BT Openzone used to work fine but now when I'm on my travels it never does. I've tried it in various places (iPod Touch 4th generation).
Sometimes the screen says I'm connected to the other BT customer's router but I still can't go to anything on the net.
Other times it keeps on trying to connect but never does.
It's a pity because BT's many wi fi spots is the best thing about BT Broadband. If I can't get it to work I might as well quit to somewhere better and cheaper.
