I have an S33 modem and I am trying to identify if my internet outages are due to the modem, my provider, or the cable to the provider.  I saw a post stating that posting logs could help identify this.  When issue is present, the modem is not fully syncing with the provider and is showing a -26 to -37 dBmV for power for downstream.  When it functions the level is -12 to -15.  Part of log is below when issue is seen.

The modem itself is unlikely to cause an internet outage. The issue might be due to maintenance work in your area or poor signal reception from the service provider.

Event logs are typically related to the internet service provider.

If the modem is losing connection, it could be because it is not receiving a proper signal from the service provider.

For your reference, please find the link below to check the cable signals.

Cable signal levels are crucial for maintaining a stable and efficient internet connection.
