Q8: Why Wi-Fi is not available?
A: USB 3.0 devices might generate radio frequency interference that can cause Wi-Fi and other wireless
devices operating in the 2.4GHz band to have issues communicating with your Raspberry Pi4. To avoid
interference on the 2.4GHz band using Wi-Fi, try using the 5GHz band instead. If problem still exists, please
turn off Wi-Fi and use the wired network instead.
