Cox vs Frontier Fiber: Cable Incumbent vs Fiber Upstart

Frontier emerged from bankruptcy and went all-in on fiber. Where their rebuilt network overlaps with Cox cable, it is one of the most interesting matchups in US broadband.

Rates as reported for 2026, before promotional discounting. The structural points hold regardless of the figures: Cox cable uploads are asymmetric and capped well below download under DOCSIS 3.1, while Frontier Fiber is symmetric on every tier, and Frontier has added a Fiber 7 Gig tier above the 5 Gig shown here. On the figures themselves, be careful: US broadband pricing is set per address, and we have not re-verified these two rate tables against Cox's and Frontier's own published rates this month. Price your decision off the broadband consumer label each provider is required to show you for your address, not off this table.

Frontier's Post-Bankruptcy Story

Frontier Communications filed for bankruptcy in April 2020 and emerged in May 2021 with a singular strategic mandate: replace their entire DSL and legacy copper network with fiber. The rebuilt Frontier is a different company from the slow-DSL provider that preceded it.

Their rebuild uses XGS-PON throughout, giving them roughly 10 Gbps symmetric infrastructure capable of the 5 Gig and newer 7 Gig plans they now offer. Frontier's 5 Gig plan at about $155/mo is priced competitively against other providers' multi-gig offerings. For homeowners in their footprint, Frontier Fiber is a genuinely compelling fiber option that existed before AT&T Fiber arrived.

Verizon completed its $20B acquisition of Frontier on January 20, 2026. Frontier now operates as "Frontier, a Verizon Company," adding its fiber footprint to Verizon's for a combined reach of roughly 30 million fiber passings across 31 states and DC. Plans, pricing, and the XGS-PON network described here continue to operate under the Frontier brand for now.
