Verizon Fios Speed Test: Consistently Near-Perfect Delivery
Verizon Fios has topped FCC Measuring Broadband America's "percent of advertised speed delivered" rankings for fiber ISPs in recent years. We ran our own 60-day analysis to see if that holds up.
Fios Speed Test Results by Plan (Median)
| Fios Plan | Advertised | Median Download | Median Upload | Median Ping |
|---|---|---|---|---|
| Fios 300 | 300 Mbps sym. | 298 Mbps | 297 Mbps | 8ms |
| Fios 500 | 500 Mbps sym. | 496 Mbps | 494 Mbps | 7ms |
| Fios 1 Gig | 940 Mbps sym. | 928 Mbps | 921 Mbps | 6ms |
| Fios 2 Gig | 2300 Mbps sym. | 2,190 Mbps | 2,140 Mbps | 5ms |
| Fios 5 Gig | 5000 Mbps sym. | 4,780 Mbps | 4,690 Mbps | 4ms |
Key finding: Fios delivered 96-99% of advertised speed across every tier — matching AT&T Fiber as the most consistent providers we've tested, and far ahead of the cable-ISP average of 85-91%.
Why Fios Performs So Consistently
Like AT&T Fiber, Verizon Fios runs dedicated optical fiber to each home rather than sharing a coaxial node with neighbors. There's no peak-hour "node congestion" effect the way cable experiences it — our peak-hour (8-10 PM) measurements showed less than 2% deviation from the daytime baseline across all Fios tiers.
How to Run an Accurate Fios Speed Test
Test on a wired connection through the Fios router's ethernet port first. The included router's WiFi is capable but distance and wall interference will show a bigger drop than the wired connection — isolate the two before concluding your Fios service itself is underperforming.
