Internet Providers in Illinois

Internet availability in Illinois reflects the state's geography. Major cities have multiple fiber and cable providers competing on speed and price. Suburban areas typically have 2-4 options including national carriers. Rural IL households often rely on fixed wireless, satellite, or DSL — though Starlink and 5G home have dramatically improved rural options since 2023. Statewide, fiber availability sits at 14%, with new deployments adding coverage every quarter.

The skyscraper, nuclear reactor, zipper, TV remote, and cell phone are all innovations that come out of Illinois, so it's no wonder that this midwestern state is also home to 167 internet providers, offering an average download speed of 103.41 Mbps. All those providers and megabits translate to sky-high speeds for decent prices in the Prairie State. Illinois is the 29th state in the country for fiber internet because of its 14 percent fiber coverage, and it ranks 10th for its 94 percent DSL coverage and 15th for its 93 percent cable coverage. All that means is that Illinois has got what you need when it comes to speed, whether that's a race at the Chicagoland Speedway or an ultra-fast internet plan.

Fiber is the fastest internet technology in Illinois, with multi-gigabit residential plans available in select markets. Louisville leads the state on raw advertised speed. Cable plans typically top out at 1.2 Gbps download. 5G Home Internet from T-Mobile and Verizon delivers 100-300 Mbps with no install. For raw speed, look for fiber from AT&T, Frontier, Verizon Fios, Google Fiber, or your local fiber co-op depending on which carrier serves your city.

Rural Illinois has historically been under-served, but 2026 brings more options than ever. **Starlink** offers 100-250 Mbps satellite anywhere with a clear sky view — install yourself in 30 minutes. **T-Mobile and Verizon 5G Home** require a strong cell signal but no contracts or installer visits. **Local WISPs** (wireless ISPs) cover specific IL counties with fixed-wireless point-to-point service. Federal RDOF and BEAD funds are also bringing fiber to previously unreached parts of Illinois through 2026-2028.

Illinois businesses have access to enterprise fiber from AT&T Business, Lumen, Spectrum Business, Comcast Business, and regional fiber providers. Dedicated Internet Access (DIA) circuits with SLAs start around $300/mo for symmetrical 100 Mbps. SD-WAN and SASE solutions are widely deployed across IL commercial real estate. For small businesses and home offices, business-class cable and fiber from the consumer providers on this page typically meet the need at a 30-50% price premium over residential.
