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!

Can't seem to find instructions for how to get into secret menu for my KU6300 with the smart/slim/whatever remote. Do you happen to know?

My Samsung Smart TV was connected to Wi-Fi but there was no internet on it. I tried a router reset and it was fixed. Followed the linked tutorial.

Hi @RKShukla Glad your Wireless Internet on Tv working now , certainly router reset is one of the fixes.       Good tutorial, members have mentioned some of these.    Useful   that some of the error codes  and  solutions included.

Found it!!

The issue is with the wireless authentication of your router. Your’s probably is set to WPA3-Personal. Just change it to WPA/WPA2. If that doesn’t work then you can try by removing wifi password on router.

[JAMES4578]

Certainly could be issue  if authentication is set to WPA3-Personal.  Settings on my router are

WPA2-PSK (AES) and   WPA/WPA2-PSK (Mixed Mode)

I would though point out that there are security risks in removing wifi password and if possible this should be avoided,  it is also best practice to change the password from the default one.   See some more information here: https://www.ricksdailytips.com/secure-home-wi-fi-network/

Hope you are well. Your details steps to fix the wifi issues in https://technastic.com/samsung-smart-tv-error-codes/#Samsung_TV_Error_Code_102 are very good. However, even after trying everything I was not able to get my TV(UE70TU7020WXXN) connected to the Wifi ( it works fine for Mobile hotspot though). Do you think I'm not doing it correctly or there are any other things I need to do. Appreciate your help with this.

How long do you have to hold it until it reboots? Does it come back on?

[RKShukla]

Hold it for a few sends until it reboots. You can use other tips too if this doesn't help.
