I did not say that the Router is the cause, i did say:
You are alluding that the problem lies with a router, but what makes Philips be so sure about that? For example, my Asus RT-56U can also operate as a DLNA server. Have they screwed it all up?
We can and will not say that the Router is the cause. However, look to related Threads in this Forum, most of the Threads can be summarized as "without the router in between it works".
Most of the Times, the Routers has some own UPnP Settings, they can and will interfere with all Devices, causing temp. loss of connections.
