User Manual

Models with a USB port support the connection of a compatible USB Ethernet adapter (sold separately). If there are not enough free network ports, you can add an additional LAN port in this way.

To support USB Ethernet adapters, two components must be installed in the router:

1. CDC Ethernet interface for 5G/4G/3G USB modems (mandatory, parent component)

2. USB Ethernet adapters (dependent component)

Once you have installed the necessary components, connect the adapter to a USB port on your router.

The router will automatically detect the connected device and, depending on the model and chipset used, add information about the interface to the configuration (in the startup-config.txt file). For example:

interface RealtekEthernet0
    description "Realtek USB Ethernet"
    usb device-id 0bda 1a56
    security-level public
    ip address dhcp
    ip dhcp client dns-routes
    ip dhcp client name-servers
    up

interface CdcEthernet0
    description "RTL USB-LAN"
    usb device-id 1a86 e396
    ip address dhcp
    ip dhcp client dns-routes
    ip dhcp client name-servers
    up

interface AsixEthernet0
    description "USB_Ethernet"
    usb device-id 0b95 1790
    security-level public
    ip address dhcp
    ip dhcp client dns-routes
    ip dhcp client name-servers
    up

You can display the current router configuration in the command-line interface (CLI) using the show ru command.

To display a list of all interfaces, enter the show interface command, then press the Space and Tab keys on your keyboard in sequence.

Once you have verified that the interface has been created, you need to combine it with the LAN network ports into a single segment (by default, this is Bridge0). To do this, execute the respective commands. For example:

interface Bridge0 include RealtekEthernet0
system configuration save

interface Bridge0 include CdcEthernet0
system configuration save

interface Bridge0 include AsixEthernet0
system configuration save

Now connect the network device to the USB Ethernet adapter with a patch cord. Ensure that the device has automatically obtained an IP address from the router and has Internet access.
