A followup on the now reproducible failure on all three Music Tribe products. XR12, MR12, MR18 all fail if given sufficient time of about 48 hrs. If the typical usage is 4-8 hrs you probably won't experience it although on my MR12 it appeared after 6 hrs. This is done with 4 dynamic mics attached and one control surface a iPad 3 no activity other than screen refresh. Same results if a Android tablet is used. Not likely to be a hardware problem unless it is a design flaw in the MRF24WG0MB module. Since MG is using ucLinux a home-brew Real Time OS and possibly not using the Microchip Software complicates matters. Very little is known about the characteristics of the WiFi capabilities other than a bare bones implementation of 802.11 b/g. RSSI (signal power) is typically running 10dBm below any of my WiFi routers (Netgear, Cisco (Linksys), D-Link)). A packet analysis is required to dig deeper. My recent sink or swim test of about ~160 audience (probably about 100 phones of various makes) cut the time to minutes. This however could be just a overload of traffic in the 2.4 GHz band and was corrected by requesting phones to be set to Airplane mode. :) Lucky me since they complied with the request  >:D. MR12 power needed to be cycled for recovery however.
Getting Mackie and the Tribe confused  :eek:

I have a co-worker who is also running the MR/XR18 and had severe trouble connecting to the onboard wi-fi at an outdoor show where they were very close to a lot of extraneous wireless signal traffic in the vicinity. They were blocked from connecting to the mixer, period. I will retain and use my Apple  Airport Express that I have had in the rack since my DL1608 days. So far, all my testing has been perfect performance. After seeing this message on the Tribe site, I tested my setup by running it overnight.

I would expect that. Normally I use a wired connection to a PC to run the X-Air series and wireless for initial setup. I don't need to be concerned about control disappearing on me. The above mentioned test of ~160 was due to my rearranging my setup (missing the external router at the time) when I was asked to do this gig (3 days prior and no time to add router). What better way to test out suspicions about the 2.4 GHz band. I don't have 100 phones. Normally I run the setup by wire but couldn't due to incorrect info about the setup (cables). When I have a chance I will try to use fixed IP as a workaround to see if it makes a difference (typical Black Box test). Normally the stations (iPad etc.) will start roaming processes once the RSSI gets to -65dBm or lower and that could affect connections. There is literally no access to the embedded module settings other than SSID, IP(fixed), mask, Gateway/DNS and channel. Here's hoping that simplification will bypass logic bugs :).

LeeSteel:
With the camera kit attached to my iPad, should I be able to achieve a wired connection to the XR18? Because right now I can't seem to make that happen. WiFi is spot on. Also, contrary to what some others have posted, the USB to camera kit is not working to charge my iPad either.

WK154:
First let me say that I wouldn't recommend that route. See the convoluted hookup and parts required for the iPad (only tested with the iPad 3 30 pin). The USB to Ethernet dongle also has to be one that Apple recognizes.

Android is much simpler and with current units (nothing cheap and make sure that it has a Ethernet function in setup, some older versions don't) only requires a OTG USB to Ethernet dongle (I used a OTG cable and USB to Ethernet dongle). Dave's Mixing Station Pro is what I would use for tablet work. Currently I use a laptop PC since I don't have a Windows tablet.  As far as charging the iPad or any other tablet forget it too many complications and I never had much luck with the dual USB A cables. Get a tablet that can last thru the Gig with a full charge.
The fixed IP only setup is currently running and good so far (12 hrs). Even if that's a workaround I would use it only as a last resort. FYI the Apple Express was never known as a great WiFi router (low power = distance).
