CAX80 - Suddenly Won't Connect

Yesterday at 3AM we randomly lost wifi to all devices. I have tried multiple hard resets. When you reset, you gain wifi for about a minute, and then it quits again. It's not even long enough to login...

Can you access the modems web page? If so,

 

What FW version are you using?

 

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.


Be sure to power OFF the modem for 1 minute then back ON.

    I just kept restarting and it finally works again. When I would reboot, the 2.4 and 5 lights stay lit (don’t blink) which is when I know my reset attempt didn’t work. So something is blocking the WiFi signal from going out which makes me not able to connect to routerlogin. Now I’m back up and running (for no logical reason) and I was able to pull the event logs so I’ll post those as well. Also, firmware has been up to date since the problem began. Any thoughts?
