The Buffalo WZR2-G300N 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.

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.

wifi wireless
This is the wifi setup page from your Buffalo WZR2-G300N router.

This akes you to a page like the one you see here.

  • The Wireless Radio should be Enabled.

  • The Wireless Mode needs to be set to Wireless-BGN. This is the different types of wireless devices that can connect. B is the oldest dating to 1999, G devices were created in 2003, and N devices were made after 2009

  • Next is the SSID. This is the name you give your network so you can identify it later. First, tick the dot labeled Use. Then in the box to the right, enter an appropriate name. This name can be anything you like, just avoid using personal information as this may make you more of a target. For a more detailed guide on this topic, click the link titled Wireless names.

  • Below that is the Wireless Channel. There is only room in the spectrum for up to three channels that don't overlap. If you have any neighbors at all, to avoid interference, use channel 1,6, or 11. For more on this topic, click the link titled WiFi Channels.

  • Leave the Channel Bonding at it's default setting.

  • The last thing on this page is the Broadcast SSID. If you check the box titled Allow, all wireless devices in the area can see your network name. If you choose to not check this box, your wireless name is hidden from scanning wireless devices. This is camouflage, not invisibility. Your network still sends out information, and hackers can still find your network fairly easily. You are just a little less of a target.

  • Click the Apply button.

Next, click the link titled Security at the top of the page. Note that their are two securities at the top of the page. The one you want is under the heading of Wireless Config.

You are taken to the page you see above.

  • The first setting is Wireless Authentication. There are several different options here. The best is WPA2-PSK. To learn why, click the link titled WEP vs. WPA.
  • Next is the Wireless Encryption. It looks as if when you chose WPA2-PSK, the encryption automatically chooses AES for you. This is a great choice. AES is the most secure choice for home networks.
  • After that is the WPA-PSK (Pre-Shared Key). This is the password you use to access your network. This is also used in the encryption method. It is important that you create a strong password of at least 20 characters. A good password has at least one symbol, number, and capital letter within it. You need to avoid using personal information because this can be much easier to guess. Don't use any words that are in a dictionary, these passwords are much easier to crack with programs that are designed to check for dictionary words very quickly. For more on creating a strong and memorable password, click the link titled Choosing a strong password.
  • The Rekey interval is how often you want your router to create a new encryption key from your password, most likely the default is fine. It should be somewhere around 60 minutes.
  • Finally, click the Apply button.

That's it, congratulations.

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.
