The AirLink router is equipped with one 10/100/1000 Ethernet (RJ45) port that can be enabled or disabled as needed. When the port is disabled, a connected device cannot connect via Ethernet, and ARP queries do not receive responses on the port.
When connecting the router to an internal network via Wi-Fi or Ethernet WAN, ensure that the network providing a WAN link does not use the router’s default internal subnet (192.168.1.0/24). The address conflict will prevent the WAN connection from being established.

When deploying the router, Sierra Wireless recommends that WAN AUTO DETECT be disabled, and that the Ethernet ports are manually configured for LAN or WAN.
When WAN AUTO DETECT is disabled, you can configure the port for:
When WAN AUTO DETECT is enabled for an Ethernet port, the system may internally modify the DHCP settings for that port. If you disable WAN AUTO DETECT on that same Ethernet port, you should verify the WAN configuration settings (under Networking > General > WAN) and modify them if required.
For applications where LAN-only clients are connected to an Ethernet port, it is recommended to disable WAN AUTO DETECT to ensure the fastest DHCP response times, especially when experiencing delays in LAN DHCP server responses.
You can check your Ethernet port configuration under Status/Monitoring > Dashboard.
For more detail, click on an Ethernet Port entry on the dashboard, and it will automatically take you to the Hardware Interfaces > Ethernet Interfaces > Configuration section.
You can also check your Ethernet port configuration under Hardware Interfaces > General > Configuration.
Under Hardware Interfaces > General > Configuration, you can:
You can configure the Ethernet interface for WAN mode by leaving the LAN Segment field empty.
