Manual Setup

Use the topics and procedures below to manually set up your modem router.

Understanding ADSL Microfilters

ADSL technology uses the same wires as your telephone service. However, ADSL adds signals to
the telephone lines which create noise in the telephone service. You must use ADSL microfilters to
filter out these signals before they reach your telephone.
If you purchased the modem router in a country where a microfilter is not included, you
must acquire one.

Each device such as a telephone, fax machine, answering machine, or caller ID display will require
an ADSL microfilter.
Do not connect the modem router to the ADSL line through a microfilter unless the
microfilter is a combination microfilter/splitter specifically designed for this purpose.
Doing so will prevent block your connection to the Internet. If you have any doubts
about this, connect the modem router directly to the ADSL line.
