N300 Wireless ADSL2+ Modem Router DGN2200v4
Position Your Modem Router
The modem router lets you access your network from virtually anywhere within 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 modem router.
For example, the thickness and number of walls the wireless signal passes through can limit
the range. For best results, place your modem router:
•
Near the center of the area where your computers and other devices operate 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 walls and ceilings
between the modem router and your other devices to a minimum.
•
Away from electrical devices that are potential sources of interference, such as ceiling
fans, home security systems, microwaves, computers, or a 2.4 GHz cordless phone and
its base.
•
Away from any large metal surfaces, such as a solid metal door or aluminum studs. Large
expanses of other materials such as glass, insulated walls, fish tanks, mirrors, brick, and
concrete can also affect your wireless signal.
ADSL Microfilters
If this is the first time you have cabled a modem router between a DSL phone line and your
computer or laptop, you might not be familiar with ADSL microfilters. If you are, you can skip

An ADSL microfilter is a small inline device that filters DSL interference out of standard phone
equipment that shares the same line with your DSL service. Every telephone device that
connects to a telephone line that provides DSL service needs an ADSL microfilter to filter out
the DSL interference. Examples of devices are telephones, fax machines, answering
machines, and caller ID displays. Not every phone line in your home necessarily carries DSL
service. That depends on the DSL service setup in your home.
Note:
Often the ADSL microfilter is in the box with the modem router. If you
purchased the modem router in a country where a microfilter is not
included, you have to acquire the ADSL microfilter separately.
One-Line ADSL Microfilter
Plug the ADSL microfilter into the wall outlet and plug your phone equipment into the jack
labeled Phone. The modem router plugs directly into a separate DSL line. Plugging the
modem router into the phone jack blocks the Internet connection. If you do not have a
