WiFi Terms

Before we get started there is a little bit of background info that you should be familiar with.

Wireless Name

Your wireless network needs to have a name to uniquely identify it from other wireless networks. If you are not sure what this means we have a guide explaining what a wireless name is that you can read for more information.

Wireless Password

An important part of securing your wireless network is choosing a strong password.

Wireless Channel

Picking a WiFi channel is not always a simple task. Be sure to read about WiFi channels before making the choice.


You should almost definitely pick WPA2 for your networks encryption. If you are unsure, be sure to read our WEP vs WPA guide first.

This is the wan page from your Asus RT-N66U router.

You should be brought to a new page.

We'll only be making changes in the Wireless (2.4 GHz / eth1) section of the page.

First you'll need to set an SSID. This will serve as your network identification and can be anything you like. However, due to security reasons we strongly recommend avoiding the use of any personal information. To learn more visit our Wireless Names Guide.

Next open the drop down menu labeled Channel and choose either 1, 6, or 11. Want to know why these are the best options? Read our WiFi Channels Guide to find out.

After that set the Security to WPA2-PSK or WPA2-Personal. If these aren't options we strongly suggest updating your firmware. To learn why this is important check out our WEP vs. WPA Guide.

Finally, choosing the correct security option should cause a box labeled Password, Passphrase, or Pre-Shared Key should appear. This will serve as your password and can be whatever you want it to be. However bear in mind that a strong password is 14-20 characters in length and includes no personal information. For more help take a look through our Choosing a Strong Password Guide.

That's it! Just don't forget to save your changes before leaving 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.
