Two new studies have shown that connections in some rural areas are so bad that emails can't be opened.

Website Switcher.ie carried out 27-thousand tests and found that a third of customers were left unable to perform basic online tasks.

The data also suggests that as few as a quarter of households could be receiving speeds of 30Mbps or more, the minimum target set out in the National Broadband Plan.
