Windows 10 Hyper-V and AC-9560 160MHz very slow


I'm seeing the exact same thing (as in https://forums.intel.com/s/question/0D50P00004dgLM3/windows-10-hyperv-and-intel-wireless-ac-9560-160mhz-very-slow) on a Lenovo T490s (20NX) running Windows 10 Enterprise 1909 latest patches and the latest drivers from Lenovo (the problem is also there in and latest drivers from Intel. It's unlikely a Windows problem since most of the similar problems are caused by drivers. It works fine with a ThinkPad USB 3.0 Ethernet Adapter and fine on a older Lenovo using AC 8265. Since this is a company laptop I'm have filed a support request with Microsoft Premier support and they are currently investigating this problem.
