Different Range Extenders may behave differently on RE light.

For example, the RE/WPS LED of TL-WA850RE will keep solid “on” after a successful configuration while RE200’s RE LED will just last “on” two minutes and be off. So if you want to gain more information about Range Extender’s working status, the signal LED lights are the best choice.


Part B: If you have configured the Range Extender.

The Signal lights will give you the exact information that whether you have configured your Range Extender successfully. Once the range extender has connected to the router, the Signal light will be solid “on” (no matter what color it is or how many signal bars there are).

The color or number of signal lights indicates the signal strength that RE gets from the main router, which is just used to help you choose the best location for your RE.



  1. First, RE light of Range Extender is just used to indicate the WPS process. After you press Range Extender’s RE/WPS button, the RE light will start blinking. After several minutes, if RE light becomes solid on, it means WPS process is successful.


  1. Second, Signal lights of Range Extender will accurately tell you whether your Range Extender has successfully connected to the wireless router or not. So in most cases, you just need to check RE’s Signal lights to see if you have successfully configured your Range Extender.
