Verizon Fios Speed Test

This page helps Verizon Fios users check their internet speeds. Unlike cable providers, Fios uses a 100% Fiber-Optic network (FTTH), delivering significantly lower latency and symmetrical upload speeds.

Whether you have the Fios 300, 500, or 1 Gig plan, this test will confirm if your Optical Network Terminal (ONT) and Router are performing correctly.

How to interpret your Fios speed test result

Fios results look different from cable internet results:

Symmetrical Speed: This is the key. If you have a 300 Mbps plan, you should see ~300 Mbps download AND ~300 Mbps upload. If upload is drastically lower, there may be an issue with your ONT or Ethernet cable.

Latency (Ping): Fiber is incredibly fast. Expect ping times of 2-10ms. Anything over 30ms on Fios is considered high.

Verizon Fios Router: Expected Performance

Hardware Models

CR1000A / CR1000B: Newer "tall" tower router. Supports Wi-Fi 6E (6GHz band). Capable of multi-gig speeds.

G3100: The older white tower router. Supports Wi-Fi 6. Solid for plans up to 1 Gig.

Typical real-world performance

Wired (Ethernet): Should always be ~95-100% of your listed plan speed.

Wi-Fi: On the G3100/CR1000A, standing near the router, expect 400-800 Mbps on 5GHz devices.

Common Causes of Slow Fios Speeds

If your fiber connection feels slow, check these unique Fios issues:

SON (Self-Organizing Network): Verizon routers combine 2.4GHz and 5GHz bands. Sometimes devices get stuck on the slow 2.4GHz band. Separating them in router settings often fixes "slow Wi-Fi".

Old Ethernet Cables: Ensure the cable between your ONT and Router is Cat5e or Cat6. An old Cat5 cable will cap speeds at 100 Mbps.

Verizon Router Login – Default IP & Password

To change your Wi-Fi password or disable SON, access the admin panel. Unlike other ISPs, Verizon creates a unique random password for every router.

Fios Router Login Details Information
Login IP Address 192.168.1.1
Default Username admin
Default Password See Router Sticker (It is NOT "password". It is a random string printed on the back/bottom label)

Steps to Login

  1. Ensure you are connected to your Fios Wi-Fi
  2. Open your browser and type 192.168.1.1
  3. Enter "admin" as the username
  4. Enter the unique password found on the white sticker on your router
  5. Click "Login" to access network settings

Troubleshooting Status Lights (G3100/CR1000A)

Solid White: Normal operation. Connected to internet.

Solid Yellow: No Internet connection. Check cabling to ONT.

Fast Blinking Red: Overheating or WPS failure.

Solid Red: Hardware/System failure. Try a factory reset or contact support.

Wired vs Wi-Fi Testing

To verify if you are getting what you pay for, perform a hardwired test:

Plug a laptop directly into the router's LAN port. If you see full symmetrical speeds (e.g., 900/900 Mbps), your Fios line is perfect, and any slowness is due to Wi-Fi interference.

When to contact Verizon support

Reach out to Verizon support if:

Your router light stays Solid Yellow for >15 minutes after a reboot.

You see a Red "Fail" light on your ONT box.

Your upload speed is consistently <50% of your download speed (indicating a non-symmetrical provisioning error).

Verizon Fios Speed Test FAQs

What does a solid yellow light on my Verizon router mean? A solid yellow light usually indicates 'No Internet'. The router is powered on but not receiving a signal from the ONT. Check your Ethernet cable connection.

Why is my Verizon upload speed so fast? Verizon Fios uses 100% fiber-optic technology, which allows for 'symmetrical' speeds. This means your upload speed is just as fast as your download speed (e.g., 300/300 Mbps).

How do I log into my Verizon Fios G3100 or CR1000A router? Open a browser and go to 192.168.1.1. The default username is usually 'admin' and the password is printed on the sticker on the back/bottom of the router.

What does the 'SON' setting do? SON (Self-Organizing Network) combines your 2.4GHz and 5GHz Wi-Fi into one name. Disabling it allows you to connect specifically to the faster 5GHz band.
