Yes, indeed there are the keys (Fn + F5) that indicate the activation of Wi-Fi, but if I press them... nothing happens, even after activating the switch that also turns on Bluetooth.
Hello and thank you for everything, but I think I will look for another computer. I got this LENOVO from my brother who lives in France. I don't know if the network card is missing or not!!! Sorry for interrupting our conversation as well; my connection was interrupted due to lack of credit.
