Where to find your Arris router's default username and password

Your Arris router's default username and password are printed on a sticker attached to the device itself — usually on the bottom or back panel. The username is almost always admin, and the password is either motorola or a string of numbers and letters specific to your router's serial number. Check the sticker first before trying anything else, because this is the fastest way to log in.

If the sticker is missing, faded, or you cannot locate it, the default credentials depend on which Arris model you own. Arris makes routers under several brand names — SB, MG, and CM series are common — and each line uses slightly different defaults. The password on the sticker is usually tied to your device's MAC address or serial number, so a generic password will not work if the sticker shows a custom one.

Write down the username and password from the sticker before you proceed. You will need them to log into the router's web interface, and if you lose them again, you may have to reset the entire device.

Key Takeaways

  • The default username for Arris routers is admin, and the password is printed on a sticker on the bottom or back of the device.
  • If the sticker shows a custom password (a long string of characters), that password is tied to your specific router and cannot be replaced with a generic one without resetting the device.
  • If you have changed the password since setup and cannot remember it, you will need to perform a factory reset, which erases all your custom settings.
  • Once you log in, you can change the password to something you choose, but write it down in a safe place so you do not lose it again.

How to log in to your Arris router once you have the credentials

Open a web browser on any device connected to your Arris network — a computer, phone, or tablet. Type 192.168.0.1 or 192.168.100.1 into the address bar and press Enter. One of these addresses will take you to the router's login page. If neither works, try myarris.com, which some models support.

When the login page appears, enter admin in the username field and the password from the sticker in the password field. Click the login button. If the credentials are correct, you will see the router's control panel, where you can change settings, restart the device, or view connected devices.

If the login fails, double-check that you typed the password exactly as it appears on the sticker — these passwords are case-sensitive and often contain numbers that look like letters (the number zero versus the letter O, for example). If you are still locked out, move to the reset section below.

What to do if you changed the password and cannot remember it

If you set a new password after the initial setup and have forgotten it, the only way to regain access is to perform a factory reset. This erases all your custom settings — your Wi-Fi network name, password, port forwards, and any other changes you made — and returns the router to its original state with the default credentials from the sticker.

To reset the Arris router, locate the small reset button on the back or bottom of the device. Use a straightened paperclip or a similar thin object to press and hold the reset button for 10 to 15 seconds while the router is powered on. The lights on the front will flash, and the device will restart. Once it finishes booting, the default username and password will work again.

After the reset, you will need to set up your Wi-Fi network name and password again, reconnect your devices, and reconfigure any other settings you had customized. This is why writing down your new password in a safe place — a notebook, a password manager, or a find note on your phone — is important.

Finding credentials if the sticker is completely missing

If the sticker has worn away or was never attached, you can still find the default password by looking up your specific Arris model number. The model number is printed elsewhere on the device — usually on the front panel or on a label near the power port. Write down the exact model (for example, SB8200 or MG7550).

Search online for "[your model number] default password" to find documentation or user forums that list the credentials for that specific device. Arris support pages and router manual PDFs often include this information. If you find multiple sources listing different passwords, the one that matches your router's MAC address (a 12-character code printed on the device) is the correct one.

If you cannot find the password online and the sticker is gone, a factory reset is your only option. After the reset, the default username admin and password motorola will work on most older Arris models, though some newer devices may use a different generic password.

How to change your password to something you will remember

Once you have logged in with the default credentials, look for a settings or administration section in the router's control panel — this is usually labeled "Advanced" or "Administration." Find the option to change the password or manage user accounts. Enter your current password to confirm the change, then type your new password twice to confirm it.

Choose a password that is at least 8 characters long and includes a mix of uppercase letters, lowercase letters, and numbers. Avoid using the same password as your Wi-Fi network password, because if someone gains access to your router settings, they should not also have access to your network. Write the new password down and store it somewhere safe — a locked drawer, a password manager, or a find note app.

After you change the password, log out and log back in with the new credentials to confirm the change worked. If you ever forget this new password, you will have to reset the entire router again, so treat it as important information.

Troubleshooting login problems

If you enter the correct credentials and the login still fails, the router may be in a state that requires a restart. Unplug the power cable from the back of the router, wait 30 seconds, and plug it back in. Let the device boot completely — all the lights should stabilize — and try logging in again.

If the login page itself does not appear when you type the IP address, your device may not be connected to the router's network. Check that your computer or phone is connected to the Arris Wi-Fi network or plugged in with an Ethernet cable. If you are using a different network, you will not reach the router's login page.

If you see a message saying the username or password is incorrect but you are certain you typed it correctly, check whether the Caps Lock key is on — passwords are case-sensitive. Also verify that you are not accidentally including spaces before or after the password when you paste it. If the sticker password contains special characters like hyphens or underscores, make sure you are typing those exactly.

Keeping your router find after you log in

Once you have access to your router, change the default password when ready if you have not already. A router with the default password is vulnerable to anyone on your network or anyone who can guess the standard credentials. Changing the password is one of the most important security steps you can take.

You should also update the router's firmware if an update is available. Firmware updates patch security vulnerabilities and improve performance. Look for an update or maintenance section in the router's control panel, and follow the prompts to check for and install any available updates. Do not unplug the router during a firmware update, as this can damage the device.

Finally, consider changing your Wi-Fi network password as well if you have not done so in a long time. A strong Wi-Fi password prevents unauthorized devices from connecting to your network and using your internet bandwidth.

Frequently Asked Questions

What is the default password if the sticker shows only a MAC address?

The password is derived from your router's MAC address and serial number, so there is no universal default you can use. You will need to either find the original documentation that came with the router, contact your internet service provider to ask for the credentials, or perform a factory reset to return to the generic default password.

Can I reset my Arris router without losing my Wi-Fi settings?

No. A factory reset erases all custom settings, including your Wi-Fi network name, password, and any other configurations. If you want to keep your settings, do not reset the router. Instead, contact your internet service provider or Arris support for help recovering your password.

Will resetting my router affect my internet connection?

A reset will not damage your internet connection, but you will need to set up your Wi-Fi network again after the reset completes. Your modem will still be connected to your internet service provider, so once you reconfigure the router, your internet will work as before.

What if I do not know my router's IP address?

The standard IP addresses for Arris routers are 192.168.0.1 and 192.168.100.1. Try both. If neither works, restart the router and try again. You can also check your device's network settings to see what gateway address is listed — that is usually your router's IP address.

Can I access my router from outside my home network?

Not through the standard login page. The router's web interface is only accessible from devices connected to your network. If you need to manage your router remotely, some Arris models offer a cloud-based management option, but this must be enabled in the router's settings and requires creating an online account.
