I have recently purchased a gigabyte sabre 17wv8 laptop which has Intel Wireless-AC 9462, and have installed latest Windows 10 Pro OS V1803.
Wireless works fine, except when I try and use Hyperv and create an external switch using wireless. What happens is the upload speed is slowed down or throttled to 1Mb/s, download speed is fine. The slowdown is experienced on both the host and the vm's. Soon as I delete the external switch, the upload speed returns to normal. It appears that this fault is related to the version of windows/hyperv that includes the default network switch which can't be deleted.
I have updated the wireless driver to the latest version 184.108.40.206 and no difference
Has anybody else had similar experience? solution? request Intel to update driver?
Thank you for posting.
You already have the latest driver available from our end. So, you can try contacting Microsoft regarding the Hyper V behavior, since it's only happening with this feature it might be related to it and not to the wireless adapter. It might even be an expected behavior when using a virtual switch with Hyper V or a bug with the Windows® 10 version you are using. But, in either case you need to contact their support to get more assistance for this matter.

Crazy this is still an issue after 2 years. I just replaced my laptop with a Precision 7740 using the Intel Wi-Fi 6 AX200 and its still an problem. Drivers are all up to date.
I have the same on my 8265AC, but the other way round. Download throttled to <1Mbps. As soon as you remove the External Switch normal download speeds return.
