You should end up on the page you see here. First, find the box labeled Wireless Network Name. This is the name you are going to use to identify your wireless network. Be creative here, but avoid using personal information. To learn more about this topic, read our Wireless Names Guide.

Next is the Wireless Channel. If you want to change the channel, you must first uncheck the box labeled Enable Auto Channel Scan. Then above that, choose the channel you want to use. Everyone should be using channels 1,6, or 11. To learn why, read our WiFi Channels Guide.

Scroll down the page a little farther and find the box titled Security Mode. From the pull down menu choose the option of Enable WPA2-Personal Security. If you want to know more about the security options available to you, read our WEP vs. WPA Guide.

The next box that needs to be filled out is the Cipher Type. You have the option of TKIP which is an older version of encryption with some known flaws. You can also choose AES which is newer and considered a very secure form of encryption. We recommend using AES.

Next is the PSK/EAP. Select PSK from the drop down list.

In the Passphrase box, enter the password you want to use to gain access to your wireless network. This password is also used in the encryption method. Use at least 14-20 characters in your password and a mix of letters, numbers, and symbols. To learn more about this topic, read our Choosing a Strong Password Guide.

Re-type the password in the box labeled Confirmed Passphrase.

Click Save Settings and you are finished.
