MAC addresses

Digi programs one MAC address for the Wi-Fi interface during manufacturing of the SOM. This is the MAC address used for the wlan0 interface. The wireless chip supports up to three other virtual MAC addresses that you must program before use (otherwise they have default values). See Wireless virtual MAC addresses for instructions.

IP settings

Digi Embedded Yocto defines configuration macros to set some of the most commonly used network interface settings. See Customize the root filesystem. By default, wlan0 is configured to obtain a DHCP address.

Wireless mode

By default, Digi Embedded Yocto is configured with concurrent station, SoftAP, and P2P capabilities. When using concurrent mode, the interface is shared between all functionalities so overall performance is affected.

Maximum performance is achieved on the physical wlan0 when the wireless interface is not shared between multiple functionalities. Digi recommends you always use the physical wlan0 interface and only configure virtual interfaces when using concurrent modes.


NetworkManager is a daemon that simplifies the configuration and use of network interfaces. It includes a command line tool, nmcli, which you can use to interact with the NetworkManager daemon. You can also configure additional network interface settings by editing /etc/NetworkManager/system-connections/nm.<interface>.
