Powerline Connections: Powerline (PL) LED color indicates the strength and
quality of the Powerline connection through the electrical system. The following
factors may affect the Powerline network’s connection quality:
• Noise – Generated by appliances which use your electrical system (e.g.
Microwaves, ovens, hair dryer, irons, dishwashers, etc.). The quality of your
household electrical wiring may also cause additional noise on your electrical
system.
• Distance – Long lengths of electrical wiring through your electrical system
between connected Powerline Adapters.
