I would get your graph looked at. The packet loss is not right and not normal - it will affect pretty much anything you do.
There were 5 or so graphs showing the same loss on http://community.plus.net/ping-graphs last night, so we're having a dig.

Quote from: stealth I have had a samsung tv for two years and it has functioned properly on the internet.
This was until today, I selected I-Player and told my the connection had interference. I checked it out and it told me there was a connection to the router but not to the internet.
All other devices such as telephones, iPad and pcs are working fine.. But not the tv. I tried 8.8.8.8 google dns and the tv connect straight away..
So the question is why will my tv not connect when the dns setting is auto, it has been in this setting for two years...
David
I have exactly the same situation. I thought I was going crazy, both my Samsung TVs not connecting, but Sony TV OK. Also Samsung tablet and Galaxy S5 OK - I cannot understand why only TVs are affected. This has only been a problem for me in the past two days. When I telephoned support they told me of the 8.8.8.8 solution and this all right, but I would like to know why auto DNS suddenly stopped working.
As usual, nothing on Service Status about this. There never seems to be about specific problems, only general stuff.

There's not really a lot we can put onto a Service Status whilst we're investigating it.

Quote from: Nick The issue on this thread is specifically about Samsung TVs. There may be a general DNS fault but this is surely different to the Samsung TV problem?
This general issue becomes specific to the Samsung TV for two reasons as indicated by npr...
Quote from: npr TV's probably don't have a dns cache, also CDN servers tend to have a short ttl time making them more sensitive to flakey name servers.
The TV probably does not cache (remember) the name resolution and thus needs to ask for it more frequently.
The CDN servers (content delivery server's) DNS registration lifetime values are shorter than would be the norm for servers, thus there is an increased need to look up the name resolution again.
Combine those characteristics with an intermittent DNS fault and you have Samsung TV's playing up in unexpected ways.
Seems Samsung has a number of issues with their TVs at present - only last month mine started switching itself off and on all on its own. That turned out to be an issue with digital text messages from Channel 4 - only seemed to affect Samsung Smart TVs.

All it takes is the one duff entry on the PN DNS servers and every customer with a product that uses that URL would be affected.
My Samsung TV grabs its DNS from my Linux DHCP server which is set to serve out the Google and OpenDNS addresses so I haven't noticed any issues personally.

I suspect the same as others and that Samsung ping a set address and DNS is a little slow / tricky and they don't get a response instantly that is the end....
All is well for now but keep the 8.8.8.8 in my mind !
Thank you for all your answers ..
