xFi Gateway Won’t Turn On? – (8 Proven Solutions)

If your xFi gateway won’t turn on, don’t panic. We got your back!

The xFi gateway provides fast and reliable internet service from Comcast Xfinity, but sometimes, it doesn’t work properly.

The error often indicates power supply issues, electrical problems, or faulty hardware.

To get your xFi Gateway to turn on, check the power source, cable, and adapter to make sure that everything is connected properly. You also want to perform a power cycle to discharge it fully.

Alright, let’s move on to the solutions. 

8 Proven Solutions for xFi Gateway Won’t Turn On Issue

We listed 8 proven solutions to fix your xFi gateway problem. Some seem obvious, but they work more often than you think. 

1. Plug Your Gateway to a Different Power Outlet

One of the first things you should do is ensure the power outlet your xFi gateway is plugged into is working properly.

Faulty or damaged outlets prevent your devices from getting power. Rule out this possibility early on.

Here’s how:

1. Unplug your gateway from the current power outlet. 
2. Plug it into a different power outlet. 
3. Ensure the outlet is not controlled by a switch or a timer.
4. Wait for a few seconds.
5. See if your device turns on. 

Note: The voltage and power requirements of the new outlet should be compatible with your xFi gateway. Using an outlet with the wrong voltage will damage your device. 

2. Check the Power Adapter

Next, check the power adapter that connects your xFi gateway to the power outlet.

A loose, broken, or defective adapter also causes your device to fail to power on. Ensure the adapter is properly connected and functioning. 

To do this, follow these steps:

1. Unplug your xFi gateway from the power adapter.
2. Inspect the adapter for signs of damage or wear. 
3. Look for burns, cracks, cuts, or frays on the cord or plug. 
4. Ensure the adapter is not wet or exposed to extreme temperatures.
5. If you find any damage, replace it with a new one.
6. If not, plug it back into your gateway. 
7. Wait for a few seconds and see if your device turns on. 

Contact Comcast Xfinity customer service or visit their website to order a new adapter.

3. Make Sure All the Cables Are Connected Securely

Another way to fix an Xfinity gateway that won’t turn on is to ensure all the cables are connected securely to your devices.

Loose, damaged, or disconnected wires cause your gateway to malfunction or fail to turn on. 

Here’s how to ensure all cables are properly connected:

1. Check all the cables that connect your xFi gateway to the following devices:

• Modem 
• Router
• Computer
• Phone
• TV

2. Ensure they are plugged in firmly and correctly. 
3. Inspect the wires for signs of damage or wear.
4. Look for any bends, breaks, kinks, or twists on the cable. 
5. Reconnect any loose wires securely.
6. Replace damaged cables with new ones. 
7. Wait for a few seconds and see if your device turns on. 

Tip: Label or color-code cables for easy identification, making it especially helpful in complex setups with multiple connections. 

4. Use a Surge Protector to Safeguard Your Gateway

Use a surge protector to safeguard your xFi gateway from spikes or power surges.

Sudden increases in voltage caused by power outages, faulty wiring, lightning strikes, and other factors damage or destroy your electronic devices. 

Using a surge protector helps prevent such.

Here’s how to use one:

1. Select a surge protector with enough outlets and joule rating.
2. Unplug all devices from their power sources. 
3. Plug the surge protector into a wall outlet. 
4. Connect the xFi gateway’s power adapter to the surge protector. 
5. Plug other devices into the remaining surge protector outlets. 
6. Power on the surge protector and connected devices. 
7. Check the indicator lights on the surge protector. 

Refer to the surge protector’s user manual to understand its indicators. Remember, surge protectors have a limited lifespan and effectiveness. 

Tip: Regularly check and replace the surge protector if you see signs of wear or if it has protected against a significant surge. 

5. Power Cycle Your Gateway

Power cycling is a proven solution for an xFi gateway that won’t turn on.

A power cycle means turning off and on your device to reset it and clear any glitches or errors.

It also helps fix common issues, including the gateway not turning on. 

To do this, follow these steps:

1. Unplug your xFi gateway from the power outlet.
2. Wait for 10 seconds.
3. Plug your gateway back into the power outlet. 
4. Wait for another 10 seconds.
5. Press and hold the power button on the back of the gateway.
6. Release it after 5 seconds or when you see the lights flash.
7. Wait for your gateway to reboot. 
8. Wait for a few seconds and see if your device turns on.

If power cycling doesn’t solve the problem, check your router and modem or contact your service provider for assistance.  

6. Tighten the Coaxial Cable Connections on Your Gateway

If you still have an xFi gateway not turning on, tighten its coaxial cable connections. The coaxial cable connects your gateway to the cable outlet.

Sometimes, it gets loose or is not screwed in properly, affecting your gateway’s performance and causing the issue. 

Info: The coaxial cable on the xFi gateway is labeled as Cable In or RF In. 

To do this, follow these steps:

1. Locate the coaxial cable on the back of your xFi gateway.
2. Unscrew it and check for signs of damage or wear.
3. If you find cuts, frays, or bends on the cable, replace it with a new one. 
4. If not, screw it back into your gateway securely. 
5. Repeat the same steps for the other end of the cable.
6. See if your gateway turns on.

Tip: Use adequate force to secure the connection to avoid over-tightening, which could damage the connectors.

7. Inspect the Gateway for Signs of Physical Damage

Next, inspect your xFi gateway for signs of physical damage. Physical damage occurs due to accidents, mishandling, or other factors and causes your gateway to malfunction or fail to power on.

Note that it isn’t covered by warranty, and attempting to repair it yourself may cause further damage.

Here’s how to check for any signs of physical damage:

1. Check the exterior of your gateway for burns, cracks, dents, or scratches. 
2. Look for signs of water damage, such as discoloration or rust. 
3. Inspect the ports and connectors for signs of damage or wear. 
4. Check the lights and indicators to see if they’re functioning properly.
5. Ensure your gateway is not wet or exposed to extreme temperatures. 

If you find any sign of physical damage on your xFi gateway, contact Comcast Xfinity customer service or visit their website to request a replacement. 

8. Reset Your xFi Gateway to Factory Settings

If none of the previous solutions work, the last thing you should do is reset your xFi gateway to factory settings. Resetting your gateway restores it to its original state.

This helps fix software issues that prevent your gateway from turning on or working properly. 

Before you do this, you should know that it will also:

• Delete all your WiFi network names and passwords
• Delete your parental controls and device profiles
• Delete your port forwarding and firewall settings
• Delete all your custom DNS
• Delete your xFi Pods settings

So, document or save your current network settings and configurations before the reset. 

To reset your xFi gateway to its factory defaults, follow these steps:

1. Locate the Reset button on the back of your gateway.
2. Press and hold it for 15 seconds using a pin or paper clip. 
3. Release the Reset button when you see the lights flash.
4. Wait for your gateway to reboot.
5. See if it turns on.

After the reset, reconfigure your network settings, such as your WiFi name and password. Then, use the Xfinity app or website to set up your xFi gateway again. 

If the issue persists, contact Xfinity customer service or visit their website for assistance.
