How much time is left on my WiFi connection

You will have received an email stating the date & time that you purchased the WiFi, and it just runs for one day, one week, one year (whatever the multiples are that you can buy), so you don't really need to know how many hours & minutes you've used up, only the date & time it runs out.

In deed I probably did, But I don't have all my old emails with me or online. And I cant remember when I purchchased the WiFi!

I have just tried it and it worked fine for me, detailing how many days and hours I have left. However, the wifi at this site is good. I have certainly experienced what you describe when connections have been slow. All I can suggest, I'm afraid, is to try it on the next site. If it has run out it will ask you if you want to renew when you try and log on. You can only subscribe on a CC connection in any event, so it does not really matter that much, as you will have to wait until you are on site again to renew.
