A new report on the rollout of high speed broadband here has found progress has been made but a number of significant issues remain.
The assessment by the European Court of Auditors looks at how European funding is being spent on broadband projects here and in four other EU countries.
The study says that through private and public investments, Ireland has significantly increased its fast broadband coverage since 2011 and has plans to increase further this coverage in rural and sub-urban areas.
But it also says that based on past progress and current plans, it is unlikely the 30 Mbps target will be available to all people here by 2020.
However, if the current plans are implemented as intended, Ireland will be better placed to achieve the 2025 targets, it says.
The audit also found weaknesses in Irish plans for infrastructure investments.
It says the €275m in funding allocated by the Government here for the rollout of the National Broadband Plan, including €75m from the European Regional Development Fund, is highly unlikely to be sufficient to bridge the financing gap between private funding and the cost of the scheme.
It also says that with only one bidder, enet, left in the tendering process, the impact on the cost and timing of the broadband deployment remains unclear.
The analysis also found weaknesses in the legal and competitive environment here have resulted in competitive issues.
It says the limitations on the power of the telecoms regulator, Comreg, to enforce its decisions were possibly hindering the scope for effective competition.
In 2010 the EU set three targets for broadband, requiring basic broadband delivery of up to 30 Megabits per second to all Europeans by 2013, fast broadband of over 30 Mbps by 2020 and up to 50% take-up of ultra-fast broadband of over 100Mbps by 2020.
The EU has made some €15bn available to member states in the period 2014-2020 in order to support that objective, including €5.6bn in loans from the European Investment Bank (EIB).
This audit looked at the effectiveness of the action taken by the European Commission, member states and the EIB in realising the 2020 objectives.
Five member states including Ireland, Germany, Hungary, Poland and Italy were all assessed.
The report found that although broadband coverage is improving across the EU, some Europe 2020 targets are unlikely to be achieved.
In a statement, Fine Gael MEP Brian Hayes welcomed the positives in the report about Ireland, but added that outstanding issues remain a worry.
"Ireland is not alone in missing clearly stated targets when it comes to delivering broadband," said Mr Hayes who is member of the Budget Control Committee of the European Parliament.
"Having all communities and citizens connected is vital for Europe to deliver a better way of life and new business, especially in peripheral parts of the EU. Funding from the EU to help Member States deliver on that commitment should be audited and we can all learn from that.
"The essence of the report for Ireland - we must try harder to deliver this key infrastructure."
