Windows 10: My PC can't find 5ghz signals and i've tried other solutions

So i searched this up and the internet tells me to go to device manager and then click wireless network and see it's advanced properties and find the 810.11n or some code like that. the problem my advanced settings has nothing like this code, it just has these stuff like adapativitypara etc..and Ive clicked on updating my driver and stuff but it says its already updated. so how can i connect to 5ghz?

:)
