Show supported frequencies for Wi-Fi
It's not possible to know whether the Wi-Fi chip on my card supports 5GHz frequencies.
It would be useful to know what the maximum speed supported is, and whether it supports 5GHz in addition to 2.4GHz.
This is how one can check whether an adapter supports 5GHz (or just 2.4GHz) on Windows: https://www.techadvisor.co.uk/how-to/network-wifi/how-enable-5ghz-wi-fi-on-your-laptop-3608743/ and on macOS: https://networking.grok.lsu.edu/Article.aspx?articleid=17340
