Intel 82578DC Gigabit only uses 10Mb

English Hardware
#1

Have a new machine, installed OpenSusE 11.2 on it.

Only one problem: the network will only works with 10Mb. :frowning:
Changing it with ethtool does NOT work.

Has someone a solution ???

Here some info:

after some second the prompt comes back, but “ethtool eth0” gives same result as above

Hello,

I am running opensuse 11.2 on an intel dp55sb board which uses the 82578DC controller as well – I also had this problem.

The problem you are having is well documented on Intel’s tech support forums (under windows and linux) – problem was easily remedied by downloading, building and installing Intel’s latest driver.

Here is my info (I am on a 100Mb network so I am only connected 100Mb):

Same problem too.

You wouldn’t by chance have a link.

I’m here but couldn’t find much.

Thank you.

Problem fixed. Speed now 1000Mb/s.

Info:
https://bugzilla.novell.com/show_bug.cgi?id=576970

New e1000e driver (follow readme.txt):
Network Adapter Driver for PCI-E Gigabit Network Connections under Linux](http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=15817)

Need to install from OpenSUSE: kernel-desktop, kernel-desktop-base, kernel-desktop-devel

I sure wish the OpenSUSE search was more refined.

I have built kernel modules from the current intel-driver, which are available
Index of /repositories/home:/weberho:/kernel-modules for
most recent OSS and SLES flavours.
The module runs nicely on my OSS 11.2 x86_64 system.
