Windows 10: MICROSOFT REALTEK USB GbE Family Controller Driver MS NETWORKING STACK?? is limited to...

I am unable to get the in-box Microsoft Windows 11 Realtek USB Gbe Family Controller Driver to operate at more than 500mbits. If I install the Realtek OEM driver then it works at just under a megabit until I do a reboot at which point it won't work faster than 500mbits. If I 'repair' the OEM driver using the OEM setup utility then it works at megabit speed again until the next reboot. See details below.Environment- Windows 11 home 23H2- HP Envy 17.3 inch Laptop PC 17-cr0000- HP Universal USB-C multiport hub co

Hello there! I am Charity, I'm an Independent Advisor and a Microsoft user like you.

I'm glad to help you today!

I understand you need help in regards with your network adapter limited only to 100 mbps.

Have you double-check if your network adapter supports Gbps speeds? And in regards with that, may I know the type of Realtek PCIe GBe Family Controller you're using?

You can check that from:

1. Open Device Manager > Expand Network adapters

2. Double-click on Realtek PCIe GBe Family Controller

3. Go to Details tab > Under property drop down, select "Inf section"

4. Provide what is stated in the Value.

I see. There's definitely something going on with your PCIe controller. Since you've already installed the drivers, may I confirm if that also include the Realtek PCIe GbE Family Controller? And did you downloaded the drivers from the motherboard's manufacturer website?

You can try to disable and re-enable the PCIe controller. Another thing to try is to reinstall the Realtek PCIe GbE Family Controller driver.
