Samsung Smart TV Not Connecting to Internet

[13022009sy]

I recently purchased a Samsung Smart TV 8 Series. When I try connecting it to the internet by LAN/WAN it says connected to router but not able to connect to internet, contact your ISP. Sometimes it connects and then goes to the previous status in a short time. I am using a Leoxsys 54 g-dl 54madsl2+router and I have a bsnl ul750 plan. Both Samsung and bsnl tell me its not a problem on their side. I am able to access internet on other devices through the same plan. I have tried using an alternate dns server.

I'm new here & I don't have a solution to this thread but I can't see how to post like everyone else. I am in Canada, have a 3 yr old LN40C630 that I only just started using the networking & everything was fine till Feb 24/15 evening. None of the posted suggestions worked. Called Samsung today, downloaded via USB the firmware update, network status all checks BUT still no connection.

Back to Samsung support

I had the same problem with my Samsung tv and tried the following:

1. Changing the DNS server to the default google 8.8.8.8 then to comcast default 75.75.75.75 and 75.75.76.76- This didn't work
2. Changed the parental controls- didn't work
3. Hard reset modem- didn't work
4. Reset tv to default- didn't work
5. Changed the security encryption of wifi to WPA-TKIP- didn't work
6. Tried connecting with ethernet cable- didn't work
7. Called comcast and they were absolutely no help
8. Finally chatted with samsung and they asked me the model # of my TV and then told me to set the DNS server to 151.80.14.237 and it worked. Not sure if this will work with all samsung TV's or if you have to find out what you need for you particular model number but as soon as i put that in it worked. It was amazing.

I've had my TV for almost 4 years, have been connecting wirelessly to our FiOS service without any issues all this time. Five days ago we got a new router, and aside from switching from WEP to WPA everything stayed the same, and all the devices in the house worked fine.

But three days ago, the TV suddenly stopped connecting to the internet. Connection to router was fine. I switched to a wired connection and it made no difference.

I tried ALL the remedies suggested above (except for TKIP, because I don't want to torpedo all the other devices in the house) and NOTHING worked.

Until this:

---> set the DNS server to 151.80.14.237

THAT worked. Thank you, Maverick45!

I began having trouble this evening as well. I have Cox.. It started out as an issue with Hulu plus not connecting (clock error) which led me to a hulu site that said I should reset my smart hub. Now I can't get Smart Hub to connect because "the network is not stable". I reset my modem and router, even unplugged the TV. Any body else having these symptoms or have a solution for this?

I am having exact same issue with my Smart TV. It started around 5 pm. Connection to Hulu Plus failed. I reset the Smart Hub and now I can't connect to the internet. Very frustrating!

I started having this issue as well with my samsung un32eh5300, it started yesterday. It was working fine the day before. But it did have those symptoms you described, first it couldn't connect easily to hulu and then it kept saying clock was not set. And then finally when I came home yesterday it wouldn't connect to the internet at all. It connects to the router but not to the internet. I tried everything, adding it manually to my router, reset everything, unplug everything. Until finally! Something worked!

Change the DHS server manually to:
151.80.14.237

I have the same issue.
DNS 8.8.8.8 didn't help

I have encounter same issue on my Samsung Smart TV ua40es6600 for these two days which running well for past two years.
This looks to me a global issue around the world and the resolution point to everywhere include router, hub and TV setting.
I try all those solution post on the web but none of them resolve my problem even with Samsung's technician onsite service. The issue remains there.
One thing weird is I could use cellphone to browse internet without problem through Smart TV Soft Access Point by cable RJ45 copper cable to Smart TV and enable Smart TV as a soft AP.
Another funky thing is I spent all most two days in all those try run and still can't get the TV through but it just got resolved but my 8 years old son.
He said he saw I keep trying on the Ethernet setting and always block out on the connection in between router to that earth symbol.
Then he did his try but click the internet browser symbol inside Smart Hub and go with two "yes" choice then suddenly everything back to normal include those APPs gone after I did factory reset on Smart TV.
It is now working normal with internet and all the APPs I have before. I guess the issue might be in Samsung side the Smart Hub Server/app and not thing with router or DNS, etc.
Hope this help.

Similarly to other Users I've been using my Samsung TV for just over 2 years now with no problems connecting to the Internet using a wired LAN connection.
A couple of days ago I rescanned the Digital (Freeview) channels to update the latest changes, this required me to go through a full Reset and Install. I skipped the Network setup part of the Install as I was happy it had all worked satisfactorily. Next time I tried accessing my usual Online services (BBC iPlayer and Amazon Prime Video) it reported it could connect to my router but unable to make a connection to the Internet.
I checked the Network settings - all correct, pinged the TV satisfactorily from my computer. I also tried changing the DNS server address.
The TV still reported no connection beyond the router.
I then tried the various suggestions found on this and other forums with no success.
Today I had a breakthrough, and I'm not sure which of 2 things I did worked as I foolishly went on to step 2 without checking to see if step 1 had fixed the problem, but this is what I did :-
(Step 1) I completely unplugged the mains power for 30 seconds, plugged in again then repowered the TV.
(Step 2) I changed the Network name of the TV thus:- Using the TV remote control
I went to MENU then NETWORK then DEVICE NAME and changed the name from [TV]Samsung to [TV]SamsungTV.
Having played around with computer networking for some years I believe the actual name you give it is not crucial as long as it differs from the earlier name, but don't use any spaces or characters other than letters or numbers.
(please note the [TV] part is not changeable and actually does not form part of the Network name of your TV)
All now works satisfactorily, worth remembering your TV today is basically a computer and will occasionally have problems like any other computer.

I chatted with tech support from Samsung some minutes ago.

It seems they have fixed the problem on their side. In case there are still issues they recommend to reset the SmartHub to the original settings.

So I just checked my samsung again and after 48 hours of no internet, it's finally back up and running again
