In February 2010, Comcast began to re-brand its consumer triple play service offerings under the name Xfinity; Comcast Digital Cable was renamed "Xfinity TV", Comcast Digital Voice became "Xfinity Voice", and Comcast High-Speed Internet became "Xfinity Internet". The re-branding and an associated promotional campaign were scheduled to coincide with the 2010 Winter Olympics.{{cite news |url= http://www.boston.com/business/technology/articles/2010/02/13/comcast_enters_rebranding_territory/ |title= Comcast enters rebranding territory |author=Bray, Hiawatha |newspaper=The Boston Globe |date= February 13, 2010}}{{cite web |last=Fernandez |first=Bob |url=http://www.philly.com/philly/business/technology/20100203_Comcast_4Q_profit_up_on_revenue_boost__tax_gain.html |title=Comcast unveils new brand name and logo |work=The Philadelphia Inquirer |date=February 3, 2010 |access-date=March 15, 2010 |archive-url=https://web.archive.org/web/20100411070805/http://www.philly.com/philly/business/technology/20100203_Comcast_4Q_profit_up_on_revenue_boost__tax_gain.html |archive-date=April 11, 2010 }}

In 2011, Comcast launched its "Internet Essentials" program, which offers low-cost internet service to families with children who qualify for free or reduced price school lunches.

At the 2017 Consumer Electronics Show, Comcast unveiled a new software platform for its Arris 1682G and Cisco 3941T/3939 modems, which would offer a redesigned configuration interface, support for remote setup and management via an Xfinity mobile app, and enabling integration of supported smart home devices with other Xfinity platforms such as Xfinity TV. The new platform launched under the brand xFi in May 2017. Comcast also unveiled the xFi Advanced Gateway, a new router designed to facilitate faster Wi-Fi speeds, including support for 802.11ac Wave 2, as well as internal support for Bluetooth Low Energy, Thread, and Zigbee for finer integration with Internet of things devices, and support for an accompanying line of Wi-Fi extenders (manufactured by Plume).{{Cite news|url=https://www.engadget.com/2017/12/06/comcast-xfi-advanced-gateway-available/|title=Comcast's xFi Advanced Gateway modem is now available nationwide|work=Engadget|access-date=May 23, 2018|language=en-US}}{{Cite news|url=https://www.theverge.com/circuitbreaker/2017/5/8/15578424/comcast-xfi-app-router-announce|title=Comcast is trying to get in on the mesh router hype|work=The Verge|access-date=May 23, 2018}}{{Cite news|url=https://www.cnet.com/news/comcast-launches-xfinity-xfi/|title=Comcast launches Xfinity xFi, turning gateways into Wi-Fi systems|date=May 7, 2017|work=CNET|access-date=May 23, 2018|language=en}}{{Cite news|url=https://www.cnet.com/news/ces-2017-watch-out-wi-fi-systems-comcast-is-transforming-its-xfinity-gateway-to-a-smart-digital-home/|title=Watch out, Wi-Fi systems!

Comcast operates a network of public Wi-Fi hotspots for Xfinity internet subscribers known as Xfinity WiFi, which consists of a mixture of hotspots installed in public locations and businesses, and those generated by supported Xfinity home gateways on an opt-out basis. Users on the "Performance" tier or higher receive unlimited usage of these hotspots after signing in with their Xfinity Account. By default, all dual-band Xfinity home gateways operate both a private network, and a public network with the SSID "xfinitywifi". To conserve bandwidth, these hotspots are capped at 5 simultaneous users. Customers can opt out of providing Xfinity WiFi through either the Comcast website, or by installing a third-party router.{{cite web|title=Report: Comcast's public Xfinity WiFi program actually costs you money|url=https://www.extremetech.com/computing/185560-new-report-illustrates-how-comcasts-public-xfinity-wifi-program-actually-costs-you-money|website=ExtremeTech|date=July 2014 |access-date=April 6, 2017}}{{cite web|title=To Xfinity WiFi we're all hotspots, but you don't have to be|url=http://www.pcworld.com/article/2363389/to-xfinity-wifi-were-all-hotspots-but-you-dont-have-to-be.html|website=PC World|access-date=April 6, 2017|date=July 2, 2014}}

