Adding wifi booster

[wireless]

Hi I am trying to add a wifi booster to my network. When I hit add wifi booster from the app I keep getting a message that says " You need to be on your home wifi and enter admin password to proceed. Please ensure that you are connected to your wifi and reopen the app to try again ". I am indeed on my home wifi and it still keep showing the same message even after re installing the app. Please help.
