Possible fix for LG TV WiFi dropouts


td47

Question

For those who get frequent WiFi connection drop-outs, I picked this bit of useful info from another forum. Note that this may well apply to many other LG models than the C9, as they often use common WiFi internal cards/modules:

"Network/Ethernet/Wi-Fi

Problem: C9 [or other models] will lose the wireless connection and you have to reconnect daily (but wired is stable);
Conditions: TV is connected to a 5GHz router;
Cause:           (1) the router may be unstable on the 5GHz band [possibly too far from router]; (2) the router has the 5GHz band set on a higher channel - over 100;
Resolution: (1) change the TV to the 2.4GHz band
                          (2) set the channel [in the ROUTER advanced WiFi settings]!! for the 5GHz band below 100 (ex. 40-50) - [channel 36 is often OK]."

Another simple solution - just assign a fixed ip address to your tv in your router settings.

@Karan Batra That is more for fixing DHCP and IP assignment issues or IP address conflicts.  The issue I was posting about is to do with the fact that some devices (Smart TV's, some tablets, older or weak devices etc) have difficulties with high channel numbers, plus the fact the higher channel numbers means slightly higher frequencies within that 5GHz band, and more chance of signal strength issues due to obstructions (or thick walls, steel frames etc.).

Not contesting your solution but different people have different issues & when a device has a fixed assignment it is easy for it to connect even with interference.

      Hi,
      Ongoing problem!!
      About a month ago I switched from BT to Vodafone FTTP (Fibre) broadband (100Mbps)
      Since then I've had buffering on my LG TV (55UM7610PLB). This is connected to the router by ethernet cable.
      My first thoughts were to do with the internet connection, I checked and tested everything. Vodafone have also checked everything and Openreach have replaced the ONT. Still got the problem though.
      So, I've turned to the TV. The LG chat and phone help were pretty low level and not at all helpful.
      Google turned up a possible solution which involved resetting the location services and removing it's automatic status. This sort of worked. Watching UHD Frozen Planet 2 was bufferless. But the next day, watching ITV hub was worse than ever.
      You would have thought with an 100Mbps connection it would all work so well....but it doesn't.
      Is it the TV? 
      Is there a fix? 
      Any ideas much appreciated.
      Thanks
      Ron

      The new WebOS Home makes the TV feels more gadget-ty or app-y while the old home feels more like an appliance. Is there a way to get back to the old home view?

      LG Marks Next Major Phase of Its CTV Advertising Business

      SEOUL, Sep. 15, 2022 – LG Electronics (LG) today announced a rollout of LG Ads Solutions proprietary automatic content recognition (ACR) technology across LG TVs globally, beginning this September. The rollout will replace legacy technology and put the new ACR solution on millions of smart TVs across 27 countries in Europe, Africa, Asia-Pacific, Latin America and Australia.
      The new ACR provided by LG Ads Solutions is already active on LG smart TVs in the U.S. and with the rollout, LG CTV data will be available exclusively through LG Ads Solutions.
      “Since the LG Ads Solutions launch last May, the team has created tremendous momentum for the business globally,” said Chris Jo, Senior Vice President and Head of Platform Business at LG Electronics Home Entertainment Company. “This rollout of the new ACR is another great milestone that demonstrates its commitment to excellence, and dedication to bringing the best possible advertising solutions to brands and agencies around the world.”
      CEO Raghu Kodige said, “This rollout marks the next major phase of our global CTV advertising business with LG Ads Solutions. It is a highly significant moment for brands across four continents, who increasingly need to reach cord-cutters and light TV viewers who have migrated to OTT services, and to understand incremental reach over traditional linear TV services. Now with LG Ads Solutions, brands globally can plan, activate and measure CTV advertising using the industry’s best ACR data set to help guarantee campaign success.”
      The ACR data, which is in compliance with all global and regional consumer data privacy regulations, helps brands understand, in an anonymized fashion, how frequent certain TV ads were aired in any given household. For brands, this means it can increase frequency levels for underexposed households, cap frequency for overexposed households, win over households that are exposed to competitors’ ads, and more. Of major importance, it informs brands and agencies which households they are missing completely due to cord-cutting.
      The data can also be used to measure the effectiveness of ads, such as if an ad drove viewers to a particular TV show or movie, or if an ad led to the download or registration of an OTT app or service.
      LG Ads Solutions already powers CTV campaigns in over 40 countries globally. Now, brands in any country covered by the ACR rollout can immediately begin working with LG Ads Solutions to understand TV audience viewership in their country at a granular level, in order to pinpoint audience segments and optimize reach, frequency and ad effectiveness across linear and streaming television.
