    Ok,
    
    The event logs show some Warnings and Criticals that the ISP needs to review and resolve in this log. We can't do anything here.
    
    The power level are kinda low but in specs:

    The ISP could help raise them some.
    
    Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
    
    I see some Correct and Un-correctable values here which should be all reading Zeros.
    
    You may need to ask the ISP to help on this as well:
    
    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.
    Start with removing any amplifiers, signal attenuators, or splitters from the coax.
    From there check the line for kinks, damage, moisture in the line.
    Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
    Some of this should help with betting the correctables and un-correctables down to zero.
