1. Introduction

1.1 What is the LG308N

The LG308N is an open sourceLoRaWAN Pico Gateway. It lets you bridge LoRa wireless network to an IP

network via WiFi, Ethernet, 3G or 4G cellular network. The LoRa wireless allows users to send data and reach

extremely long ranges at low data-rates.

The LG308N uses Semtech packet forwarderand fully compatible with LoRaWAN protocol. It includes a SX1302

LoRa concentrator, which provides 10 programmable parallel demodulation paths.

LG308N has pre-conﬁgured standard LoRaWAN frequency bands to use for diﬀerent countries. User can also

customized the frequency bands to use in their own LoRa network.

LG308N can communicate with ABP LoRaWAN end node without LoRaWAN server. System integrator can use it to

integrate with their existing IoT Service without set up own LoRaWAN server or use 3rd party LoRaWAN service.

2. Access and Conﬁgure LG308N

The LG308N is conﬁgured as a WiFi Access Point by default. User can access and conﬁgure the LG308N after

connecting to its WiFi network, or via its Ethernet port.

2.1 Find IP address of LG308N

2.1.1 Connect via WiFi

At the ﬁrst boot of LG308N, it will auto generate a WiFi network called dragino-xxxxxxwith password:

Note: In latest version ﬁrmware, it has been password protected and the password is:dragino

+dragino

User can use a PC to connect to this WiFi network. The PC will get an IP address 10.130.1.xxx and the LG308N has

the default IP 10.130.1.1



2.1.2 Connect via WAN port with DHCP IP from router

Alternatively, connect the LG308N WAN port to your router and LG308N will obtain an IP address from your

router. In the router's management portal, you should be able to ﬁnd what IP address the router has assigned to the

LG308N. You can also use this IP to connect.



2.1.3 Connect via LAN port with direct connection from PC

The LG308N LAN port is conﬁgured as DHCP router by default, user can connect the PC to LAN port and set

PC to DHCP mode, it will get IP from LAN port and be able to access to the device. The default IP in LAN port is

10.130.1.1

2.1.4 Connect WiFi with DHCP IP from router
