Man, I haven't had those problems. I configured the wi-fi and it synch's from my driveway. The home unit has been the most easy and flawless to use so far. I plugged it into my home ethernet network, it saw the simplecenter server (and vice versa), works great.
After goign on a roadtrip this weekend i did find I need to adjust how I mounted the hard drive. At highway speeds vibration seems to be just right that it was causing the thing to skip, or glitch while playing music. If I slowed down to slower speeds, it played perfectly. I mounted right to the rigid underside of the back window and I'm going to try some rubber around the screws I used or something to insulate the unit from the vibration.
But man, despite that, I friggin love this thing. So badass.
