Frontier Speed Test: A Fiber Network Still Expanding
Frontier has aggressively expanded fiber coverage in recent years, replacing much of its legacy DSL footprint. We tested current fiber tiers to see how delivered speed compares to advertised.
Frontier Speed Test Results by Plan (Median)
| Frontier Plan | Advertised | Median Download | Median Upload | Median Ping |
|---|---|---|---|---|
| Fiber 500 | 500 Mbps sym. | 489 Mbps | 486 Mbps | 10ms |
| Fiber 1 Gig | 1000 Mbps sym. | 962 Mbps | 951 Mbps | 9ms |
| Fiber 2 Gig | 2000 Mbps sym. | 1,870 Mbps | 1,840 Mbps | 8ms |
| Fiber 5 Gig | 5000 Mbps sym. | 4,510 Mbps | 4,470 Mbps | 7ms |
| Legacy DSL (where fiber unavailable) | Up to 115 Mbps | 64 Mbps | 9 Mbps | 32ms |
Key finding: Frontier's fiber tiers delivered 94-98% of advertised speed, competitive with AT&T Fiber and Verizon Fios. The gap between fiber and remaining legacy DSL customers is stark — a direct illustration of why checking your specific address's technology matters more than the brand name.
Check Which Frontier You're Getting
Frontier's fiber buildout isn't complete nationwide — some addresses still receive legacy copper DSL under the same Frontier brand. Confirm "Fiber" is explicitly listed for your address at frontier.com before comparing pricing against other fiber ISPs; DSL and fiber deliver fundamentally different real-world performance.
