If you’re using Network Manager, you need to remove all Wi-Fi configuration from your /etc/network/interfaces, since NM will by default ignore all interfaces listed there. However, the same cannot be said about wpa_supplicant, since you’re explicitly enabling it here. I would not mix those two things: it’s either NM+wpa_supplicant manage the interfaces, and there are no wireless interfaces configured in /e/n/interfaces, or you don’t use NM and configure Wi-Fi strictly using /e/n/i. -- Cheers, Andrej
