Can't be found. Many DNS (see google for tech terms) don't have an entry for the device maker's servers.
I see this a lot on Samsung gear (message to Samsung, you can fix this by trying DNS 8.8.8..
So give that a try. Set the DNS manually in your device to 184.108.40.206 before you call the bluray maker's support. Also, the player must have the latest firmware.
So my RV park has free wifi. I am trying to connect my bluray player to it. It shows a full signal and connects but says "connected to network but no internet connection". What does that really mean? What do I need? A router, modem, extender? Please help. I don't really understand all this.....
