My Xfinity cuts out frequently

We were experiencing a lot of internet outages so we started by replacing our older Arris modem with the NetGear CM1000. There was a lot of issues connecting to Xfinity and they sent out a tech who replaced outside lines and removed one 4-way splitter with a 2-way of which we only use one line so he capped the extra.

Now a few months later we are losing connection almost hourly.

Here are some screenshots of our modem and error logs when it is online.

I appreciate any help. I can't imagine it's the coax because we just had them out.

    lots of errors in the line and the logs. 

    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.

    If that doesn't help, they need to check it again.
