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.
Updated June 2026
Coverage overlap markets: Arizona, California, Nevada, Virginia, Louisiana, Connecticut, Florida (partial). If you are in these states and Frontier Fiber is available, Cox cable is typically also available.

Frontier has also added a Fiber 7 Gig tier above the 5 Gig shown here. Sources: Cox and Frontier published plans, cross-checked against HighSpeedInternet, BroadbandNow, and CableTV.com. Pricing varies by market and promotion.
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.
