Currently have a wireless deployment in a building across 3 floors. Have deployed AP/Mobility Groups to enable the use of a different subnet on each floor of the building. I have tested Roaming throughout the building and all appears fine.
However, should I pick up an IP address on the ground floor of the building, I can then roam to the 2nd floor, disconnect my wireless connectivity and re-connect (In theory, ending the roaming connection) I'm then unable to get an IP address at all for that floor of the building.
To resolve the issue, I connect to the WLC on which I was last connected to prior to disconnecting my wireless connection, remove my association and I'm then able to pick up an IP address for the floor on which I'm attempting too connect. Is there a specific piece of configuration I need in place for this, or is this normal behaivour?
WLCs are running Vers 220.127.116.11
Thanks in advance.
