23.4 Powerline Issues

I cannot start my powerline device.

1 Check your power supply. Powerline adapters operate from the power supplied by your

home wiring and cannot operate without a working power supply.

2 Make sure that you are using the power cable included with your P-660HWP-Dx to

attach your P-660HWP-Dx to the power supply. Standard plugs do not have a powerline
network capability.

3 Remove the P-660HWP-Dx’s plug from the outlet. Then plug an electrical device that

you know works into the same power outlet. This checks the status of the power outlet.

4 Plug a second HomePlug AV adapter into an outlet adjacent to your P-660HWP-Dx and

see if the Link

LED lights up. This checks whether the P-660HWP-Dx can detect the

powerline adapters on your electrical circuit.

I cannot access my powerline network.

1 Make sure that the devices on your network are all on the same electrical wire.
2 Check also that the network does not extend past the power meter. Powerline signals

cannot pass this.

3 Make sure that all the powerline adapters you are using are HomePlug AV compliant.

The P-660HWP-Dx does NOT recognize earlier versions of HomePlug powerline
adapters such as HomePlug 1.0 or 1.0.1. (Although they can coexist on the same
network.)

4 Make sure that the network password is the same on all of your powerline adapters.

The signal on my powerline network is weak.

1 Do not plug the devices in electrical surge protectors, as they may decrease the

powerline signal.

2 Place the powerline devices away from appliances such as refrigerators or air-

conditioners that consume a lot of power.

3 Place the powerline devices away from electrical insect-killers as the radio waves will

interfere with the powerline signals.
