Why does plex buffer in my local network?

So I have a small plex server, nothing much, I only use it for watching media on my personal desktop PC and occasionally I will stream movies to one of my Xbox Ones so I can enjoy the media in my living room or basement. It really bugs me, however, that when I do this, I get a poor experience when watching. As in, buffering every few minutes. My server has 32 gigs of DDR4 and a Ryzen 7 1700 processor, however, I’m pretty sure this shouldn’t matter as again, it’s my local network and it isn’t transcoding at all. In fact, to eliminate the buffering, I actually have to transcode down to 720p, and then I get a smooth experience. Why does this happen when I’m direct playing in my local network?

We have static IP and port forwarding set up on your server?

I thought I didn’t need that for my local network? Sorry, I’m quite new to all of this.

Still need it to play Direct Play for best results even in your own network. My friend was watching a movie and I noticed it was not clear and it was due to this issue, once we fixed the Remote Access issue, the movie was clear. My servers are running on a laptop that is five years old or on an Nvidia shield and as long as I have remote access enabled, I can direct play my videos and are clear.

Alright, I’ll look into it and get back to you. Thanks.

Are your Xbox devices connected to your network with Ethernet wire, or wifi? If wifi, then how strong is the signal and throughput? If you have a weak wifi signal, then the wifi may not be able to keep up with the data transfer rate needed for the higher res version of the movie, but can keep up with 720p.

FYI, I direct play and direct stream to my rokus without a static IP for my server. I do have remote access set up. Just my experience.

Wifi. I think the signal should be fine, and my wifi is 75 mb/s. Shouldn’t that enough for 1080p ~10mb/s video?

Best way to test is to get one of them hardwired and try a movie that fails now.

Yes, that should be enough. If you want to do additional verification, then you could wire in your Xbox and see if that fixes the problem. If it does that means likely wifi issues. If it doesn’t then the problem is elsewhere - perhaps per the other suggestions. It’s a good, easy test to try so you don’t beat yourself up looking elsewhere.

I don’t exactly have a 25 meter ethernet cable lying around

Seriously, you don’t? I do. :grinning:

Could you take your Xbox close to your network switch or router for the test, and hook it up to a small TV or computer monitor? It’s a very useful test, and could save you a ton of headaches looking for solutions elsewhere.

I will test it out later. Right now isn’t the best time.
