I recently moved into a new house and have been configuring the internet there. It seems my desktop isn’t performing well with the new setup. At first, I checked if the issue was due to my Ubiquiti equipment, but other wired devices were getting the usual 500-600 Mbps while my desktop was only around 140-180 Mbps. This pattern remained consistent whether I connected the cable directly to the modem, the USG-3P router, or the switch with a 16-150W port. My desktop uses a Realtek GBE Family Controller and shows a confirmed 1.0 Gbps LAN connection on both the UniFi controller and the Windows 10 Network Adapter settings. I’ve tried several fixes: running ipconfig /flushdns, enabling/disabling DNS services, updating drivers via Realtek’s site, and using MSI Live Update. Interestingly, the actual upstream speed for this desktop is about 25Mbps, which adds to the confusion. I’m struggling to find a solution and need some advice.
This test aims to measure performance. Consider using iperf locally for better results.
I tested the setup quickly on fast, speedtest.net. After your advice, I used iperf with the laptop as the client and another machine as the server. The outcomes were consistent.

I discovered the issue later. My desktop required a winsock reset. I don’t recall the tcp/ip reset commands, but you can run netsh winsock reset in an elevated command prompt and then restart the system.
