Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem. Thats on them.
Please post a copy and paste of the modems connection status page.

Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
What is the brand and model of the host wifi router connected to the modem?
The Cable Connection Status is Good
My Router is Synology RT2600ac with a mesh Synology MR2200ac in another location.
The cable is labeled Cat 5e
Are you saying you think the problem is not the modem, but the communication with the router?
Thank you.
WE need to see that data from the cable connections page. There is a long page there of data that you can copy and paste here in the forums so we can see the values there. Help to determine more if this is a signal issue rather then a modem issue. Many factors on the ISP signal can be a cause of modems not working right. The events log points to that already.

Ok, signals and power levels on the line look good. Correctables and Un-correctables are zeros which is good.
The ISP needs to take a look at the events log and resolve those items mentioned.
