Samsung Smart TV stopped connecting to internet (wifi and Ethernet)

[Bobik]

Hello,

I am trying to fix my parents Samsung TV F6500 which has stopped connecting to Internet since a few weeks. Here is my diagnosis: The TV won't connect to Internet using wifi or Ethernet throught their usual provider. When I use my 4G phone as an access point, the TV connects normally.

These are the solutions I have already tried and that didn't work:

- Reseting the ISP's router + changing it's IP adress

- Factory reset of the Samsung TV (using the Auto-diag menu and the secret menu that you access pressing different buttons on the remote)

- Changing DNS to 8.8.8.8 or 8.8.4.4.

- Updating the firmware

- Calling the ISP's hotline

'

My questions are :

- Is it possible to do a factory reset that includes the Network connections?

- Has anybody had the exact same issue as my parents?

- Even after the factory reset, the TV continues to say that the firmware is up to date, is it possible to remove the updated firmware?

I am out of options and the Smart Hub is now useless. Any help would be greatly appreciated!

I am using Roku. I can watch Netflix, but Britbox is what keeps disconnecting from my wifi. I get a message that I am not connected to the internet.

I had this issue a too, the solution was the tv country code was set to USA.  

See there was a software update and it changed all the settings.

This worked. Used remote. Held until Logo appeared and restarted by itself.

yes this sucks and 3 hrs with Samsung "support" was no help at all

Samsung customer service said and I quote. "We know the issue it's a easy fix. But I can not help you your tv is out of warranty.

I have 4 Samsung TVs guess who is never buying a Samsung again.


I did a Google search to find a solution

I was able to get the WIFI to work and not drop. To do this I had to:

1. Log into my home router and allocate a static IP address to the WIFI. 

2. Go to the firewall section of the router and add an exception to the firewall to allow that static IP to pass through the firewall at all time. 

3. Enable MAC Filtering for the Samsung TV and add the TV to the MAC Filtering list.

4. Extend the DCHP lease to 99 days

This allowed the WIFI to work. I also have a ethernet cable hard wired to the back of the TV. I took similar steps here, but the smart hub diagnostics continued to say that the ISP was blocking the TV even after I added the hard wire IP to the firewall passthrough. I really want the TV on the ethernet and will continue to work but these steps have worked successfully so far. I have not had the TV very long and debated taking the TV back for a refund due to this issue. 

Just as FYI, I have used a Roku and Firestick without any issues.
