Firmware V2.02.05 appears to fix the issue. I've had link aggregation set up for about 16 hours now and no issues. Previously the speed would have reduced after 2-3 hours.

    I've been stable for 5 days now. Have been running speed tests every evening. Still pulling 1200down 42up. I am considering this issue finally resolved. Crazy it took a year but grateful nonetheless.

      So how does one get this firmware? I called into Spectrum and they said they have no updates for personally owned devices.

        Unfortunately it's entirely up to the ISP. I have Comcast/Xfinity and they just pushed the firmware the morning of 8/19/2020.

    Happy to report that I've had Link Agg enabled for 5 straight days and no slow downs or other issues. Now just wish Intel could fix the AX200 drivers then all would be well in my network

      FYI:  Netgear is now reporting CM1200 V2.02.05 firmware as “deployed” for Comcast – but, not for Spectrum, Cox, or other ISPs (see here).

      You'll have to post about any Intel problems over in there forums and let them know.
