The Asus RT-N66U router is considered a wireless router because it offers WiFi connectivity. WiFi, or simply wireless, allows you to connect various devices to your router, such as wireless printers, smart televisions, and WiFi enabled smartphones.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

When shopping for a VPN, make sure that they meet the following criteria:

  • Your VPN provider should have a no-logs policy. This means that they do not keep any logs of any kind.
  • Make sure that your VPN provider has lots of exit nodes all around the world.
  • Check that your VPN will not affect your speed.
  • Verify that your VPN provider uses WireGuard as the underlying protocol.
  • Many people prefer a VPN provider that is not based in the United States.

This is the list of requirements that we used when we were shopping around for a VPN provider. There are lots of free, shady VPN providers out there that we looked at and dismissed.

Based in Panama, using diskless servers, and with over 6,100 servers in 61 countries, we can safely say that NordVPN satisfies all of these requirements.

NordVPN is the fastest VPN!

Once you've set up your NordVPN account on multiple computers and enabled Meshnet, you can seamlessly access all of your devices as if they were on the same network. You don't even have to log in to your router. It's very simple.

Every time you click on one of our affiliate links, such as NordVPN, we get a little kickback for introducing you to the service. Think of us as your VPN wingman.

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 wifi setup page from your Asus RT-N66U router.

Some of the settings on this page can be left alone, but there are a few that need to be changed as soon as possible.

  • The first is the SSID setting. This is your networks name. The name you give your network to identify it from others around you. Go ahead and create an original name here, but avoid using anything that will point to you, such as your name or address. Wireless names is our guide on the topic if you would like some more information on the topic.
  • Next is the Control Channel. You should be sure you are on the correct channel, 1,6, or 11. Overlapping channels do not communicate well with each other, so you should completely share a channel or be at least five channels away. There is only room in the spectrum for three channels that do not overlap each other, channels 1,6, and 11. Check out our guide on the topic, WiFi channels, for more information on why you should only be using one of these three channels.
  • Next, is the Authentication Method. We strongly recommend using WPA2-Personal for your home network. WEP vs. WPA is a great guide on the subject if you are interested in learning more.
  • Below that is the WPA Encryption. This is asking how you want to encrypt your data. There are two main choices here, TKIP and AES. We highly recommend using AES. It is at the moment considered uncrackable.
  • Finally, change the WPA Pre-Shared Key. Do not leave this at the default setting. This is your password you use to access your network. Change this to a strong password of at least 20 characters. Avoid using anything that is easy to guess such as personal information, and dictionary words. Dictionary words are especially easy because a potential hacker has programs that try all the dictionary words very quickly. If you need to use words, misspell them. We do suggest using capital letters in the middle of the password. Another good idea is to use symbols and numbers in place of letters. How to choose a strong password is a great guide on the topic if you would like more help.
  • When you are finished, click the Apply button before you exit.

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.
