If so, go to ip ipdress/debug.htm for example: 192.168.1.1/debug.htm
uncheck the logging/packet capture.
i've found it enable after rebooting mine and it'll work great for a period and then lockup/drop. With that unchecked, it works fine.But for some reason, whenever I reboot, its rechecked.
plemansGood catch. I've been experiencing slouggish performance and disconnect issues after a few days. Usually, between 4 to 6 days. Rebooting resolves the issues sometimes, but at other times I have to reset and restore the router. See my recent post in this thread where I outlined the issues that I've experiencing with the CAX80 connected to Spectrum. I tried contacting one of the Moderators via private message to see if I can get a hold of the beta firmware release (v2.1.0.4), but I have yet to receive a reply. I tried calling Netgear Support, but I have not found the time wait on the phone to get a hold of a 2nd level technician. Hopefully, a firmware update that fixes some of these issues is in the pipeline and will be release soon. I feel like I paid a lot of money for a router that has to be rebooted every few days. Before this router I had a Netgear WNDR4500 (N900) that I purchased in 2011 connected to Spectrum via a Motorola/ARRIS Modem model SB6183 that I purchased in 2014. I only had to reboot this setup may once or twice a year, Including reboots for firmware updates.
My believe is that there's a memory leak in the current 1.1.0.41 firmware that is eating away at the available RAM storage of the CAX80 router. I'm going to disable the LAN/WAN Packet Capture option on that page to see if unchecking this option resolves the issue. Capturing and saving all these packets "could" produce a symptom similar to a memory leak as the router runs out storage to save the captured packets.

I also noticed when it was enabled the cpu was pegged at 100% for both cores. That can degrade performance as well.

Hi plemans,
How do you view the Memory and CPU usage of the CAX80? I don't see this info on the Admin page of the device.
Thanks

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 them back ON.
