UPDATED JULY 2026 · BUILT FROM FCC BROADBAND DATA
“Every option at your address — one search, one call.”Connecticut has 10 internet providers reporting residential service across 288 zip codes. Fiber now reaches 100% of Connecticut zips, cable 100%, 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 Connecticut is led by Frontier, reported in 288 zips, with GoNetspeed the next-widest fiber network. Xfinity runs the widest cable network here, showing up in 214 zips. For 5G home internet, T-Mobile has the largest reported footprint in Connecticut.
