In this guide we will cover how to reset the Arris TG852 router. Resetting a router is not the same thing as rebooting a router. A reboot consists of turning the power off the the router and turning it back on to cycle the power. Resetting a router is done easily enough but has more consequences attached to it.

Warning: A reset can cause problems if you don't know what changes. Please consider the following.

  • The router's main username and password are reset.
  • The Internet username and password are reset as well.
  • If you use a DSL connection you need to re-enter the ISP (Internet Service Provider) username and password if you want to reconnect to the Internet. For more details call your ISP.
  • All configurations that you have made are erased. This could include port forwards, firewall settings, and even IP address changes.

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.

The very first step in any reset of a router to make sure it remains on during the entire process. If you switch it off or unplug it for any reason during the reset process you could permanently damage your router.

The next step is to locate the reset button. It will be very small and usually is located on the back panel. We have circled it's location for you in the image below.

The last setting we urge you to check is the security settings. Some router companies like to leave the network security open. This means your Internet network is open to anyone who is in range. You need to change this so people have to get your permission first. Change your WiFi security to WPA2-PSK. If you need help check out our How to Setup WiFi on the Arris TG852 guide.
