I am not sure this wifi software conflict is an accurate cause of the set shutting off. I have the 60E7000 and I have experienced a similar issue only I have my internet connection wired (Router: Netgear WNDR3700; Modem: Motorola SB6120; both current firmware). I have had the set for about two weeks and its 120+ hrs broken in w/ slides. The problem has occurred about 3-4 times under two limited scenarios.
First, where exiting an app (e.g. Netflix) back into the Smart Hub screen. Immediately after turning the set on I entered the Smart Hub and then Netflix, as soon as these actions could be taken by me. Once in Netflix, I immediately hit the exit button on the remote, was asked, "Are you sure you want to exit?" and then selected "yes" to exit back into Smart Hub. This "Are you sure you want to exit?" screen did not close for what appeared to be a relatively long time (20 or so seconds), but eventually did bring me back into the Smart Hub. When trying to navigate in the Smart Hub to another app, the TV appeared frozen. I tried highlight a different app a couple of times but it remained unresponsive. About 30 seconds later the set turned itself off and back on again.
Second, with much less context, occurred when setting up my personal icons on the lower portion of the Smart Hub screen. I created a folder and was moving some apps into it. I had already moved a few apps into the folder just seconds prior, but when I tried to move another one (specifically, I took the last action needed in order to execute the move), there was a relatively long "freeze" and the set turned off and back on again. Upon checking, the app I was attempting to move when the TV froze was actually moved into the folder.
This is a bummer - I just went through similar issues on two new 2011 and 2012 SONY LEDs (which by the way I had to learn the hard way that I will never buy another SONY product in my life). This phenomenon in my prior SONY sets was the harbinger of the three blinking red lights of death, the apparently irreparable demise of the set, which occurred only weeks after the turning off and on by itself started. I hope its not the same case with Samsung plasmas.
On another note, as many people have said, the screen switching to complete black where a scene is particularly dark is actually very annoying at times. Generally, I do not notice it, but when watching at night the on and off of the cell light can be pretty bad; prolonged dark scenes make it appear like your TV is just switching repeatedly between off and on with a black screen. This has a nasty way of working with the buzz to make it more irritating as when the screen switches off the buzz stops and kicks in when it comes back on... its like a flashing alarm. Along those lines I will interject to say that the buzz itself is really not bad on my particular set and It does not generally bother me even though noticeable (viewing distance approximately 12 feet, wall mounted 1.3 inches from wall, using movie mode with celllight at 20 & gamma -1), but quiet and dark scenes that generate this flash alarm effect is very irritating. I have read that setting brightness to more than 45 has stopped the screen off at dark scenes effect from being triggered but I have not yet tested it.
Otherwise, the PQ is really great so far, and I really love the TV. I have been messing a bit with the calibration, but I am nub at this stuff and have been trying other peoples settings. Since I don't have glasses to do THX and I don't know what to look for when using the RGB mode in "expert pattern2" I have only been able to set contrast, brightness, gamma, sharpness, etc. based on "expert pattern1." On that subject, does anyone know of a guide (or does anyone qualified
have the inclination to create a guide) that explains, step by step, how to use Samsung's
"expert pattern2" for setting color space, white balance, and 10p white balance?
