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

By Jonathan Eubanks, Buckeye Telecom  ·  May 20, 2026  ·  9 min read

After 23 years sourcing business internet for Columbus and central Ohio businesses, the two carriers I get asked to compare most often are Spectrum Business and AT&T Business. Both are good companies. Both serve most of Columbus. Both have moments of brilliance and moments where they will quietly cost you thousands of dollars over a 3-year contract. This is an honest comparison from a carrier-neutral advisor — we earn the same residual either way, so I have no financial reason to push one over the other. How we get paid is on our site.

The short answer first

Spectrum Business wins on price for most Columbus addresses, especially for cable internet up to 1 Gbps. They’re fast to install, have decent business-class support, and their fiber-powered cable product is a perfectly viable 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 in the last 3 years, especially along major corridors in Dublin, Westerville, Worthington, and the I-270 ring. Pricing is higher than Spectrum’s cable, but you’re buying a different product.

The right answer depends on what your business actually needs. Below is the framework I use with Columbus clients when they ask.

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.

Speeds and pricing in Columbus (2026): Business cable 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. See the full Ohio pricing spread →.

Where Spectrum shines:

• Single-location small businesses (under ~25 employees) that just need fast internet
• Retail, restaurants, and service businesses where peak usage is modest
• Buildings where dedicated fiber doesn’t exist yet and the construction cost for AT&T or Lumen would be prohibitive
• Buyers who care about price more than guaranteed uptime SLA

What to watch: Asymmetric upload speeds (download is often 10x upload — a problem if you’re running cloud backups or hosting video calls all day). Shared bandwidth means evening / peak-time slowdowns at some addresses. Auto-renewal clauses on 3-year contracts can roll your promo rate to retail at month 13 if you’re not paying attention — we’ve seen monthly bills jump 40–60% silently. Support is good for an ISP but you’re still in a queue.

AT&T Business — what it’s really good at

AT&T’s strength in Columbus is dedicated fiber. Their footprint has grown dramatically in central Ohio in the last 3 years — you’ll find AT&T fiber lit at most commercial buildings along Frantz, Sawmill, Polaris, State Street, and the I-270 corridor. For dedicated internet access (DIA), they’re one of the most reliable providers in the market.

Speeds and pricing in Columbus (2026): 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 have 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’re different products with different SLAs.

Where AT&T shines:

• Mid-market businesses that need guaranteed bandwidth for cloud apps (M365, Salesforce, Zoom, video conferencing all day)
• Multi-location operations with one location running heavy upload (cloud backup, replication, hosted phone trunks)
• Compliance-sensitive industries (healthcare, finance) that need SLA-backed uptime and documentable connectivity
• Any business that has actually felt the pain of "internet’s slow today" 10+ times in the last quarter

What to watch: Install lead times. AT&T DIA installs typically run 4–12 weeks in Columbus — sometimes longer if construction is involved. Don’t sign the AT&T DIA contract assuming you’ll be live in 30 days. Contract terms are firm; early termination fees are real money. Their bundling logic (adding voice, managed router, security) can look like a deal but locks you into multiple services that are individually overpriced.

Side-by-side: who wins for which scenario

$ = cheap, $$$$ = expensive. The right answer is the cheaper carrier that can actually serve your address with the SLA you need. We’ve seen every one of these scenarios go wrong — usually because someone signed the first quote without checking the second.

What to ask before you sign either contract

1. Is this on dedicated fiber, fiber-powered cable, or coax? The carrier rep may not volunteer this. Ask in writing. The product determines your SLA.
2. What is the promotional rate, and what does it roll to at month 13? The promo rate is what they advertise. The retail rate is what you actually pay in year 2 if you don’t renegotiate.
3. What is the early termination fee structure? Some are flat. Some are remaining months times monthly rate. Some are 100% of the remaining contract. Big differences.
4. What’s the install lead time and the construction charge if fiber isn’t at my building? Construction can be $500–$5,000+ as a one-time fee or amortized into a longer term.
5. What’s the SLA for downtime and the credit structure? Cable internet typically has weaker SLA terms than dedicated fiber. Know what you’re buying.
6. Is the equipment included or rented? Modem/router rental can be $15–$30/month per device — $360 over 2 years for a $100 router.
7. What’s the upgrade path? If you need to bump speed in year 2, can you stay on the same contract or do you have to start a new term?

My honest recommendation

If you’re a Columbus business of any size that hasn’t pulled competing quotes in the last 2 years, you’re very likely paying 20–40% more than you should be. The carrier you signed with isn’t the issue. The issue is signing without comparison and not renegotiating at renewal.

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

What we do is the work for you, faster, and with the leverage that comes from sourcing for hundreds of Ohio businesses since 2003 — not just yours. The cost to you is zero out of pocket (carriers pay us a residual whether you go through us or direct), and the typical client saves $4,800–$11,400 per circuit per year versus what they were paying before.
