Netgear D500 and D1500 사용자 설명서

If your modem router cannot access the Internet, check the DSL connection, then the WAN 
TCP/IP connection. 

If your modem router is unable to access the Internet, first determine whether the DSL link 
with the service provider is working. The DSL LED 

 indicates the state of this connection.

If the DSL link LED is green, the ADSL connection is good. You can be confident that the 
service provider connected your line correctly and that your wiring is correct.

If the DSL LED is blinking green, your modem router is attempting to make an ADSL 
connection with the service provider. The DSL LED turns green within several minutes. 

If the DSL LED does not turn green, disconnect all telephones on the line. If this solves the 
problem, reconnect the telephones one at a time, being sure to use a microfilter on each 
telephone. If the microfilters are connected correctly, you can connect all your telephones.

If disconnecting telephones does not result in a green DSL LED, a problem with your wiring 
might exist. If the telephone company tested the ADSL signal at your network interface 
device (NID), then wiring in your house might be of poor quality.

If the DSL LED 

 is off, the Internet LED 

 is off, or both are off, disconnect all telephones 

on the line. If this solves the problem, reconnect the telephones one at a time, being sure to 
use a microfilter on each telephone. If the microfilters are connected correctly, you can 
connect all your telephones.

If disconnecting telephones does not result in a green DSL LED, check the following:

Check that the telephone company made the connection to your line and tested it.

Verify that you are connected to the correct telephone line. If more than one phone line is 
installed, be sure that you are connected to the line with the ADSL service. It might be 
necessary to use a swapper if your ADSL signal is on pins 1 and 4 or the RJ-11 jack. The 
modem router uses pins 2 and 3.
