Windows 10: cannot get gigabit ethernet to work

I have a Lenovo Alli n one PC AIO 520, it has a realtek gigabit LAN card, however i have tried to enable it every which way and i cannot get gigabit data transfers, i cannot exceed 10MBps, I have checked and rechecked the cabling, the router, the settings in windows and the router. Also checked the quality of the crimping on the RJ45 connecter. How can i troubleshoot this problem and find the source as to being one of the inbuilt LAN card or the network.



Appreciate the help.

Gigabit Ethernet not working

Hello, been a while since i've posted on here but i'm in kind of a bind. I just recently setup my house so that everything is gigabit, all CAT6 cables tested out for 1000mbps and routers and switches are all gig as well. However my main pc has a gig card built into it, a Marvell Yukon 88E8053 PCI-E Gigabit Ethernet Controller but it will only detect 100mbps and even if i force it to 1000mbps it still will only work at 100mbps.

When i do force 1000mbps the link lights are completely dead and it's acting as if there is no cable connected, but will work at 100mbps full duplex just fine... I'm at a loss here. *Bang Head :banghead:

If anyone has an idea as how to fix this it would be welcome *Smile

The driver version is 11.41.3.3 btw.

 

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.

 

Gigabit Ethernet Question

Nope, Gigabit Ethernet isn't as efficient as one might hope, as long as there aren't any other bandwidth hungry devices on the bus you're fine.
