P-660HWP-Dx Quick Start Guide
11
VIf you cannot access your HomePlug AV network, try the following:
1Make sure that the network password is the same on all of your HomePlug AV adapters
and that the DAKs for your HomePlug AV devices are typed correctly.
2Make sure that all the power line adapters you are using are HomePlug AV compliant.
The P-660HWP-Dx does NOT recognize earlier versions of HomePlug adapters such
as HomePlug 1.0 or 1.0.1.
3Plug a second HomePlug AV adapter into an adjacent outlet (to your P-660HWP-Dx)
and see if the POWERLINE LED lights up. This checks whether the P-660HWP-Dx
can detect the power line adapters on your electrical circuit.
