  1. Is the Power light illuminated?

  2. Is the WAN light illuminated?

  3. If the D-Link router is connected to your computer using an Ethernet cable, are any Local Network lights illuminated (E1, E2, E3, or E4)?

  4. If your computer uses a wireless network adapter to connect to the network, is the WLAN light illuminated?

    • Reboot your computer by turning it off, waiting for 45 seconds, and then turning it back on. Re-check your router lights.

    • Disconnect all networked computers and restart the computer connected to the router. Reconnect the other computers one-by-one to isolate the problem.
