I can connect to the hotspot and log in on the browser on the 3DS, but whenever I try to connect on a game it brings up an error message. Even though I'm connected through the browser. I'm maybe trying to do the impossible but can you use the hotspot for games?
Welcome to the forum. I don't know how much bandwidth you need, but the maximum you can get from a BT WiFi hotspot is 3Mbps, and even that may be compromised depending on local conditions. Commercial (BT Openzone) hotspots go to 8Mbps.
