Hello,

Is there any way of installing an usb gigabit network adapter on a webos smart TV?  The builtin wired adapter is only 100mbps (on a 2000$+ TV, shame  on you LG!!!)  while the wifi (N) is very poor, with the router at 1m from TV it only gets half the bandwidth of the wired network. Anyway the wired network  maxes out near 100mbps but I need more bandwidth as I have 4k video content with bitrates grater than 100mbps which I cannot stream without stuttering to TV through XPLAY/PLEX. 

Kind regards,

After months of frustration and days of googling (is that a word?) I found this post and tried my luck. I am so happy to confirm this adapter also works on the 2018 models (in my case OLED65C8).
I even took the time to create an account to say thanks. So... THANKS!!!

After plugging in the device it takes some time for the tv to install (I think), after a while I (un)plugged the lan cable again, then the lights started flickering. Still the apps (youtube) say no connection, I had to reboot the tv first. As mentioned by others above, the TV shows no connection for LAN and Wifi, but it all works flawlessly 🙂

I downloaded the speedtest app, I get a more then reasonable 250Mbit up/down (I have 1GB up/down fiber connection). So I should be able to play all available 4K videos.

As for LAN content: 
I use the onboard LG Videoplayer, it plays almost everything without transcoding over DLNA.
I am able to play all my 4k HDR files right from my synology with Media Server App installed.
Also with Universal Media Server on my HTPC (with some .conf changes) everything plays perfect, incl. subtitles. 

Right now I am not at home, but later today I will try and play some of these reference files:

Exactly the same here. Thank you guys for the ideation and support.

For everyone in Germany, this is the one to order to get high bitrate content to work: 

 

Und um den anderen  deutschen Googlern zu helfen: LG TV 100mbit Ethernet LAN zu langsam, 4K UHD Inhalte mit hoher Bitrate abspielen, PLEX XPLAY

Ihr benötigt nur den hier von Amazon:  - einfach ans TV in die blaue USB-Buchse! Kurz warten bis der Treiber installiert ist, TV neustarten und es geht.

A proper lossless 4k/Atmos stream is 60 MB/s - 70 Mb/s, which is 460 - 560 mbps.

100mbps doesn't fit the bill, to stream 4k you need a 1gbps Ethernet connection.

I have already spoke to Samsung about this, even their latest and most expensive TV models only have a 100mbps connection yet they deliver 4k TV's, Atmos/DTS:X speaker sets.

They advised me to purchase their Samsung  UBD-M9500 or UBD-M9700 player to fix this problem because they should have a 1gbps, turns out even these players have a 100mbps connection.

Sony and LG are doing the same as Samsung.

Why sell 4k TV's and Atmos/DTS:X speaker sets without offering a product that can actually play the content without inserting a disc, now I have to start researching 3rd party products to be able to make use of these features.

Hi Paulus,

Thanks for the information, learn something new every day.

Hi,

Thanks for the interest 😀

This is a 4k/Atmos file straight from a Bluray disc:

spacer.png

Using HEVC compression, if it was H.264 the bitrate would be a little lower.

62,3Mb/s video + 4.2Mb/s audio = 66.5Mb/s which is 66.5mbps

That is a 4k/Atmos stream.

 

For some reason my devices cannot stream this without buffering and the entire house has Cat8 1gbps connections, my server has 2x 1gbps connections with LACP so it shouldn't be a problem.

How did you get this?

66.5Mb/s which is 532mbps

 

66.5 Mb/s is 66.5 Mb/s or Mbps

66.5 MB/s is 532 Mb/s

Mb is Megabit

MB is Megabyte

 

If you have a movie with 66 MB/s that is two hours long, it would occupy 464 GB. That would not fit on a Blu-ray disc.

Scratch the above....

For playback I switched to EMBY media server on my NAS with the corresponding Web-OS app, so no HTPC needed anymore. Took me a while to setup (disabling transcoding etc.) Finally managed to get it going, it works great. I haven't found a file it can't play. It even plays 80GB movies without stuttering, where I thought my NAS was not able to...  also Emby is great in finding subs.

