@Kevin_Z thanks for the reply. I was unable to install this driver. Windows 10 complains that the hash for the file is missing. Disabling mandatory driver signing via bcdedit doesn't change anything.

Same for me, please. 2.4 GHz connection works fine, but 5 GHz flaps often, and even when it doesn't, ping time is 3× higher. I hope there's an updated driver available.
