8.2 Hardware Installation
8.2.1 Choosing the Best Location for Wireless Operation
Many environmental factors may affect the effective wireless function of the DSL
Router. If this is the first time that you have set up a wireless network device, read the
following information:
The access point can be placed on a shelf or desktop, ideally you should be able to
see the LED indicators in the front, as you may need to view them for troubleshooting.
Designed to reach up to 100 meters indoors and up to 300 meters outdoors, the
wireless LAN lets you access your network from anywhere you want. However, the
numbers of walls, ceilings, or other objects that the wireless signals must pass
through limit signal range. Typical ranges vary depending on types of materials and
background radio frequency noise in your home or business.
8.2.2 Connecting the Router
Step1 Connect the Line interface of the Router to the MODEM interface of the
splitter through a telephone cable. Connect the phone to the PHONE
interface of the splitter through a telephone cable. Connect the incoming
line to the LINE interface of the splitter.
The splitter has three interfaces:
LINE: Connect to a wall phone jack (RJ-11 jack).
MODEM: Connect to the ADSL jack of the device.
PHONE: Connect to a telephone set.
Step2 Connect the LAN interface of the Router to the network interface card
(NIC) of the computer through an Ethernet cable (MDI/MDIX).
Step3 Plug one end of the power adapter to the wall outlet and connect the
other end to the Power interface of the device.
Connection 1
Figure 3 displays the application diagram for the connection of the router, computer,
splitter and the telephone sets, when no telephone set is placed before the splitter.

Figure 3 Connection diagram (Without connecting telephone sets before the splitter)
Connection 2
Figure 4 displays the connection when the splitter is installed close to the router.
Figure 4 Connection diagram (Connecting a telephone set before the splitter)
Note:
When connection 2 is used, the filter must be installed close to the telephone
cable. See Figure 4. Do not use the splitter to replace the filter.
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.
