Position Your Wireless Router

The wireless 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

router. For example, the thickness and number of walls the wireless signal passes through

can limit the range. For best results, place your 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 wireless 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, PCs, or the base of a cordless phone or 2.4

GHz cordless phone.

•

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.

Note:

The DGND3700 should be put in a vertical position only.

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, use 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 N600 Wireless Modem Router

on page 20.

An ADSL microfilter is a small in-line device that filters ADSL interference out of standard

phone equipment that shares the same 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, answering

machines, and caller ID displays. Note that not every phone line in your home necessarily

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 equipment 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 connection. 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.

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 equipment. Plug the

ADSL microfilter into the wall outlet, plug your phone equipment into the jack labeled Phone,

and plug the wireless modem router into the jack labeled ADSL.

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.

•

Two-line ADSL microfilter with built-in splitter (included). Use to share an outlet with a

phone and the wireless modem router.
