JohnnyBoyQC im not very familiar with recalbox or linux, i did wget -help and didnt find any command to test wifi speed, im getting very slow wifi speed, like 300 kb/s, sometimes t goes up to 800 kb/s but rarely
nadenislamarre for example : wget http://batocera-linux.xorhub.com/upgrades/x86_64/stable/last/boot.tar.xz however, note that this will more test your internet connexion. you should test a transfer from the local network to test the wifi only.
