How to get smart tv internet working properly?

The router isn't far away. It's right next to the TV. I don't even know: for all I know it might already be using ethernet.

Oh and by the way, my first response was incorrectly edited, removing detail which may or may not be helpful. The actual message displayed is this:

Service is not available because of poor network connection.

It's best not to make assumptions. That was you won't make false assumptions about what someone's message was meant to say.

ok it's still not working. Before the message 'Service is not available because of poor network connection.' there is this:

BR with square brackets around it

apparently that's not allowed here so I had to spell it out in words. Very convenient: not.

BR in square brackets is a lay-out code meaning "new line". So it disappears. Sorry for that.

So your TV uses WiFi, not an Ethernet-cable to connect to the router. What happens with the quality of the network connection if you use such a cable?
And how fast is your connection with Internet if you do a speedtest on your laptop or phone, also connected wirelessly?

idk. I know how to find out but no time atm.

idk if it uses WiFi or Ethernet.

the 3rd reply here, which for some reason it is not possible to edit is in response to the questions about speed.

The thing is that until while ago the internet on the Smart tv was much better and I never saw this message. Occasionally a video would 'crash' and I'd have to reload the page but there was never a problem with loading the page, as there is now.

The problem started at some point after another problem, which was that youtube would no longer play in full screen. The youtube problem is because the firmware version needs to be updated, so I guess the other problem could also be due to this.

Ok thanks.

'...I defer to Samsung.;'

Idk what that means.

While I've worked on this issue with many folk, a few DEMAND it get fixed. Unless I'm on a paid call I tell them it's Samsung's to fix. That is me deferring to the maker.

These Smart TVs are quite the tar pit area. I learned long ago never to commit to fixes since the makers have not cleaned up their act.

That doesn't mean I won't try but there are limits to what we can do.

Ah ok. Thanks: that's helpful.
