Lag Spikes when remote streaming

[NetskyAU]

Hi guys,

I’ve finally come to the forums to see if some guru can seriously help me pin down this issue.

Whenever someone is streaming outside of the local network, I get enormous amounts of lag and ping spikes. I have an upload speed of 10mbps and bought the Plex Pass to limit bandwidth to see if that would fix the problem, it did not. I set the upload limit to 10 and streaming bitrate to 4mbps 720p and continued to lower the upload limit and bitrate and still no help. This only happens when streaming remotely, not internally.

I started reading the countless threads on this forum and others with people having the same issue. With all of them leading to a “dead thread” or “this worked for him but not for me”. I’ve tried multiple devices, I’ve turned off DLNA and tested, no change. I tried turning off UPnP, no change. I tried port forwarding, no change.

My next thought was, (PMS runs off a Raspberry Pi3) that the Pi cannot handle all the inner workings. So I installed PMS on my high end gaming PC to see if that would change anything, again, it did not.

I’m lost for hope and need assistance.

Cheers

Anyone? I can gather more information if people need.

That’s usually a sign that your router is overloaded or just has bad software. A reboot usually fixes this. Do you use WiFi for your connection to your router? Does your router support QoS?

Even if you set your Plex bandwidth to only 4 Mbps, streaming is not a continuous transmission of “only 4 Mbps”. The video is transmitted in segments of 4 Mbps video. While one segment is transmitted, all your available bandwidth is used. That’s what is causing your spikes. In average, the bandwidth requirement is 4 Mbps. Your router is responsible to treat all peers equally and to provide an equal share of your upstream to each peer.

I’m running a Netgear Nighthawk D7000. I did try QoS before. It helped a little but not much. The PMS is hard wired into the D7000 along with the testing PC.
