Hi, I'm using the latest build (JUL-2020) for Tp-Link WDR4900v1 on a 1000/500 Mbps fiber internet connection. Any ideea why Windows clients have lower Download/Upload speed than Linux clients? The minimum configuration for the PC is: I5-8300/i7-8700, 8/16GB RAM and 256/512 nvme. Not using SQM QOS, and SFE flow offloading is enabled.

1Gb

A few things you can check

  1. Congestion Control inside netsh https://techcommunity.microsoft.com/t5/networking-blog/core-network-stack-features-in-the-creators-update-for-windows/ba-p/339676
  2. Windows Device Driver I have experience before certain realtek driver doesn't do gigabit data transfer but others do

After days of tuning I found "SG TCP Optimizer", which helped me a lot. Still don't get as much speed as on Linux, but now I can reach 800 Mbps upload / 450 Mbps download on Windows. I thought it was time to change the router, but I'll keep it for a while.

Tnx
