N450 CG3000Dv2 How do I enable 5GHz? Photo included

[pdxkmk]

I have searched 5GHz topic but this tech newbie can't find the answer to this: how do I enable 5GHz? Genie shows 2.4 but that's it. Picture shows results of trying to find 5GHz.
I would greatly appreciate any help. Talk to me like I'm 10 y.o. THANK YOU!

N450 is a Single band product. It does NOT support 5GHz.
