Slow on Ethernet Fast on Wifi

Hey,

 

I have a very strange problem. When i go tethered network (does not matter if with an directly connected LAN cable or with a USB-LAN adapter) i see two common problems: 

1. When using an Speed test like Speedtest.net i see a short burst in download speed followed by a steady decline. Normal up to 480mbits in the first 20% of the test and then slowly down to ~200 mbits to the end.

2. When i am using by onboard LAN i got only 20-30 mbits download.

Upload is just fine with 50mbits more or less constant.

I got an Msi MEG Z390 ACE with build in WIFI adapter, if i use the WIFI its fine and the speedtest climes up to 480-500 mbits and just stays there.
Now comes to funny part.

My pc is joined with my server on a splitter right before it gets to my router. My Server acts just fine with the expected 500/50 every time. I changed the cable from my pc to the splitter multiple times but it did not work.

So nether the USB-LAN nor the build in LAN port does bring me constant download speeds.

 

What in hell could be the problem?

 

EDIT:

Yes i did try turning off the WIFI Adapter when running the tests over LAN and vice version

hm no i dont think so as that would also affect my server.
 

Client  Server
    |          |

    ----------

         |

      Splitter

        |

      Router

The server performs fine.

The RJ45 to Usb is running on USB3.1 port (tried several with and without SS) and also supports USB3.1

When you say "splitter" do you mean some 2 to 1 abomination or an actual switch?

The pic is confusing.  Wouldn’t the splitter happen at the point the two machines connect rather than downstream of it?

Not a pro, not even very good.  I’m just old and have time currently.  Assuming I know a lot about computers can be a mistake.

Sory lost in translation.
Yes an actual Switch. An Netgear GS105Ev2

ok, phew, I've seen a few people actually using those $2 "splitters" so I wanted to eliminate that :)

You could also draw it like this:

 

Client  Server  Router

   ------ Switch ------

Aha.  That actually may help. Many switches  have multiple out ports but only one in.

Looked it up.  Just to check something that might be stupid, is the router cable in port 5?  If it isn’t, is the problem fixed if the router cable is in port 5?  If not all I got is there may be something up specifically with the client machine.

 

If this works btw someone at netgear needs to be poked somewhere delicate with something sharp.  Repeatedly.

Just for fun in tired to plug my client directly into the router. No Difference its something with the PC but i have no idea what i even could be anymore. I un/installed all sorts of drivers, disabled/Enabled Bluetooth, disabled/enabled WIFI, updated Bios, Updated Windows nothing. As soon as there is a god dam cable plugged into it, it behaves just strange.

I'm wondering, is there any sort of MSI software that might be causing an issue with regards to rate limiting or something?

MSI offers the KillerNetwork suite, currently uninstalled.

i might? have found the root of the problem. Super strange. Some weeks ago i played with the Windows Sandbox and therefore had installed the HyperV role on my Win10 Client. Yesterday i uninstalled HyperV, WindowsSandbox and the linux subsystem. For now there are no problems anymore.

 

super strange.

Nope again the problems are back.

I was about to shot images of an speedtest when i first disabled my Wired network adapter, then switched to WIFI made the shot and then switched back to Wired. After turning it off and on back again seem to be the solution.

I will write a Script to toggle my network adapter once in a while hoping that helps.
