The Welsh economy is being damaged by inadequate broadband provision, it has been claimed.
Monmouth MP David Davies, Chair or the Welsh Affairs Committee, called on the UK and Welsh governments to work together to improve access to high-speed internet services.
He said it is impossible to see how businesses and the economy can develop in poorly-connected areas, such as in rural parts of the principality.
"Access to a fast internet connection is essential to businesses and the economy in Wales," Mr Davies stated.
"Both governments have extremely ambitious targets for broadband provision and there is little time left to meet them."
A Wales Office spokesperson said the issue of broadband coverage in Wales is "well known" and one it is seeking to address in collaboration with the Welsh government.
He claimed that the £425 million investment deal agreed recently with BT - which will provide super-fast broadband for 96 per cent of Welsh homes by 2015 - is testament to how Wales' two governments can work together.
Some £205 million in funding is coming from the public sector, with the rest from BT, which is carrying out the required infrastructure work.
The spokesperson noted that Cardiff has been selected to become one of the first super-connected cities with funding of up to £12 million being provided.
Swansea and Newport will also be eligible to bid in the second wave of funding announced earlier this year, he added.
"We have also committed to improving mobile phone coverage in Wales, with the recent Budget allocating £150 million across the UK, which will include the blackspot between Llandudno and Cardiff," the spokesperson said.
"We continue to seek to work in collaboration with the Welsh government on addressing these issues."
