How to Reset the Dell SonicWALL TZ-150

On this page I will show you how to reset the Dell SonicWALL TZ-150 router back to factory defaults. This is not the same thing as a reboot. When you reboot your router you cycle the power to the device. This is done to solve minor problems such as an unresponsive router. To reset a router means to erase all previous settings and return them to factory defaults.

Warning: Resetting this router is a big step and should not be taken lightly. We recommend making a list of the settings you know will be changed. Consider the following:

• The main username and password for the router are reverted to factory defaults.
• If you use a DSL router you need to re-enter the ISP username and password. Call your local Internet Service Provider for more information.
• If you have ever made any other changes to your device you need to write these down so you can reconfigure them after the reset is complete.

Reset the Dell SonicWALL TZ-150

Use a VPN

Have you considered using a VPN when you connect to the internet? A VPN is a great way to increase your security and anonymity while surfing.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes securely sharing your home network super simple. 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.

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.

Begin by locating the reset button on the device itself. For this Dell SonicWALL you can find it on the back panel. We have circled this tiny recessed button in the image below.

Take the tip of a pin or unfolded paperclip to press and hold the reset button down for at least 10 seconds to start the reset process. If you don't hold the reset button down for long enough it will only reboot the router instead of resetting it.

Don't forget that this WILL erase every setting you have ever made to the router. To avoid that you should try other troubleshooting methods first.

Login to the Dell SonicWALL TZ-150

Now that you've reset your Dell SonicWALL TZ-150 router you'll need to log into it. Do this with the default username and password. Don't know what these are? We've got you covered. They're listed for you in our Login Guide.

Tip: If the defaults don't seem to be working for you, don't panic quite yet. It may be because you didn't hold the reset button down for long enough.

Change Your Password

After that we recommend changing the default password. For help creating a strong password visit our Choosing a Strong Password Guide.

Tip: To keep from losing your password try writing it on a sticky note and putting it on the bottom of your router.
