Thank you for your message. In case you don’t want to use cables you need to setup a Wireless Distribution System, or WDS. Please note that WDS setup is very sensitive even one missed out step can brake the connection between the main and the additional routers. You need to make sure that both routers support WDS. You should perform the steps in our tutorial on both router administrator menus of your devices. In case both routers support WDS the same options will be available.

We recommend you don’t use repeaters but buy additional cheap routers with our system and use WDS in order to extend the range of your hotspot. Please make sure that the additional routers support WDS.
The reason why we don’t recommend the use of repeaters is that after the first successful login of one user all the users behind the first user will have free internet access.
