ZD 1200 running latest 9.10 firmware.
6 x 7372 AP's connected via Cisco SG300-10 PoE switch.
I have tried different IP's on the same LAN.
I have tried putting the ZD in a DMZ and restricted firewall access to it.
Cyberoam CR100iNG firewall.
Juniper EX4400 (x5 in virtual chassis)
If the ZD is not connected to the customers LAN, it works without issue.
Ping works fine when UI stops responding.
SSH also stops responding when UI fails.
Wired directly to the ZD does not work either once the UI stops responding.
Tried multiple computers and different browsers.
ZD remains not responding for ever until power cycled. I have left the ZD for a over 48 hours in this state.
The AP's stop communicating to the ZD as well. RADUIS authentication also fails.
Yes the UI comes back up when power cycled, but only for 30-60 seconds.
Ruckus already have replaced the ZD once, this is a brand new installation.
Thank you for your prompt response.
