Wireless network routers can be encrypted to provide maximum security. Most of them use the encryption protocols, WEP, WPA, or WPA2. Out of all of these, WPA2 is the latest and proves extremely difficult to crack, while WEP can be brute-forced in a matter of seconds.
To secure a wireless network router, you will first have to find its local IP address usually listed on a label on the wireless modem. Then, type this into an internet browser on a computer that is connected to the wireless network. When it prompts you for a password, look in your user manual or on the manufacturer's website for the default username and password combination.
Once on the router's home page, look for something that says or is similar to Wireless Settings and then click on advanced settings or advanced security settings. From here, you will be able to choose between which type of encryption you would like to pick, WEP, WPA, or WPA2. WPA2 is the newest, and recommended form of security for a wireless modem, as it is much more difficult to crack.
After you have selected the type of encryption and typed in a password, you will have to reconnect to your network from all the computers that were previously connected by using the key that you set up. The computer should automatically remember the network key and connect to it automatically if the router's signal is broadcasting.
