PLC is a WiFi extender that amplifies the signal and enables the WiFi to reach further than before. In the case of home installations, the WiFi router is located on the first floor and if it reaches the second floor the signal is very weak. This device will solve this problem and you will never have a weak signal again because it extends the WiFi signal in any part of your house that has an electrical outlet.
