Its been in there for years.
Go into your access control list under wireless. You can generate/set per Mac address passwords.
I took my dpsk file from my Zone Director and copy and pasted the passwords in to my access list. Result... The dpsk keys work on my Mikrotik wireless. Unplugged the ZD months ago. The performance of the Mikrotik wireless is no where near as good as the Ruckus APs. But if you don't mind the more than 50% drop off in throughput (866 down to 300)... The Mikrotik WAPs only cost $70 in the US
example from a stand alone Access Point.
/interface wireless access-list
add comment=Jayden mac-address=5C:1D:D9:C3:C6:15 private-pre-shared-key=supersecretpasswordexample vlan-mode=no-tag
example from caps-man
add action=accept allow-signal-out-of-range=10s comment=Jayden disabled=no mac-address=5C:1D:D9:C3:C6:15 private-passphrase=\
So its kind of nice because you can actually make up passwords and they can be any length you want.
Also you can make that one password work for one SSID, All SSIDs, A group of access points, etc.
Further... you can go back and add a VLAN tag to bounce a device into another subnet AFTER ITS BEEN ON THE SYSTEM. (in Ruckus its set once you generate the file)
