No Internet on CM700

Question

I am currently unable to connect to the internet on my CM700. I haven't had any modem issues prior to today, but this morning I was unable to connect, even after restarting the modem several times. I have a two-way splitter, but still wasn't able to connect to the internet after removing this. Cable is working fine and when I plug an ethernet directly into the modem, I connect without issue.

I have gone through the Error logs and have the below error messages.

I have also checked the up/downstream specs:

Does anyone know the solution?

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute them back ON.
