Verizon Fios Router Yellow Light: Meaning

In the following paragraphs, we are going to refer to the Verizon Fios Home Router G3100. This router doesn’t have a series of lights like most commercial routers. Instead, it has one circular status LED light at the front. Normally, this light will be solid white. That is a sign that everything works well.

However, seeing a yellow light on our Verizon Fios Home Router G3100 is a sign that the internet connection is down. There are several different reasons for this, and we are going to cover each in the following section. Also, we will offer solutions for each cause.

Verizon Fios Home Router G3100 Yellow Light: Causes and Solutions

Here are some of the most common problems that can cause our internet connection to go down. While we can usually do something to restore our internet connection, sometimes, it is beyond our control. So, let’s see what we can do.

Power Cycle Your Verizon Fios Home Router

If you’ve had any problems with your network before or with any electronic device, you must have heard that you should restart it to get it fixed. Well, this simple solution has helped many users to fix this problem. It is pretty easy, and it doesn’t require any tech knowledge.

  • Turn off the router.
  • Unplug the power cable from the electrical outlet.

Unplug the power cable

  • Leave the router disconnected for 2 minutes.
  • Plug the power cable back into the wall outlet.
  • Turn on the router.
  • Give it some time to boot up properly and stabilize.
  • Check the light.
  • If it’s white, then great. If it’s still yellow, continue with the troubleshooting.

Loose Connectors or Damaged Cables

When you connect your equipment, it is important to pay attention to each connector and cable. Every connector should sit firmly in its place, everything should be connected properly, and the cables must not be damaged.

It won’t take much of your time to check these things. Just make sure to check both ends of each cable. Here is a short checklist:

  • Is there visible damage on any of the cables? Are any of the cables bent abnormally? If yes, try connecting another cable and check the light.
  • Are the cables firmly connected? When you plug an Ethernet cable into the port, you will hear a clicking sound. Also, when you connect the coax cable, make sure it is screwed in tightly.
  • Are the cables properly connected? The cable going from the wall Ethernet port or your ONT should go into the WAN port. Other cables go to the LAN ports. The coaxial cable goes to the coax port.

  • Are the connectors damaged? A damaged connector will get loose easily and will result in yellow light on your Fios router (no internet connection). So, if you notice some damaged connectors, replace the connectors or the entire cable.

How to Properly Install Your Verizon Fios Router

Restart the Verizon ONT and the Router

Most users will try to stay away from the ONT. However, restarting the ONT and the router is something others have tried, and it helped them fix the problem. If you think that you shouldn’t touch it, move to the next step. However, if you decide to try it, here is how to do it.

  • Turn off the Verizon Fios Home Router.
  • Disconnect the ONT from the AC adapter.
  • Disconnect the ONT battery if there is one.
  • Leave them disconnected for 2 minutes.
  • Reconnect the ONT battery back again.
  • Reconnect the ONT and the AC adapter.
  • Give the ONT some time to boot up.
  • Turn on the Verizon Fios Home Router.
  • Give it some time to boot up as well, and check the router light. It should be white now.

Note: Some Fios users have reported they managed to fix the problem by simply unplugging the Ethernet cable from the ONT Data port and re-plugging it. They didn’t have to restart the entire ONT. This is a simpler solution, so you may want to try it before restarting the entire ONT or your entire network. 

Is Verizon Down?

A service outage can be caused by regular maintenance conducted by your ISP. It could also happen when your ISP is experiencing some problems like power outages, network problems, and similar.

You can check whether this is causing the problem through the Verizon Service Outage Information page. Just sign in to your account, and you will see an alert message informing you about the outage.

You can also visit some third-party websites, and see if other Verizon users have reported some problems with their services.

If you verify that this is the reason for the yellow light, then you need to be patient. The problem will likely be fixed very soon. When that happens, the yellow light will magically disappear. There is really nothing else to do in this case.

Is the Router Overheating?

If you have tried the solutions above and you still can’t get rid of the yellow light on your Fios router, overheating may be the problem. This can happen if the ventilation is blocked either by other objects, furniture, or dust in the vents.

If you suspect that overheating is causing the problem, remove the objects around the router or move it into an open space where it will be properly ventilated. Or simply check whether you need to take care of the dust in the vents.

Although this may not fix the problem instantly, it should be fixed after a while.

Reset the Router to Factory Default Settings

If nothing else helps, there’s only one more thing to try before contacting Fios support – you need to reset your Fios router. This might sound scary, especially if you don’t have any technical knowledge, but it’s actually a simple procedure. A much bigger problem is setting up the router all over again after resetting, but even that should not be a huge deal.

If you’re a regular user and don’t have a bunch of custom-made settings, you will just have to change your Wi-Fi network name and password. That should take less than a minute. 

To reset your Fios router, located that tiny red pinhole on the rear panel of your router. Press it using some sharp object and hold until the LED light on the front panel disappears. Release the button and wait for the router to reboot.
