How do I view or clear the event logs on my NETGEAR cable modem or modem router? | Answer | NETGEAR Support

Check your cable and make sure there isn't any splitters. Technically your power levels are in spec and you don't have errors but you're borderline and the upstream might have more resistance causing it to not lock enough channels.
