I have a network across two buildings that are quite close to each other. Each building currently has it's own network, and there is a wireless bridge between the two. Each building has it's own internet connection which is plugged into a router. The router has failover set to use the other building's connection if it's internet goes down, as well as to route traffic to servers in the other building when necessary. Each building also has several APs broadcasting the same SSID.
Currently, clients connected to the Wi-Fi at building A need to disconnect and reconnect when they go to building B, as the DHCP lease from building A is no longer valid. Is it possible to have clients roam between sites without doing this?
The routers on each site are Ubiquiti EdgeRouters, and the APs are Unifi AP-Pros. The SSID cannot be changed for various reasons, however there would be no issue on having the clients using NAT to get to the main network at each building (I believe this is how the Cisco Meraki APs deal with this issue)
