Windows 10: Unstable Gigabit Wired Connection

Hi, I use my old PC as a Plex Media Server. The mainboard has a gigabit ethernet port (Realtek RTL8111GR) which worked with no problems until these last 3 weeks, which drops the connection to 100mbps or even 10mbps. When it's the latter (and more often happens lately), it struggles streaming high-resolution content, and I get a very low speed when I'm transferring files from other PCs through Samba. All peripherals support at least a gigabit connection (Archer C80 router, cat5e cables, and of course gigabit port on other PCs and TVs). I have tried to change the cable but no joy. I also have installed the latest driver from the mainboard page, Windows Update, and Realtek but the problem remains. The only solution is to unplug the cable, wait at least 1 minute then replug the cable. It often ends with a 100mbps connection (amber LED light) or going back to 10mbps (no light). It's getting harder to get a 1000mbps connection these last few days. Other devices in my home network work as they should. I can buy a gigabit PCI card but if there's any solution I can try first, or if there is anything I should know, please tell me. The PC specs are: - Windows 10 Pro 20H2 19042.985 - AMD A8-7650K - ASRock FM2A68M-DG3+ - 2x8GB DDR3 Memory - 120GB WD Green SSD - 4TB WD Red HDD - AMD RX550 4GB GPU Thanks in advance.

Yet another gigabit ethernet issue


Hello everyone,

Found this forum from my Google searches but couldn't find a similar issue.

I use ethernet cable to connect my laptop to a router. My router supports gigabit connection and the wiring of the house is cat 5e. Yet the connection is very unstable on my machine and I hardly see 1 Gbps negotiation. It is mostly auto negotiated as 100 Mbps. Read similar topics and saw that the problem often lies from the infrastructure. However, I did see 1 Gbit connection a couple of times within Windows 10 so I eliminated that out of the equation.

Here's what I have tried so far:

• I tried to set to 1 Gbps full duplex from auto negotiation in ethernet card settings. (I have onboard RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller) This did not change the negotiation speed, it remained on 100 Mbps.

• I tried booting to Ubuntu from an USB drive to check the connection and it was 1 Gbps and pretty stable; by that I mean it did not decrease the negotiation speed. Here you can see the hardware output from Ubuntu: Hardware output
• Strangely, after rebooting from Ubuntu to Windows 10, I saw 1 Gbps connection on ethernet status. However, this was temporary and switched automatically back to 100Mbps after some minutes. Plugging the ethernet cable out and back in multiple times sometimes helps to get 1 Gbit connection but this too is a temporary solution.

• I tried to update the drivers of my ethernet card from this page: Realtek PCIe GBE Family Controller | Realtek drivers download

Any tip would be appreciated. Thanks.