Comcast has received criticism for this practice, with critics arguing that the company was abusing customer resources (including bandwidth and electricity) to provide services for other customers, as well as concerns regarding security, and liability for actions performed by users while connected to these home hotspots; in 2014, a proposed class action lawsuit was filed in California, citing violations of the Computer Fraud and Abuse Act and similar state laws for these reasons. Comcast defended the service by stating that the public Wi-Fi is firewalled from devices connected to the in-home network, was designed to have minimal bandwidth impact to "support robust usage", and that customers would not be liable for the actions of other users, as abusers can be traced by means of the Xfinity account they used to sign into the network.{{cite web|title=Comcast XFINITY WiFi: Just say no|url=http://www.computerworld.com/article/2476444/mobile-security/mobile-security-comcast-xfinity-wifi-just-say-no.html|website=Computerworld|access-date=April 6, 2017|date=June 28, 2014}}{{cite web|title=Comcast sued by customers for turning routers into public hotspots|url=https://arstechnica.com/tech-policy/2014/12/comcast-sued-by-customers-for-turning-routers-into-public-hotspots/|website=Ars Technica|date=December 9, 2014 |access-date=April 6, 2017}} The lawsuit was taken to arbitration.{{cite web|title=It's Totally Possible That Your Router Is Broadcasting Public Wi-Fi Right Now|url=http://www.slate.com/blogs/future_tense/2016/01/28/juniper_research_1_in_3_home_routers_will_also_produce_public_wifi_hotspots.html|website=Slate|access-date=April 6, 2017|date=January 28, 2016}}

Initially, Comcast had a policy of terminating broadband customers who use "excessive bandwidth", a term the company refused to define in its terms of service, which once said only that a customer's use should not "represent (in the sole judgment of Comcast) an overly large burden on the network".[http://www.comcast.net/terms/use/ Comcast, "Comcast High-Speed Internet Acceptable Use Policy"].

In 2010, Netflix signed an agreement with Level 3 Communications to carry its data.

At the start of 2012, Comcast stood as the United States' third-largest residential line provider,Leichtman Research Group, [http://www.leichtmanresearch.com/research/notes04_2012.pdf "Research Notes,"] First Quarter 2012, pg. 5. The company first gained status as the USA's third largest phone company in 2009. See: [http://www.dslreports.com/shownews/Comcast-Now-Third-Largest-Phone-Company-101317 Comcast Now Third Largest Phone Company], DSLreports.com, March 11, 2009. supplying 9.34 million residential lines.

Xfinity Voice allows communication over the internet using VoIP, but uses a private network instead of a public IP address, which allows Comcast to prioritize voice data during heavy traffic. In technical terms, on Comcast's Hybrid Fiber Coaxial network, calls are placed into individual Unsolicited Grant Service flows, based on DOCSIS 1.1 Quality of service standards. For the customer, this has the benefit of preventing network congestion from interfering with call quality. Other, non-Comcast VoIP services on Comcast's network must use the lower priority public IP addresses. This separation of traffic into separate flows, or Smart pipe, has been criticised as a violation of net neutrality, whereby all data traffic should be treated equally—dumb pipe.{{cite web|url=http://www.multichannel.com/internet-video/smart-pipes-dumb-pipes-and-qos/129650|title=Smart Pipes, Dumb Pipes and QoS|publisher=MultiChannel|author= Leslie Ellis|date=February 17, 2006|access-date=March 8, 2014}} The practice was questioned by the FCC in 2009.{{cite web|url=http://gigaom.com/2009/01/19/fcc-asks-if-comcast-slows-rivals-voip-traffic/|title=FCC Asks if Comcast Slows Rivals' VoIP Traffic|author=Stacey Higginbotham|work=Gigaom |date=January 19, 2009|access-date=March 7, 2014}} In their response, Comcast stated that services that use telecommunications are not necessarily telecommunications services, and said that the FCC's designation of Comcast Digital Voice as an information service exempted it from telecommunications service regulations on traditional landline. Comcast also said that because Comcast Voice was a separate service, it was unfair to directly compare the data for Comcast Voice with the data for other VoIP services.{{cite web|url=http://downloads.comcast.net/docs/january-30-2009-comcast-fcc-response.pdf |title=In the Matter of Formal Complaint of Free Press and Public Knowledge Against Comcast Corporation for Secretly Degrading Peer-to-Peer Applications, File No. EB-08-IH-1518|publisher=Comcast|author=Kathryn A.

