Yes , we also have issues with SmartZone100 and firmware 184.108.40.206.808.
1. We lost one Smarzone in a cluster configuration, received an RMA but has the same problem. 2. Clients gets an APIPA address, solution reboot the AP 3. We use WePresent screens (wired) and after the upgrade the connectio to the screens is very slow and sometimes clients get disconnected.
We are in contact with Ruckus support and have 3 open cases.
