I experience frequent "network connection lost" problems - without using DLNA at all.
For me, i It happens just by watching a channel which includes HbbTV information (Danish TV DR1) .
Often, when the tv gets HbbTV info to show the "DR.NU (red dot)" logo in lower right corner, it will blank out the screen and show a [1[2[3 Connecting... STOP]]] panel. Sometimes it briefly shows a message about "network connection lost" (in Danish) first. But the common thing is that this pop-up never disappears by itself - I have to press OK to confirm the STOP button.
The TV then goes completely black for 2 secs before returning to the channel/program I was watching.
So I think the problem lies deeper than DLNA -- it's at the root of the network stack or interface(s) affecting all services using the network. Insanely annoying for a "net tv" !
Good WiFi connection 54 Mbps -- tried with static IP and DHCP settings - happens with both.
Philips support - are you getting any of this?
Your silence is rather ominous. Do you not care?

While looking at video files from HD every app. 30 minutes the TV loses connection with the network.
After switching the TV off and on the problem is "solved".
So it looks quite clear the the problem is in the TV.
It would be very nice if Philips could make this thing better in a next software update !!
I'm not really sure that the problem resides exclusively on the TV 's software, since I have solved it completely by simply changing the router which it was connected to. I've tried with an old one, and also with a brand new TP Link TD W8970. It is true that there is something interfering with the router caused by the TV and NOT with other newer Philips TVs. (I also own a 32pfl4007h and it has never given me any sort of problem).
It has to be simply a certain combination of factors that makes the TV disconnect from the media server. (This does not mean that Philips is not responsible for solving it. Of course they should have done it a long, long ago).
I know it's not fair but, I'd try with another router and see if luck smiles to you.