Because telephone services over VoIP are not automatically tied to a physical address, Xfinity Voice utilizes E911 to help 911 emergency service operators to automatically locate the source of the 911 call.{{cite web|url=http://www.prnewswire.com/news-releases/comcast-launches-comcast-digital-voicer-phone-service-in-santa-barbara-county-61850297.html|title=Comcast Launches Comcast Digital Voice(R) Phone Service in Santa Barbara County|publisher=PR Newswire|author=Comcast Corp.|access-date=March 11, 2014}} Voice calls are delivered as a digital stream over the Comcast network, signal is converted to analog plain old telephone service lines at the cable modem, which outputs on standard physical analog style RJ-11 ports.

Due to retransmission fees becoming more expensive every year, broadcasters pay more expensive substantial fees for retransmitting broadcast television.

In March 2011, Comcast created an indirect sales channel called the Solution Provider Program, a comprehensive indirect channel program that enables telecommunications consultants and system integrators to sell Comcast's services such as Business Class Internet, Voice, and high-capacity Ethernet services to small and mid-market businesses. The program offers recurring commissions for sales partners based on monthly revenue, and Comcast will provide, install, manage and bill for these services. For the initial launch of the Solutions Provider Program, Comcast enlisted three national master representatives—Telarus, based in Salt Lake City, Utah; Intelisys, based in Petaluma, California; and Telecom Brokerage Inc (TBI), based in Chicago. Sub-agent sales partners must work with one of these three partners in the early stages of the program.{{cite news|last=Henderson|first=Khali|title=Comcast Launches Agent Program |url=http://www.channelpartnersonline.com/news/2011/03/comcast-launches-agent-program.aspx|access-date=March 14, 2011|newspaper=Channel Partners|date=March 14, 2011}}

In 2023, Comcast began to market all Xfinity broadband services as the "Xfinity 10G Network", in relation to its recent introduction of 10-gigabit fiber service for business customers. In 2024, the National Advertising Division of the Better Business Bureau (BBB) ruled that Comcast's marketing of its broadband service as the "Xfinity 10G Network" was misleading, as "10G" could be insinuated as referring to 10 gigabit service. This service is not available to all households or multifamily buildings as it requires installation of a fiber optic local loop, as DOCSIS isn't capable of 10 gigabit end-user speeds.{{Cite web |last=Brodkin |first=Jon |date=October 16, 2023 |title=Comcast resists call to stop its misleading "10G Network" claims |url=https://arstechnica.com/tech-policy/2023/10/comcast-should-stop-advertising-slower-speeds-as-10g-industry-group-says/ |access-date=October 16, 2023 |website=Ars Technica |language=en-us}} In January 2024, Comcast agreed to stop using the "Xfinity 10G Network" branding in this manner.{{Cite web |last=Brodkin |first=Jon |date=January 31, 2024 |title=Comcast reluctantly agrees to stop its misleading "10G Network" claims |url=https://arstechnica.com/tech-policy/2024/01/comcast-to-stop-calling-entire-network-10g-as-name-is-ruled-misleading/ |access-date=January 31, 2024 |website=Ars Technica |language=en-us}}
