Troubleshooting
The Wireless Router is plugged in, but the Power light is Off
Check all power connections. Is the power cord plugged in firmly at both ends?
If you plugged the power cord into a power strip, make sure the strip is switched on.
Avoid using an outlet controlled by a wall switch, if possible.
Finally, check the fuse or circuit breaker panel.
I'm not getting on the Internet (all connections)
It may take several minutes to establish a connection the first time you power up the
Wireless Router, especially when many people are online. Always leave the Wireless
Router plugged into AC power and connected to the modem.
Check the front panel lights:

The Power and WAN lights should be on.

If the Power light blinks for more than 30 minutes, call your service provider for
assistance.
Check the cable connections. Connectors should be tight. Cables should not be pinched,
kinked, or bent sharply—any of these can cause a break or short in the cable (you may have
to replace the cable).
Proceed to the Ethernet or wireless solutions if necessary.
I'm not getting on the Internet (Ethernet)
If you are using a switch, is the switch turned on?
Are you using the right type of Ethernet cable? Use an RJ45 Cat5e cable for direct
connection to a computer; use a cross-over cable for connection to a switch.
Press the Reset button on the back of the Wireless Router.
A misconfiguration could lock out all access to the Wireless Router. If you think this has
happened, see Resetting the Wireless Router to Factory Defaults.
I'm not getting on the Internet (Wireless)
Check the indicator lights, see Using the Wireless Router — the Wi-Fi light should be on.
Does the connection utility discover your wireless LAN? If you turned off “Broadcast SSID”
you need to manually enter the name of the wireless LAN in the connection utility.
