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.

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.
