Question

SMART TV "Network Interference Occurred.Try Again Later."

by Jun 23, 2011 1:02AM PDT

I recently bought a D6530 SMART LED TV and I often have
difficulties gaining access to the Samsung Apps to download new Apps or use
already downloaded and installed ones.

When
I click a Samsung Apps button, I often receive the message "Network
Interference Occurred. Try Again
Later". The same applies when I
attempt to access other Apps such as BBC iPlayer.

I have been successful on occasions and used google maps, BBC iPlayer and the 3D
video clips but often appear to be locked out.

I have connected both wired and wirelessly but it makes no difference. I have
also re-started my router several times.

I experience the same difficulties if all other devices on the network are switched
off.

I have switched off the TV, switched it back on again and waited a few minutes
before re-attempting access to the Smart Hub to allow connection to complete
but to no avail.

The TV is apparently not always remembering my wireless encryption code and I
have to re-enter it sometimes to access the Internet. However, sometimes I am
asked to enter the code, decide not to do so, watch TV for a while, attempt to
go back onto the Hub and am successful without entering the code suggesting
that the TV had stored the code after all.

Per TV Contact Us screen:
Model Code - UE46D6500
Model - UE46D6530WKXXU
Serial Number - Z8HM3SQB400969T
Software Version - T-GASDEUC-1010.1
My ISP - BTInternet.com
Router - BT HomeHub v 2.0

Could anyone please advise of a solution to my problem or Samsung please let me know when you expect to be able to release a fix for my
difficulties.

PS - I assume that the Internet site that the TV attempts to connect to is not
being overwhelmed with access attempts resulting in the unavailability of the
Hub Apps!

Go to the Smart TV screen (not the apps log in, just the home screen). On your remote push the fast forward button then "2", "8", "9", then the reverse button...you should get a list of countries, make sure its "USA" (I'm assuming this is where you are)

Still no luck after updating the country
by aaasdfeeeeee Mar 4, 2012 10:18PM PST

I've updated the country to USA and still have the network connectivity errors come up, although they are less frequent.
I'll need to try the 8.8.4.4 dns ip to see if the problem goes away entirely, I've tried 8.8.8.8 and it did not make a difference.

Of all the devices I have connected to my network, only those using Smart Hub, a TV and a Blu Ray, are having problems. Even the Samsung TV with the older Internet@TV portal works fine.

Samsung, there's something to fix on your end related to Smart Hub, admit it, it isn't people's networks.

Can't make it work
by Hpstp Jan 5, 2014 2:15AM PST

I know this thread is very old, but I just found myself with this same problem. I've had a Samsung LED Smartv (5500) for about 3 years, and never had problems with it, but suddenly it just won't connect to my wifi anymore. Sometimes itll even connect to the wifi, but itll say it can't connect to the internet.

Ive now restored my TV to its factory settings, yet it still won't work. I can't make the country options show up - what is the smart tv home screen? I assume its the smart hub main screen, but it wont work there or in any other screen Ive tried.

Any other possible explanations? Nothing else has changed, and everything else works fine on my wifi.

Thanks!

Network Interference
by Jul 10, 2011 11:50AM PDT

I had similar problems with my Samsung BD 6500 Blu Ray Wifi player. After checking all the router settings, two rather non-technical things solved my problems: (1) Move the player closer to the router and (2) correctly setting the time zone on the player.

salaar_12,

And the tv was purchased in the us and it is being used in Pakistan .

What Apps do they have available for that region?

This may be the problem. Are these features available in the region you're trying to use them in? It may require a call to the service center in that region. This is beyond what I can answer, but may point to the issue.

salaar_12,

I can only assist with U.S. inquiries. I don't have any way of assisting when units cross borders, or what happens for individual apps as people attempt to access them from areas the content owners don't allow.

I'm sorry, I just don't have that information.

