Wi-Fi configuration

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 Wi-Fi 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.

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

By default, Digi Embedded Yocto configures the Wi-Fi interface in client infrastructure mode (also known as station), but it is also preconfigured to enable concurrent mode. When using concurrent mode, the interface is shared between all functionalities so overall performance is affected.

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>.
