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.
