Customer Reviews for Internet Service Providers in Connecticut
Customer Reviews
A Waterbury, CT Customer
Frontier Fiber
September 04, 2025 Frontier is cheap and reliable. My previous provider offered me a quarter of the speed for 10 dollars more than the non promotional rate frontier offered me. With their 1 year promotion the price and performance were a no brainer. Frontier also came with the amazon eero which had previously been interesting to me. Now using the eero, the device and its app is really easy to use and powerful. The main issue i have with frontier is whenever i need customer service it feels like i have to jump through multiple hopes to do anything, i had a problem recently with their referral program and they just gave me the run around for days.
