I had this issue as well on a laptop I was setting up for a friend, I had a multi band network and neither SSID was showing up.
Tried a few things but the one that seemed to work was updating the driver in device manager and selecting the Microsoft version of the network adapter instead of the intel one. Strange but it worked
Hope this helps someone
Thanks for this thread and thanks for the post from Zack Harris.
I had the same issue and fixed it by selecting the Microsoft driver instead of the Intel one.
My network adapter are [Intel(R) Dual Band Wireless-AC 3160].
Following is my operation steps:
(1) Run Device Manager;
(2) Select Network adapters and then [Intel(R) Dual Band Wireless-AC 3160]
(3) Right click and select update driver
(4) Select [Browse my computer for drivers]
(5) Click [Let me pick from a list of available drivers on my computer]
(6) Select [[Intel(R) Dual Band Wireless-AC 3160] (Microsoft)]
(7) Click Next
