Mobile Network Configuration

#Routers #Mobile

Mobile network parameters are configured in the /mobile/modem section.

modem1…N — Cellular module; the number of modules depends on the router model.
sim1…N — SIM card located in the corresponding SIM slot.

The mobile network functions with default settings once the SIM cards are installed.

Current connection status is displayed on the device’s dashboard.

Basic Parameters

Disabled — Disables the modem.
Default Route — Uses the cellular connection as the default route.
Metric — A numerical value determining route priority (lower values are preferred). A metric must be specified for the Default Route to function. To prevent routing conflicts, the metric value must be unique for each interface.
Specific Bands — Selection of frequency bands. If the cellular module supports band selection, the Specific Bands field and the list of available bands are displayed in the web interface. The following notation is used: b<x> — 4G, wcdma<x> — 3G, gsm<x> — 2G (not supported by all modules).

CLI Configuration

Execution of the [TAB] command displays the default parameter values.
