Please post a copy and paste of the modems connection status page.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
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.

You might disconnect the wifi router from the modem and then do a factory reset on the modem, press the reset button for 10 seconds then release. Just leave it and see if it connects and check the downstream LED. Should go solid ON.
Sorry - I have a correction - it is the Upstream status light blinking at a slow, steady pace
Check the user manual to see what the LED blink means. I believe it inidcates a problem or not working correctly.
Your event log shows criticals and errors, The ISP should be looking at this. Modem seems to have some problems getting some good services from the ISP. Might have a tech come on site and you can show him what your looking at as well.
I agree - I handed the Event Log to the technician yesterday and he ignored it because his tool that he plugged up to the Coax and to the Modem showed everything was operating properly.
I also checked the Manual and ironically it does not have anything for a Blinking or Flashing Green Downstream or Upstream - all it mentions is Amber or Green and Solid or Off - LOL