Possible temporary solution for people on Bell Canada HSI...
by Nov 20, 2011 11:45PM PST

All,

After troubleshooting this issue (it helps that I am a telecom engineer by background), I found a solution that worked in my case.

I did a packet trace on what SmartTV was putting out into the network, and saw that I was getting ICMP failures to the Samsung servers.

So, I made a change in my network settings.

I substituted Google's DNS server (8.8.8.Cool for Bell Canada's DNS server in the network settings. Just change the factory DNS setting from "Auto" to "Manual" and put in 8.8.8.8 (8.8.4.4 should work as well), instead of what the providers DHCP is sending the TV.

This fixed the problem, and the TV downloaded all it's firmware, updated itself, and everything worked.

The issue is somewhere in Bell's network (either their DNS, or, their CPE devices), so, I sent of my packet traces to Bell's technical support guys, and we are working through the issue. I don't work for Bell Canada, so, don't ping me about network issues!

This worked for me, and hopefully, it will work for some other users running into the same issue.

Answer
the problem is with the ARP request format
by Nov 29, 2011 4:55PM PST

This isn't entirely applicable to the original problem, but the problem has the same symptoms ("network interference occurred") and a Google search will lead people to this page so I will post my findings here.

Short answer: The TV's wireless interface and the wireless router speak different protocol formats. Nothing you can do will help, except buy a different wireless router and hope it speaks the same protocol format as your TV.

Long answer: The TV asks the gateway its MAC address via ARP. The gateway is your wireless router. The TV is using an ARP packet with an 18-byte trailer (padding). Your wireless router doesn't like the trailer, so it ignores the ARP request. The TV never receives the gateway's MAC address, so it won't ever talk to the wireless router. I verified all this with WireShark on my laptop connected to my Linksys WRT54G wireless router. The solution requires Samsung to release new firmware for your TV which uses an ARP request with no trailer (likely to take months).

Unfortunately I will have to return my TV (Samsung 6050) back to Costco.

Same error.....different reason.....
by dsarlis Nov 29, 2011 10:22PM PST

Yes......I get something completely different from you, since, I am not using the wifi port on the Samsung. I am directly wired into the CPE (a 2wire modem/wifi router that Bell uses), and don't get any ARP messages when I pull the trace from WireShark.

I get an ICMP error back from a DNS server in Korea, ns11.whois.co.kr, telling me that the port is unreachable. So, this could mean a few things from Bell's perspective, and what they might be doing with their NAT or firewall filtering. Once the Google DNS goes into the Samsung, the port becomes reachable, and all is well.

Certficate Authority
by j-list99 Nov 30, 2011 8:29AM PST

jhbaxter:
I also have 6050 that will not connect to the internet, however, I am not convinced the ARP trailer is the issue, as most EthernetII ARP messages have a trailer. You may be confused because outgoing ARPs may not have a trailer in WireShark (as it may be added after the capture in this case), but incoming ARPs do (as the trailer was added before the capture in this case).
Regardless, I captured traffic inline between my Samsung 6050 and I see a TLSv1 Fatal Error due to an Unknown CA when setting up an HTTPS connection with Samsung Electronics. I think that is problem. Samsung is using a CA that our TVs didn't ship with. Regardless, if they can add the new CA to our TVs, that would fix the issue (assuming I'm not off in the weeds).
My theory, in layman's terms: In order to communicate securely with Samsung's servers, our TVs have to have a certificate (file) stored on them. They don't.
If anyone knows how to peek at Samsung's CA store or has any insight into the feasibility of getting a CA update (or has another theory) I'm all ears.

CA store
by egumtow Nov 30, 2011 4:20PM PST

You might be able to list the CA store by gaining shell access through the RS232 interface after putting the TV in to debug mode. Gaining shell access is not easy to do but apparently it has been done (I won't provide a link here, but I stumbled on to the page by searching for "rootfs.img.sec").

Also, I am less sure about my earlier ARP claim. There does seem to be an issue but it may not be the issue that is preventing the wireless from functioning.

