<SOLVED> Stuck at 10Mbps limit instead of 100Mbps

Post by kieto »

Hi everyone! I could use some help, please. I've been looking/asking for hours and still no solution.

I have a dual boot win/linux and on windows. I'm using an Intel 82562V-2 10/100 ethernet controller with an e1000e driver. My NIC speed on Windows XP is 100Mb/s. On linux the NIC speed is set to 10Mb/s as you can see here:

Also, I checked with [url]http://www.speedtest.net[/url] and it gives me a download speed of about 80Mb/s on windows, and only 8Mb/s on linux. So it's not an ethernet cable problem; some suggest the linux driver isn't working properly.

On linux mint, when I try to change the NIC's speed with:

Code: Select all

sudo ethtool -s eth0 speed 100 duplex full
it seems to switch the NIC's Speed from 10 to 100Mb/s, but the wired connection stops working. If I revert it by typing:

Code: Select all

sudo ethtool -s eth0 speed 10 duplex full
the connection comes back.

I also tried to repeat the last steps while upgrading the kernel from 3.5.0-17-generic to 3.11.0-031100-generic, but no improvement at all.

Next thing I tried was typing:

Code: Select all

sudo ethtool -s eth0 autoneg on advertise 0x0F
ethtool eth0

to go from this [url]http://pastebin.com/vFeMYU6R[/url] to this [url]http://pastebin.com/KbjBqATf[/url]. Then I tried:

Code: Select all

sudo ethtool -r eth0

but it's still stuck at 10mbps.

When typing

Code: Select all

sudo ethtool -s eth0 speed 100 duplex full autoneg off
NIC speed seems to switch to 100Mb/s (as you can see here [url]http://pastebin.com/L39QYCu3[/url]), but [url]http://speedtest.net[/url] shows an even reduced Speed: 5Mb/s.

So, I'm out of ideas by now. Does anyone know what else should I try in order to set the NIC speed succesfully at 100Mbps ?

Re: [Ethernet 82562V-2] Stuck at 10Mbps limit instead of 100

Update:

So... I found a temporary solution. If I just unplug and plug the cable, the speed goes up to 100Mb/s. When I reboot the system (or restart the ethernet connection with commands ifdown/ifup), it goes back to 10Mb/s. I've tried this with 3 different ethernet cables.

So the only solution I found is to restart physically the connection every time I turn on my computer.
