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...

What is the brand and model# of this 5G adapter in your PC that your connecting to the port?. 

Be sure the drivers for this adapter is up to date.

Does a 1000Mbps network adapter do the same thing? You might try a 2.5Gbps adapter instead...

    Like FURRYe38 says, check the card in the computer. 

    I had a qnap 2.5/5/10g card that has been nothing but problems in my server/media pc. 

    I could pull full speeds but my streaming would freeze/drop consitently. Opened a support case with qnap and had a few beta drivers we tried and it kept happening. I finally switched to a tplink 10g card and its been rock solid since. 

     

    Every once in a while I pull the old card out and update drivers and test it and its still been sketchy.

        Do you have any other 2.5/5/10g devices?

        Its tough to tell which one is causing the issue when you've only got 2 devices. 

        I ran into the issue when I had mine because I only had 2 devices as well. I did a little research with mine and see quite a few issues with the card so tried a new add in card. 

        I can't tell you what to do though. 

        If you don't have another 2.5/5/10g device, know anyone's you could borrow to test?

    Hello, thank you for the reply! 

    it is a Marvell AQtion AQC111C 5Gb Ethernet

    Yes, the drivers are fully up to date. I've attached the screenshot below. 
    So what I've figured out after hours of testing - the ONLY time the ethernet drops is when Muli-Gigabit port is being used AND in multi-gig mode. The multi-gig port works fine in 1gbps mode! With that being said, I don't know what to do.

    Also for reference - my 5Gb port is on my ASUS ROG Maximus XII Hero

    Any suggestions would be much appreciated!
