How to connect to WiFi network with WPA2 PSK?

Establish connection

wpa_passphrase "SSID" > /etc/wpa_supplicant.conf

-> In the next step, please enter the password

rfkill unblock all

ip link set wlansom0 up

wpa_supplicant -B -i wlansom0 -c /etc/wpa_supplicant.conf

udhcpc -i wlansom0

Disconnect

ip link set wlansom0 down
