decrease wi-fi single

How can I decrease my wi-fi single my nabor called me and said I was blocking her single I told her I do not see how anyway is there a way to decrease it. I'm on a Router.

Umm... I dunno if this will work, but try decreasing the signal radius in your router configuration. Normally, to access your router's configuration page, go to http://192.168.1.1 assuming you know the username and pass, which in most cases, admin is the default for both.

It would be useful if you check your router's manufacturer site for more info.

Thanks for your help I do not know what this is could this be what I need to play with to decrease my wi-fi single.
