There are total 4 types of connection method that you can use to access the Internet: CableRepeater3G/4G Modem and Tethering.

Click Internet to create an Internet connection.

1. Cable

Connect the IR300 router to the modem or main router via Ethernet cable to access the Internet.

Before plugging the Ethernet cable into the WAN port of the router, you can click Use as LAN to set the WAN port as a LAN port. That is useful when you are using the router as a repeater. As a result, you can have one more LAN port.

Plug the Ethernet cable into the WAN port of the router. The information of your connection will be shown on the Cable section. DHCP is the default protocol. You can click Modify to change the protocol.


DHCP is the default and most common protocol. It doesn’t require any manual configuration.


Static is required if your Internet Service Provider (ISP) has provided a fixed IP address for you or you want to configure the network information such as IP address, Gateway, Netmask manually.

The current settings will be automatically filled once you choose Static. Change it according to your needs and then click Apply.


PPPoE is required by many Internet Service Providers (ISP). Generally, your ISP will give you a modem and provide you a username & password that you needed when you are creating the Internet connection.

Under PPPoE protocol, enter your username and password, then click Apply.

2. Repeater

Using Repeater means connecting the router to another existing wireless network, e.g. when you are using free Wi-Fi in a hotel or cafe.

It works in WISP (Wireless Internet Service Provider) mode by default, which means that the router will create its own subnet and act as a firewall to protect you from the public network.

In Repeater section, click Scan to search for the available wireless networks nearby.

Choose a SSID from the drop-down list and enter its password. You can also enable the Remember button to save the current chose wireless network. Finally, click Join.

3. USB 3G/4G Modem

You can connect to the Internet using a USB 3G/4G modem.

Some SIM cards may need to be activated the first time you use them, so please activate them in your phone before using them in your router.

We recommend to turn off the router first, insert your SIM card into the USB modem then plug the USB modem into the USB port of the router, and then turn it on again.

The first time, when the router is powered on, it may not connect automatically, but it has read the name of your carrier in the upper left corner, and you need to click Auto Setup.

After a while, it will be connected.

Normally, the second time, when the router is powered on, after a while, it will automatically recognize the SIM card and establish a connection. It may not get the information of signal, modem name and IMEI.

If you insert a usb modem at power on, it will not automatically connect. 

If it shows the carrier name in the upper left corner, you can click Abort. After a while, the button will turn to Auto Setup, then click Auto Setup.

  • Please note that there is your carrier name in the upper left corner of it. Click Abort, wait a while, and if it doesn’t work, click Modem Reset.
  • You may get into this screen, then you need to click Auto Setup, please note that at this time, there is your carrier name in the upper left corner of it.
  • Wait a moment and it will be connected.

If it doesn’t show the carrier name, you can click Modem Reset.

  • Device: Choose /dev/cdc-wdm0 if your modem supports QMI, otherwise you need to choose /dev/ttyUSB, which may include several ttyUSB from 0 to 3. You need to choose the correct one based on the modem spec. We suggest you to try ttyUSB0first.
