■The Router has just been started up and is running a self-test routine, or

■The administrator has invoked the Reset to Factory Defaults command, or

■The system software is in the process of being upgraded

In each of these cases, wait until the Router has completed the current operation and the alert LED is Off.

Flashing slowly — The Router has completed the Reset to Factory Defaults process, and is waiting for you to reset the unit. To do this, remove power, wait 10 seconds and then re-apply power. The Router will then enter the start-up sequence and resume normal operation.

On for 2 seconds, and then off — The Router has detected and prevented a hacker from attacking your network from the Internet.

Continuously on — A fault has been detected with your Router during the start-up process. Refer to Chapter 6 “Troubleshooting”.

2Power LED Green

Indicates that the Router is powered on.

3Wireless LAN (WLAN) Status LED Yellow

If the LED is on it indicates that wireless networking is enabled. If the LED is flashing, data is being transmitted or received. If the LED is off, the Wireless LAN has been disabled in the Router, or there is a problem. Refer to Chapter 6 “Troubleshooting”.

4Four LAN Status LEDs

Green (100 Mbps link) / yellow (10 Mbps link)

If the LED is on, the link between the port and the next piece of network equipment is OK. If the LED is flashing, the link is OK and data is being transmitted or received. If the LED is off, nothing is connected, the connected device is switched off, or there is a problem with the connection (refer to Chapter 6 “Troubleshooting”). The port will automatically adjust to the correct speed and duplex.
