Assuming that you already have a router set up at home,

1. Secure your access to the admin page of your router with a complex password. A complex password contains a mixture of letters, numbers and symbols. E.g. (Compl3xPa55word) is a complex password.

2. Give your wireless router a SSID name and set it not to broadcast the SSID. This means anyone who wants to connect to your router must already now the SSID name before he can connect his computer to your router.

3. Set your router's wireless security to use WPA or WPA2 encryption. See the resources below on how to set this for various models of routers.

4. If you really, really want to secure your wireless network such that only your authorised computers can connect to, you can configure your router to only allow the MAC addresses of your computers to connect to your network.

Reference http://discovervalue.com/configure-wireless-router-security and see if your router is listed there. If found, follow the instructions to set the WPA security encryption.
