Extenders, which is basically also a repeater, only helps in distribution of wifi signal across wider areas but splits your bandwidth into two. Half of your bandwidth will be used to communicate between your main router and the extender and the other half to the clients/connected devices. In short, you will have wider coverage but weaker signals. The solution I am using at home is by adding an Access Point (AP) or lan to lan cascading. That is 2 routers connected to each other via cable (Cat6). Each router sends the same wireless signal strengths coming from a cabled source. But to resolve my cabling issue to connect 2 routers between 2 different rooms (even between ground flr and 2nd flr), I am using a gigabit powerline adapters...
