The device will work with almost any OS, including Win 7. It sounds like your NAS is not receiving DHCP from your router for whatever reason. Can you directly attach it to your PC and set a static IP address of in the 192.168.0.X range (anything BUT 192.168.0.32 since this is the default NAS ip). Then try to use the utility or simply try and connect to the devices web url via http://192.168.0.32/ . If that works then you can go into the LAN section of Setup and set a static IP in your routers range, something like 192.168.1.32 and then once you have saved the configuration you can reattach it to your router and reattach your pc to your router and make sure to set your PC back to DHCP instead of static (unless you had it on static already). Then once everything is hooked back up to the router try to connect to the new ip address IE, http://192.168.1.32/ .
