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, 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 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, answering machines, and caller ID displays. 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. Hardware Setup 18

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

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, answering
machines, and caller ID displays. 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.

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.
