I was trying to connect to wifi from my RPI3 running Ubuntu 22 server.

This is my conf file

/etc/wpa_supplicant/wpa_supplicant.conf

Ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=NL

network={
scan_ssid=1
ssid="JioFiber-Uc9FK"
psk="HPASSWORDp"
key_mgmt=WPA-PSK
}

Here is the truncated output of network scan.

sudo iwlist wlan0 scan

Output

Here is the output of ifconfig

hpoddar@raspberrypi:~$ ifconfig

I did restart wpa_supplicant but I am still not connected to the wifi.

sudo systemctl restart wpa_supplicant
