WASHINGTON — The Federal Communications Commission is preparing a full repeal of net neutrality rules that require broadband providers to give consumers equal access to all content on the internet, putting more power in the hands of those companies to dictate people’s online experiences.

Ajit Pai, the chairman of the F.C.C., plans to reveal a sweeping proposal to scrap the net neutrality rules on Tuesday, according to two people familiar with the plan, who spoke on the condition of anonymity because the details are not public. The rules, created during the Obama administration, prohibit broadband providers from blocking, slowing down or charging more for the delivery of certain internet content. The proposal will be presented in a December meeting of F.C.C. commissioners and is expected to pass in a 3-to-2 vote along party lines.

A rollback of net neutrality regulations would represent a significant victory for broadband and telecom companies like AT&T and Comcast and would amount to a strike against consumers. When the rules were passed in 2015, they underlined the importance of high-speed internet to the lives of Americans and the need to more strongly regulate the communications service like a utility, as essential as electricity and the telephone.
