Hello,   We have a few instances of where we have two different Meraki MX routers for the same customer in fairly close proximity (buildings beside each other on a campus) with their own MR AP's behind them. This causes problems in that, because the SSID is the same, sometimes the client will roam from one building to the other and of course not realize that its old IP is no longer valid because the SSID is a match. If it roams to the other MX and doesn't request a new IP then the user has issues as they are connected but without a valid IP on that network.   Normally I would just create a second SSID for the other building, but the issue here is that most of the users are guests authenticating to a walled garden (Open authentication with sign on method "Billing"), and they should be able to use the same credentials in either building without having to register twice. However it looks to me like Meraki does not allow this and instead stores the guest users on a per SSID basis.   I am wondering if anybody has any suggestions as to how this could be resolved?   Thanks! ...
