Hi All

As mentioned in the title, my signal has been dropping very frequently over the last several weeks. I’ve contacted my ISP (cox) and they gave me the run around (reboot your devices). I’ve also contacted Arris last night and the suggestion I received was to ask my ISP to increase the power on my upstream channels to which the cox tech had no idea what I was talking about so here I am… I’ve factory reset my router, I don’t believe that’s the issue. I’ve done a little research and it seems having high uncorrectables is an issue, this screenshot is from today after i reset my modem 12 hours ago. thanks. I purchased this modem and my asus router both a year ago and had no issues until recently.

Your logs are indicating line issues and so is the cable connections page. 

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.
If you can, simply connect the modem right where the coax comes into the home. This prevents wiring in the home from being the issue. And some ISP’s charge if the wiring issue is in the home. So this helps prevent this.

You might have to contact cox again if that doesn’t help as the line is the issue.
