Wireless on Sligo line

[wolf99]

Hi folks
Recently (ie last fortnight) Ive noticed a wireless network "Free Public WiFi" showing up on sligo-dublin intercities, however Im never able to connect even though it shows good strength signal reception.
The little connecting to network thing goes up and down, then says not connected but still gives the option to disconnect!

If I leave the laptop on, around kilcock/enfield it'll tell me Im connected, but still not able to browse the internet.

Is this some kind of trial, or have others been able to connect on this network?
Ta
