The Buffalo WCR-GN 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.

This takes you to the page you see above.

First, open the drop down menu labeled Wireless Channel and set it to either 1, 6, or 11. To learn why these are the best options, take a look at our WiFi Channels Guide.

Now, beneath the SSID1 heading, you'll need to set your SSID. Select the radio button labeled Enter and then enter your desired network name into the provided box. This can be anything you like, however, due to security reasons, we strongly recommend that you avoid any sort of personal information. For more on this topic, be sure to see our Wireless Names Guide.

After that, set the Authentication to WPA2-PSK. To find out why this will give you the strongest security, check out our WEP vs. WPA Guide.

Next, set the Encryption to AES.

Lastly, you'll need to set a WPA2-PSK(Pre-Shared Key). This will be your network password and can be anything you like. However, we know that a strong password can be difficult to think up on your own, so we've created a guide to help you out.

That's it! You're done. Just be sure to click Apply 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.
