Verizon Router Yellow Light (10 Quick Fixes!)

Verizon Fios has over 6 million internet subscribers and is consistently rated as one of the top 3 internet service providers every year. While Verizon has many great home office internet packages to choose from, they are not without their share of issues. One such issue highly reported by users is the Fios router yellow light error.

Verizon Router Yellow Light

The Verizon router yellow light signifies no internet connection. To fix it, make sure there is an Ethernet cable connection between the router and the Fios ONT box. If the router remains solid yellow, disconnect the Ethernet cable on both ends, wait one minute, and plug it back in.

Many Fios internet users are not aware that there is a Fios ONT box inside or outside the home. As a result, the yellow light signal most often indicates that no Ethernet connection exists between the router and the Fios ONT box.

If your router is already properly connected to the ONT box, simply disconnect and then reconnect the Ethernet cable on both ends after one minute.

Depending on your specific router model, you may encounter one or all of the following Verizon Fios router light signals:

  1. Solid White – Normal operation
  2. Fast Blinking White – Router is booting
  3. Slow Blinking Blue – Pairing mode
  4. Solid Blue – Pairing successful
  5. Steady Green – WiFi is off
  6. Solid Yellow – No internet connection
  7. Solid Red – Hardware/System failure detected
  8. Fast Blinking Red – Overheating
  9. Slow Blinking Red – Pairing failure

Ultimately, a solid white router light indicates normal operation, and that the router is successfully connected to the Verizon Fios network. That’s the goal.

Something to keep in mind is that it can often take between 3 to 5 minutes for the router to connect to the internet. For this reason, if you observe the yellow light signal, allow some time to pass before jumping straight into troubleshooting.

If the issue persists after 5 minutes, I recommend following each of the detailed troubleshooting steps below in the order in which they appear.

Step 1: Inspect The Router And Fios ONT Box Ethernet Connection

In most cases, the Fios ONT box Ethernet connection is to blame.

ONT stands for “Optical Network Terminal” (ONT). The Optical Network Terminal (ONT) converts the signal coming through the fiber into separate signals for TV, voice, and internet.

Notably, the ONT can be installed on either the inside or outside of your home.

Most single-family units, also known as “SFU ONT”, can often be found in the garage, basement, or a closet. In some apartment buildings, there is only one multi-dwelling unit, or “MDU ONT”.

If this is the case for you, you will not have direct access to the MDU ONT in your apartment. Instead, it will likely be in a demarcation room or utility closet within the complex.

Before attempting any other troubleshooting steps, the first thing you should do is make sure there is an Ethernet cable connection running from the Fios ONT box directly to your router.

Fios ONT box connection to router

The router internet speed improvements Verizon has made over recent years has required the change from a coax to Ethernet cable connection.

As mentioned, the Fios router yellow light error is most likely occurring because your router is not connected to the Fios ONT box via an Ethernet cable.

Be sure to plug the Ethernet cable into the corresponding Ethernet port in the back of the Verizon Fios router AND in the Fios ONT box.

In some cases, if your router and ONT box are located near each other, you can personally make this Ethernet connection without any support.

In other cases, if the router and ONT are far apart, you may need to schedule a Verizon Fios technician to come out and make the connection for you.

If your router is already properly connected to the ONT box, simply disconnect the Ethernet cable on both ends. Wait one minute. Then, reconnect the Ethernet cable to the router and the ONT box.

Countless Verizon Fios users have indicated that this is the primary fix that worked for them.

Step 2: Check If There Is A Verizon Service Outage In The Area

Your router can also become disconnected from the internet as a result of a local internet outage.

Go ahead and use your cellphone to visit Down Detector to check if there are any Verizon Fios service outages near you.

You can also search “Verizon Fios outage” and your city on Google or Twitter to see if there are any internet outages in your area.

If there is a local outage, continue to monitor the situation and wait until Verizon has fixed the issue.

In the meantime, if your cellular data plan allows, consider using your cellphone as a WiFi hotspot.

Step 3: Confirm Correct Cable Connections

A yellow light signal can also indicate there is an incorrect router cable connection.

Therefore, it is critical to make sure that you are using the correct cables and that the cables are connected to the correct ports.

To properly connect your Verizon Fios router, follow these two steps:

  1. Plug one end of the power cable into a working wall outlet and the other end into the power port in the back of the router.
  2. Insert one end of the white Ethernet cable into the corresponding Ethernet port on the back of the Fios router. Insert the other end into the correct port on the Fios ONT box.

A solid white light indicates the router is successfully connected to the Fios network.

Step 4: Check For Damaged Or Loose Cables

Correctly connecting the power and Ethernet cables is useless if they are damaged or not firmly connected.

Many users have indicated that damaged or loose cables were to blame for the ‘yellow light on Verizon router’ error.

