Just a quick update. I have managed to sneak onto someone's WiFi! Ours is down after an almighty electrical storm. I have never heard thunder as loud as this.
Rosa, our villa owner says the LAN diverter has been hit and is all black inside. She's now changed it for a new box but still no internet so it looks like its more serious.
This is Greek time so it might be a while before we get into a position to add pics to the post.
We are now doing what you should do on holiday. Sit round the pool with an ice cream.
