Thanks for sharing. Many years ago I worked on a classroom wifi system for high schools with each room having its own AP. Each client was typically in the range of 4-6 APs and each classroom had 30-40 clients. You can imagine the probe response floods when they would all try to find their own network. :O We added a wired configuration step over USB to make sure all clients were configured to their own AP to reduce the overhead and problems that came with devices wrongly connecting to the AP in the neighboring class. It felt odd to tell the user to first connect over USB to configure the wireless connection but it greatly help reduce errors and improved the customer experience.
