Your Belkin wireless router's security settings controls access to your wireless network, such as leaving it unsecured or encrypting it to block unauthorized access. Although it may sound like a good gesture to open up your network to all, there are too many problems that can arise from doing so, such as having your computer hacked or being responsible for another person's illegal activities. Therefore, if your network is unsecured, it's a good idea to change your security settings.
Open your browser and enter your Belkin router's IP address in the address bar. Belkin typically uses "192.168.2.1." If you previously changed the IP address, open a Command Prompt and enter "ipconfig." Look for "Default Gateway" for the router's IP address.
Click "Login" to access the administration page. By default, the password is blank, but if you previously changed the password, enter the new password.
Click the "Wireless" tab and select "Encryption" or "Security."
Click the "Security Mode" drop-down menu and select your preferred security protocol. "WPA2" offers the highest level of security, but may not be available on all routers or compatible with older hardware. "WEP" is less secure, but more compatible with older hardware.
Enter a long, complex security passphrase in the password field, if you are choosing an encryption option.
Click "Apply Changes."
