Internet access issues between the IAP-103 & FVS336Gv2

First - a couple of questions 1 - how is the Aruba connected to the FVS and does it get it's address using DHCP? 2 - what DHCP lease duration are you running? 3 - are there any other devices in the network that do not connect via the Aruba - are these devices affected when the WiFi fails - if there are none, it might be worth the effort to temporarily connect a laptop directly to the FVS for troubleshooting purposes. If devices directly attached to the FVS do not lose their connection along with the wireless ones, that would suggest that the FVS is not the source of the problem. At a glance, the symptoms suggest that there is an intermittent connectivity issue between the FVS and the Aruba, or that either the FVS or the Aruba may be locking up, which is what led to my suggestion of connecting a device directly to the FVS. What's puzzling me is ... 1 - and I recognize this may simply be how the device reports the symptoms - is that in my experience failure of the DHCP server or loss of connectivity to it, should not prevent a wireless client from associating with an access point (AP) (or joining a WiFi network), they should associate with the AP but not get an ip address, which typically results in an APIPA address (169.254.x.x) 2 - if you can't join the network how can you tell what ip address the Aruba has, and if it is set for DHCP and unable to access the FVS, why is it not reporting an APIPA address?
