PC gets 10mbps down from powerline, but laptop gets 50mbps?

Tp-link / Tl-wpa4530 kit

Specs: Windows 10, Ryzen 7 3Ghz/32gb RAM
Why does one computer connected to my powerline only get 10mbps download speed, while a laptop using the same ethernet cable gets 50mbps? I've tried using different cables and the result is the same, and the PC also experiences the same speed loss over wifi. The PC is newly built, if this makes any difference.
The powerline is the TP Link AV500 (TL-WPA4530 KIT)

Hope someone can help as I am at a loss!

Since the PC is newly built, go to the motherboard manufacture's web site and download and install the latest drivers, especially Chipset and anything related to internet, Wifi, NIC card (network), TCPIP, etc.

Thanks for the reply.
I just updated everything I could from the MSI website, including the BIOS, chipset, and Internet drivers. However, I'm still not getting the same speed as my laptop for some reason.

Speed test gives me this: http://www.speedtest.net/my-result/...

My laptop gets 50mbps+ download and 10mbps+ upload.

Any ideas?

Are the PC and laptop using the same power line , or are the powerlines connected in different locations ? Try re-testing using the same powerline location and compare again . Speeds on powerlines can vary greatly depending on the wiring within your house .

Check the properties of your ethernet adapter on the PC , check that there is no power saving options enabled , check that you select full duplex and 100mb speed or more

Make sure also that you are using Ethernet version B cables and not crossover , are your ethernet cables good , without broken cores ?

If suggestions on #3 also do not help, you may consider disabling inboard NIC and purchasing an NIC card for the desktop computer, they are not expensive and it may solve the problem. Remember to install the new driver for it and disable the original in Device Manager.
