This guide demonstrates how to configure WiFi using systemd-networkd. It is important to use the correct network interface for the module assembled on your DART-MX95.
Managing WiFi using systemd-networkd
systemd-networkd is a system daemon that manages network configurations. It detects and configures network devices as they appear. systemd-networkd's functionality can be useful for both wireless and wired networks. This guide describes how to use systemd-networkd to configure wireless networks.
Enabling and disabling WiFi
To enable WiFi run
# networkctl up wlan0
To disable WiFi run
# networkctl down wlan0
Configuring WiFi Client
Scanning for available WiFi APs
If WiFi is enabled you can get the list of available APs by running
# iw dev wlan0 scan | grep SSID
Connecting to a protected WiFi network
Create /etc/systemd/network/80-wifi-station.network
# cp /lib/systemd/network/80-wifi-station.network.example /etc/systemd/network/80-wifi-station.network # echo "" >> /etc/systemd/network/80-wifi-station.network # echo "[DHCPv4]" >> /etc/systemd/network/80-wifi-station.network # echo "RouteMetric=9" >> /etc/systemd/network/80-wifi-station.network # echo "[IPv6AcceptRA]" >> /etc/systemd/network/80-wifi-station.network # echo "RouteMetric=9" >> /etc/systemd/network/80-wifi-station.network
Create /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
# mkdir -p /etc/wpa_supplicant # echo "ctrl_interface=/var/run/wpa_supplicant" > /etc/wpa_supplicant/wpa_supplicant-wlan0.conf # echo "eapol_version=1" >> /etc/wpa_supplicant/wpa_supplicant-wlan0.conf # echo "ap_scan=1" >> /etc/wpa_supplicant/wpa_supplicant-wlan0.conf # echo "fast_reauth=1" >> /etc/wpa_supplicant/wpa_supplicant-wlan0.conf # wpa_passphrase <SSID> <password> >> /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
Restart the services
# systemctl restart systemd-networkd.service
# systemctl restart wpa_supplicant@{ifname}.service
Wait a few seconds and than make sure wlan0 is up and connected to the AP
# ifconfig wlan0
