WisDM Network Interface Management

To ensure a stable and continuous Internet connection, WisDM gateways support multiple network interfaces through a feature called Multi-WAN. This feature allows the gateway to maintain an online presence automatically switching between available connections based on defined priorities.

Each WisDM-compatible gateway can support up to three types of Internet connections, which can be configured simultaneously:

• Ethernet: A connection provided via an Ethernet cable (default port type: WAN).
• Wi-Fi: A connection established through a wireless Wi-Fi network.
• Cellular: A connection provided via a SIM card using the cellular network (available on models equipped with a cellular module).

How Multi-WAN Works

1. Automatic failover: Multi-WAN monitors all enabled interfaces and switches to the next available one if the primary connection becomes unavailable.
2. Priority-based switching: The order of interfaces is user-defined, allowing control over which connection is preferred.
3. High availability: The gateway remains online as long as at least one interface is active. It only goes offline when all enabled interfaces lose connectivity.

NOTE

• Network interfaces are configured per gateway. However, to streamline the process and apply settings in bulk, you can use the Synchronize Network Interface Settings feature.
• Network interface status information is synchronized from the gateway at approximately 10-minute intervals.

WAN Interface Priority

WAN interface priority defines the order in which the gateway uses available WAN interfaces for internet connectivity.

The gateway tries to use the Primary interface first. If the Primary interface becomes unavailable, the gateway can switch to the Secondary interface. If the Secondary interface is also unavailable, the gateway can switch to the Tertiary interface.

Priority Label	Description
Primary	The first WAN interface the gateway tries to use.
Secondary	The backup WAN interface used when the Primary interface is unavailable.
Tertiary	The fallback WAN interface used when both Primary and Secondary interfaces are unavailable.

1. Navigate to Gateways > Select a gateway > Network interface > WAN, then click Edit.

Figure 1: Network interfaces

2. Use the arrows ( ) to adjust priority.

Figure 1: Configure network priorities

• Up arrow: Increases priority.

• Down arrow: Decreases priority.

3. Click Save priorities to apply the changes. The new configuration will be sent to the gateway.

Figure 1: Apply updates

NOTE

If priority updates are not applied within 3 minutes, you can either Delete pending changes (which will keep the gateway's existing configuration) or Resend them.

WAN Interfaces

The WAN interfaces (Ethernet, Wi-Fi, and Cellular) provide visibility and control over the gateway’s network connectivity.

You can:

• Monitor the connection status of each interface
• View signal strength and quality metrics for Wi-Fi and Cellular connections
• Configure network parameters based on your deployment requirements

NOTE

The availability of WAN interfaces depends on the hardware capabilities of the gateway. Not all interfaces are supported on every device, and only the available interfaces will be displayed in the system.

WAN Status Indicators

On the WAN page, WisDM displays status indicators and labels to show the current state of each WAN interface.

Indicator	Description
Green status indicator	The WAN interface is enabled and currently available for WAN connection.
Red status indicator	The WAN interface is not currently available for WAN connection. This may happen when the interface is disabled, disconnected, has no SIM card, fails to connect, or fails the connectivity check.
ACTIVE	Indicates the WAN interface currently used by the gateway for internet connectivity. Only one WAN interface can be active at a time.
NO SIM CARD	Indicates that no SIM card is detected or the SIM card is unavailable.
Wi-Fi signal strength	Indicates the Wi-Fi signal condition. More signal arcs generally mean a stronger Wi-Fi signal.
Wi-Fi unavailable	Indicates that the Wi-Fi interface is not currently connected or no valid Wi-Fi signal information is available. This may happen when Wi-Fi is disabled, disconnected, or fails to connect.
Cellular signal strength	Indicates the cellular signal condition. More signal bars generally mean a stronger cellular signal.
Cellular unavailable	Indicates that the Cellular interface is not currently connected or no valid cellular signal information is available. This may happen when Cellular is disabled, no SIM card is detected, the SIM card is unavailable, or the cellular connection fails.

LAN Interfaces

In addition to its connection to the internet (WAN group of settings), the gateway can share a connection with nearby devices.

LAN Status Indicators

On the LAN page, WisDM displays status indicators to show the current state of LAN interfaces.

LAN interfaces are used to provide local network access to nearby devices.

Indicator	Description
Green status indicator	The LAN interface is enabled and available for local device access.
Red status indicator	The LAN interface is not currently available for local device access. This may happen when the interface is disabled or when the interface has an issue.

Ethernet

The same Ethernet port can be configured for either WAN or LAN. In WAN mode, the gateway acts as a client to connect to the internet. In LAN mode, it acts as a server, providing network access to connected devices. The port cannot function as both simultaneously.

1. View interface details by clicking on the interface name or the arrow next to it.

Figure 1: Ethernet

2. Click Settings to configure the LAN ethernet interface.

Figure 1: Ethernet settings

• Enabled/Disabled: Enable or disable the LAN Ethernet interface.

  NOTE

  Enabling Ethernet LAN may result in the loss of the gateway's internet connection, which could trigger a rollback operation if no other interfaces are functioning.

Wi-Fi

Wi-Fi is another interface for providing local area network access. When LAN Wi-Fi is activated, the gateway functions as an access point, allowing nearby devices to connect.

1. View interface details by clicking on the interface name or the arrow next to it.

Figure 1: Wi-Fi

2. Click Settings to configure the LAN Wi-Fi interface.

Figure 1: Wi-Fi settings

• Channel: Configure the Wi-Fi channel. The default setting is Auto, which allows the gateway to select the optimal channel automatically.
• (E)SSID: Specify the SSID for the wireless access point (AP).
• Encryption: Choose the encryption type for the Wi-Fi AP. Options include No Encryption, WPA-PSK, WPA2-PSK, and WPA-PSK/WPA2-PSK Mixed Mode
• Hidden: Enable this option to conceal the SSID, making the AP invisible to devices searching for networks.

DHCP Server

For LAN interfaces, you can configure the DHCP server settings. By default, the gateway runs a built-in DHCP server that assigns IP addresses to connected devices, but you can adjust these settings as needed.

1. To view the DHCP server details, click on the interface name or the arrow next to it.
