Hi folks,

I've read about people using USB Gigabit Ethernet adapters with their LG TVs to get around 100mbit ethernet performance issues when accessing my Plex library.

I've just purchased this adapter which several posts on here and indeed several review comments say should work.... but it doesn't.

My LG TV is a 55NANO866NA running WebOS 03.221.05

I know that the dongle wont show up in the menu, but its showing a link light, the activity light flashes every now and again, but the TV isn't able to get on the network.

It's connected directly to my Unifi UDM (running latest software, tried several ports). The UDM is showing a link is active, and that its a 1Gbps.

I've tried powering off and back on the TV (pull power lead out, wait a minute, etc) and tried all 3 USB ports on the back of the tv.

What am I missing?

The TV has 3x USB 2.0 ports according to the specs I've seen. Can you check this yourself to confirm?

USB 2.0 has a theoretical max transfer speed of 480mbps. That's the equivalent of Ethernet at 60MB/s. That's slower than Ethernet 10/100 which maxes out at 100MB/s

Fast Ethernet is faster than your Ethernet-to-USB adapter not because of the adapter speed, but because of the transfer speed to USB 2.0. Even if you fix the connectivity issue, you're still worse off with the adapter+USB combo than you are with 10/100 Fast Ethernet.

If the Plex-sourced files are too large to transmit over 10/100 Fast Ethernet then you need some other solution to either get around this or to shrink the file size. The two solutions that come to mind are either some media player box with Gigabit Ethernet that will work with Plex and support the features of your file rips if they carry HDR etc. That, or some on-the-fly file resizing as the media is streaming from the NAS. That could be quite expensive though.
 
Just bite the bullet and buy an Nvidia Shield.

It comes with Plex installed and you can stream full UHD Blu-ray rips from your Plex server in Dolby Atmos and Dolby Vision. Without the need for any transcoding.

All other solutions are comprise in one or another. The Nvidia Shield just works.

That should be 100Mb/s which is around 12MB's a second.

This seems like a sensible idea.... I will investigate.
