FIRST-HAND EXPERIENCE
Returning home one evening, TV kept showing message informing me
NO INTERNET CONNECTION. Yet, my TV is hard wired to the Network as well as operating wirelessly. No issue with my PC or Tablet. Both connected to the Internet.
Tried to turn on my portable air conditioner via ThinQ app. Same issue as TV. After going through all the basic troubleshooting steps to no avail, I reset my router/modem by unplugging it from the wall, waited a minute, plugged it back in, waited 2 more minutes and the Internet got restored to the TV.
As for the air conditioner, I had to reset the appliance as well by unplugging it from the wall, wait a minute, plug it back in, wait another minute and the Wi-Fi connection got restored.
Had a voice message on my home phone from my Internet service provider apologizing for the longer than usual temporary Internet service disruption that day.
Should this have helped you restore the Wi-Fi connection to your TV, could we please ask you to report the incident to our
call center where an agent will ask you additional information details to document for the software engineers.
Cause and Symptoms
First off, let’s get the basics out the way to ensure root cause is not from a peripheral device.
- Was anything recently changed in your Home Network environment?
- New router? Router moved to a different place in the house?
- New settings update on AP router? (i.e. changing to 5GHz from 2.4GHz)
- More household devices connected to Wi-Fi Home Network?
If none of the above have been changed recently, then let’s examine some options that should resolve your issue
Some customers have questions why is this only happening to the TV and not to their mobile phones. A television is meant to be stationary while the phone moves around a lot. So, phones are prone to feature a much more robust (obviously more expensive) Wi-Fi signal reception chipset than those found in televisions. Televisions are also shielded to alleviate the spreading of Electromagnetic Interference towards the viewers.
The downside to a shielded TV is the fact it works at limiting emissions as much as limiting receiving radio signals, the reason TVs always required being hardwired to an antenna to receive broadcast TV signals. Also, take note that a television screen is much, much larger than that of a phone, a tablet or a personal computer. The bigger the screen, the more EMI shielding.
Features that, whenever enabled, for some obscure reason, have been known to be fussy and disrupt Wi-Fi connectivity to the television.
Television :
- QuickStart+
- DNS Server
- Service Country (set automatically)
Router :
- 5G Band steering
- Password encryption method

Customers who have resolved their losing Wi-Fi issue shared the following information on the Internet :
!
Method 1
Change AP router bandwidth frequency to 2.4GHz by disabling 5GHz band steering.
It might be a good idea and opportunity to change the Network router’s encryption method to WPA2-AES or WPA-AES . Previous WEP or WPA-TKIP or WPA2-TKIP encryption methods have been known to become unsettling after a Software Update often causing Wi-Fi connection to drop inadvertently.
Method 2
Uncheck the “Set Automatically” option in the SERVICE COUNTRY options and select proper country of residence.
- Go to General Settings then System then Location then finally Service Country
- Select a country of residence other than yours (temporarily)
- Accept by clicking YES
- TV will reset.
- Again go to General Settings then System then Location then finally Service Country
- Select your country of residence making sure to leave Set Automatically unchecked.
Method 3
Changed DNS server IP address to 8.8.8.8
- Go to Wi-Fi: Settings → Network → Wi-Fi Connection → Other Network → Advanced Wi-Fi Settings → Edit → Uncheck “Set Automatically” → Select “DNS Server” → Input 8.8.8.8 → Click “Connect” button.
- Finally, make sure your TV software is updated to very latest current version.
Method 4
Disable Network IPv6 feature option in TV on-screen menu.
Once you have established your Wi-Fi connection Go to Settings → Network → Wi-Fi Connection → Advanced Wi-Fi Settings → IPv6 On - Off. Disable (turn off) feature option.
