P-660HWP-Dx User’s Guide

• Check the settings for bandwidth management. If it is disabled, you might consider 

activating it. If it is enabled, you might consider changing the allocations. 

V

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.

V

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.

V

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.
