Bose EX-1280C looses connection with Ipad during periods of inactivity

[con.andrews]

I have a small installation in a pub that includes an EX-1280C passing audio via Dante to a Yamaha XMV8280D amplifier. Control of the processor is via a single ipad running control space remote that connects via the hotel's wifi network

Every morning when the manager comes to open, there is no communication between the Ipad and DSP and only a complete power cycle of the DSP returns things to normal. This also occurs when the Ipad is left idle for prolonged periods (a couple of hours or so). Needless to say this is not a permanent solution, and one that he has lived with for close to 12 months (if not more)

There is a HP smart switch between the DSP and the WAP. The DSP was set up originally with a static IP, the IPad DHCP. In attempt to try and fix this, last week the hotel's IT service provider reserved a static IP address for the Ipad (albeit on a completely different subnet), but when I spoke to the manager this morning, the issue is still present.

DSP: EX-1280C

CSD: v5.4

CSR: v?? (will need to check next visit)

Country: Australia
