This directs you to the page you see here. First, we recommend using the section titled Wireless Netework (2.4GHz b/g/n).

In this section, find the Name (SSID) and change it to something you pick. While it doesn't really matter what you enter here we recommend avoiding personal information. Check out our Wireless Names Guide for more information.

Now take a look at the Channel. There are quite a few different channels to choose from but we recommend using only 1,6, or 11. Find out why in our WiFi Channels Guide.

Below that is a section titled Security Options. For the best security choose the option of WPA2-PSK[AES]. Take a look at our guide to learn why, WEP vs. WPA.

Once you have done this you need to enter a Passphrase. This is the network password you use to access your local internet. This password is an important part of your security and should be strong. To create a strong password use at least 14-20 characters an a mix of numbers, letters, and symbols. Take a look at our Password Guide for more help on this topic.

Click the Apply button when you are finished.

Congratulations, you did it.
