Xfinity Availability

Xfinity (a subsidiary of Comcast) is the largest cable company in the United States. Xfinity’s internet availability area covers 40 states, with the widest statewide coverage in California, Florida, and Illinois as of 2021.

Xfinity delivers service predominantly over a Hybrid Fiber-Coaxial (HFC) network, which also maintains a large public Wi-Fi network for Xfinity customers.

Most recently, Comcast expanded eligibility for Internet Essentials to include all federal Pell Grant recipients within its service area. The expansion increases the opportunity for students to stay connected while pursuing degrees at colleges, universities, and technical schools.

Xfinity Plans and Pricing Overview

Best Features: Things to Consider:
  • Contract-free plans
  • Option to bring your own modem
  • Nationwide hotspots
  • Full-service provider (internet, TV, mobile and home phone, and home security)
  • 1.2 TB data cap on most plans
  • Plans and prices vary by location
  • Higher-than-average equipment fee

Xfinity’s internet plans are feature-packed, but it’s difficult to say which plans are offered where. Customers in Philadelphia can see different promotions, plans, and pricing than those in Atlanta or San Jose. This can be a headache for existing customers who are moving, but not enough to switch providers. Xfinity thrives in offering highly flexible plans able to meet the needs of any budget or household usage needs. Xfinity is one of the few major providers offering a free streaming service and device to all its internet customers. This may offer you an opportunity to become a cord-cutter or at least, give cord cutting a trial run.

Plan Connection Type Download Speed Monthly Start Price
Xfinity Internet Cable Up to 1,200 Mbps $19.99 per month
Xfinity X1 TV Fiber Up to 940 Mbps $65 per month

Xfinity typically offers the lowest-priced internet plan where available; it’s often the provider with the fastest download speed since they’re the only to offer cable internet with up to 1,200 Mbps. You can also get fiber internet with the Gigabit Pro plan, though its availability is limited. Those with access can get download and upload speeds up to 2,000 Mbps.

Xfinity is well-known for its internet and proprietary TV platforms, X1 and Xfinity Flex, but they also offer home and mobile phone, and home security, with steep discounts when you bundle with Xfinity internet. Most recently, Comcast introduced its XClass smart TV – which integrates the X1 and Xfinity Flex platforms into a smart TV and includes one year of Peacock Premium at no additional cost. Prices for the XClass TVs start at $298 for 43 inches and $349 for 50 inches.

In the not-too-distant future, Xfinity X1 customers and broadband subscribers using Xfinity Flex – which is Xfinity’s 4K streaming box – will gain access to the Apple TV app. This will also include the Apple TV Plus subscription service. The Apple TV app allows access to Apple TV Plus, as well as the ability for customers to rent more than 100,000 content titles in the iTunes library. The features of this partnership, announced in late October 2020, will be available in the “coming months” according to officials.

Ways to order XFINITY from Comcast:

Xfinity Internet Speed

Comcast originally built coaxial networks for transporting cable television to TV subscribers. Now, Xfinity uses these cables to deliver digital data and internet connections throughout the Comcast coverage area. This is possible thanks to Data Over Cable Service Interface Specification (DOCSIS), a technology that allows these cables to be used to transport high-bandwidth digital data.

In terms of reliability of Xfinity’s internet connections, service in urban areas tends to perform best. Competing with providers like Verizon Fios and AT&T, Xfinity delivers especially well during peak use times — typically 5-9 p.m.when a large percentage of subscribers simultaneously stream high-bandwidth video. Xfinity’s proximity to fiber in urban areas allows the provider to deliver overall stronger service, especially during these high-use periods.

Fiber lines make up the backbone of Xfinity’s network around the country. For Xfinity customers, this means that data only travels on coaxial cables in the “last mile” between the company’s Xfinity’s local fiber lines and individual subscriber residences. This final hop over coaxial cables bottlenecks speed, particularly upload speeds. However, the relatively short hop means speeds offered by Xfinity run faster than more limited technologies like Digital Subscriber Line (DSL). In many cases, the download speeds come close to those offered by pure Fiber to the Home (FTTH) providers.

Technologists at Comcast see 10 gigabit-per-second upload and download internet speeds over cable lines with the next iteration of DOCSIS.
