it would work when I was at home and in my college location, but when I would go to Galway, Dublin or somewhere where I wouldn’t usually be it wouldn’t work. But now it dosn’t work at all even when I’m at home or at college.
By the way - are you sure that when you're at home or in college that you're not using wifi - so that if that's no longer working then it's probably because wifi is switched off?
Many people confuse wifi with a carrier data internet connection and don't distinguish between the two.
Hope this helps.
