🖥️ Raspberry Pi Notes

Configure wifi using raspi-config:

Check for available SSIDs:

sudo iwlist scan | grep ESSID

ESSID:"hailtheking"

ESSID:"WLAN-151515"
ESSID:"Rittersport"
ESSID:""
ESSID:"EasyBox-476850"
ESSID:"FRITZ!Box 7560 IK"
ESSID:"FRITZ!Box 7530 VY"
ESSID:"Zahl dein Internet selber"
ESSID:"WLAN-QK2V3U"
ESSID:"WLAN-650448"
ESSID:"FRITZ!Box 7430 YE"

Copy network information:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=DE

network={
        ssid="XXX"
        psk="XXX"
}

More information on wpa_supplicant can be found here and here and here.

sudo systemctl enable wpa_supplicant.service

sudo reboot

Check if wifi is working:

ifconfig
