CAX80 Updated to Firmware 2.1.3.5
This morning I was presented with Firmware Update 2.1.3.5 for my Netgear CAX80. After thinking it over for a couple minutes I took the plunge and installed it. The Firmware Update installed fine, but...
Comcast tech just left. The signal coming into the house was apparently extraordinarily strong. He added some kind of step-down attachment onto the coax connector that balanced the upstream vs. downstream power a little better. CAX80 is now reporting a good signal.
So the new diagsnostics weren't in error. They ID'd a legitimate problem as intended!
Have them check the modems connection status page for signal values while they are there.
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.

Thanks, tamanaco. Good to know. A Comcast tech is scheduled to be out here sometime in the next two hours to have a look at things. If your diags are working correctly, then it's likely a valid issue with my coax run/provisioning.

Glad they got it working.
Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.

Enjoy.Anyone have any ideas why downloading the latest CAX80 firmware 2.1.3.5 and attempting to apply as documented isn't working for my device? The message I recieve states "This firmware file is incorrect! Please get the firmware file again and make sure it is the correct firmware for this product". And yes I downloaded the compressed file and unzipped and pointed to the CAX80-V2.1.3.5.bin file, several times now with the same result. I also tried using the GUI firmware check and get the message, "Unable to download firmware from Netgear server". The only thing I can think of is that Cox is blocking the update at the moment at least for the latter attempt.
Any thoughts?
See screenshots.
Thanks.
