Theoretical 1gbps home network.. lagging

So my network is theoretically about 1gbps in lan, and 750mbps in wifi.

I run a Plex Media Server, and i recently jumped up to streaming 4k content locally. The problem I now have is its lagging.

First here is my network map

Fios Quantum Router, connected via ethernet (not copper). This broadcasts a single SSID, at both 2.4 and 5.0. All lan ports are 1gbps, wifi is rated at 750mbps, atleast in throughput.

Samsung connect pro (smartthings hub). This is a Wifi access point, which is directly plugged into the Quantum via cat5e. Its wifi capabilities are 1gbps, but since fios is 750mbps, than its capped there in a bottleneck. The samsung connect is ziptied to the tv wall mount, directly behind the tv, less than a 6 inches from the tv.

My pc recently built has a i7 6700K (or 6600k) either way the Z170 Mobos that have the chipset are all 1gbps. The pc is the plex media server.

The tv is sony bravia 900E, which has a 100mbps lan connection, and wifi is up to AC (cant find direct specs) when running a speedtest on the bravia, lan results in 80ish download speed, and wifi results in 60ish. Keep in mind i also have a father in law streaming fuboTV.

My Wan speeds are 100/100, but this shouldnt matter.

As for actual cables, The quantum gets ethernet from the fiber modem outside. Which than sends out cat5e to a philips hue, than goes to 3 wall ports, which runs a line to the pms in the bedroom, and 2 ports behind the tv, for the samsung connect & ps4. The connect than connects to the tv. I try toggleing to wifi back and fourth.

1. How can i test the throughput on my network, to find where exactly my lag is happening.

2. How can i monitor all traffic on my network, like i want to see which device is pulling how much data, and from where (outside or inside network). I want to see if maybe there is a single component like a port that is bottlenecking me, or maybe a download on the pc, or the streaming of fuboTV.

I have 3 theories atm.

1. The wifi and Lan speeds of the bravia TV are complete and utter crap, and since the bitrate average of these movies are upwards of 44Mbps (cant get up to 120Mbps) Im thinking thats where my lag is happening..

2. The bravias SoC (integrated cpu) is not strong enough to directly play such large media files.

3. Somewhere in my local network I am getting a bottleneck, whether its the PMS itself capped at 100Mbps, or the tv, a port, a stupid setting on the quantum.

What is a philips hue, and what does it do?

By lag, do you mean it pauses/skips during regular playback?

I would try ensuring a completely wired connection from the PC to the TV, and see if that improves anything.

Also, as an FYI, when a router says its wifi is X Mbps, that usually means that X is the theoretical total bandwidth it can handle across all connections (i.e. those values assume you have multiple devices connected, on both 5 GHz and 2.4 GHz bands if available). The max theoretical bandwidth to a single device will usually be lower, and depend on the Wifi capabilities of the device. And of course the real world performance will always be lower than theoretical values.

Also, if your samsung AP is connected to your router over ethernet, then the router's wifi speeds have no effect on the AP's wifi speeds.

Phillips Hue, more specifically the Phillips Hue Bridge, is the hub that controls all the Phillips Hue smart lights in the house, just the light bulbs which are RGB, and dimmable, + the LED strips and the Switches as well. Its a smart home addition basically. Doesnt take up any bandwidth.

I am aware of theoretical bandwidth.

As it turned out, it was the Sony bravias weak wifi chip & the 10/100 port causing the buffering to happen. I went with the Nvidia Shield, all is good.

The bitrates on the movies I was streaming over my network were reaching peaks of 100mbps and above, while the tv was struggling to reach speeds of 86mbps.
