CAX80 Unresponsive / only shows power light

I recently came back home to a lack of wifi service. I went over to my CAX80 and saw that only the power light was lit. I unplugged everything and plugged it back in with no luck. Attempted a factory reset and start as if I had just purchased the router, but it will never get the "online" light to illuminate or broadcast a wifi signal for the nighthawk app to connect to. Attempted to connect via ethernet, but its unable to direct connect to 192.168.1.1 / .0.1. Looking at the ISP website, it shows no connection to the router despite plugging in via coax to multiple connection sites. At this point, I'm out of ideas to figure out how to get the router reconnected and downgrade firmware (may be the issue?). Any help is appreciated before I'm forced to go and replace the $500 router after 13 months of use.

    Are you able to access it if you go to 192.168.100.1?

    Do any of the other lights come on at all during startup?

      All of the lights light up initially, but then they subsequently go out leaving only the power light illuminated. I was unable to connect via 192.168.100.1.

        The hardest part is the cax80 has a boot loop. What that loop is is that during startup, if it doesn't detect a connection to the isp, it just continues to boot/reboot. 

        Sometimes you can access it when you're first starting it up and its looking for that signal. But its a narrow window. 

        If all the lights are turning on for a bit, usually its searching for that signal. Does it try to detect a downstream connection during bootup? 

  • My cax80 just did the same thing. Did you get it to work or is it junk now?

      Have you disconnected the modem from the coax line and factory reset the modem by pressing the reset button for 10 seconds then release and see if the front LED come to life? 

       

      pull the power adapter for 30 seconds then back in...

        Yes I've done those things. ( I haven't messaged those people). It doesn't work. Seems to be a prevalent issue that Netgear is running from. Honestly when I forget about the money I am about to spend to replace I'll be glad to be rid of Netgear especially after the fiasco of armor being renewed from Netgear and bitdefender. No more of that's them not us BS.

      Update. Talked with level 2 Eduard . Netgear is aware of the issue I have a new system coming soon. Kudos to the Netgear team.
  • I currently face the same issue. Is there any solutions?
    • PM DarrenM, he helped me connect with level 2. I have a new unit that just came yesterday and sent the bricked unit back today. Good luck

        Though from what I understood I was going to receive an orbi, but another Cax80 unit arrived so hopefully the same thing doesn't happen.
