I've the same problem.
I've tried various titles and all says the same: ensure you're connected to the internet while at the same time, the 4 tests show a v before the test lines. I've removed the phone line and then it says that internet connection is not ready (a cross before the last line)...
Strange isn't it?
I've the same questions as yours: should we forward the port? which one?
If you've found a solution in the meantime, please share as I haven't found that many issues like this one or at least, nobody's talking about it!.
Have you tried Samsung's helpdesk?
my new BluRay is unable to connect to the internet, but it passes al the network tests (the V shows up before the test lines), and after the tests it says that the network doesn't function properly (don't know the english line, my OS is in dutch).
When I enable DHCP it recieves an IP adres from the modem, so the network should work.
I have the latest firmware.
When I connect my laptop to that network cable, it is able to go online.
I read messages here about that the network cable shouldn't be to long, but I guess that that isn't an issue when the BluRay gets an IP adres from the modem.
The firewall from my router is disabled, so that can't be the problem.
Maybe I should do port forwarding? but wich port should be forwarded?
My BluRay doesn't have netflix or pandora and such, it is just for BluRay live and Divx that it needs the network port.
Can somebody help?
