Plex Remote (WAN) buffering and unable to play HD

Plex Media Server Plex Pass Betas
1

I posted this in regular forums without any answers before I realized there was a “PLEX PASS” section.

  So I need some help trying to get the most out of my PLEX when remote (over WAN). Local it's great! No buffering on any of my devices on the LAN wifi or wired. Problem is myself and my family always complain of buffering and having to lower quality way down to 2Mbps or some times below one to keep it from buffering. I have read a few things on the forum and run out of options. I read the logs but don't understand them to be honest. I did look for transcoding speeds (I run a i7-6700 rack mounted server with 16Gb of ram) and logs show over 5 and see throttled alot. I'm thinking my problem is not transcoding, but I'm open to ideas or a 2nd look at it.

Now bandwith would be obvious thing here and I pay for 100/10 threw spectrum cable. I have ran speed test and get more then that but I know that could be a fake so I have also ran iPerf3 from my work network (which is 200/15 cable internet) to home to test. I’ll post those pics below. I have a new cable modem at home an expensive docsis 3.1 SB8200 (but had these problems before) I also run ubiquiti unifi network at home in the same rack. USG router, USW 24 port POE switch. Should all be good to go unless I’m missing something in some settings somewhere.

 So My problem is no matter if I'm on my cell with LTE of 50mbps or at work or at a friends house (wifi or wired), I can only stream maybe up to 4mbps on a good day. usually less then 1Mbps though. With the new auto features in the andriod app or a web browser it will self lower to below 1mbps (0.7Mbps as we speak). I have tested fire tv's, apple phone, andriod phone and my web browser on a desktop at work. I'm figuring even on a bad day I should get a solid 7Mbps no problem streaming only 1 user at a time. Especially between my home computer and work computer which the limitation should be my 10Mbps upload speed at home. But As I type this at work playing a movie from the browser the auto feature is bouncing it between .7 and 3Mbps trying to keep it from buffering.

Hope someone can help.

Thanks,

Anyone with some help?

When experiencing the issue, what results do you get from running iperf in reverse mode (-R) from work?

Ok so not sure what it means, but I deffently see a speed issue from my phone running the -r reverse. Running from my work wifi or LTE both seem to show speed issues. Here is from my NOTE 8 phone connected to the wifi at work running -R back to home.
