Internet providers in Illinois
UPDATED JULY 2026 · BUILT FROM FCC BROADBAND DATA
“Every option at your address — one search, one call.”Illinois has 106 internet providers reporting residential service across 1,397 zip codes (cable data pending an FCC file refresh). Fiber now reaches 99% of Illinois zips, cable 0%, and 5G home internet 100% — and because availability changes street by street, the provider list two blocks over can look completely different from yours.
Fiber in Illinois is led by Mediacom Xtream, reported in 418 zips, with Conxxus the next-widest fiber network. T-Mobile leads Illinois on 5G home internet availability. Roughly 99% of Illinois zips (1,385) have two or more of these competing at the same address — that overlap is where the real pricing leverage lives, and it is exactly what we help you use on the phone.

Satellite service — Starlink, Viasat, and Hughesnet — covers virtually every Illinois address, which matters in the 1% of zips fiber hasn't reached yet. We'll be straight with you on the phone about when satellite makes sense and when a 5G or wired option beats it on both speed and price.
