LG OLED55C8PTA wifi issue after latest software update


Recommended Posts

Hi I recently updated the software to 5.30 version, and after that I noticed a weird problem with video streaming, in general issue with internet bandwidth. Usually my b/w is ~35 mbps so that is sufficient for 4k streaming on youtube or netflix. The issue is after running for 10-15 mins if I pause the video or go backward the network speed is thrashing badly. For example when I check internet connection on netflix it shows ~30-35 mbps, but whne that problem occurs and I check the speed again I see the speed is dropped to <1mbps. Same with youtube, it can't load 4k videos anymore as the speed is ~1mbps. I can realize the problem as the thumbnails load very slow with scrolling. This problem does not get away unless I restart the TV or disconnect from wifi AP and connect back. The router always works fine I mean when I observe the problem on tv I can run videos on mobile seamlessly and see a speed of ~40 mbps on the same router. The router is kept next to the TV so I don't think it is some issue with wifi distance etc. I don't know what to do. I tried resetting but it removed all my app but it was actually not a so called "factory reset". So software version remained same. To rule out hardware problem I want to revert to previous version of the software but apparently I can't downgrade the software. Is there any other approach to load some previous version firmware?

Using the ethernet cable has always been the workaround...you don't need to do the quick start thing if you're doing that.

Unfortunately, the firmware can't be downgraded. LG must provide another update to fix this asap. I am now relieved that other people are also facing the problem. My warranty has been over in May 20, and i was afraid that it is some hw related problem than i am screwed. Let's hope LG addresses this problem asap.

hey Debojit,

a lot of people have the same issue:

 

 

this guy pasted a 'fix', but i didn't try it myself:

I think I've found a quick fix, til LG releases a new update;

Enter the Network menu (Settings - Network) and make sure you're connected and just wait a sec.

then, close all open TV apps from the "recent" tab, and lunch the one you want again.

this works for me, hope it'll help anyone here.

 

 

fwiw in my situation whether the video was paused or not didn't matter. however i do agree it appears to be some sort of issue with the tv going idle on the network, and I can see the rx speed in the router drop to 6 (from 766).  it's possible that when i have been experiencing it i had already prebuffered the entire video and it went into some sort of network sleep mode and couldn't come out - but that's wild speculation.

In my case the easier solution is to just disconnect from the connected network and reconnect to the same one. No network switch is required. Only pain is every time I need to key in the password. And the real pain is unable to do a true factory reset. Does anyone know how to do a factory reset. I also downloaded the tv firmware from their website but they are saying that can be installed only if tv's present f/w version is lower than the one in the usb drive.

you can't downgrade the firmware.

and re: your post on reddit, if you install engineering firmware you run the risk of being marooned forever on that firmware and unable to access any future updates, so it's strongly discouraged.

Thanks for the comment. Looks like waiting is the only option.

Hi,

I faced exactly the same issue after software upgrade to the latest version similar like you have. I found a quick way around to fix it. You need to disable "Quick start+" from the General settings tab. After doing that re-start your TV and bang Wi-fi speed will be back where it should be. It's just one time process and then streaming will work flawlessly. 

Try it and hopefully it will work out for you as well.

/S

It looks with with Quick start disabled whenever I turn off the tv with power button the Wifi is getting disconnected and turning on again causing the reconnect to wifi. This is similar to my solution where I disconnect from the Wifi AP and reconnect back. But here I need to type in the pwd of wifi every time connect to the Wifi AP. So your solution is better :)

Great this way around worked for you as well.

Also, i have reported the issue to my local LG representative and waiting for a home visit to fix the problem. As soon as i got a solution from LG, i will post it here.

Since past 5-6 days even I'm facing the same issue even though my net speed is ~200mbps. Today after going through your posts above, I connected my TV to my router using ethernet cable. And, there was no buffering at all and it was working same as before.

So, looks like this is better workaround till LG comes up with a proper fix for this issue. God only knows when that would happen.

Solutions

  1. Use wired connection, fool proof solution.
  2. Turn off Airplay. Turn off Quick start (from General settings). Still you will encounter this problem but less frequently. Once this happens turn off the tv using the remote. As quick start is disabled, when you turn it on back the wifi connection would be renewed and you will get normal speed. So simple solution is turn off and turn on.

      Utilizing VUNO’s AI Algorithm, LG’s X-ray Acquisition Software
      Reduces Analysis Time by Detecting Abnormalities in Images

      SEOUL, June 22, 2021 — LG Electronics (LG) today unveiled an improved X-ray acquisition software for the company’s Digital X-Ray Detector (DXD) line of medical imaging device products. The DXD software, developed in collaboration with , is LG’s first healthcare solution to utilize artificial intelligence. Paired with LG DXD, the advanced software provides a more convenient, more time-efficient way to generate and analyze X-ray images.
      Designed for large hospitals as well as private clinics*, LG’s DXD with X-ray acquisition software leverages advanced AI to help busy medical staff swiftly spot abnormalities in chest X-rays, reducing reading time by automatically flagging suspicious readings on the displayed image. Featuring VUNO’s clinically proven AI algorithm, LG DXD enables medical professionals to view original X-rays and AI-analyzed images at the same time, ideal for diagnosing pulmonary diseases such as tuberculosis, pneumonia or lung cancer. LG DXD can analyze X-rays for interstitial opacity, consolidation, pneumothorax, pleural effusion and nodule/mass then inform the medical provider of any abnormalities and provide an abnormality score with a colored heat map or contour that marks any lesions detected.
      LG is enhancing its range of high-quality medical solutions with the debut of a 14 x 17-inch wireless DXD with oxide panel that delivers high-resolution, low-dose images. The implementation of oxide and thicker cesium-iodide (CsI) scintillator and improved software means greater detective quantum efficiency (DQE) resulting in approximately 50 percent less radiation dosage. And with an IP68 rating, the new DXD is safe to use in dusty or wet conditions, while the eight hour battery life means easy portability and long usage times.
      “LG Digital X-Ray Detector is now even more powerful with the integration of VUNO’s AI technology,” said Jang Ik-hwan, senior vice president and head of the IT business unit of LG Electronics Business Solutions Company. “Our improved diagnostic tool will enable medical facilities to reduce incidences of misdiagnosis, provide faster analysis and assist healthcare professionals in detecting thoracic diseases early.”
      LG’s latest DXD medical solutions will be available starting in North America, followed by key markets in Europe and Asia.
