You gave us nothing to go off. 

what extender do you have? 

what firmware is on it? 

What actual router are you connecting it to?

What is actually going on? 

Did you set up the extender? 

What process of setup did you use? WPS? Installation assistant? The app?

Details are key to helping. 

 

There's a support site with access to manuals, firmware, install guides, etc.
