Determining connection rate
Each colour of the Powerline Activity LED represents a connection rating. The connection rating can only be calculated when the
device is part of an existing network. The exact connection rate value can also be viewed using Powerline Utility.
Good (Red) – Connection rate is less than 30 Mbps
Better (Amber) – Connection rate is between 30 to 80 Mbps
Best (Green) – Connection rate is more than 80 Mbps
Power saving mode
After 15 minutes without Ethernet activity, the Power LED blinks slowly indicating that the adapter is in power saving mode.
