Basic Troubleshooting Procedure

This procedure addresses a number of symptoms that you might experience with your router and wireless connection:

Verify the physical cable connections between your router, your computer, and your modem.
Ensure that the power outlet to which the router is connected is a live outlet.
Refer to the LED descriptions and then check the LEDs on the router to make sure you are receiving power and that are no errors.
For wired connections: The Power and WAN LEDs should be lit, and the corresponding LAN LED that your computer is plugged in to should be lit.

For wireless connections: The Power, WAN and WLAN LEDs should be lit.
Restart your cable or DSL modem. After the LEDs on the modem have stabilized, press the Reset button on the back of your router for 1 second to restart your router. Then, restart your computer.
Other devices connected to the router may need to re-establish their network connections.
Some electronic devices, such as 2.4GHz - 5.8 GHz phones and microwave ovens, may interfere with the wireless signal and affect your wireless range and link quality. Try creating a wireless connection on a different channel.
Low link quality or range can be caused by environmental interference, such as lead-based paint and concrete walls. Try to move the antenna of the router or to reposition the wireless clients to improve the link quality. If possible, ensure that there are no obstructions between wireless clients and the router.

If you still have trouble using the router, follow the procedure below that best describes your symptom.
