On this new page, we strongly recommend disabling all the WPS options. To learn why WPS is a bad idea, read our What is WPS guide.

Scroll down and find the section titled Manual Setup AP.

The first box is titled Select SSID. Use the drop down menu to choose the network name you created earlier.

The next box you need to change is the Network Authentication. Our recommendation is WPA2 PSK. To learn why this is the best option, check out our WEP vs. WPA guide.

Now find the WPA/WAPI passphrase. This is the password you are going to use to access your network. This should be a strong password of at least 20 characters. To learn how to create a strong and memorable password, read our Choosing a strong password guide.

The last thing you need to check is the WPA/WAPI Encryption. There are a couple choices, TKIP or AES. We recommend AES, it is more secure than TKIP.

Congratulations, you are done. Just don't forget to click the Apply/Save button.

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.
