    10G NICs slow in Windows 11


    I can only get them to run at 2 Gbits/sec per iperf3 in Windows 11 Pro 23H2 64-bit using a 50 foot Cat 8 patch cable to connect the computers directly ASUS Prime Z370-P motherboard; Intel Core i7-8700K processor. They are Intel X550-T2 and Asus XG-C100C, running latest drivers and firmware. Under Settings>Network & internet>Ethernet> shows Link speed Receive/Transmit: 10/10 Gbps, but under Settings>Network & internet>Advanced network settings> shows Link speed: 1410 Mbps [same result with Windows in Safe Mode with networking].

    How to make 10G eth primary?

    Using a 10g nic card on a 1g network wont give you 10g. Everything between your computer and the router needs to support 10g. The nic card, the cable and the modem itself.

    There's no connection between those two. They run on different controllers, chips and circuits.

    10G NICs slow in Windows 11

    Latest Samsung NVMe Driver Released

    1 PC has 10G NIC on motherboard. 3 PCs have 10G PCIe NICs installed (Aquantia, ASUS XG-C100C, Rosewill). 2 PCs have 2.55g NIC on motherboard.

    My PC has the 10G NIC onboard (MSI X299 Creator). The test PC Uses the Aquantia PCIe card (MSI X299 XPower Gaming AC). In both cases I uninstalled the drivers, and on Mine I also disabled the NIC in the BIOS.

    TEST PC: Run tests with 10G NIC installed and operational, Run tests with 10G NIC no Drivers installed: Run tests with 10G NIC disabled in BIOS; Run tests with 10G NIC removed. All Same results.

    MY PC: Same as above except last step - can't remove the NIC from the motherboard 10G NICs slow in Windows 11 :)

    Is there some known issue with 10G LAN adapters causing problems with SSDs?
