or blinking. See

5.4 Powerline Problems

The signal on my powerline network is weak.
1 Your powerline adapters may be connected to electrical surge protectors. Connect them
to standard power outlets.
2 Your powerline adapters may be located close to large appliances such as refrigerators or
air-conditioners that cause interference with the powerline signal. Move the adapters
further away from such appliances to reduce interference.
3 Your powerline adapters may be placed close to electrical devices such as electrical
insect-killers which produce radio waves. These may interfere with the powerline
signals. Move the adapters further away from such electrical devices.
4 Your wiring may be old and/or low quality or with a long wiring path.
