How to Reset Arris TG2472G

Resetting your Arris TG2472G is one of the easiest ways to correct almost all common technical issues that you may experience over the life of your modem. It’s a super handy tool to have in your troubleshooting repertoire and can save you hours on the phone with your provider. Here’s how it’s done:

  1. Plug your modem in to the power supply and wait 2 minutes for it to boot up fully. You’ll know it’s booted fully when the wireless lights come on.
  2. Locate the reset button on the back of the modem. It’ll be on the same side where all the ports are located. Generally reset buttons on this kind of device will just be a tiny hole that may or may not be labeled.
  3. You’ll need a flattened paperclip or pen cartridge to do this next part. Press down and hold the reset button for 30 seconds with your modem still plugged in. You should feel a small dull click when you press in the reset button with your paperclip.
  4. Now wait a few minutes for your modem to reset and reboot itself. You’ll know it’s finished and ready to use when the WiFi lights come back on.

Tip: Still not resetting? Try just holding down for 15 or 20 seconds instead of the full 30. Some firmware versions differ on the number of seconds needed for a reset.

1. No Internet Connection

  • Power Cycle: Turn off the modem, wait for 30 seconds, then turn it back on. This can often resolve connection issues.
  • Check for Service Outages: Contact your internet service provider to see if there’s a reported outage in your area.

2. Weak or Spotty WiFi Signal

  • Reposition the Modem: Place your modem in a central location and elevate it. Avoid placing it near other electronic devices or behind thick walls.
  • Change WiFi Channel: Sometimes, interference from other wireless devices can cause signal issues. Access the modem’s interface and switch to a different WiFi channel.

  • Check for Dust: Accumulated dust can cause overheating. Periodically clean the modem’s vents using a soft brush.

6. Slow Internet Speeds

  • Check for Bandwidth Hogs: Devices streaming 4K video, downloading large files, or running high-bandwidth applications can slow down the network. Limit such activities during peak usage times.
  • Test with Ethernet: Connect a device directly to the modem using an Ethernet cable and run a speed test. If the speeds are normal, the issue may be with your WiFi.
  • Contact Your ISP: If speed issues persist, contact your service provider to check for external issues or to verify if you’re getting the speeds you’re paying for.


  • Keep your modem’s firmware updated. Firmware updates can resolve known issues and improve performance.
  • If you’re regularly experiencing problems, consider a factory reset as a last resort. This will revert all settings to their defaults, and you’ll need to reconfigure your network.

If you’ve tried the above solutions and are still facing issues, it might be time to consult with your service provider or consider replacing your modem. Remember, technology constantly evolves, and sometimes, a new or upgraded device is the best solution.

    I have two Arris modem/routers, TG2472 and TG3452. Can I use one to wirelessly extend the range of the other, attached to a cable ISP?

      Hi Daniel,

      There are a few things you could do with two modems like that, but it’s not likely to work out like you’re asking. Neither of those models has the ability to act as a range extender to enhance your existing wireless signal to reach further in your house. You can set one to bridge mode if you prefer the range and specs of the other. Bridge mode will forward the wifi part of the service to the other modem and turn it off on the main device. The easiest way to get your wifi range extended would be to add a range extender device. They’re relatively pretty inexpensive and very easy to install. You can check out our article on how to extend WiFi range for more information and options that may be more relevant to your situation.

    Hello there! We currently have this router through our local (and unfortunately only 😒) cable company.
    Please forgive me, I am so not tech savvy! I am quite dumb when it comes to anything and everything electronic!! 😔
    Do you have any information you can give me on if I can get into the routers setting and see if there is any child safety or internet control features??
    My reasoning for asking is that I have 3 daughters that have school issued chromebooks and I am having issues with them staying OFF the wifi and internet watching YouTube 😒 I can’t supervise them from the time they come home from school until they leave in the morning for school. So if I could shut off the wifi for they’re specific chromebooks, it would help me out tremendously!!
