CAX80 lights on but no internet
Hello, I’ve checked over everywhere I could find because a few hours ago my lovely CAX80 decided it wanted to start cutting out about every 5-15 minutes. The lights on the device stay on but I get cu...
You have tons of correctables and un-correctables on the line. Those should be mostly zeros there.
Power levels are with in specs.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly. You should get a tech on site.
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.

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.
I’m not currently home but I figured you might ask for that, this is what I took last night before I went to bed

I’ll start by swapping out the co-ax cable when I get home as I have no splitters or amplifiers attached to it, then if it’s still occurring I’ll turn to isp and if it’s still happening I may reach back out, thank you for the responses.
For the collectables and uncollectables are the lines you’re looking at the ones directly underneath those words where there’s numbers 1-32 and locked respectively?
Might have the ISP let you use one of there gateway modems for a time and see if that changes anything.
Yes.
Not sure what exactly fixed it, which to be honest I hadn’t tested hitting enough to be sure but there was xfinity maintence that occurred near my area while I was at work today and after I got back I gave the CAX80 a reset and it flushed the correctable and uncorrectable down to zero with minor variance. Just to be safe I swapped out to a new co-axel but I’m gunna go ahead and list what you gave as the solution because at the end of the day I think it did just come down to the isp needing to do something. Regardless thank you for the answers and if it starts acting up again I’ll make a separate post but fingers crossed it’s over.
