netgear nighthawk cax80 multi gig port keeps dropping connection

Does it happen using the standard ports?

Have you tried a different device connected to the multigig port?

Reason I ask is I had a qnap 10g controller that did the same thing. It'd drop multiple times throughout the day or with specific programs. It was a bear to troubleshoot as it ran fine on a 1gig line

Hello

So this issue with the multi gig port dropping connection has me a bit frustrated because I can't figure out what is causing this issue. I have tried different Ethernet cables cat8, cat7 and I currently have a cat6a stp plugged in. The drops of internet are random throughout the day from a couple a seconds then it comes back and some days I have no drops. this issue has been going on for about a week an half. I recently build a new pc were the muti gig is connected to which I didn't have this problem for the two weeks after building the pc. Any suggestions are welcome.

Motherboard - Asus Rog Strix z790 - e gaming (which has a 2.5 Gbps Ethernet connection) <What is the brand and model# of the 2.5Gb ethernet adapter on the motherboard? Seen others reported problems with Aqtion and Marvell chipsets.

Realtek doesn't seem to have this problem with the CAX80. Be sure drivers are up to date for this adatper as well. Try a different adapter to test.

Internet Provider and Service - Xfinity Gigabit Extra (speeds up to 1200mbps)

Ethernet Cable - CAT6a STP (25ft) <Does this happen with a shorter cable to test? 

What FW version is loaded on the CAX80?