To make a valid comparison, can u find out what files you can (not) play via:  ?

I am downloading  all h264 files between 80 mbps and 200 mbps now.

I can play 120mbps 4k perfectly fine. Without stuttering. Higher bitrates will cause buffering every x seconds

I had to plug in and out several times, waited for it to install (no message). Also try turning tv off and on a few times. If the lights start blinking there is communication...

I only have a light in the small blue led. Are you using the 3.0 slot?

So you have to do that every time ? Or does it just work after that first time ?

Yep its the 202013-BLK... it seems it might not get enough power or something. I have no lights in it besides the blue led. When i turn on the tv the network leds light up for a split second and then goes to nothing..  tried getting it in and out 100 times.

Plugged into the 3.0 slot

Super weird!

Better and more stable speeds now 🙂

Eureka it works!

I got exactly the same one, the Cable matters plug, initially I tested it wth my usb 2.0 dongle which failed (as in my post above) then I got the usb 3.0 dongle and it works like a charm! you can also connect via wifi for the other tv features to continue to work as well. This a massive fix for the TV!

How can usb ethernet be used for streaming and wifi for the rest?

first of all, thanks for finding compatible adapter for lg tv. i bought cable matters for my 55uh850v and it works perfect.

but i have a problem. i am using 3.0 port for now and sometimes tv's smartshare app doesnt show my pc as a dlna server. i have to click refresh button on top right and close the app then reopen it. sometimes i have to repeat it 2 or 3 times, then it works.

also i want to ask something. how you guys measure your lan speed on tv? is there any application for turning my pc as a server then using tv's web browser to connect to my pc and doing a lan speed test?

I have the cable matters and it works well for streaming (AND FAST). I did notice it won't work for downloading software updates though which is odd. I have to unplug it and download over wifi. Any ideas on that one?

Thanks.

I bought the Cable Matters RJ45 adapter as linked (https://www.amazon.de/Cable-Matters-3-0-Super-Netzwerkkabel-RJ45-Gigabit/dp/B00BBD7NFU/) for my LG B6, but I have not been able to get a connection. I plugged it into the USB port on the side, it says "Unknown device is connected", the adapter's blue light is on as well as the green ethernet light, but none of the TV apps get an internet connection. I have tried turning on and off the WiFi, plugging and unplugging, and restarting the TV but to no avail. I'd really like to be able to get the Gigabit ethernet to work, so I can stream high bitrate content to the Plex app. What am I doing wrong - has anyone been able to make it work on LG OLED55B6V?

I'm in the same boat with my LG 65UH7700 (bought in 2017). Seems to me that the USB adapter is getting the power it needs and is communicating with the network, but the OS doesn't seem to recognize that it can use that device for an internet connection. 

Any hope here?

Dear gents,

I can happily confirm that the Cable Matters adapter works flawlessly on the 2019 OLED55C9PLA model, plugged into a usb 2.0 port. LG decided to drop USB 3.0 but, even plugged into a USB 2.0 port, it performs better than the LAN port. With the network cable plugged into the LAN port, and a 40+ GB  BluRay movie, i would get buffering every 2 seconds (using DLNA with the SmartShare app installed on my PC). Plugged in the adapter into a 2.0 port, "unknown device connected" and everything works! Netflix, Prime, updates, etc. I do not have wifi configured, it shows wired disconnected and wireless disconnected.

Any recomendations which USB to Gigabit Ethernet adapter would work with an older LG TV model? (LG 43UJ630V-ZA)

I bought this specific one and didn't work on my LG Tv.

It worked on my PC and SteamLink just fine. Connection established normally.

Any help?

I don't know if it helps but these are the protocols that my TV support for Ethernet i guess. All of them 802.11.

And most of the USB to Ethernet adapters i checked are 802.3 or 802.2. I found an adapter in my country which has the protocols of my TV named on it.

