Failing network adapter

Claus BrochChristensen

Hi,

I am having issues with my internal network adapter (eth0 - Intel 82579LM Gbit adapter).

Test case:

  1. Start a speedtest.net session
    1. This will start normally and the fail
  2. The network adapter will stop responding to ping
  3. Found the following in the kernel log:

    Hi Claus,

    I checked #7.8 in Rulz and found that the 82574 is not good, but I don't know about your adapter.  Is this a new installation, one that you recently upgraded or ???

    Cheers - Bob

    Hi,

    Well I saw that myself, but since it isn't the same I hoped to be safe.

    The system is newly built on a more powerful pc that should be able to handle my faster internet lines of 300  Mbit. The other adapters are a dual port pcie  ( Intel 82571EB Gbit adapter).

    The configuration was restored from my old system.

    I will try to change the adapter. Thanks
