Position Your Wireless Router
The wireless modem router lets you access your network from anywhere wit\
hin the operating 
range of your wireless network. However, the operating distance or range of your wireless 
connection can vary significantly depending on the physical placement of\
 your router. For 
example, the thickness and number of walls the wireless signal passes th\
rough can limit the 
range. For best results, place your router: 
• Near the center of the area where your computers and other devices opera\
te, and 
preferably within line of sight to your wireless devices.
• So it is accessible to an 
 AC power outlet and near Ethernet cables for wired computers.
• In an elevated location such as a high shelf, keeping the number of wall\
s and ceilings 
between the wireless modem router and your other devices to a minimum.
• A
way from electrical devices that are potential sources of interference, \
such as ceiling 
fans, home security systems, microwaves, computers, or the base of a cor\
dless phone or 
2.4 GHz cordless phone.
• A
way from any large metal surfaces, such as a solid metal door or aluminu\
m studs. Large 
expanses of other materials such as glass, insulated walls, fish tanks, \
mirrors, brick, and 
concrete can also affect your wireless signal.
Note: The DGND4000 should be put in a vertical position only. 
						

							Hardware Setup 18
N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000 
Also be aware that when you use multiple access points, it is better if \
adjacent access points 
use different radio frequency channels to reduce interference. The recommended channel 
spacing between adjacent access points is five channels (for example, u\
se Channels 1 and 
6, or 6 and 11).
ADSL Microfilters
If this is the first time you have cabled a wireless router between an ADSL phone line and 
your computer or laptop, you might not be familiar with ADSL microfilters. If you are, you can 
skip this section and proceed to Cable Your N750 Wireless Modem Router  on page
  19.
An ADSL microfilter is a small inline device that filters ADSL interference out of standard  phone equipment that shares line with your 
 ADSL service. Every telephone device that 
connects to a telephone line that provides ADSL service needs an ADSL microfilter to filter 
out the ADSL interference. Example devices are telephones, fax machines, answeri\
ng 
machines, and caller ID displays. Not every phone line in your home nece\
ssarily carries 
ADSL service. That depends on the ADSL service setup in your home.
Note: Often the ADSL microfilter is included in the box with the wireless 
modem router. If you purchased the wireless modem router in a 
country where a microfilter is not included, you have to acquire the 
ADSL microfilter separately.
One-Line ADSL Microfilter (Not Included)
Plug the ADSL microfilter into the wall outlet and plug your phone equip\
ment into the jack 
labeled Phone. The wireless modem router plugs directly into a separate ADSL line. Plugging 
the wireless modem router into the phone jack blocks the Internet connec\
tion. If you do not 
have a separate ADSL line for the router, the best thing to do is to use an ADSL microfilter 
with a built-in splitter.
Plugs into ADSL line
Figure 5. One-line ADSL microfilter
Second best when you do not have a separate ADSL line for the router is to get a separate 
splitter. To use a one-line filter with a separate splitter, insert the splitter into the phone outlet, 
connect the one-line filter to the splitter, and connect the phone to the filter.  
						

							Hardware Setup 19
 N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000
Two-Line ADSL Microfilter (Included)
Use an ADSL microfilter with a built-in splitter when there is a single \
wall outlet that provides 
connectivity for both the wireless modem router and your telephone equip\
ment. Plug the 
ADSL microfilter into the wall outlet, plug your phone equipment into th\
e jack labeled Phone,  and plug the wireless modem router into the jack labeled ADSL.
Plugs into the ADSL line

Summary
• One-line ADSL microfilter (not included). Use with a phone or fax machine.
• Splitter (not included). Use with a one-line 
 ADSL microfilter to share an outlet with a 
phone and the wireless modem router.
• T
wo-line ADSL microfilter with built-in splitter (included). Use to share an ou\
tlet with a 
phone and the wireless modem router.
Cable Your N750 Wireless Modem Router
WARNING:
DO not stack equipment, or place equipment in tight spaces, or in 
drawers. Be sure that your equipment is surrounded by at least 
2
  inches of air space. The unit should not be wall mounted.
