Connect another powerline adapter into an outlet close to your PLA-4xx's power outlet. They are probably now on the same electrical wiring. Check the HomePlug light. If it now lights up your powerline adapter was probably previously on separate electrical wiring. Ask an electrician for more information on the electrical wiring in your building. 6 If your powerline network is using coaxial cable, check all powerline adapters are on the same coaxial cable. 7 If your powerline network is using electrical wiring (not coaxial cable), check you do not have a power meter between powerline adapters. Powerline signals cannot pass this. V The POWER and HomePlug light blink at the same time. 72 PLA-4xx Series User's Guide

1
Check all PLA-4xxs on your network have the latest firmware installed. PLA-4xxs with
the latest firmware cannot communicate with PLA-4xxs using earlier versions of the
firmware. Go to
