I've gotten a new router that broadcasts 2.4ghz and 5ghz bands. But my desktop could only see the 2.4ghz connection.
I read from a website that as long as my network adapter supports 802.11a or 802.11n network modes, this means that the computer that you are using has the 5 GHz network capability.
I ran the command
netsh wlan show drivers in console, and I do see that it supports 802.11n.
Does this mean that my wireless network card should support 5ghz network band?
