WiFi ok but slow LAN buffer city

I’ve been trying to get better performance in my bedroom for weeks trying various setups and devices ranging from FIRE TV, to google TV, NVIDIA sheild, I mini intel PC etc etc.

I have two main issues:

  1. if I use wifi movies play straight away, if I use any sort of wired lan setup they bugger for ages and in most circumstances wont play at all regardless of settings.

  2. Plex wont play any 4k HDR movies over 3mbs transcoded even though my WIFI is a consisntent 15/mb/s, it buffers all the time and tells me the connection is not fast enough or something, when I check my tanscoding PC states it not even using 40% cpu (sadly it has an AMD card so only 10% of transcoding is happening on that)

So I should be be able to get at least 1080p @ 8mb/sec but I cant even get that. This is why I decided to lan up my bedroom but literally nothing worked, I just got constant buffering, this is something that should just work, it failed to work with the following devices:

Galaxy S21 through dex dock
fire TV using LAN connected by OTG and usb ethernet dongle
surface pro with lan via usb ethernet dongle
hp elite desk g2 directly connected by lan.
LG 4k TV connect by LAN using plex app.

All worked for other apps fine like VLC and KODI over the network but plex was just buffer buffer buffer, is there a major bug with Plex and LAN connections?

Finally, when can we see some AMD love, It pretty incredible AMD cards still aren’t properly supported for transcoding rendering them almost 90% useless, how hard can this be?

Can you describe or illustrate your home network and identify what network devices you are using?

nothing special, ryzen 3600 PC / amd 5700gpu, gigabit ethernet, 4 port gigabit switch connected to my virgin superhub 3, 5 meter cable to my bedroom.

If I understand you correctly

PC <-> Switch <-> Router

The cable that runs to your bedroom is it connected to the the switch or the router?

transcoding plex server PC is connected directly to router, switch is connected to router, cable to bedroom is connected to switch.

Can you connect the PC to the switch and test?

I gave up with this and decided to get a gigabit WIFI access point, sadly i’m having some issues with that too. I’m getting a sustained 15-20 mb/sec on that but when I set the transcoder to only 1080p 8 meg/sec i’m still getting drop outs stating my connection is not fast enough to play this content, it clearly is, whats going on here?

could it be that as i’m using an AMD card the transcoder isnt pushing the data fast enough for an 8mb connection, if I drop to 720p 3 mb its fine all day, there is something very odd going on here and its really frustating.

I’m simply trying to achieve 1080p to my projector for my 4kHDR movies, my network is easily fast enough to play these outright as my Galaxy S22 can play them as is untranscoded accross this network, why cant plex transcoding handle these at 1080p?

Q: Are trying to hardware transcode HDR content to an SDR client?

hi, yes

The HDR conversion is pretty hefty. Esp if the source is H265 HDR

Is it possible to test the same film in 4K SDR format?
This way you can check to see if the issue is the PC struggling to transcode the colourspace to BT.709.

It’s a shame you can’t get the bandwidth in your home network. The Shield should play 4K HDR at full bitrate. No transcode, no problem.

Thanks for the reply, I did try the sheild but I was getting some minor glitches even connected via lan so I sacked that off, the only thing i’ve had a reliable watchin experience on it my surface pro, even by WIFI so I dont think its bandwidth, I think its transcoding, I dont think it works very well yet for HDR h265, I think it tells me my connection isnt fast enough but I suspect its the transcoder which isnt pushing out frames fast enough, even though its only using about 30% CPU when playing these movies. - if I can play these files full fat accross the network using MPC-BE tone mapping to SDR with no issues it has to be the crappy transcoder.

I just tried the new HTPC app on my surface pro, this was pretty unwatchable, choppy as hell, buttery smooth on MPC-BE and KODI, starting to regret my lifetime purchase deeply.
