Hello @bill-lancaster ,

Thanks for contacting our community.

Powerline Adapters can be affected by various factors,here are some troubleshooting steps you can try:
1. Place your Powerline Adapters as far as possible from high-power appliances, such as AC units, refrigerators, or washing machines.
2. Power off high-power appliances one at a time to see if any of them are causing the issue. If you identify a problematic device, try to keep it turned off or use a surge protector with filtering capabilities.
3. Avoid plugging your Powerline Adapters into surge protectors or extension cords. For best performance, plug them directly into the wall outlet.

If these steps do not help, please feel free to contact local technical support for further assistance.
