Switched to AT&T Fiber, and my Samsung Smart TV can't connect to my network.

Version: 1262

Model: MU6290

 

I recently switched from a local ISP to AT&T Fiber and am using AT&T’s standard default router/gateway and can no longer connect to the Internet. I had no issues with the old ISP, so I'm posting this under the AT&T Fiber Equipment forum.

 

At first, my Samsung 4K TV (model MU6290) worked fine. I set up a Wireless connection on my new network and experienced no problems. Then, I turned on the TV the next day, and it wouldn’t connect to the Internet.

 

I have scoured the Internet for hours trying to fix this and am at a dead end.

 

I have tried:

 

  • Manually setting up my DNS as 8.8.8.8 and 8.8.4.4
  • Connecting the TV via Ethernet directly to my router. It instantly says it cannot connect to the Internet.
  • Resetting my Factory Network Settings on my TV and setting the network up from scratch.
    • When I do this, I can see all local Wi-Fi networks - including my own - but cannot connect to the network.
    • When I tell it to automatically find the IP and DNS servers, it works for a few minutes, automatically provisions a MAC Address, and then gives 0.0.0.0 for all other fields (IP Address, Subnet Mask, Gateway, and DNS Server).
  • Unplugging and replugging my TV’s power cable. This will sometimes fix the problem until I turn the TV off and it disconnects from the network, at which point it can no longer connect to the Internet.
  • Manually provisioning a MAC address for my TV on my network.
  • Manually provisioning an IP address for my TV on my network.
  • Disconnecting my Chromecast from the TV and turning it off the network.
  • On the few and random instances when the TV has successfully connected to the network, I took a photo of the Network Settings it connected to the network. I then provisioned IP and MAC Addresses for these values on my U-verse network and manually set up my TV’s network connection via these values. It worked once, and then stopped connecting.

I can occasionally get the TV onto the network by unplugging/replugging the power cable and doing a Factory Network Reset. It does not work consistently.

 

Most puzzling to me is the fact that the TV does not connect via Ethernet when plugged directly into the router. I know the Ethernet cable works – I have plugged it directly into a Windows machine and Mac OSX machine and experienced zero issues with it.

 

Any suggestions?

Hello there @iPaisley,

We'd be happy to help out with getting your smart TV connected again! Just to clarify, is the TV the only device that is having any issues maintaining a connection to the internet?
Is the TV's firmware updated to the most current version? Please let us know so we can assist you further.

We hope to hear from you soon!

I am having the same problem, worked at the beginning, switched to fiber and wouldn't work.  I found somewhere on the internet to turn off the TV with remote and hold down OFF button until Samsung reappears on the screen and let go. This was working until yesterday- now all of my apps work but I can't get the Samsung Live TV to work anymore- it says it not connected to the network. This is not a great workaround because everytime I turn on the TV, I have to turn it off and go through the same process but at least it works.  Let me know if you find a better fix!

I've had this problem with my Samsung Smart TV since the day I hooked it up. Is this an issue with Smart Security? Is it blocking the TV's access to the network? 

Side note, I'm also having trouble with connecting a Ring Doorbell to the network and I'm thinking its the same problem.


Other devices are hooking up just fine, such as Ecobee and Sonos.

Also having this issue with my Samsung TV. I have to reset the network every time I turn it on. My Samsung Galaxy Note9 is also experiencing issues. I have to disconnect WIFI and use data to do anything online on my phone. All other devices, MacBook, Fire Sticks, non Samsung phones all work. My video doorbell also will not connect. I had AT&T WIFI previously with these devices and had no issues. It only started when I switched to fiber.
