How to Restart or Reset Xfinity Router (XB7–XB10) – Step‑by‑Step Guide

Are you experiencing slow speeds, device connectivity problems, or frequent disconnections with your Xfinity router? Sometimes, all your network needs is a quick refresh. Other times, you might need to start from scratch, like when you’re selling your equipment or can’t solve a persistent issue.

This guide offers a clear, systematic process on how to restart or factory reset your Xfinity router. We’ll cut through the confusion and show you exactly what to do.

Restart vs. Factory Reset: What’s the Difference?

Before you touch your router, it’s crucial to understand the two main options you have. They have very different outcomes.

• Restart (or Reboot): This is like turning your computer off and on again. It clears the device’s temporary memory and resolves minor glitches without erasing any of your personalized settings. Your Wi-Fi network name, password, and other configurations will remain intact.
• Factory Reset: This is a more drastic measure. It completely erases all your custom settings and returns the router to its original, out-of-the-box condition. Your Wi-Fi network name, password, security settings, and any port forwarding rules will be deleted.

How to Restart Your Xfinity Router (Reboot)

A restart is your first line of defense for most common internet problems. It’s quick, easy, and non-destructive. If you notice slowdowns or instability, a quick restart often resolves minor issues; routine scheduled restarts aren’t required for most users.

Method 1: Manual Power Cycle (The Easiest Way)

1. Unplug the power cord from the back of your Xfinity Gateway.
2. Wait for at least one full minute. This allows the internal components to fully power down.
3. Plug the power cord back in.
4. Wait for the router to boot back up. The lights on the front will blink and change. On modern xFi gateways (XB7/XB8/XB9/XB10), you’re ready when the single front light is solid white.

Method 2: Using the Xfinity App

You can also restart your router remotely using the Xfinity app on your smartphone.

1. Sign in to the Xfinity app using your Xfinity ID and password.
2. Tap WiFi > View WiFi equipment.
3. Select your Gateway.
4. Tap Restart. You may also find this under WiFi > Troubleshoot > Restart your Gateway (labels can vary by app version).

Understanding Your Xfinity Router’s Status Lights

The lights on your router can tell you what’s going on. While they vary slightly by model, newer xFi Gateways (XB7, XB8, XB9, XB10) use a single front LED with the following common meanings:

• Solid white: Online and working correctly.
• Blinking white: Starting up or trying to establish a connection.
• Blinking blue: WPS pairing in progress.
• Solid red: No internet connection.
• Amber/orange during registration: Temporary state seen on some models while activating.

Model notes: On XB10 (CGM601TCOM), solid white indicates online, and solid red indicates no internet. If you have an older multi‑LED gateway (XB3–XB6), green may appear during normal operation—refer to your model’s label and multi‑LED legend.

How to Factory Reset Your Xfinity Router

A factory reset should only be used when a restart doesn’t solve your problem, or if you want to completely wipe the device. Remember, this will erase all your settings.

Before You Factory Reset: A Quick Checklist

• Write down your settings: Note your current Wi‑Fi network name (SSID) and password. You will need to set them up again.
• Find the default info: Look for a sticker on your router. It has the default network name and password you’ll need to connect after the reset.
• Backup custom rules: If you have any special configurations like port forwarding or DHCP reservations, make a note of them.

Method 1: Using the Physical Reset Button

This method works for current xFi gateways including XB7, XB8, XB9, and XB10.

1. Locate the reset button on your router. It’s usually a small, recessed hole on the back or bottom of the device, often labeled “Reset”.
2. Use an unfolded paperclip or a similar pointed object to press and hold the Reset pinhole for about 30 seconds until all LEDs turn off.
3. Release the button and allow the router to reboot. Typical return‑to‑online time is 10–12 minutes.

Method 2: Using the Router’s Admin Page

1. Connect a computer to your router using an Ethernet cable.
2. Open a web browser and type 10.0.0.1 in the address bar.
3. Enable Admin Tool access in the Xfinity app if prompted. Then sign in at 10.0.0.1 with username admin and the Admin Tool password you created in the app. For accounts that enabled access prior to February 2026, the default password on the device label may still work.
4. Navigate to the administrative section (often Troubleshooting, Administration, or Utilities).
5. Choose Reset/Restore Gateway or Factory Reset, then confirm.

If You Can’t Access 10.0.0.1 (Bridge Mode/Direct Connect)

If your gateway is in Bridge mode or behind another router, connect a computer directly to the gateway via Ethernet and set your computer to obtain an IP automatically. Then browse to 10.0.0.1. If you still can’t reach it, use the Xfinity app to restart or perform a pinhole factory reset.

What to Do After a Factory Reset

Once your router has finished its factory reset, your old network is gone. You’ll need to set it up again.

• Use the default network name (SSID) and password from the sticker on your router to connect a device.
• Once connected, log back into the Admin Tool (at 10.0.0.1) and change the Wi‑Fi name and password to something secure and memorable.
• Reconnect all of your devices (laptops, phones, smart TVs, etc.) to your new Wi‑Fi network using the new credentials.
• Re‑apply any custom settings like port forwarding rules that you noted down earlier.
• Run a speed test to confirm your connection is working as expected.
