Motorola NVG510 WiFi 4-Port DSL Modem Router Combo for AT&T U-Verse

Resetting your Motorola NVG510 to factory default settings is really easy and can correct most common technical issues that may come up with your device.

1. First, plug in your modem to the power cable and allow it to boot up fully for about 3-5 minutes.
2. Once your modem is fully powered on, locate the reset button on the back. The reset button is usually inside of a tiny hole directly below the power supply port.
3. Press and hold down the reset button for 30 seconds. You’ll likely need a paperclip or other small object to press and hold the button down.
4. After holding it for 30 seconds, release it and allow the modem to reboot for 5 minutes.

Your modem is now reset to factory default settings!

NVG510 status lights
The following chart shows each status light variation and what it means, making diagnosing and troubleshooting technical issues with your NVG510 easier.

Status lights during firmware upgrades
Firmware updates keep your Wi-Fi gateway running smoothly.  During the software installation, you’ll lose internet and phone service.
The lights will function as follows:

• As firmware is being loaded into flash, the lights will operate normally as described above.
• The installation may take a few minutes. During this phase, the Power light will be Solid Green, the Ethernet light will be Solid Green, and the rest of the lights (Wireless to Phone 2) will flash Solid Green one after the other moving from top to bottom and then bottom to top.

The gateway will restart automatically. As the device reboots, the POWER ON light behavior will happen.

Back in 2012, Arris and Motorola merged, so some products will have a Motorola or Arris logo, depending on when they were manufactured. Because most of the products we carry here on ModemGuides.com are refurbished, you can expect to receive either Arris or Motorola branded device in your order. Please note that the devices are exactly the same aside from branding.

This method works on Windows computers and does not require any software to be downloaded. You’ll be using command prompt to find the internal IP address so you can log into your WiFi router or modem router’s settings panel.

1. Click the start menu in the bottom left of your screen.
2. In the search bar in your start menu, type in “cmd.exe” and then click on that program when it appears in the search.
3. When the program opens, you’ll see a black window on your screen with white text.
4. Type into the program “ipconfig“, then hit Enter. Your window should look like the one shown below. The IP address circled below shows where your internal IP address will be on your command prompt window. Now you can move on to accessing your modem or modem router’s settings admin panel.
