CAX80 Multi-gig ethernet port dropping
I've upgraded to the CAX80 to take advantage of Xfinity's new 1200mbps speed. My PC has a 5gig ethernet port. I've already spent over 2 hours on the phone with NETGEAR support - with no resolution be...

I have the same problem, 2.5gigabit cuts out. I've done extensive testing discovered the flaw with the cax80 is related to the wifi. When the frequency of the 2.4 & 5 Gig wifi are at the lowest settings the 2.5 multi-gig port cuts in and out every several hours or so. If you set the wifi frequencies for the 2.4 and 5 gig radios to the max the 2.5 multi gig port cuts in and out every 5 to 10 minutes. If you disable the wifi radios, turn them off, the 2.5 multigig ports work fine. I get 1400+ mbs downloads on comcast. I have disabled the radios and use anouther, R7000 router, as an access point. Very shameful of netgear as i have had the cax80 replaced once and now out off warranty stuck with a lemon of a cable modem/router (cax80). Several others have noted simular problem on reddit.

I am really glad to hear I wasn't the only one. I ended up returning it and just ordered Xfinity's XB7 router/modem combo for $14/mo. It includes WiFi 6 and also a 2.5Gb Ethernet port. Been using it for a few months now, not a single problem!! I like to own my own eqipment and have since day 1... unfortunately the CAX 80 is broken.

Something to contact NG support about to let them know. Maybe a faulty unit as well. I've had mine since last year and have had no issues with it.

I am having the same issue as everyone else; except I did contact Netgear, they sent me another CAX80 and I have the same issue with that one as well.
If you factory reset, the issue goes away; but as soon as the firmware updates with the new security on it; the issue resumes.
Tested 2x CAX80s, 3x cables and 2 different hardwired machines; all same issue as everyone here.
Its surprising netgear has not fixed this yet as it has been happening for a LONG time.- FURRYe38Oct 11, 2021Guru - Experienced User
Well not everyone is having a problem with the multiGig port.
What device do you have connected to this port?
