W7 64 bit works fine for me. I suspect something is amiss with your network. I have a cheap 1Gb network with a TrendNet wireless router and Trendnet switches. Cables are Monoprice CAT 6. All my Sooloos units use DHCP. No reservations and no static IP's. Try swapping network cables and jacks on your switch. Just noticed that this router uses something called SharePort, make sure that feature isn't enabled.
