CM500 Modem is showing errors - log shows critical errors

Can someone help me explain these critical errors and time outs?

Your power levels are spot on. And you tend to get those errors when you first boot up your modem.

If you continue to get those errors repeatedly after using it for a period of time, repost the logs and the cable connections page.

Are you having an issue?
