2.- Hardware Installation
Step 1 Connect the ADSL port of the device and the Modem port of the splitter with a telephone cable (if
Splitter is available).
Step 2 Connect the phone to the Phone port of the splitter through a telephone cable. Connect the
incoming line to the Line port of the splitter.
The splitter has three ports:
−Line: Connect to a wall phone port (RJ-11 jack).
−Modem: Connect to the DSL port of the device.
−Phone: Connect to a telephone set.
Step 3 Connect an Eth port of the device to the network card of the PC through an Ethernet cable
(MDI/MDIX).
Note:
Use twisted-pair cables to connect the device to a Hub or switch.
Step 4 Plug one end of the power adapter to the wall outlet and the other end to the Power port of the
device.
Step 4 If Splitter is not available, then plug the RJ11 cable to the ADSL port on the outer in one end, and
to the ADSL socket on the other end.
Installing a telephone directly before the splitter may lead to failure of connection between the device and
the central office, or failure of Internet access, or slow connection speed. If you really need to add a
telephone set before the splitter, you must add a microfilter before a telephone set. Do not connect several
telephones before the splitter or connect several telephones with the microfilter.
Now you have connection to the Internet.
3.- ADVANCED WEB
Enter below URL in the WEB Explorer to access to Advanced WEB UI:
http://192.168.1.1

3.2.- LAN
You can configure the LAN IP address according to the actual application. The preset IP address is
192.168.1.1. You can use the default settings and DHCP service to manage the IP settings for the private
network. The IP address of the device is the base address used for DHCP. To use the device for DHCP on
your LAN, the IP address pool used for DHCP must be compatible with the IP address of the device. The IP
address available in the DHCP IP address pool changes automatically if you change the IP address of the
device.
You can also enable the secondary LAN IP address. The two LAN IP addresses must be in different networks.
Choose LAN and you will see picture below.
