Wireless working better than Wired mode - Router Troubleshoot

[JKL]

Hi!
My problem:
When I use the steam link on wireless mode, it works fine, like ok fine, not very fine. I can play games, and have no lag if the wireless network isnt overloaded (which happens, so it is no solution). When wired, the performance gets way worse, watching movies becomes annoying, playing games (I use dark souls as example) is not possible anymore.


My setup:
A Speedlink Router is wired through the house to a second TP Link router (https://www.amazon.de/TP-Link-TL-WR841N-Anschluss-GlasfaserModem-abnehmbare/dp/B001FWYGJS/ref=sr_1_4?ie=UTF8&qid=1519843403&sr=8-4&keywords=tp+link+wlan)
This one serves as a little switch for my pc and as much needed WLan extender (Brothers XBOX and PC, Tablet, couple smartphones). Plugged into that i have another ethernet cable (cat5 like the other) through the walls into my bedroom with my tv and the steamlink.
The TPlink router is setup as router, not as switch!


Stuff i tested already:

The ethernet cable from the tplink to the steamlink:
I basically streamed dark souls directly from my pc to the steam link, and it worked very fine. No frames dropped, perfect performance graph.

Internet connection:
Well my pc, the xbox, my brother's pc and the aformentioned tablet can all watch netflix at the same time 1080p 60fps no lags no problem. So the bandwith the router puts out seems ok. Fine i mean ;-)

Steamlink:
In addition to the stream test from my pc, i plugged the steam link directly into the speedlink (host router) to test performance and it worked wonderfully fine.

Problem Describtion:
So if i watch netflix f.e. I get lagspikes like every 30 seconds. Its not stuttering or lag, it is just freezeframe every 30s ~ish. If I start a game, dark souls f.e. the performance graphs go bonkers high (light blue one), then come to a rest when the menu is loaded. When going into the game, i have like 0.05fps coming to my tv. host pc fps is fine.
Performance graph from steam says "slow network" and only the light blue line goes up (pulling the red one up with it)


MY QUESTION:
So i figure the problem lies within my tplink router. I have actually 0 knowledge on routers and networks and stuff. Is my router too bad, or do i need to set it up in another way? It does connect to the steam link, and it streams stuff, but why this stuttering, increasing with the PCs load, i mean it gets worse as the pc gets more to do (=more to stream??)

Oh forgot to mention, audio never lags at all, even if i get like a 20 sec freezeframe, the audio keeps playing as if nothing stopped.

o i am not sure about the cables. any way to check now? And can the switch/router setting be the cause of my problem really? Ima try it tomorrow..

cat5 can work at gigabit speeds if the distances are about 20ft or shorter
cat5e is fine designed for gigabit
the pinout is the same, only diff is the ammount of crosstalk in the cable itself

the link only has a 10/100 port and does not support gigabit
its wifi can be faster since n starts at 150mb/s

more importantly are you using powerline adapters, those are crap and can create more lag and other devices can interfere easily with them

CAT 5e is 10/100/1000 rated ... with that many devics, CAT 5 might be clogging your network.

cat 6 is for 1000mbps 5e is for 100mbps max, good quality cables works up to 150-200 mbps but not stable cus they are not designed to work with so high bandwith

back to topic, there can be double NAT problems, set up one router as a bridge and setup second one properly

When streaming with the cable directly from my pc the performance was good. Steam link only supports 100mbits either, so even cat5 should be enough? I will try using the switch setup this evening and post the results. Thanks!
