The Welsh Affairs Select Committee has launched an inquiry into the quality of broadband coverage in the principality.
Concerns have been raised that Wales is lagging behind the rest of the UK in terms of broadband deployment, and the committee will assess the extent to which this is true.
"Increasingly, reliable internet access is seen as a driver of economic performance and vital for business, education and people living alone or in isolated areas," a statement read.
"There is, however, some concern that Wales is being left behind other parts of the UK and beyond in the digital revolution."
The select committee said there had been reports of "serious difficulties" experienced by some people living in rural areas in gaining access to broadband services.
Last year, the Welsh Assembly announced plans to deliver 30Mb broadband to all Welsh businesses by 2016, and households by 2020.
