In this guide I will show you how to reset the Arris DCX3635 router back to factory defaults. This is not the same thing as a reboot. A reboot is simply turning the device off and back on again. A reset erases every setting you have ever changed and returns it to factory defaults.
Warning: A reset should be a last resort. All your previously changed settings are erased. These include:
- the router's username and password.
- the wireless settings including the SSID and the Internet password.
- If you have DSL Internet, you need to re-enter the ISP username and password. Call your ISP for this information.
- all other settings including the WiFi security and any IP addresses you have changed.

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.
The first step in a reset is to find the reset button. For the Arris DCX3635 router you can find it on the back panel. It is a tiny red button and should be on the right side of the back panel.
Take a pin or unfolded paperclip and press down on the reset button for about 10 seconds. This begins the reset process which can sometimes take up to several minutes to complete.
DO NOT unplug or turn off the router during the reset process. Doing so can cause permanent damage to the device, making it useless.
Please remember a reset like this one erases every single setting you have ever changed in the past. I strongly recommend exhausting all other troubleshooting options before you continue.
Login to the Arris DCX3635
Once the reset is complete and the router has turned itself back on (this can take several minutes or longer) you can login to the router interface using the router's default information. This information can be found in the Login Guide for the Arris DCX3635 router.
Change Your Password
After a successful login it is highly recommended that you create a new password for your router. This is not the same thing as the WiFi password. To help you with this, we have a Choosing a Strong Password guide you can read.
Tip: One way to avoid losing this password is to write it down on a slip of paper and attach it to the bottom of the router for next time.
Check the WiFi Settings
It is also very important that you check the WiFi settings. Some router manufacturers leave the WiFi security open by default. This needs to be changed immediately. We recommend using WPA2 encryption with a strong Internet password.
