I received my wireless adapter yesterday and am having this same issue. I only have a single PCIE 1x 3.0 slot available on my micro ATX motherboard, as the other slot is covered by GPU (the covered slot is also PCIE_1x/3.0).
GIGABYTE GA-B250M-DS3H
Intel Core i5-7500 3.4 GHz
GTX 1070
16GB 2400mhz DDR4
I have read through other solutions on this thread, seems like there is no fix for my use-case. Can anyone weigh in?
EDIT: After rebooting a couple of times this issue seems to have gone away.