It's brand is chinese named but doesn't really bother me? Should i go for this one adapter?

IEEE 802.11b, IEEE 802.11g, IEEE 802.11n
1000 Mbps

looks like your tv is from 2017, not that much old. my 55uh850v is from 2016.

try cable matters adapter on page 1. it works perfectly on my tv so it can work with your tv too like the others.

      LG Brings a New Lineup of Engaging Games to LG Smart TVs via Its Gaming Portal
      By News Reporter
      LG webOS-Powered TV Users Can Jump Into Immersive Gameplay, With Exclusive
      Single Titles, Games Playable With Magic Remote or LG Mobile Gamepad app

      SEOUL, Dec. 29, 2025 — LG Electronics (LG) is rolling out new games on its LG Gaming Portal,1 providing LG Smart TV users with a greater selection of titles, all playable directly on the screen without the need for additional devices. The expanded lineup demonstrates LG’s commitment to broadening its gaming ecosystem and evolving the Gaming Portal into the ultimate destination for compelling gaming experiences.
      LG continues to expand its Gaming Portal by offering more than 4,000 cloud-based games and 600 casual titles, presenting compelling gaming experiences directly on LG Smart TVs. By delivering elevated, device-free gaming, LG provides new and engaging ways to enjoy games on the large screens, brought by a growing ecosystem of studios and creators.
      Featuring dynamic choreography and familiar global hits, Just Dance Now2 is now available on LG Smart TVs running webOS 22 or later in the US, Australia, Sweden and Norway, with availability across Europe expected in the following weeks. Through LG’s collaboration with Ubisoft, users in supported markets can follow along with their favorite routines without the need for a console or additional controllers. Using the LG Magic Remote, users can enjoy dancing with friends or family through the remote control’s motion-sensing technology, which precisely mirrors their movements on screen for fluid and responsive gameplay.
      To bring more fun to every living room in the US, LG has partnered with Volley, the leading developer of voice AI games for smart TVs. Volley’s TV gaming lineup includes game show classics like Jeopardy! and original hits like Song Quiz, a guess-the-song music trivia game. Played by over 50 million people worldwide, Volley is pioneering a new era of voice-controlled entertainment in the living room.
      For those who are looking for the high-speed action of arcade racing, LG and Blacknut introduce Asphalt Legends Unite,3 an IP offering dynamic gameplay and exciting challenges to play with friends. Available for free with ads, players can unlock access to all cars and maps from the start, allowing them to race any supercar without in-game purchases. By simply pressing the directional keys on the remote, users in the US can join the race instantly and ride the momentum of every fast-paced moment.
      Another uplifting addition4 is My Little Puppy, a heartwarming adventure game published by Krafton and offered by Blacknut, in which players follow the story of a dog as he embarks on a journey of relationships, farewells and reunions. LG Smart TVs bring the lifelike details and vivid scenery of the game’s world to life on the big screen and subtly draw players into its emotional depth.
      With a growing ecosystem of games, such as Asphalt Legends Unite and My Little Puppy, LG has made it easier to also play with a smartphone through LG’s new Wi-Fi-based mobile gamepad app. LG Mobile Gamepad Wi-Fi,5 now available on both Android and iOS, allows smartphones to operate as controllers, enabling a seamless, hassle-free experience for supported games.
      Recognized at last year’s LG webOS Hackathon for their creativity and innovation, two award-winning games have now been added to the selection of titles on the LG Gaming Portal, allowing users to jump into these immersive game worlds optimized for LG Smart TVs. Quest of Sunflower by Couchplay, the Grand Prize winner, is an epic family adventure powered by stunning graphics and dynamic AI-generated storytelling. Signs of Magic by Lukas Klingsbo, the second-place winner, invites players to join the wizard Elowen on an exciting magical quest to defeat monsters. The LG Magic Remote functions like a magic wand, with gyroscopic sensors mapping out gestures as spells for playful interactions with monsters and magical items.
