Spectrum vs. AT&T Business Internet in Columbus, Ohio (2026)

The short answer first

Spectrum Business wins on price for most Columbus addresses, especially for cable internet up to 1 Gbps. Installs are fast, support is decent for a large ISP, and their fiber-powered cable product works as a primary connection for most small and mid-market offices.

AT&T Business wins on dedicated fiber (DIA) at 100 Mbps and above - symmetric, SLA-backed, fully managed. Their fiber footprint in central Ohio has expanded significantly over the last three years, especially along Dublin, Westerville, Worthington, and the I-270 ring. Pricing is higher than Spectrum's cable, but it's a different product.

The right answer depends on what your business actually needs. Here is the framework we use with Columbus clients.

Spectrum Business - what it's really good at

Spectrum runs hybrid coax/fiber across nearly all of Columbus and the surrounding suburbs. For SMB and mid-market offices that don't need symmetric upload speeds and aren't hosting servers, their business-class cable internet is usually the best dollar-per-Mbps in the market.

Business cable in Columbus starts around $65-$150/month for 100-300 Mbps, with 1 Gbps tiers running $200-$400/month depending on building and term. Their fiber-powered product is closer to true fiber but still asymmetric and shared-bandwidth by design.

AT&T Business - what it's really good at

AT&T's strength in Columbus is dedicated fiber. Their footprint has grown fast in central Ohio over the last three years - fiber is now lit at most commercial buildings along Frantz, Sawmill, Polaris, State Street, and the I-270 corridor. For dedicated internet access, they're one of the most reliable providers in the market.

DIA pricing typically runs $500-$800/month at 100 Mbps and $1,000-$1,600/month at 1 Gbps on 3-year terms, depending on address. They also offer a fiber-based business product at lower speeds ($60-$150/month) that sits between consumer fiber and full DIA - don't confuse the two, they carry different SLAs.

My honest recommendation

If you're a Columbus business that hasn't pulled competing quotes in the last two years, you're likely paying 20-35% more than you should be. The carrier you signed with isn't the problem. Signing without comparison, and not renegotiating at renewal, is.

You don't need to hire us to do this work. Call AT&T, call Spectrum, call Lumen, and negotiate them against each other yourself. It's tedious but doable.

What we do is the same work, faster, using relationships built sourcing for hundreds of Ohio businesses since 2003 - not just yours. The cost to you is zero out of pocket, since carriers pay us a residual whether you go through us or direct. Typical clients save $4,800-$11,400 per circuit per year versus what they were paying before.
