My wifi Adapter only reconize 5Ghz wifi?

[Matthew Wang]

I recently got a desktop and I am using TP-link AC450, that little wifi adapter for internet connection. I noticed that it only recive my and my neighbor's 5Ghz wifi, didn't recive any 2.4Ghz, I start thinking , wait a minute, what if I go to a place with no 5Ghz wifi, then I get no wifi at all.....

 

Does this little thing only recive 5Ghz wifi or I can play around with some setting to bring 2.4Ghz out?

Here I am testing this on my laptop, as you can see for wifi connection 1(无线网络连接)which is the onboard wifi for my laptop shows 2Ghz wifi does exist, but the connection 2(无线网络连接2）which is this adapter only recive 5Ghz.

Because it is 5Ghz only, it says it on their website.
