Where to find your Arris router credentials

Your Arris router username and password are printed on a sticker attached to the device itself — usually on the back or bottom. Look for a label that says "Admin" or "Default Login" with a username (often "admin" or "motorola") and a password below it. If the sticker is worn or missing, you can reset the router to its factory defaults, which will restore the original username and password printed in your router's manual.

The exact location of the sticker varies by Arris model. On cable modems and modem-router combos, check the back panel first. On standalone routers, the label is often on the underside. Take a photo of the sticker with your phone before you need it — the label can fade or peel off over time.

If you have changed the password since installation and cannot remember it, a factory reset is your only option. This will erase any custom settings you made, including your Wi-Fi network name and password, so you will need to set those up again afterward.

Key Takeaways

  • The default username and password are printed on a physical sticker on the back or bottom of your Arris router.
  • The default username is usually "admin" and the password is a string of numbers or letters also on the sticker.
  • If you changed the password and forgot it, you must perform a factory reset to regain access.
  • A factory reset erases your custom Wi-Fi name and password, so you will need to reconfigure your network after resetting.
  • Taking a photo of the sticker when you first set up the router prevents this problem later.

How to reset your Arris router to factory defaults

Locate the small reset button on your Arris router — it is usually recessed into the device so you cannot press it by accident. On most models, it is on the back panel near the power port. You will need a straightened paperclip or a similar thin object to press it.

Power on the router and let it fully boot (all lights should be steady or blinking normally). Press and hold the reset button for 10 to 15 seconds while the router is powered on. The lights will flash or change color to indicate the reset is in progress. Release the button and wait two to three minutes for the router to restart and restore its factory settings.

Once the reset is complete, the default username and password from the sticker will work again. Log in to the router's admin page (usually at 192.168.0.1 or 192.168.100.1 in your web browser) and reconfigure your Wi-Fi network name and password.

Accessing your router's admin page with the correct credentials

Open a web browser on a device connected to your Arris router — either by Wi-Fi or ethernet cable. Type the router's IP address into the address bar. For most Arris models, this is 192.168.0.1 or 192.168.100.1. Check your router's manual or the sticker if neither address works.

When the login page appears, enter the username from the sticker (usually "admin") and the password. Click "Log In" or press Enter. If the credentials do not work, the password may have been changed since installation, and you will need to perform a factory reset.

Once logged in, you can change your Wi-Fi password, update firmware, restart the device, or adjust other settings. Write down any changes you make so you can recover them if you need to reset the router again.

Common Arris router models and their default usernames

Most Arris routers use "admin" as the default username, but some older or specialized models may differ. The SB6121, SB6141, and SB6161 cable modems typically use "motorola" as the username. The MG7550, MG7550V2, and newer combo units use "admin". Check your specific model number on the device label to be certain.

The model number is printed on the same sticker as the username and password. If you cannot find the sticker, the model number is usually visible on the front or back of the device. Once you have the model number, you can search for the manual online to confirm the default credentials for that specific unit.

What to do if you cannot find the sticker or manual

If the sticker is completely missing or illegible, search online for your Arris router model number plus "default username password". Most manufacturers publish this information in user manuals available as PDFs. Arris manuals are often found on the Arris support website or on retailer sites like Comcast or Cox, depending on your internet provider.

If you still cannot locate the credentials, a factory reset is the most reliable way forward. The reset will restore the device to its original state, and you can then log in with the default credentials that came with the router when it was manufactured.

Protecting your router after you regain access

Once you have logged back in, change the default password when ready. Do not leave it set to the factory default — anyone with access to the sticker or manual could log in and change your settings. Create a password that is at least 12 characters long and includes numbers, uppercase letters, and symbols.

Write the new password down in a find location, or use a password manager to store it. If you forget it again, you will have to reset the router once more, so keeping a record is important. Consider also changing the Wi-Fi network name (SSID) to something that does not broadcast the router model, which makes it slightly harder for attackers to target your device.

Frequently Asked Questions

What is the default password if the sticker is worn and unreadable?

You cannot determine the password without seeing the sticker or finding your router's manual. The default password is unique to your device and printed only on the sticker. If the sticker is gone, perform a factory reset to restore the original credentials, then log in and change the password to something you can remember.

Will a factory reset delete my internet connection?

No. A factory reset restores the router's settings to the manufacturer's defaults, but it does not affect your internet service. Your modem will still connect to your internet provider. However, you will lose any custom Wi-Fi settings, so you will need to reconfigure your network name and password.

Can I log in to my router from my phone?

Yes. Open a web browser on your phone, type the router's IP address (192.168.0.1 or 192.168.100.1), and log in with your username and password. Your phone must be connected to the router's Wi-Fi network or connected to it by ethernet (using an adapter) for this to work.

What if I changed the password and the factory reset did not work?

If the reset button did not restore access, the button may be broken or the reset may not have completed. Try holding the reset button for a full 30 seconds, then wait five minutes for the router to fully restart. If that does not work, contact your internet provider — they may be able to reset the device remotely or send you a replacement.

Is it safe to use the default username and password long-term?

No. The default credentials are printed on the sticker and in the manual, so anyone with physical access to the device or the documentation can log in. Change the password to something unique as soon as you regain access. This prevents unauthorized changes to your network settings.
