Knowing your exact Arris modem model is the first step to troubleshooting connection issues, confirming ISP compatibility, or deciding whether it is time for an upgrade. Arris devices, including the popular SURFboard line, use a clear naming system once you know where to look. This guide shows you four simple ways to find your model number, even if you are not tech savvy.
Key Takeaways
- The fastest way to identify your Arris modem is to check the white sticker on the bottom or back of the device for the model number.
- You can also find your model number by logging into the modem admin page at 192.168.100.1, checking the original box, or viewing your ISP account.
- Arris models follow a prefix system: SB for SURFboard cable modems, SBG for gateways, TM and TG for telephony, and DG for ISP-issued gateways.
Method 1: Check the Label on Your Modem
The label on your Arris modem is the most reliable place to find the model number. Every Arris device has a printed sticker with this information.
Step-by-Step Instructions
- Unplug the modem if you want to handle it more easily, but this is not required.
- Flip the modem upside down or turn it around to view the back panel.
- Look for a white or silver sticker with small printed text.
- Find the line labeled Model or Model No. The value next to it is your model number. Examples include SB8200, SBG10, SBG7400AC2, and T25.
- Write the model number down or take a photo with your phone for future reference.
The same sticker also lists the serial number, MAC address, and HFC MAC, which you may need when activating service with your internet provider.
Method 2: Check the Original Box or Documentation
If your modem is mounted, hard to reach, or you do not want to disturb the cables, the original packaging is the next best place to look.
Step-by-Step Instructions
- Locate the box your modem came in. The model number is printed on the front and the side panel in large text.
- If you have the quick start guide or user manual, the model number appears on the cover.
- Check your email inbox for the order confirmation if you bought the modem online. The model number is listed in the item description.
Method 3: Log Into the Modem Admin Page
Arris modems have a built-in status page that displays the model number. This method works even if the modem is offline, as long as your computer or phone is connected to it.
Step-by-Step Instructions
- Connect your computer, tablet, or phone to your home network using Wi-Fi or an Ethernet cable.
- Open any web browser, such as Chrome, Safari, or Edge.
- Type 192.168.100.1 into the address bar and press Enter. For Arris gateways with built-in Wi-Fi, try 192.168.0.1 instead.
- The status page loads automatically for most cable modems. No password is needed to view the model information.
- Look for a section labeled Product Information, Device Information, or Status. Your model number is listed there.
If the page does not load, your device may not be connected to the modem, or the modem may be using a non-default IP address. Try restarting your device and connecting again.
Method 4: Check Your ISP Account or App
If your modem was supplied by your internet provider, the model is listed in your account information.
Step-by-Step Instructions
- Open your ISP mobile app, such as the Xfinity, Spectrum, or Cox app, or log into your provider account on a web browser.
- Navigate to the section labeled My Equipment, Devices, or Internet Equipment.
- The make and model of your rented modem is displayed alongside other account details.
Understanding Arris Model Number Prefixes
Once you have your model number, the letters at the start tell you what type of device you own. This helps when comparing options or shopping for a replacement.
- SB stands for SURFboard. These are cable modems without built-in Wi-Fi. Examples include the SB6183, SB8200, and S33.
- SBG stands for SURFboard Gateway. These combine a modem and a Wi-Fi router in one device. Examples include the SBG10, SBG6900AC, SBG7400AC2, and SBG8300.
- TM and TG indicate telephony modems and gateways with phone service support. Examples include the TM1602A and TG1682G.
- DG and NVG prefixes are typically found on modems and gateways issued by internet service providers.
- T with a number, such as T25, identifies newer DOCSIS 3.1 telephony modems.
A Note on Arris and SURFboard Branding
Arris was acquired by CommScope, and the SURFboard product line later became its own brand. If your modem is labeled SURFboard without the Arris name, it is still part of the same product family covered in this guide. Older devices may carry both the Arris and SURFboard names on the label.
What to Do Once You Know Your Model
With your model number in hand, you can:
- Confirm your modem is on your ISP's approved devices list.
- Check whether your modem supports DOCSIS 3.0 or DOCSIS 3.1, which affects your maximum speed.
- Look up troubleshooting steps for specific issues like blinking lights or dropped connections.
- Decide whether your current modem can handle your internet plan or if it is time for an upgrade.
If you need a replacement, top picks include the SB8200 for most gigabit plans, the S33 for multi-gig service, or the SBG8300 if you want an all-in-one modem and Wi-Fi router.
