1. Introduction
1.1 What is LG308
The LG308 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 LG308 uses Semtech packet forwarder and fully compatible with LoRaWAN protocol. It
includes a SX1301 LoRa concentrator, which provides 10 programmable parallel demodulation
paths.
LG308 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.
LG308 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 LG308
The LG308 is configured as a WiFi Access Point by default. User can access and configure the
LG308 after connecting to its WiFi network, or via its Ethernet port.
2.1 Find IP address of DLOS8
2.1.1 Connect via WiFi
At the first boot of LG308, it will auto generate an unsecure
WiFi network call dragino-xxxxxx
Note: In latest version firmware, it has been password
protected and the password is:
dragino+dragino
User can use the laptop to connect to this WiFi network. The
laptop will get an IP address 10.130.1.xxx and the LG308 has
the default IP 10.130.1.1
2.1.2 Connect via WAN port with DHCP IP from router
Alternatively, connect the LG308 WAN port to your router and LG308 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 LG308. You can also use this IP to connect.

2.1.3 Connect via LAN port with direct connection from PC
The LG308 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 via WiFi with DHCP IP from router
If the LG308 already connect to the router via WiFi, use can use the WiFi IP to connect to LG308.
2.1.5 Connect via LAN port by fall back ip
The LAN port also has a fall back ip address for access if user doesn’t connect to uplink router.
