Hi everyone,


I have a really weird problem and didn't manage to find the solution online yet so I'm posting here :


When I boot my PC, my network is slow : 150ish Mbps down / 1ish Mbps up and it feels all laggy specially in online games.


Here's an example of the speed when I boot my PC.

Everytime i feel this lag, I unplug my cat. 7 network cable and plug it back in and I feel so much improvement as you can see :

I don't want to unplug/replug my cable everytime, so I'm searching for a fix to this issue.


I have a 2.5Gbps down / 700Mbps up internet connexion from my ISP and my router is new and up to date.

I have a Realtek 2.5G network card in my PC and all its drivers are up-to-date from the constructor's website.

I forced 2.5Gbps full duplex on both sides but it doesn't seem to be a negociation problem.


Note : I'm a network engineer so you don't need to go easy on me :)


Additional notes : Yes everything is up to date, I tried to configure my network adapter settings in Windows, disabled green ethernet and every power-saving options, so far nothing seems to make a difference.


Specs :

  • Win 10 Pro up to date 07/10/2020
  • AMD Ryzen 5 3600
  • MSI B450 Gaming Plus Max
  • 16G RAM
  • 500Gb NVMe ssd where Windows is installed


Thanks in advance for your help :)
