Now, click the button in the center section of the page labeled Wireless Basics. This should take you to a page that unfortunately we do not have.

The first thing you need to do is change the SSID. This is the name you give your wireless network so that you can identify it later on. Be creative here, but avoid personal information. This name can be seen by your neighbors with wireless devices. To learn more about this topic, read our guide on it by clicking this link.

Then, click Save/Apply when you have finished this.

Now click the option in the left sidebar titled Wireless Security.

On this new page, use the drop down menu titled Network Authentication to choose the best security option for your network. We recommend the choice of WPA2-PSK. To learn the differences in the options, read our guide on the topic, WEP vs. WPA.

Next is the Encryption Key PSK. This is the password you use to access your network. It is also used in the encryption method so it needs to be strong. We recommend using at least 14-20 characters with a mix of numbers, symbols, and letters. This can be a lot of fun. To learn how to create a strong password that is memorable, read our guide titled Choosing a Strong Password.

You can also change the WPA Encryption if you like. There are two different choices you can make. TKIP, which is a little older and has been cracked, or AES, which is newer and is considered more secure.

When you are finished, save your changes before you exit.

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.
