I have the dubious pleasure of using a Vodafone Wi-Fi hots at the Jolly Hotel at Cagliari. It must be the lousiest hotspot I have ever used.
I am consistently thrown off every few minutes and association attempts fail three times out of four. It makes it bloody hard to do something with the time you have actually bought.
Using that hotspot to get a message through to Telecom Italia Mobile is just about hell. Their site is so lousy and inaccessible it should be a crime.
