On this page, use the Security Mode drop down list to choose WPA2 Personal. For more on this topic, read our guide titled WEP vs. WPA.

Next is the WPA Algorithm. There are three choices here, TKIP, AES, or both. Our recommendation is AES. This is the strongest option available today.

Lastly, is the WPA Shared Key. This is the password you use to access your network. Make sure this password is at least 20 characters long. We recommend using a few symbols, numbers, and capital letters. Don't use personal information or any words that can be found in a dictionary. for more information on this, read our guide titled Choosing a strong password.

That's all you need to do, just click Save and you are finished.

Possible Problems when Changing your WiFi Settings

After making these changes to your router you will almost definitely have to reconnect any previously connected devices. This is usually done at the device itself and not at your computer.
