Basic Functioning
After you turn on power to the modem router, the following sequence of events should occur:
1. When power is first applied, verify that the Power LED initially displays red to indicate that
the self-test procedure is running (see the ADSL2+ Modem Router Setup Manual for an
illustration and explanation of the LEDs).
2. After approximately 10 seconds, verify that:
a. The Power LED changes color from red to green.
b. The Ethernet LED is lit to indicate that the modem router is connected to your PC or
router.
c. The ADSL LED is lit, indicating that your modem router is synchronized to your ISP’s
DSLAM.
d. The Internet LED is lit to indicate that you have an Internet connection.
If any of these conditions does not occur, refer to the appropriate following section.

Power LED Is Off or Never Turns Green

The following table provides troubleshooting tips for situations when the Power LED is off or
never turns green.
Note: If the Internet LED is off, it might not mean that you do not have an
Internet connection. It means that you do not have an Internet connection
through the PPP. When you connect the Internet using IPoA or bridging,
the Internet LED will not light up.
