100mbps rather than gigabit LAN (problem with e1000e)

[julien-dal-col]

Hi,

I have a Dell optiplex 755 running Ubuntu 13.04.

The integrated NIC is "Intel 82566DM Gigabit LAN"

"Connection Informations" gives me:
- "Driver: e1000e"
- "Speed: 100 Mb/s"

I guess there is a problem, It should say "1000Mb/s"... There is no 10/100 port in my whole LAN, only gigabit ones.

I don't know how to test wether my connection is actually limited to 100mbps or not...
I don't know how to fix this if the connection is endeed limited to 100mbps.

Any advice anyone?
Thank you very much in advance for your help.
Best,
-J-

[praseodym]

Also the switches (if any) and all cables support gigabit? Please show


sudo apt-get install ethtool
sudo ethtool eth0

[The Cog]

lshw -C network
should give useful information too.

Useful?

[sanderj]

The lshw output in line "configuration" says "speed=100Mbit/s". So there you have it.

My own output says: "speed=1Gbit/s"

So: check your cables and switch. Bad cables/connectors are a cause of throttling down to 100 or even 10 Mbps.

[julien-dal-col]

I did... :S
The NIC is connected to a brand new Linksys WUMC710 and the Ethernet cable was bundled with it (it's written "Cat5E patch cable" on the cable)...

I get a gigabit connection with the same device (linksys) and the same cable plugged into a different machine (running Win7 pro x64)...

[sanderj]

Is there Windows on you Dell optiplex 755? If so: is gigabit working under Windows?

Furthermore, you could do this:


# List current settings
sudo ethtool eth0
# are 1000baseT link modes listed?

# at your own risk (if 1000baseT is listed !):
# Re-negotiate speed
sudo ethtool -r eth0
# Force speed manually to gigabit
sudo ethtool -s eth0 speed 1000

What is the risk of forcing gigabit transfer rate?

One more info:

When I installed 13.04 the network card would not work ("device not managed"). I solved this following this tread:
http://www.techishare.com/linux/ubuntu-device-not-managed-problemsolved/

Could it be linked to my current problem?

[julien-dal-col]

do you think something may be wrong with the driver?

[praseodym]

Maybe. Try to update it according to this:

http://forum.ubuntuusers.de/topic/netzwerk-macht-probleme-unter-12/#post-5609442

The download link is there.

[julien-dal-col]

entschuldigungen sie bitte aber ich spreche nicht deutsch...

[julien-dal-col]

OK, so after a quick German self-learning ;) I did the following:
Downloaded http://downloadcenter.intel.com/confirm.aspx?httpDown=http://downloadmirror.intel.com/15817/eng/e1000e-2.5.4.tar.gz&lang=eng&Dwnldid=15817
from https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=15817

extracted the archive on the desktop.
Opened a terminal into the src directory of the downloaded folder
Ran the following:
make
sudo make install
sudo rmmod -f e1000e (this killed my connection)
sudo modprobe e1000e (this restored my connection)
sudo reboot

Result: no change :s

[praseodym]

Ok, lets check:


sudo ethtool eth0
dmesg | egrep 'eth0|e1'
ifconfig eth0
modinfo e1000e

[praseodym]

Did you really check all components (cable, router plug, switch, if any, etc.)? Only if all of them support Gigabit, it will work.

"Link detected: no" may be a hint for that (see above)

[julien-dal-col]

I double and even tripled checked...

[praseodym]

Try to deactivate the auto-negotiation:


sudo ethtool -s eth0 speed 100 autoneg off
After that try it with 1000

[julien-dal-col]

sudo ethtool -s eth0 speed 100 autoneg off

Didn't work... I still have to test this more thoroughly though...

However, I did the following:

- Install win7pro x64 on the optiplex 755 -> I get 1000mbps using the same hardware

- get a laptop configured with dual boot (WinXPsp3 & Ubuntu 12.04) -> 1000mbps on both OS... On ubuntu 12.04 the NIC driver was "tp3" not "e1000e" like for the optiplex 755

My best guess: e1000e is (a POS...) not working properly with my NIC
:s

[julien-dal-col]

is there any alternative to e1000e?

[praseodym]

Please check the product and vendor IDs:


lspci -nnk | grep -iA2 net

[julien-dal-col]

I installed:
XPEnology_DS3612xs_3211-repack-trantor-v1.2
on that hardware (dell optiplex 755).
It also uses e1000e as a NIC driver. Guess what? I get 100mbps connection.
It really seems something is wrong with e1000e

[julien-dal-col]

.

[julien-dal-col]

is it useful in any way?

[julien-dal-col]

Does anyone has the same problem? From what I could find e1000e is VERY widespread... Tons of network adapters use this driver... How come it limits bandwidth to 100mbps only in my case?

[julien-dal-col]

I read this:
http://lwn.net/Articles/278016/
My NIC is not PCIe, it is onboard... maybe I should try to use e1000 rather than e1000e?
How can I do that?

[julien-dal-col]

anyone?

[lazlo]

Same here! I have a Lenovo Thinkpad X201T with a intel NIC (82577LM). It worked with 1000baseT before. Now I only get 100baseT. Before I had this problem but i could solve it by reconnecting, disabling and reenabling networking or use of mii-tool.

I'm using ubuntu 13.04 with the 3.8.0-32 kernel.
