2.5Gb network card issue

Hello,

To make the most of my fiber subscription, I installed a tplink tx201 2.5gb network card in the pci-e4 slot of my motherboard (msi b550 gaming plus),

The problem is that it only works at 1Gb, I'm on Windows 11, and I've installed the latest drivers I downloaded from the tplink website (the same ones found on the realtek site).

I don't think it's a driver issue because as soon as I start the PC, even before booting into the OS, only the 1Gb LED on the network card lights up.

Could you please provide a solution or some suggestions to try to resolve my issue?

Thank you

Hello,

Before getting suitable answers, I would need your connection environment. The model of the box, the PC is connected directly to the box on port 2.5, the PC goes through wall sockets, through a switch, the type of Ethernet cables, ...

There is no port 2.5, is there?

Afterwards, I don't know her well.

The problem came from there, there are 4 Ethernet ports (yellow) and one 10gb/2.5gb port (black).

The card works well at 2.5gb now but the speed has barely increased, I went from 900mbps to 970.... according to Bouygues' technical service, I should be around 1800...

He was connected to an ethernet port but not to the 10/2.5Gb.

Now the card is working well at 2.5Gb but the speed has barely increased.

Hello,

I tried using a bootable USB drive (hirenboot) and the tests are completely different, I'm at 1950mbps compared to 900 on Windows 11....

If you have any ideas I'm all ears..

Problem solved!!

I used TCP Optimizer found on the Malekal site.

https://www.malekal.com/optimiser-connexions-windows-10/#Optimiser_les_connexions_sur_Windows_1011

The speed has increased to 1950mbps.

Thank you for your help!

Hello,

This "TCP optimizer" from Malekal is interesting. What can cause TCP to be suboptimal without this software? Brupala will surely have the answer! Just wanted to say hi to him :)

OK, thanks for the feedback,

I'm wondering what messes up the Windows settings to the point that we have to use a tool from another era to restore the normal values.

Because TCP Optimizer was useful when we had slow connections, but on high-speed links like today, it's normally useless, unless some junk is messing with the Windows parameters.

Maybe the default settings are not optimal for the specific case of the speed test.

It's difficult to have settings that are optimal for all uses and situations (network quality, frame loss, ...).

What is certain is that with Linux, you don't have these problems; moreover, the TCP parameters are dynamically adjusted according to the transmission conditions (speed of acknowledgments, number of retransmissions). Furthermore, in a transmission, there are two of us, and the server's configuration is more important than the client's, and most servers on the internet run on Linux.

Additionally, many downloads today no longer use TCP but things like QUIC (not speedtest). It should also be noted that a speedtest consists of several (often 3) TCP connections in parallel on the same server, so if one gets slightly blocked due to packet loss, the others continue to function.
