Netgear DGND3700 사용자 가이드

If the error persists, you could have a hardware problem and should contact NETGEAR 
technical support.

Power LED Is Red

When the router is turned on, it performs a power-on self-test. If the Power LED turns red 
after a few seconds or at any other time during normal operation, there is a fault within the 
router. 

If the Power LED turns red to indicate a router fault, turn the power off and on to see if the 
wireless modem router recovers. If the power LED is still red 1 minute after power-up:

Turn the power off and on one more time to see if the wireless modem router recovers.

Clear the router’s configuration to factory defaults as explained in 

page 156. This sets the router’s IP address to 192.168.0.1. 

If the error persists, you could have a hardware problem and should contact NETGEAR 
technical support.

LAN LED Is Off

If the LAN LED does not light when the Ethernet connection is made, check the following:

The Ethernet cable connections are secure at the wireless modem router and at the hub 

or workstation.

The power is turned on to the connected hub or workstation.

Wireless LEDs Are Off

If the 2.4 GHz and 5 GHz Wireless LEDs do not light, the radios might be turned off. Press 
the Wireless On/Off button on the front panel

 to turn the radios back on.

DSL or Internet LED Is Off

If the DSL or Internet LED does not light, check to make sure that you are using the correct 
cable. When connecting the ADSL or Ethernet WAN port, use the cables that were supplied 
with the wireless modem router. If the DSL or Internet LED is still off, this could mean that 
there is no ADSL or fiber/cable modem service or the cable connected to the ADSL or 
Ethernet WAN port is bad.
