Plex Server Internet traffic problem

[oteros_manuel_gmail_com]

Hello,

I don’t know what else to look at … the moment I activate Plex Media Server on my computer, it affects my Internet traffic … this generates latencies and even micro cuts of the Internet connection. All installation is local, I only use it to watch movies that I have stored on a NAS on TV. I do not share anything with anyone. The moment I remove plex media server everything works fine again. I have it installed on an iMac and I have also installed it on a Synology NAS, same behavior, if I lift the Server on the iMac or on the NAS the exact same thing happens to me … can you help me?

Thank you very much.

Regardless of which device is running Plex Media Server, you experience internet problems on all/other devices on your network?

That’s … well, that’s something.

I see your ping examples. What’s your confidence level that these two things are connected?

Can you describe your network? What’s your router? Uh, maybe it hangs whenever there is UPnP or GDM traffic on your network.

I’m commenting partly to subscribe and follow this conversation. I’m quite curious too.

I have finally solved it, I also tried to install Plex Media Server on a RaspBerry Pi and the problem was the same, at the moment you stopped the Plex service, everything worked correctly so I completely ruled out problems in my local network.

My internet connection is 100 MB, Gg switches, CAT6 and a network of 4 computers at home, in all of them the same problem.

I have been able to disable UPnP and everything works fine now.

I don’t really understand what causes it but now everything is fine.

Glad that worked!

It sounds like your router was interrupting traffic when it got a UPnP request or query. That’s rather embarrassing for it.

Edit: I think I responded to a post that was removed?

UPnP is weirdly vilified. It isn’t fundamentally evil and can be done well.

But a lot of “consumer” equipment is pretty bad in general, and UPnP on top can make things worse.

This router that stops forwarding packets for almost a second? Oh gosh. Yes, turn it off, stop the bleeding. I’d be shopping for a different device based on that alone.

Not surprised at all
