Are you certain you have the correct ip address?
I have Windows 10 also and have no issues getting to my bdp2. Nothing special, just shows up under network. No home group set up or anything like that.
I did set up my router to allocate the same ip address every time the bdp2 connects. By default, most routers will dynamically assign an ip address each time a device connects. If that happens, you will not usually get the same ip address two times in a row.
You can check the ip address the bdp is using with the arrows on the front display. I THINK it's down, left, left (that was my interpretation from the last page on the most recent manual anyway).
