Xfinity is my provider and all I can get is the top COAX WAN lights
I am having the exact same issue! Xfinity is my provider and all I can get is the top COAX WAN lights. I have done everything, all the resets, all the power-offs. Even the 30-30-30 reset (which I did for 60-60-60 a second time just in case). Any ideas? Could this be linked to last month's CAX80 firmware reboot issue? Sadly, no warranty RMA for me... No wifi, even wired doesn't respond. I'm all ears...eyes?

Please post a copy and paste of the modems connection status page.
What FW version is currently loaded?
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.
Be sure to power OFF the modem for 1 minute then back ON.

https://www.duckware.com/tech/solving-intermittent-cable-modem-issues.htmlOh yeah... the tech came by Sunday morning (Jul 17) and this situation is wild. After testing the coax line she was on the phone with someone (engineering team?) After about 1 hour she made an engineering ticket. I don't use the Xfinity line for anything but my modem so it comes straight from the wall box into my modem, no splitters or anything. Signal is great. The modem is successfully connecting to Xfinity for 5-10 minutes before restarting... endless loop.
My hope is that Xfinity will push out a new firmware flash to me because there is not a reset I have not yet tried. They claim that isn't something they do for customer devices but we all know they do ninja flash our CAX80 firmware 2-3x a year.
My issue seems far worse than most other people have reported. There is no router page I can even access. No wireless is being broadcast (I did try the front wifi button). No wired connection works, like the blinky port lights don't even blink when connected. Both PC and Mac report no connection. I have many known good CAT6 cables so it isn't the ethernet cable.
Firmware is (was?) 2.1.3.7

The only FW that users can NOT apply to the modem is the modem portion of FW. There is user updatable FW for the router portion of the Modem. ISPs ARE responsible to push FW to the modem side of the modem.
The reboots of the CAX80 inidicate that the signal on the line has dropped to a bad level or is no longer present on the line, thus is triggers the CAX to continually reboot until a signal on the line is present and working. The ISP needs to look into this.
Do you have a screen capture of the Events Log and Cable Connections status page?
