How to Block Someone Using Your Wi-Fi
Creating a Wi-Fi connection in your home allows you to connect multiple devices, such as laptops, gaming systems and Blu-ray players, to your high-speed Internet connection. However, once you begin transmitting your high-speed connection through the air, anyone within a certain distance from your home can use your Internet. The more people using your connection, the slower it becomes. To avoid others using your Wi-Fi connection, you need to secure your network so you control which devices have access.
Things You'll Need
- Wireless router
Access your router's configuration page to set up your wireless connection. Each router manufacture uses its own Web address for this. Each one begins with http://192.168 and is listed by manufacturer on the Microsoft website.
Log in to your router with the manufacturer-based username and password. Most router manufacturers use "admin" as the username and "admin" as the password. Check your the Microsoft website for exceptions.
Assign your Wi-Fi connection its own identification tag. This tag can be any combination of letters and numbers. This identifies your wireless connection to potential wireless devices.
Select WPA access for your wireless connection. WPA is the most secure connection option and is preferred. However, if your hardware does not allow it, WEP can work as well.
Input a security key and pass code that will be required to access your Wi-Fi network. Any device that doesn't enter the proper security key and code cannot use your wireless connection. Record this information in a safe place away from your computer.
Save your new settings to create your secure connection. Once you have entered your security settings, you need to configure each of your wireless devices so they can access your wireless connection.
Tips & Warnings
- Choose a security key and pass code that is not easy to guess, such as words from the dictionary, special dates, your address or commonly-used words. Instead, use a combination of letters and numbers for maximum security.
- Your individual router may be able to deny access to a specific device if it came with software that permits it to do so.
