if the wiring issue is in the home. So this helps prevent this.

Screen snip from the manual attached. If your connection is performing as expected, the blinking LED is nothing major to be concerned about. Looked at your event log and again nothing to be concerned about. On your cable connection there are a lot of correctable/un-correctable events noted. To put those in perspective, would have to know your modem system up-time. If you recently restarted your modem, they are not good. If it has been weeks or months since a restart, most likely nothing bad. These values reset when you restart your modem.
