phone can connect and use N300 wifi range extender but laptop cannot connect at all

[skygod3286]

I've installed wifi range extender sucessfully.

I can use this extend wifi to my phone, printer and other devices.

However, only the laptops (I have two laptops; lenovo and toshiba) cannot use this extend wifi at all.

Even the laptop find the wifi but just cannot connect. When I connect the extend wifi, it shows that "cannot connect to this network".

Regular wifi is working but it is very slow to use. 

How should I fix the problem to use faster wifi?

Hello Skygod3286

Did you name the extender the exact same as the main routers SSID if you did it could be causing a conflict with your laptop trying to use the routers settings with the extender you may want to change the SSID if so. Also make sure you are using WPA2 security.
