Configure Wireless Networking

You can configure wireless networking in Photon OS. Connect to an open network or a WPA2 protected network using wpa_cli and configure systemd-networkd to assign an IP address to the network.

• Connect using wpa_cli
• Assign IP address to network

Connect Using wpa_cli

When you connect using wpa_cli, you can scan for available networks and associate the network with a network ID.

Perform the following steps:

1. Ensure that the wpa_supplicant service is running on the WLAN interface:

   systemctl status wpa_supplicant@<wlan-interface>.service

2. Connect to wpa_cli:

   wpa_cli -i wlan0

3. Scan for available networks:

   scan

4. To see the list of networks, use the following command:

   scan_results

5. Add the network:

   add_network

   This command returns a network ID.

6. Associate the network with the network ID.

   set_network <network ID> ssid “<ssid-name>”

7. For a WPA2 network, set the passphrase:

   set_network <network ID> psk “<passphrase>”

8. Enable the network:

   enable_network <network ID>

9. Save the configuration file:

   save_config

   To exit the wpa_cli, type ‘quit`.

Assign IP Address To Network

Configure systemd-networkd to assign IP address to network. Perform the following steps:

1. Create a /etc/systemd/network/98-dhcp-wlan.network file with the following contents:

   [Match]
   Name=wlan*
   [Network]
   DHCP=yes
   IPv6AcceptRA=no
   

2. Restart systemd-networkd using:

   systemctl restart systemd-networkd
