Securing Your Wireless Network
Having adequate security should always be a priority when setting up a wireless network. Follow these tips to make sure no one can steal your Internet connection, or access your computers.
Change the administrative password to your router. This password is usually found in the Security menu.
Use WPA2 encryption with a pre-shared key. You can find this in the wireless setup menu.
Choose a pre-shared key that has some numbers and capital letters. The key should be at least 6 characters long.
Don’t use the default SSID. This is also in the wireless setup menu.
