Cable internet is likely the fastest available alternative for most households here, with fixed wireless from T-Mobile or Verizon as a potential second option.

Fiber internet is available from 2 providers (Optimum, AT&T Internet), with 45% fiber coverage — below the national average of 57%. Fiber delivers symmetrical upload and download speeds — a key advantage for households with multiple remote workers, video conference participants, or content creators who upload large files. Nationally, fiber represents the fastest-growing broadband technology segment, expanding at roughly 8 percentage points of coverage per year. Optimum provides the primary cable broadband alternative with 45% coverage — below-average cable infrastructure for a U.S. market of 72%. Cable internet uses DOCSIS 3.1 technology to deliver download speeds of 100 Mbps to 1.2 Gbps, though upload speeds (typically 10-35 Mbps) lag behind fiber's symmetrical performance. For households that do not require heavy upstream bandwidth, cable plans often offer competitive pricing to fiber. Fixed wireless internet — including 5G home internet services — is available from T-Mobile and AT&T Internet, reaching 52% of addresses (well above the national fixed wireless average of 32%). Fixed wireless offers a no-installation alternative that is increasingly competitive with cable for everyday internet use, with speeds typically ranging from 50-300 Mbps download. Unlike satellite, fixed wireless delivers lower latency (20-40 ms), making it viable for video conferencing and gaming. Satellite internet (Starlink, Viasat, HughesNet) reaches addresses that wired broadband can't. Starlink's low-Earth-orbit (LEO) technology delivers 20-60 ms latency — a major improvement over geostationary services at 600+ ms — making it a practical choice for rural households without fixed-line options.

Residents of ZIP code 45750 can choose from plans starting at $45/mo (Optimum 300 Mbps Fiber Internet, 365 Mbps download) up to 1.2 Gbps (Optimum 1 Gig Fiber Internet at $65/mo).

Ohio received $794 million in federal BEAD funding. The Ohio BroadbandOhio is currently in the challenge phase, which means providers and communities can dispute the FCC broadband maps that determine which locations qualify for funding — a critical step before deployment grants are awarded. The Affordable Connectivity Program (ACP) previously provided up to $30/month subsidies for eligible households, though federal funding expired in 2024. Some providers continue offering voluntary low-income discounts.

Market data is based on the FCC Broadband Data Collection (June 2025). Actual coverage and plan availability may vary by specific address within ZIP code 45750.
