WASHINGTON — In his most direct effort yet to influence the debate about the Internet’s future, President Obama said on Monday that a free and open Internet was as critical to Americans’ lives as electricity and telephone service and should be regulated like those utilities to protect consumers.

The Federal Communications Commission, Mr. Obama said, needs to adopt the strictest rules possible to prevent broadband companies from blocking or intentionally slowing down legal content and from allowing content providers to pay for a fast lane to reach consumers. That approach, he said, demands thinking about both wired and wireless broadband service as a public utility.

“For almost a century, our law has recognized that companies who connect you to the world have special obligations not to exploit the monopoly they enjoy over access into and out of your home or business,” Mr. Obama, who is traveling in Asia, said in a statement and a video on the White House website. “It is common sense that the same philosophy should guide any service that is based on the transmission of information — whether a phone call or a packet of data.”

The president’s move was widely interpreted as giving political support to Tom Wheeler, the F.C.C. chairman. Mr. Wheeler is close to settling on a plan to protect an open Internet, often known as net neutrality, and Mr. Obama’s statement could push him to adopt a more aggressive approach. Any set of rules needs three votes from the five-member commission, which now has three Democrats and two Republicans.
