5ghz not showing on my MacBookPro

I have som problems when trying to watch HD video from my drive. It starts and stops, and is not smooth at all. I was thinking that 2.4ghz could be overcrowded and wanted to change to 5ghz. I can see the 5ghz SSID on my phone, but in my Mac i can’t
I can see other 5ghz networks around me, including on in my apartment, but not the one that I want to…

any suggestions ?

Where did you found a menu for 5 GHz in the admin settings? I don’t have it.

I only can setup this here:

My WiFi also does not work as ist should after firmware upgrade to 1.07.02:
