Realtek based USB Wireless AC speeds

[Flak]

Is anyone getting anywhere near AC speeds using any of the realtek based USB adapters in USB 3.x slots on Windows 10?

We are doing some testing on ac adapters and ap's in our environment. For whatever reason, every single adapter we have that is realtek based and USB 3.0 fails to get above 6MB/s when connected to a USB 3.x port. When connected to a USB 2.0 port they top out the speed of USB 2.0. The machines are all different hardware, including the USB 3.x chipset being used. We've tried every driver available that would install on Windows 10. We even did a clean install of the OS between some of the driver installs.

In short, USB 2.0 seems fine. USB 3.x is a mess. They must work with all the positive reviews, unless everyone is just using them in USB 2.0 ports. So we are just trying to figure out if we're missing something here.

some controllers usb3 controllers dont do so well, Sometimes using the manufacturer driver works, sometimes using windows generic drivers work better, this has been the case for other things such as PCI and PCIe cards as well and the featureset of the driver as well. Realtek drivers tend to like to use more CPU and arent as great but they usually do tend to work decently.

My last successful test was using the asus usb 2 channel AC adapter which also has usb3. I was able to use up to 90% of the rated speed of 2 channel AC with a significant amount of packet losses during stress test. If you are getting 50% of the rated link speed that is already decent.

It does sound like a driver problem perhaps...

Which Realtek chipset (and device vendor) is in play here?

Weird... not just Realtek...

Seems like a Windows thing with 1703...

Broadcom onboard NIC here...

For Broadcom we only found two drivers that work consistently for us for both USB and PCI-E devices in Windows 10. For the USB devices using realtek chipsets we could not find any combination of drivers (realtek and usb 3.x) that worked in our environment (across a little less than 100 machines with various USB 3.x chipsets at play). The USB devices have since been returned but were, edimax ac1750, tp-link archer t9uh, asus usb-ac68 and another I can't recall.
