Commuters will be able to connect to the internet from July
The first stations to be WiFi enabled include Southfields and Wimbledon Park locally, as well as Oxford Circus, Stratford, Liverpool Street, Leicester Square and King's Cross among 80 London-wide.
Virgin Media's next generation WiFi service will be made available to all Tube passengers for free throughout the summer.
Millions of commuters and visitors to London will be able to get online at Tube stations and find their way around the Capital with up-to-the-minute TfL travel information, access social media while they wait for their next train on the station platform, or browse the web.
Gareth Powell, London Underground's Director of Strategy and Service Development, said: "Our customers will soon be able to connect to the internet for live travel information while they are on the move through stations.
"Bringing a next generation WiFi service to one of the world's oldest underground transport networks is progressing as planned and the forthcoming service is testing well.
'The first stations include some of our busiest and most well-known destinations and we're on-track for a successful launch this summer."
Jon James, Executive Director of Broadband at Virgin Media, said: "In partnership with TfL, we've been working around-the-clock to install and test WiFi on London Underground and are about to connect some iconic and world famous Tube stations with a WiFi service London will be proud of."
Virgin Media and London Underground engineers continue to test and prepare the forthcoming WiFi service, including recent capacity testing at Chancery Lane underground station where hundreds of devices were connected to the station's WiFi service at exactly the same time to reproduce the service experience of a busy Tube train arriving at the station.
