Guys, I don't know why my laptop ASUS X542UF won't show 5Ghz wifi. My wireless adapter is Qualcomm Atheros QCA9377. I have the latest driver. When I go to device manager, I click on the properties>advanced, there are only 3 property that is D0 Packet Coalescing, Network Address, Roaming aggresiveness. None of those can enable 5Ghx wifi mode. I just reinstall windows 10 and it did not help. What should I do?
