My ISP says nothing is wrong and the Netgear tech support is no help considering I'm outside my 90 day purchase window.
The cable connection error is with the cable connection continuously failing to connect. I've used new cables and moved it to other cable ports in the house known to work in the past.
Please help.
- Yes. I've done a cache clearing reset...removing the coax cable, holding the reset for 30sec, and power cycling 3 times in a row. Same error.
Has a power OFF for 1 minute then back ON with the Orbi system been performed since last update?
You only need to press the reset button for 15 seconds then release...
Please post a copy and paste of the modems connection status 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.Has a power OFF for 1 minute then back ON with the Orbi system been performed since last update?

- I did a "shock" reset w/ a netgear tech which was the 30-30-30 reset according to the case number.

Be sure your using good quality RG6 coax cable up to the modem.- ISP on-site technician performed all these actions, and nothing is wrong on their end.
I've been in contact with NETGEAR and they're going to send a replacement device. My ISP installed a temp router so I won't be troubleshooting further. I still believe the firmware was the root cause, but I can't say why/how a firmware update would break the modem.
