I'm new to this device but have followed instructions etc and when trying to connect to a free wireless hotspot, my light is green and the signal strength indicates 100%. I seem to have been assigned an IP address but when opening IE, I can't connect to the internet, I thought I would get their home page but I just get the message that it can't connect with the current settings. I'm sure it's something I've missed but even after reading the wireless guide, no luck.
Thanks
