Warning about 5g before downloading balena cups

Before downloading the balena cups file to flash, a warning says that on my Pi Zero W 5g without an adapter doesnt work.

  1. Does that mean that I need a 5g adapter persé or
  2. If my Wifi AP also supports 2.4 G I’m good to go?



Where exactly does the warning appear?

In general, it should be no problem running over the 2.4 GHz wifi!

When defining the program one wants for download, but I know enough now for download, thank you
