Verizon Fios Internet Speed Test — Free Fiber Speed Check

Run a free Verizon Fios speed test to verify the real-world performance of your 100% fiber-optic internet connection. Fios delivers virtually equal upload and download speeds with 99.9% network reliability. This diagnostic tool measures your symmetrical download speed, upload speed, latency (ping), and jitter. Once complete, compare your results against Verizon's official plan speeds. If your results are lower than expected, our guide covers troubleshooting for Wi-Fi Extenders and real-world wired speed benchmarks.

Verizon Fios Plans & Price Lock Guarantee

Verizon Fios offers all-in pricing with no hidden taxes or equipment fees, and includes a Price Lock Guarantee varying from 3 to 5 years depending on the plan. This ensures your base monthly rate won't unexpectedly spike.

*Lowest bundled price assumes enrollment in Auto Pay ($10/mo savings) and the Mobile + Home Discount ($15/mo savings).

Mobile + Home Discount & Perks

If you combine your Fios home internet with a qualifying Verizon postpaid mobile phone plan, you receive a $15/month Mobile + Home Discount on your internet bill.

Additionally, customers on the 1 Gig and 2 Gig plans can receive up to $10/month towards an eligible perk (such as the Disney Bundle, Netflix & Max, YouTube Premium, Apple One, etc.).

Included Routers & Whole-Home Wi-Fi

Verizon does not charge monthly equipment rental fees for their primary router on new plans. A state-of-the-art dual band router is included to provide fast speeds and low latency.

If you upgrade to the 1 Gig or 2 Gig plans, Verizon includes Whole-Home Wi-Fi. This comes with 1 Verizon Wi-Fi Extender to expand your coverage. A professional technician (or the My Verizon app's Health Check tool) will analyze your signal to see if the extender is needed.

The Ultimate Verizon Fios Troubleshooting Guide (Reddit Sourced)

Verizon Fios is generally regarded as the gold standard for home internet in the Northeast, offering 100% fiber-to-the-home (FTTH) with incredibly low latency. However, when things go wrong, diagnosing the issue can be tricky. We've compiled the most advanced, community-verified troubleshooting tips from network engineers and power users on r/Fios to help you fix persistent speed issues.

1. The Hardware: ONTs and Routers (CR1000A / G3100)

Unlike cable companies, Fios uses an Optical Network Terminal (ONT) installed somewhere in your home (often a garage or basement) which converts the fiber optic light into a standard Ethernet connection. You then plug a router into that ONT.

• The CR1000A Upload Bug: If you were recently issued the newest white tower router (the CR1000A), a massive complaint on Reddit is severely crippled upload speeds (e.g., getting 900 Mbps down, but only 100 Mbps up). This is a known firmware issue with Intel NICs handling IPv6 traffic. The Fix: Log into the CR1000A admin panel, navigate to Advanced Settings, and completely disable IPv6. Users report this instantly fixes the upload speed collapse.
• The G3100 Wi-Fi Limits: The older, cylindrical G3100 router is highly stable for wired connections, but its Wi-Fi range is notoriously short. If you have dead zones, do not buy a random extender; you must use the official Fios E3200 extender, which can connect to the G3100 via coaxial cable (MoCA) for a flawless wired backhaul.

2. How to Use Your Own Router (And Drop the Rental Fee)

If you don't have Fios TV service, you have absolutely zero obligation to use the Verizon router. Using your own high-end mesh system (like Eero or Asus ZenWiFi) is highly recommended by the Reddit community to improve Wi-Fi range and avoid Verizon's firmware bugs.

The Easy "Bring Your Own Router" Setup:

1. Locate the Ethernet cable coming out of your Fios ONT.
2. Unplug it from the Verizon router and plug it directly into the WAN port of your personal router.
3. Crucial Step: The Verizon ONT holds onto the DHCP lease of the old router for up to 2 hours. If your new router isn't getting an IP address, you must release the DHCP lease. Replug the Verizon router, log into its admin panel, navigate to Broadband Connection, and click Release DHCP Lease. Immediately unplug the Verizon router and plug yours in.
4. Alternatively, if you can't release the lease, simply unplug the ONT's power cord (and remove the backup battery if it has one) for 5 minutes, then power it back on with your new router connected.

Note for Fios TV Users: If you have Fios TV boxes, they rely on a coaxial connection (MoCA) provided by the Verizon router for guide data and On-Demand features. If you replace the Verizon router, you will need to buy a MoCA adapter (like the GoCoax) to inject internet back into the coaxial lines, which requires advanced networking knowledge.

3. The "Slow After 24 Hours" Problem

A specific issue reported by power users is speeds degrading significantly after the router has been online for a few days, requiring a reboot to fix.

• Disable SON (Self-Organizing Network): Verizon routers use "SON" to combine the 2.4GHz and 5GHz bands under one name and automatically steer devices. Reddit users universally advise turning this OFF. It is notoriously buggy and often forces fast devices onto the slow 2.4GHz band, giving the illusion of a massive speed drop. Log into the router, go to Wi-Fi settings, disable SON, and rename the 5GHz network so you can force your devices to connect to it.

4. The "Speed Test vs. Real World" Discrepancy

If you are paying for the 1 Gig plan, Verizon guarantees speeds to the router, not your laptop.

Wired vs. Wireless Testing: Always perform a baseline speed test by plugging a laptop directly into the router via a Cat6 Ethernet cable. If the wired test shows 940 Mbps but your phone shows 300 Mbps, you need to adjust your Wi-Fi channels because the Fios line itself is perfectly healthy. Do not call a Fios technician for slow Wi-Fi; they will only verify the wired speed at the ONT and charge you a dispatch fee.
