I have an Zone Director 1100 with this Version 220.127.116.11 build 8 (fresh out from the box) and a few AP ZoneFlex 7352. Manage to Approve this model in my zonedirector but have an error saying "Model[zf7352] is not supported for Ethernet port configuration." i been advice to upgrade my zonedirector firmware but when i reach the support website it require a premium support. But would updating my firmware really solve this problem? i really can't pay if it still have the same problem.
