The average monthly internet bill in Connecticut is $65.37, about 13% below the national average of $77.65 per month. Depending on where you live in Connecticut you can connect via DSL internet over phone lines, traditional broadband cable, super-fast fiber optic cable, mobile fixed wireless, or satellite internet. Fiber optic cable is the fastest internet possible and tends to be available in large metropolitan areas but some regional providers also offer it.

Connecticut has 19 Internet Service Providers (ISPS) including the partial list below. Note that not all plans are available in all parts of the state. Nearly all (99%) Connecticut residents have access to internet connections of 100 Mbps or more.

Speeds are the maximum available at the entry level plan. Where a range is shown, the higher speed may be attached to a more expensive plan. Some providers require contracts. Data allocations can be unlimited or capped. Larger households or heavy users may need unlimited data. Some providers quote plan rates that are part of a promotion. When the promotion ends rates can increase, sometimes dramatically. Plan details can change. Rates excludes additional fees and taxes and may require autopay plus paperless billing:
