My WiFi 5g setting has disappeared from available settings

[wireless]

I switched from 2.4g to 5g some time ago, but now my computer is back on 2..4G and the 5g option is not listed as an availlable setting. How do I get back on 5g? Is there something I can do from my end, or do I need to call tech support?
