3. QUICK START
4G router provides a wireless remote fast networking solution for user devices, and parameters
are set through the built-in web page to meet the application scenario.This chapter is a quick
introduction to WS-431E router products. It is recommended that users read this chapter and
follow the instructions to have a basic understanding of 4G router products. Refer to subsequent
sections for specific functional details and descriptions.

3.1.1. HARDWARE ENVIRONMENT
Product test data flow topology:
Figure 4 Get started testing data flow diagrams
Hardware: 1 PC, 1 set of router (including antenna, power adapter), 1 network cable
(self-provided), 4G SIM card (self-provided)
Wiring: The computer is connected to the LAN port of the WS-431E through the network
cable, and the WiFi antenna and the full-frequency antenna are connected to the
corresponding antenna interface in turn
Networking: Insert the SIM card in the power off state (the front of the card slot
corresponds to the positive direction of the "sim "screen printing)
Power supply: The working voltage of the WS-431E is DC5-36V. You are advised to use the
DC 12V/1A power adapter provided by the factory
After power-on, observe the indicators: the PWR is on, the LAN is blinking, the 4G indicator
(3G+2G) is on, and the indicator is all on, indicating that the signal is good

Figure 5 4G indicator (3G+2G)
3.1.2. NETWORK CONNECTION
Internet test: Power on the WS-431E, wait for about 2 minutes, the 2/3G indicator starts to light,
indicating that the 4G network of the router is successful, then you can directly surf the Internet.
Let's go to the Settings to check the network status through the default parameters of WS-431E.
Default parameters of WS-431E as follows:
SSID
WS-431E-XXXX
IP Address
192.168.1.1
User name
admin
Password
admin
WLAN Password
www.waveshare.com
Take default parameters as example: User can connect PC to SSID WS-431E-XXXX. Then open
browser and enter 192.168.1.1, log in with User name and Password(both are admin), user can
enter WebServer.

4.2. APN
4.2.1. APN CONFIGURATION BY WEB SERVER
WS-431E 4G Router
www.waveshare.com 13 /68 www.waveshare.com/wiki
In this networking mode, user can access internet through WAN interface and 4G interface. WAN
interface has higher priority than 4G interface to ensure communication and save 4G flows.
When WAN interface occurs problems, router can change to 4G interface to connect internet. In
this mode, user can also connect to router through WIFI.
To achieve this mode, user don’t need to change the router’s parameters. Just connect the cable
to router and insert SIM card, then power the router.
Application diagram as follow:
Figure 11 WAN+LAN+4G networking
4.3.2. LAN+LAN+4G
In this networking mode, three devices can connect to router through LAN and access the
Internet by 4G network. User can achieve this by Web Server as follow:
