The Cisco DPC3825 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 faster than ever deal!

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 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 now be on a page like the one you see here. The things you need to change are:

  • The Wireless Network should be Enabled.
  • The Wireless Configuration needs to be set to Manual. We strongly recommend not using Wi-Fi Protected Setup. Please read our guide on the topic for more information, What is WPS.
  • Leave the Network Mode at the default setting of B/G/N Mixed.
  • The Radio Band can be left at the default of Enabled 2.4GHz.
  • The Channel Width can be left at it's default as well.
  • The last thing on this page is the Standard Channel. Make sure to use channel 1,6, or 11. These three channels are the most you can get out of the spectrum without overlap. Overlap causes a lot of interference. For more on this subject, click the link titled WiFi Channels.

Once you are finished with these settings, click the button near the bottom of the page labeled Save Settings.

Now, click the tab of Wireless Security near the top of the page.

This is the wifi security page from your Cisco DPC3825 router.

On this new page, the things that need to be changed are:

  • The Wireless Security Mode should be set to WPA2-Personal. To learn more about this topic, click the link titled WEP vs. WPA.
  • Set the Encryption to AES. This is the strongest encryption available.
  • Now enter the Pre-Shared Key. This is the password you use to access the network. This password should be strong. We recommend at least 20 characters. Don't use any real words in this password, these are easily cracked. For help in creating a strong password, click the link titled Choosing a strong password.
  • Leave the Key Renewal at the default of 3600. This is how often the router creates a new encryption key from your password.

Click the Save Settings button and you are finished.

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.
