How can I tell if a client is connected with 5ghz or 2.4ghz and when they roam between them?

Turn logging on (either on the AP or ZD) and you'll see entries like this when a client connects:

Nov 20 05:53:01 RuckusAP daemon.info hostapd: wlan0: STA 5c:96:9d:73:59:9f IEEE 802.11: associated
Nov 20 05:53:01 RuckusAP daemon.info hostapd: wlan0: STA 5c:96:9d:73:59:9f WPA: pairwise key handshake

the wlan0 in this case is my 2.4 radio - if it were wlan8 it would be my 5Ghz

I also see in my ZD's dashboard log entries, something like:

2013/11/21 07:54:11 Low guest AP[AP-14194] radio [11a/n] detects User[guest] in WLAN[P-Net] roams from AP[AP-14194]

2013/11/21 07:54:11 Low guest AP[AP-14194] radio [11g/n] detects User[guest] in WLAN[P-Net] roams out to AP[AP-14194]

I don't see that in my dashboard, I see this:

2013/11/26 10:48:55 Low User[mac address] joins WLAN[GuestWLAN] from AP[RuckusAP1]
2013/11/26 10:48:03 Low User[mac address] joins WLAN[WLAN] from AP[RuckusAP2]

This should help.

I think you replied to the wrong thread.
