3. Product Functions
This chapter introduces the functions of USR-G806, as the following diagram shown, you can get an overall
knowledge of it.
Figure 7 Product function
3.1. Configuration Process
（1）Connect the 4G antenna and Wi-Fi antenna to the router. (Longer one is 3G/4G antenna and Shorter
one is Wi-Fi antenna.)
（2）Plug the SIM card in G806.
（3）Power on the module by power adaptor and check the LED status.
（4）Connect PC or mobile to the G806 router via LAN interface or Wi-Fi interface. Wi-Fi password is
“www.usr.cn”.

（5）Log in Web Server of router. (Default IP address of router is 192.168.1.1, either the username and
password is “root”.)
（6）Configure APN parameters according to SIM card. Some SIM card APN can be recognized
automatically.(Network->APNSET)
（7）Configure other parameters according to user applications.
3.2. Interconnection
3.2.1 WAN+4G
Figure 8 WAN+4G
This networking mode has two WAN ports (WAN ports of Ethernet port and 4G ports of M2M network) that can
be connected to WAN simultaneously. The two channels form complementary and backup. At the same time, WAN
ports of Ethernet port are preferred to ensure data fluency and save the traffic of 4G. When WAN ports are
abnormal, they can’t be connected to WAN. The router can also connect to the server through the 4G network port.
In this way, the router doesn’t need any settings to connect to the network line, plug in 4G SIM card, and supply
power to the router. The process of setting up customers is reduced to the greatest extent. Under this networking
mode, the WIFI function of router can also work at the same time to maximize the number of LAN access.
This method is mainly used in the stably network, Such as factory buildings, intelligent buildings, smart cities and
other related industries.
