OBi200 with OBiWiFi5G will ONLY work if you have the SSID (wifi username) and password to configure.
This kind of WiFi hot-spot connections will not work. Connection to hotspot or WiFi network requires additional browser login (such as clicking "Accept" for Terms and Conditions) like what you often find at Starbucks, McDonald's, etc, then is not going to work.
Good luck!
