This article covers how to reset the Arris DG9450 router back to factory default settings. A router reset is a much bigger deal than a router reboot. Unplugging a router from the wall reboots it. Resetting a router erases all settings from it and returns it to factory defaults.
Warning: This is not a step to be taken lightly. The following settings will be changed in your router:
- The router's login credentials are reset.
- Your WiFi login, password, and network name are reset.
- All ISP settings will reset to default, and you may have to contact your ISP.
- Any parental controls, firewall settings, or port forwards will be removed.
Resetting your router should be considered the last step. Make sure that you have tried to recover your router password using our Router Password Finder first.

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.

Usually there is a reset button located on the back or bottom of a router. Look for something that looks like this:
Even though yours may look slightly different, you need to look for a tiny button. If you find a pinhole on the back of the router then that may be the reset button. You will need a paper clip to push it.
Keep an eye on the lights on the front of your router while holding the reset button down for about 10 seconds. The lights on the front of the router should do something different when the reset happens. It is harmless to hold the reset button too long.
Remember, this will erase everything you have previously done to this Arris DG9450 router.
Only take this last step of fully resetting your router after you have exhausted all other troubleshooting options, such as running our Router Password Finder software, which can recover a lost router password for you.
Login to the Arris DG9450
After you are finished resetting your router, you need to login in using the original factory username and password. You can follow the DG9450 Login Guide to find everything that you need to log in.
Change Your Password
You need to change your router's default password after you log in for the first time. It is a huge security risk to leave your router's password set to the factory default. Our Choosing a Strong Password guide talks about choosing a strong password for your router.
Tip: After creating this new password, we highly recommend writing this down on a post-it note and attaching it to the bottom of your router for future reference.
