Samsung smart TV drops WIRED connection

by Writerman-UK / May 2, 2014 1:41 AM PDT

I've seen a lot of comments from users whose Samsung Smart TV keeps dropping its internet connection but the discussions are usually centred around the WiFi component of the link. I'm not using WiFi on my TV. Mine is hard wired to my router via a couple of HomePlug units, which send IP over the domestic mains wiring.

When I first got the TV, a bit over a year ago, it worked fine. Suddenly, it has developed the fault whereby it regularly loses its Internet connection every ten to fifteen minutes. Each time, if I go into the menu, internet settings, and retry, it reconnects OK - only to drop out again a few minutes later. This renders any sort of catch-up TV unwatchable and invalidates the reason for buying a Smart TV in the first place.

Given that it used to work, something must have changed. Perhaps an over-the-air firmware update? Alternatively, around the time it started going wrong I switched my broadband supplier from TalkTalk to BT. BT supplied me with one of their Home Hub routers. I don't know for sure whether the problem started at precisely that moment because I don't watch catch-up TV all that often. However, it is certainly true that TV connection has never worked reliably since switching. Could there be some sort of incompatibility between the Samsung TV and the BT router? Anyone come across such an incompatibility before?

Any ideas for a fix or work-around? I read somewhere that setting up an explicit DNS address could sometimes help. Anyone have more information on that idea?

About the DNS. Good idea.

Google this -> How to use Google DNS.

Plenty written but I want to broach the subject of Net Neutrality since with it's passing we can no longer be assured of the ISP or others not tinkering with the connections.

Can't change DNS with BT
by Writerman-UK / May 2, 2014 5:31 AM PDT

Thanks for the link. After investigating further I discover that BT have disabled the ability to change DNS settings in their Home Hub, so I am back to square one. Any other ideas how to get my Samsung smart TV to stay connected?

All the Samsung TVs I've tried...

Allow me to set the DNS in the TV's network settings.

Strange choice on BT's part but let's say they wanted to keep their clients captive and only resolve addresses of their choice (for your protection?) Well, I can override what the DHCP hands out in almost every device so I'm back in control.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
