    Slow Ethernet – ROG HERO XI and Windows 10 Pro (No GameFirst)


    I have a new build using a ROG HERO XI, 9900K and Windows 10 Pro.

    I’m having some challenges getting a consistent download speed on the built in Intel Ethernet i219-V. My internet provider download speed is rated at 300Mbps, and I’m getting anywhere from 90-160Mbps or so on a wired connection (CAT 6).

    Other PCs on the same network get 300+Mbps on a wired connection. I have also swapped my CAT 6 cable to one that I know to be working.
    From reading previous posts, the first suggestion seems to be to uninstall GameFirst. I’ve actually never installed that utility, and I can’t seem to find it in my program files. But I have installed AI Suite 3.

    Could I have misconfigured something in my bios?

    Any suggestions would be appreciated.
