Netgear XAV5004 – 4-port Powerline AV 500 Adapter 用户手册

Verify that the wall socket is live. To do this, disconnect the Powerline adapter and plug in 
another electrical product, such as a lamp or a hair dryer.

If the Power LED still does not come on, and you have confirmed the power outlet is live, you 
have a hardware problem and should contact technical support.

If the power light is on but the Powerline light is not, check the following:

Make sure that power is being provided to more than one Powerline device. Another 

Powerline device must be installed for successful communication across the Powerline.

Verify that the network password is the same on all devices in the Powerline network.

Make sure that the Ethernet cable is plugged in properly at both ends.

Be sure that you are using the correct cable on the router that the first Powerline adapter 

is connected to. When connecting the router’s Internet port to a cable or DSL modem, 
use the cable that was supplied with the cable or DSL modem. This cable could be a 
standard straight-through Ethernet cable or an Ethernet crossover cable.

On the attached Ethernet device or network adapter card, check that the Link LED is on.

Troubleshooting Tips

The following table lists problems and recommendations.

Power LED is off.

Make sure that power is supplied to the electrical outlet, and the Powerline 
device is not plugged into an extension cord, power strip, or surge protector.

Powerline LED is off.

The devices cannot find each other. Make sure that the Powerline devices are 
plugged into outlets with power, and that they use the same network encryption 
key. 

• If you did not change the network encryption key, move the Powerline device 

to a closer location.

• If the problem occurred after you changed the network encryption key using 

the XAV5004 Powerline Utility, press the Factory Reset button to return the 
Powerline adapters to their default settings. If this fixes the problem, see
