LAN speed needed for Smart TV Plex App, 4k, 1080p etc

Hi

I have a new Samsung Smart TV with the connect box, the WiFi supports 5Ghz but the ethernet LAN port is only 100meg.

Is a 100 meg ethernet connection enough to stream 30gig file size 4k films? I am also talking about LAN home streaming from my Plex server (not remote streaming)

I cant connect my TV to the WiFi as the connect box is in a cupboard which means the 5G WiFi is weak meaning it flips to 2.4ghz which can cause playback issues(my router doesn’t support 2.4/5ghz separation), I also would prefer to use a hard wired connection for the sake of reliability, stability.

I have streamed the 30gig file all okay but is it at its limits with 100meg? What I don’t want it it to ‘become’ unstable and if really a must I will relocate the connect box to gain a better wifi signal and use that instead, devices connect to my 5ghz wifi 800Mbps+ when a decent signal is present

My LAN network itself is all CAT6 so not a problem with that and the speed reported by the TV connected to the 100meg LAN is 65-75meg

Almost certainly. It needs the 4K HDR remuxes to push the connection to the limit.
However there’s a couple of threads on here about how well those USB to gigabit adaptors work for around £10.

See this thread for two examples

Sorry mate I don’t fully understand your reply, are you saying 100meg is enough to stream 4k HDR (All my 4k streams direct play to my Samsung Plex app no transcoding going on)?

Also what does ‘It needs the 4K HDR remuxes to push the connection to the limit’ mean?

All my 4k streams direct play to my Samsung Plex app no transcoding going on.

He’s mentioned that to overcome the 4k issues with steaming adding the dongle mentioned will help.

I found the 100meg NIC on the TV just not good enough for proper 4k streaming.

Sorry…to be clearer,
You should be totally fine at that file size. The bit rate will not be huge.
The comment about the remuxes is more to do with the bitrate of those files. They tend to be 50-80GB in size. The bitrate can often be extremely high. At least 2-3 times the bitrate of the files you are talking about. It generally takes those to really push the limits of the network port in the tv.

TL;DR

You should be fine but if you have issues take a look at those adapters in the earlier post.

Thanks mate and thanks for explaining.

I am not having problems, but am trying to understand the limits of a 100meg LAN connection, which HitsVille-UK has kindly explained to me. What I don’t want to do is have my PLEX client using a 100meg LAN which is on the edge of its limits which then starts playing up as family members will just get annoyed with it and me!!!, which by all accounts it doesn’t seem to be so all is well. Network utilisation seems to be peaking at 47meg and settles down to approx. 25meg when playing the 30gig 4k HDR file, personally I don’t feel the need for bigger 4k files as my TV is only 49inch, I can barely tell the difference between Netflix 4k and HD versions as it is.

The adaptor solution may or may not work on my Samsung connect box and I have read reports of this method dropping out, freezing so I don’t really want to waste £10 on something I don’t need at the moment that may actually cause other problems and would rather wait until I bit more information is available from people using them.

Understood. Was just sharing my experience of playing large 4k files across network using LG NIC which didn’t seem to cope.

Agreed there’s no point in spending cash unnecessarily unless you have a problem.

I have no issues with the 100meg Ethernet connection on my LG TV - direct play 4K HDR, v.large file size sizes (>30Gb).

It’s more about the bitrate of the file and how well it’s been encoded. Depending on how you encode your files you may get large bitrate spikes. That’s what I found with mine at least, but I try and rip them with no compression so the file sizes are quite large as are the bitrates.

This solution may not be for everyone, but for me certainly it has transformed how I consume my 4K media.

Basically I started to see some random buffering issues with 4k movies via the 100meg LAN so tried a USB to 1000meg LAN adaptor on my Samsung Frame 2018 model with the connect box, short of it, it doesn’t work, not recognised, so I borrowed a friends TP-Link adaptor, that doesn’t work either, so my conclusion is, the adaptor solution only works on specific TV’s.
I went down the MESH wifi route and relocated my connect box (its not really where I want it but better than a flaky connection) as my router can be expanded using extra dish’s, bingo all seems well and connecting at over 300meg. I also noticed some bad packets on my managed switch so changed out some CAT6 patch leads, errors have now ceased so I may try the 100meg LAN again.

My 2016 Samsung couldn’t play 4K remuxes with a bitrate of over approximately 55-60Mbps. If your 4K movies are around 30GB in size, their bitrate will likely be much lower.

Switching to 5Ghz wifi solved the problem (my TV is right next to the router) but I’m aware you can’t do that.

Keep in mind that bitrate can be variable, meaning that although the average bitrate of file might be 60Mbps it could burst to above 100Mbps in busy scenes.

You may be right. I haven’t seen anything (but admittedly haven’t looked too hard) that suggests the adaptors work on anything beyond LG TV’s.
