Please post a copy and paste of the modems connection status and event log 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. 
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.

Update:

I attempted to get a log, I am now unable to login to the orbi. Every time I enter the username and password, it tells me to reset the password…

As I mentioned in the original post, all lined up to the orbi have been tested and confirmed good by the ISP.

    Be sure to clear out all browser caches before entering the modems web page. 

    Try a different browser to log in. 

    Will need to review the cable connections and event logs pages here.
