Raspberry Wifi – Static IP on Wireless LAN with WPA Supplicant

Ever wondered how to set up a static IP on your Raspberry Pi connected via Wireless LAN?

1. Check your current IP and check the current Wifi setup. By default IP is given by DHCP server in your router.

sudo ifconfig

2. Edit your network interfaces file

sudo nano /etc/network/interfaces

3. Add a script segment to setup static wlan

auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
auto wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet static
  address 192.168.1.88
  subnet 255.255.255.0
  network 192.168.1.254
broadcast 192.168.255
gateway 192.168.1.254

 

4. Edit your wpa configuration file

sudo nano /etc/wpa_supplicant.conf

Create this file looking like the following.

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

network={
        ssid=”30Elmtree” #enter your wifi router id
        psk=”0433191185″ #enter your password
        proto=RSN
        key_mgmt=WPA-PSK
        pairwise=TKIP
        auth_alg=OPEN
}

 

5. Exit and save the file: Ctrl + X


6. Restart your Raspberry PI

sudo reboot

7. Test ping from another PC:

ping 192.168.1.88