Network Interference Try again Later
by Mar 25, 2012 3:29AM PDT

Had the same issue and the TV is located in Alaska, reading the manual it does state to change channels on your router due to interference. Not in thoses exact words. Go to your router and log into the router config software and change the channel. Most routers are preset on 1, 6 or 11. Mine was under WLAN settings and I changed it to Auto. The intereference is also due to your neighbors. After a month of not being able to access the SmartHub I am not up and running and everything has updated. I just cant believe that either Samsung or HD Tech has come up with a viable solution.
You can also do a search on changing the channels on router and a whole lot of information will pop up. Good luck and happy Smart Hubbing...

The problem is that Samsung sells CRAP.
by May 5, 2012 12:58PM PDT

They are clueless.

They over-promise. Their technology puts them somewhere between the very first Hyundais and very first Kias.

South Koreans succeed only after they sucker Americans to flood billions into their R&D.

I will NEVER buy another Samsung product again.

Samsung TV Network interference or invalid MAC Address FIX
by May 29, 2012 9:32AM PDT

I too had the error "Network interference occurred. Try again later." During troubleshooting I also tried the network test and got an error for "Invalid Mac address". I have a 55 inch LED Samsung (UN55C6800UFXZA) with a Samsung linkstick LAN adapter. After months of successful connectivity to my wireless network, it suddenly lost its connection and nothing I tried would fix it.In the network set up it couldnt find any wireless network's within range, though all my other wireless devices had no issue with wireless networks. I also had my router set to display my SSID and had MAC filtering turned off, as needed.I knew the issue was with the TV and not my wireless network. I could only connect to my network from a wired (Ethernet) connection. I scoured the web for solutions to no avail. Finally, from navigating Samsung's troubleshooting webpages I found the solution: reset the TV to the factory settings. Not an ideal solution, because you have to reconfigure EVERYTHING but it worked. Below are the steps from Samsung's website for my model of TV.
The fix (from Samsung's site:<span lang="">
<a href="http://www.samsung.com/us/support/owners/product/UN55C6800UFXZA"><font color="#0000ff" size="3"><font color="#0000ff" size="3"><span lang="">http://www.samsung.com/us/support/owners/product/UN55C6800UFXZA</font></font><font color="#0000ff" size="3"><font color="#0000ff" size="3"></font></font></a> )
If the Mac Address test fails during the network test, you should perform a Factory Reset then run the network test again. Important: A factory reset will reset all settings of the TV including Brightness contrast volume and all other settings.
To perform a factory reset follow these steps:
1. with TV turned on, press and hold the EXIT button on the remote for 10-15 seconds.
2. After 10-15 seconds, a message will appear informing you all settings will be reset.
Use the Left arow button to select OK then press the ENTER button. The TV will power off by itself.
4. Turn the TV on and follow the onscreen propmpt to complete the initial setup. You will have set up your cable/dish connections, as well as reconfigure your accounts for Netflix, Vudu, Blockbuster, any other apps you had configured in Internet@TV, as well as reconfigure any other TV settings.

Re-run the Network test again. (Mine tested fine after factory reset)
If the Mac address test fails again, connect the wireless LAN adapter (linkstick) to another USB port on the TV. If the network test still fails, the wireless LAN adapter (linkstick) requires service. Please create an online service request with Samsung to have the adapter repaired.
If the Mac address test passes, but another test fails, go to the list of network tests from Samsung's website
If all tests pass, the TV is successfully connected to your network.
I hope this helps someone else with this issue as I wasnt able to find this fix on any other postings.
Happy streaming

Easier solution than I expected
by May 10, 2014 9:05AM PDT

After fiddling with the tv and router and internet connection, the solution turned out to be quite simple. In the tv, after successful connection to the router, click IP setting and change setting to automatic (from manual). That did the trick! I just couldn't believe it was that simple after wasting 2 hrs trouble shooting
