My question it's...... it's the wireless connection need for some devices ? Like some joystick or joypad used wireless instead bluethoot?
Not that I am aware of any, but all my controllers are wire based (I am not a Fan of wireless HIDs) - but as long as you are not owing such a device, why not disabling the wifi, as it could always be reenabled again ? ;)
For the moment i have thinks it's best idea to maintain active :)
Some time i goes in trasfert to my houses of friends or my brother house and pass whit us some hours on retropie in double :)
In most of cases in this houses i can't connect my Pi4 to a LAN Network if for example we need to add some roms to my collection or something like that and if i disable the wi-fi now how i can re-enable it whiout the possibility to re-edit the config.txt ?
Problably i can do it using a keyboard attach to a usb port......press F4 and do it from console using "nano" but i'm not sure.
Could it be a suggestion ..... why not add a function to activate or deactivate the adapter directly from the retropie-setup?