First, carefully inspect the power and Ethernet cables for any visible damage.

Look at the heads on either end of the cables. Do you notice any visible chips or cracks in the plastic?

Be sure to also straighten out any bends, kinks or indents on any of the cables.

Next, confirm that the connection on BOTH ends of all the cables are secure.

What may seem like an insignificant break in connection can be responsible for your struggling internet. Push all cable ends in firmly.

You should also consider replacing any old Ethernet cables with new ones.

Step 5: Reset The Network

Internet providers assign temporary IP addresses to each of your devices. Oddly enough, these addresses can change at any time!

It’s possible that your router didn’t catch an IP change, resulting in a syncing issue.

To test this, you’ll need to restart the entire network.

To reset the Verizon network, you can perform a standard Verizon router reset or you can try power cycling the router. I recommend first attempting a standard reset. If that doesn’t work, attempt to power cycle the device.

To perform a standard Verizon router reset, locate the red pinhole reset button on the back of the router.

Use a paperclip to press and hold the reset button down for 2 to 4 seconds, and then release. Allow the router at least 5 minutes to boot back up.

IMPORTANT NOTE: Be careful not to hold the reset button for to long as you will lose all of your router settings. If you hold the reset button down for 10 seconds or longer you will perform a factory reset. We have a few more fixes to try before we attempt a factory reset on step 8.

To power cycle the router, unplug the power cable from the adapter or the wall and wait 2 minutes.

During this 2 minute waiting period, also power cycle your network device (i.e your computer, tablet, etc). Finally, plug the power cable back into the Fios Router.

After 3-5 minutes, recheck the Router status light and try to access the internet.

Step 6: Relocate The Router

The location of your router can have a significant impact on your internet connection.

For ideal placement, relocate the router to a central, high-up location away from other devices.

Because the Verizon Fios router sends signals in every direction, placing it low to the ground or tight against a wall can interfere with the signal. This results in decreased coverage!

Do not place router behind TV

Router Location Recommendations:

  • Place the router in an open area
  • Make sure the router is in a central, raised location
  • Try to avoid enclosed areas like the corner of a wall
  • Move other devices as far away from the router as possible
  • Do not place the router behind a TV

For best performance, the Fios router is designed to stand in a vertical, upright position.

Verizon specifically does not recommend wall mounting the Fios router.

By optimizing the router’s location in your home, you dramatically improve your internet connection.

Step 7: Limit The Number Of Connected Devices

If there are too many many devices on your network, your internet can become overloaded.

Too many devices on the network

This can be due to an unwanted neighbor freeloading on your WiFi, or your spouse hogging up all the bandwidth by watching too many high definition movies.

To see how much bandwidth each device is using on your network, you’ll need to sign into your Fios router.

The process for logging into your Verizon router is the same regardless of which model you are using.

Simply open up a browser and go to and then login with the password located on the sticker on the router itself. The username is always “admin“.

Did you identify the guilty party? Or, perhaps you’ve identified an unknown device on your network? Manually remove them!

Step 8: Factory Reset The Router

Yet another fix you can try is performing a factory reset on your Verizon Fios router.

Unlike a standard reset, a factory reset will fully restore your Verizon router to “new”. You will lose all of your custom settings, including your username and password, in the process.

Keep this in mind before proceeding.

To factory reset the router, hold the reset button on the back of the device down for at least 10 seconds.

Now wait approximately 5 minutes for the router to make a connection to the network.

Step 9: Check Your Verizon Account Status

Some users have indicated that the culprit ended up being issues with their Verizon account status.

Go ahead and check your account status by logging into your Verizon account.

Invalid payment methods or errors with your home address and other personal profile settings can result in inactive service.

Confirm your account is up to date and active.

Step 10: Get A New Fios Router

So, you’ve tried each of these troubleshooting steps without any luck?

It is possible that there is a router hardware issue preventing you from connecting to the internet.

As a final measure, you may need to consider heading to the nearest Verizon Fios stores and getting a new Fios router device.


The Verizon router yellow light signifies no internet connection. To fix it, make sure there is an Ethernet cable connection between the router and the Fios ONT box. If the router remains solid yellow, disconnect the Ethernet cable on both ends, wait one minute, and plug it back in.

If this Ethernet cable quick fix doesn’t get your Verizon Fios internet connected, try these additional troubleshooting in order:

  1. Check for local internet outages
  2. Confirm cable connections are correct
  3. Check for damaged or loose cables
  4. Perform a standard reset and power cycle the router
  5. Change the location of your router
  6. Limit the number active devices
  7. Perform a router factory reset
  8. Make sure your Verizon account is active
  9. Get a new Fios router

Unfortunately, these fixes won’t solve the problem for everyone.
