What can I do when some specific domestic appliance affects PLC product’s performance, such as PLC device’s data transfer rate is very low or even the PLC device can’t work normally?

Various factors might affect the performance of PLC products, such as air-switch, surge protector, high-power electrical appliance and so on. All these devices can generate too much electrical noise and unstable voltage in your home powerline environment.

In this kind of powerline environment, PLC products encourter bad performance like PLC device’s data transfer rate being very low, or PLC device can’t even work normally.

Note: This kind of special powerline environment is very rare, so most of you will not encounter the problem above.


If you happen to encounter similar problems above, please try the following solutions.

  1. Place your PLC products as possible far away from domestic appliances as you can, especially those high-power electrical appliances like air-conditioner, refridgerators or washing machine.
  2. Shut down your house’s high-power electrical appliances in turn, to find out which one mainly affects the performance of PLC products. If possible, please turn off that specific appliance when you use PLC products.
  3. Plug your PLC products into a power socket directly instead of a thread plate.


If the methods above still can’t solve your problem, please feel free to contact TP-LINK technical support to figure out whether you need a replacement because of the defective PLC devices you have, or if using a PLC is not suitable to use in your special powerline environment as all brands’ PLC products will have the same problem in your house.
