Xfinity is one of the biggest cable internet and TV providers in the US and has a monopoly on high-speed internet in many areas of the country. However, 100% fiber internet providers are busy building out their networks in many states, competing head-to-head with cable internet providers such as Xfinity.
Our team of internet experts says Xfinity offers decent service at moderately affordable prices throughout its coverage area, but encourages internet buyers to comparison shop if a fiber alternative is available.
Xfinity vs. Google Fiber: In cities like Salt Lake City, Kansas City, and Atlanta, customers can choose between Xfinity and Google Fiber. Xfinity offers plans that are much cheaper but slower, especially when it comes to upload speeds, but Xfinity offers fully fiber-optic connectivity and has a much better reputation for customer service.
Xfinity vs. CenturyLink: In cities like Denver and Minneapolis, you might be able to choose between Xfinity’s cable internet and fiber internet from CenturyLink. In wide swaths of the country, you can get either Xfinity internet or DSL internet from CenturyLink. If you can get fiber-to-the-home from CenturyLink, you can find plans as inexpensive as $30 per month for 200 Mbps, which is nearly identical to the Xfinity plan for $25 per month. If you can get only DSL, though, we recommend going with Xfinity because you’ll pay less and have much more bandwidth.
Xfinity vs. Verizon Fios: In many cities on the Atlantic coast, Xfinity competes directly with Verizon’s fiber internet. Xfinity’s plans are cheaper and you have more options, but Verizon Fios never requires contracts. With either provider, you can get deals by bundling your home internet bill with mobile phone and live TV service.
Xfinity’s network is available to about a third of US addresses. In the West, it’s most likely to be available in heavily populated areas around Sacramento, San Francisco, Salt Lake City, Denver, and Santa Fe. Further east, you’ll find it in and around Chicago, Minneapolis, Houston, and the Appalachians, plus the states of Vermont, Massachusetts, Maryland, New Jersey, Delaware, and parts of Virginia and Tennessee.
That said, there can be big differences in availability all the way down to the neighborhood level. After checking for providers in your ZIP code, you may have to enter your exact address with the providers in question.
