Windows 10: Unable to use 5Ghz wifi on the newest windows 10 update KB4512508

Firstly my computer is compatible.

Secondly, my computer is able to detect my 5ghz wifi before the update due to me being able to disable 802.11d

Thirdly, after the update, I have no ways to disable it thus making it literally impossible to detect my 5ghz wifi.

In the end, I have to revert the update.

Someone, please help me.

5ghz wifi not showing windows 10


I just got a new modem/router and it has a 2.4ghz and 5ghz wifi connections...Only the 2.4ghz shows in the wifi list while the 5ghz isn't showing at all. My computer's network card does support the 5ghz and I know the 5ghz is working because I can connect to it from other devices...just not my desktop computer.

EDIT: I've attempted updating network driver, also resetting network in the settings menu. Both hasn't worked.

 

After the newest windows update, my 5Ghz wifi download speed is limited.

My 5Ghz wifi download speed is limited after the newest windows update .

my download speed is about 150 mbps(by speedtest by Ookia) , but after the update, my download speed is 5mbps , and the upload speed is 20mbps, which high than my download speed..

I tried to switch to the 2.4Ghz wifi and run the test, the speed remain the same before the update.

I think there is no problem with my usb wifi adapter, because I ran speedtest on my other computer which is old windows version with the adapter, the download speed is 150mbps.

How can I fix this?
