Hi,
Very randomly, but typically at least once a day. My WAN connection will fail. Everything on LAN is still fine, but my cable modem (Netgear CM1200) reports no connection.
In the logs I typically see messages like this.

As far as I can tell, I only have a single splitter on my coax line. And I did try removing it, but nothing changed.
Can someone help me out?
