Hi Natalie,
So sorry to hear that you've been having trouble connecting to the WiFi in Dublin! You mentioned that you had both internet and phone issues while you're in the city. Would it be an option to buy an Irish SIM card with data so you can use it while you're here? There is a useful thread called '
Mobile Phone use in Ireland' which might be of interest.
You will also find that libraries, hotels, cafe's and pubs offer free WiFi to their customers, and it is also possible to visit one of the Internet Cafe's.
Maybe there is another member of the Community with another tip, and if there is anything else, please don't hesitate to get in touch!
