I have a Raspberry Pi 3 with built-in wifi card. When I do run
ifconfig I can find the wlan0 device. Before I never had a wifi problem until I connected the Raspberry Pi to my TV through the HDMI port.
On my laptop, I can see that the access point is detected and working fine. The Raspberry Pi however is showing: No wireless interfaces found.
What happened to the wifi of my Raspberry pi?
UPDATE 1: Find below my wpa_supplicant.conf file
sudo leafpad /etc/wpa_supplicant/wpa_supplicant.conf file
