Troubleshooting

This chapter gives information about troubleshooting your WGT624 v4 wireless router. After each 
problem description, instructions are provided to help you diagnose and solve the problem.

Basic Functioning

After you turn on power to the router, the following sequence of events should occur:

1.

When power is first applied, verify that the Power LED is on.

2.

After approximately 10 seconds, verify that:

a.

The Local port LEDs are lit for any local ports that are connected.

If a port’s LED is lit, a link has been established to the connected device. If a LAN port is 
connected to a 100 Mbps device, verify that the port’s LED is green. If the port is 10 
Mbps, the LED will be amber.

b.

The Wireless port LED is lit. 

c.

The Internet port LED is lit.

If any of these conditions does not occur, see the appropriate following section.

Note: 

Product updates are available on the NETGEAR website at
