We do not have any control or access to the event logs. The logs you see in the event section are related to your internet service.

Check the status page for the downstream power, upstream power, and SNR (signal-to-noise ratio). This page gives some good info on what to look for:

If the downstream power, upstream power, or SNR are outside recommended ranges, you will likely experience connectivity problems.
