Well it looks like Mackie hosed their network code. Both 3.2.3 and 4.0.2 worked docked. The results were done after upgrading with V4.02. When attempting to hook up wired (Ethernet no Wifi) I now know why we haven't heard from BenO and company.
It doesn't work and you cant blame Apple for that **. After that attempt the wireless connection no longer worked
until I cycled the DL1608. The docked however was functional, the opposite of what others are seeing. When I cycled the DL I was able to reproduce the above mentioned docking problem and once again it was fixed by cycling the DL. Going back to wireless this time worked. Nice job guys !!!!!
P.S. Mackie it would be nice if you also gave the router the name of your device.
**Update: Well I spoke too soon the wired connection works under the wireless icon (really) sort of. So while it lasts by enabling WiFi until the DHCP exchange is completed you can then disable WiFi and you're on the wired connection. Real logical.
However when the connection is broken (disconnected cable) the reconnect doesn't reestablish sync. Once again power cycling the DL gets it back. Not a viable working setup. This is done under V9.3.1 so on to 9.3.2. Stay tuned.
V9.3.2 results. No change one still has to power cycle the DL once the red dot (disconnect indicator) shows up in setup. I did find that changing to another mode (offline may avoid power cycling) since it removes the disconnect indicator and with patience the wireless icon reappears without a disconnect indicator (red dot). You can then reconnect and it will sync YUK!!. Those instructions from Mackie should be quite interesting reading if they ever show up. Further tests. I was too impatient the DL will actually sync after about a minute +. This may be due to my iPad 3, a little long in the tooth and only MF 4 running.
Conclusion the DL1608 may now have a wired Ethernet (no WiFi) connection as I first suspected, you just have to have patience or maybe a faster iPad. 
In case your wondering if other USB to Ethernet dongles work rest assured that the Apple Only patrol is hard at work. Apple or nothing AFAIKT.
I accidentally disconnected the wire and found that at 60% charge it's a no-go. Sound familiar to those that are using the 30 pin connector? Limit is probably more like 90% and that knocks it out of the box.
What a waste of my 4 hrs.
In order to find the failure point in battery charge level I started with 100% and checked about every 5% disconnecting the Cat5e cable. This time it sync'd all the way to battery warning (10%), go figure. Not too consistent. Looking at other Mackie products like Mackie Connect (Freeplay control) it appears that disconnects are the order of the day.
Maybe it's time to heave that Mandolin.
Digging a little deeper I found the reason for no re-sync. My setup is as follows DI-655 router (for DHCP server) to a Netgear 8 port managed switch which connects the iPad and the DL. If I leave the router connected to the switch all is good when reconnecting the DL. Disconnect the router from the switch (no DHCP) and sync fails. My routers leases are 24 hrs. and were by no means expired. So Mackie fix your code since TCP/IP, UDP or Apple have no such handshake requirements AFAIK.
Mackie static IP addresses do not require access to a DHCP server as in your code (MF 4 ). Looks like a little work is in order here.
