However, as I test WPA-PSK on this AP and clients, I get a strange error. One client will connect, acquire a dhcp address and be fine. The second client will then connect, acquire an address and then a minute or two later, this error pops up on the AP:
DOT11-6-ASSOC: Interface Dot11Radio0, Station sd-ap 0013.ce0d,0e5d Associated Key_MGMT [WPA PSK]
Dot11-6-DISASSOC: Interface Dot11Radio0, Deauthenticating Station (mac address as above) Reason: Previous authentication no longer valid.
And the client seems to lose connection and reconnect and so forth.
