You should now see a page similar to the one above.

I recommend using 2.4GHz if you are in a rural area and 5GHz if you are in a city.

In which ever section you choose make sure the Status is enabled.

Then in the box labeled Wi-Fi Name (SSID) enter the new name you want to use for your network. This is how you identify your network connection. Make this name unique but it's a good idea to avoid personal or router specific information. Learn more in our guide titled How to Change your Wireless Name.

Below that is the Password. This is the Internet password. This should be strong. Use a minimum of 14 to 20 characters. Learn how to do this in our guide titled Choosing a Strong Password.

To change the security type you need to click the blue Advanced Settings option in the lower right corner.

This opens a new section. Find the option of Security Mode. In this box pick the security you want to use. I recommend using WPA2 Personal. You may or may not have this option available by itself. If it is not available you may want to update your firmware.

When you are finished click the option of Save at the top of the page.

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.
