I have 2 WiSM in the branch office and 1 4404 working as Anchor in a DMZ all with the 6.0.188 version. In this moment just 1 AP 1242 is working, in a testing environment with 2 SSID:
1. internal WLAN with WPA+WPA2 802.1x with certificates
2. Open guestnet in a EoIP tunnel
Internal users working correctly, but when other clients start to connect to the guest network, clients connected to the internal network are disconnected.
Do you know some way to assign to the ssid a priority or what can I do to mitigate this problem,
