Verizon Fios Speed Test

Verizon Fios holds a special place in American broadband history. Launched in 2005, it was one of the first large-scale fiber-to-the-home networks in the country — years before Google Fiber or AT&T Fiber existed as consumer products. Two decades later, Fios remains one of the most reliable residential internet services available, consistently ranking at the top of customer satisfaction surveys.

If you are a Fios subscriber running a speed test, the good news is that fiber connections tend to deliver remarkably consistent results. Unlike cable internet where speeds fluctuate with neighborhood usage, your dedicated fiber strand does not share bandwidth with anyone. What you test at 3 PM should be nearly identical to what you test at 9 PM.

The ONT: Your Most Important Piece of Hardware

Every Fios installation includes an Optical Network Terminal (ONT) — usually a beige or white box mounted on an outside wall or inside a utility closet. This device converts the fiber-optic signal into electrical signals your equipment can use. The ONT matters because its model determines what speeds you can actually achieve.

Older ONTs (installed before 2016) may only support output via MoCA/coax, which caps your connection at roughly 100 Mbps regardless of what plan you pay for. If your speed test consistently shows exactly 100 Mbps on a Gigabit plan, this is almost certainly the issue.

Newer ONTs have an Ethernet port that supports Gigabit and beyond. If your ONT is still configured for coax output, call Verizon at 800-837-4966 and ask them to "provision the ONT for Ethernet output." A technician may need to visit to swap the ONT or flip the configuration remotely.

Bringing Your Own Router — Fios Makes It Easy

This is where Fios genuinely shines compared to competitors. Unlike AT&T, which forces you to keep their gateway in the loop, Verizon lets you directly connect your own router to the ONT's Ethernet port. No passthrough modes, no double NAT, no workarounds.

The process is simple:

1. Call Verizon and confirm your ONT is configured for Ethernet output
2. Run a Cat5e or Cat6 cable from the ONT's Ethernet port to your router's WAN port
3. Your router will pick up a public IP address automatically via DHCP
4. Return Verizon's rental router to stop paying the monthly fee

Popular choices among Fios customers include the ASUS RT-AX86U Pro, TP-Link Archer AXE75, and Ubiquiti UniFi Dream Machine. Any router with a Gigabit or multi-gig WAN port will work.

The one caveat: if you have Fios TV, it uses MoCA (multimedia over coax) to deliver the guide and on-demand content. Removing Verizon's router may require a MoCA adapter to maintain TV functionality. Internet-only customers have no such issue.

Verizon's Router: The G3100

If you choose to keep Verizon's equipment, the current model is the Fios Home Router G3100. It is a tri-band Wi-Fi 6 router that performs well for most households. Here is how to access its settings:

Verizon also offers WiFi Extenders (E3200) for whole-home mesh coverage. These connect wirelessly to the G3100 and extend your network to dead spots. They work well enough, though dedicated mesh systems from Eero, Orbi, or UniFi will outperform them in larger homes.

What Numbers to Expect on Your Speed Test

Fios plans are straightforward — and Verizon is one of the few providers that routinely delivers above the advertised speed:

• 300/300 Mbps: Typically tests at 300-320 Mbps both ways on Ethernet
• 500/500 Mbps: Tests around 500-520 Mbps
• 1 Gig (940/880 Mbps): Download usually hits 940 Mbps, upload around 880 Mbps
• 2 Gig: Requires the G3100's 2.5GbE WAN port and a compatible device. On a 2.5GbE adapter, expect ~2,300 Mbps
• Ping: 2-6 ms to NYC/NJ area servers, 10-20 ms nationwide

Over Wi-Fi, expect 400-700 Mbps on Wi-Fi 6 devices sitting near the router, dropping to 150-300 Mbps at range or through multiple walls. This is not a Fios problem — it is a physics problem that affects every router.

No Data Caps — Never Had Them

Verizon Fios has never imposed data caps on residential internet. No soft caps, no deprioritization, no overage fees. This is a genuine differentiator in a market where Xfinity enforces 1.2 TB, Cox enforces 1.25 TB, and AT&T caps DSL plans. Fios customers can stream 4K content across multiple TVs, game online, and run cloud backups without ever checking a usage meter.

Competitors in Fios Territory

Verizon Fios is available across parts of the northeastern and mid-Atlantic US — New York, New Jersey, Pennsylvania, Massachusetts, Virginia, Maryland, Rhode Island, and a few others. In these markets, you will typically find:

• Xfinity is the dominant cable alternative. Higher download speeds are available (up to 2 Gbps), but uploads are much slower, latency is higher, and the 1.2 TB data cap applies. Fios wins on upload speed and consistency.
• Optimum has been rolling out fiber in parts of New York, New Jersey, and Connecticut that overlap with Fios coverage. Their pricing is aggressive, but the network is newer and availability is spotty.
• Spectrum overlaps in parts of New York state. Similar to Xfinity — faster downloads possible, but asymmetric speeds and less reliability during peak hours.
• T-Mobile 5G Home Internet is available in many Fios markets as a wireless alternative. Appealing for its simplicity and price, but cannot match fiber's consistency or latency for demanding users.

Real Questions from Fios Subscribers

Why did my speed drop after a technician visit?

Occasionally, technicians accidentally switch the ONT back to coax output mode after servicing. If your speeds suddenly drop to ~100 Mbps after a service visit, call Verizon and ask them to verify the ONT is still set for Ethernet output.

Is Fios good for gaming?

Fios is excellent for gaming. The combination of low latency (2-6 ms to local servers), zero data caps, and symmetrical speeds makes it one of the best residential connections for competitive gaming available in the US. For best results, use a wired Ethernet connection to your console or PC.

Can I get Fios if my building already has Verizon DSL?

Not necessarily. Verizon largely stopped expanding the Fios footprint around 2010-2015. If your building has copper (DSL) but no fiber, Fios may never come to your address. Check availability at verizon.com/fios or consider T-Mobile Home Internet as an alternative that does not require a wired connection.

What happens during a power outage?

Older ONTs had a battery backup that kept your phone service running during outages. Newer ONTs do not include batteries by default. Your internet and TV will go down during a power outage unless you connect the ONT and your router to a UPS (uninterruptible power supply). A small UPS ($40-60) can keep your internet running for 2-4 hours during a blackout.

What is the Verizon Fios support number?

Technical support: 800-837-4966. You can also chat through the My Verizon app, which is often faster than phone support for straightforward issues like speed concerns or account changes.
