[Bug 1310798] Re: JMicron JMC250 ethernet: networking always disconnected
I can confirm that the JMC250 driver "jme version 1.0.8" which is part of Ubuntu 14.04 LTS does NOT support EEE (802.3az) at 1000 Mbit/s. It seems to support EEE ports at 100M, though. Evidence: When using a managed switch Zyxel GS1900-8, enabling the EEE at the switch port will prevent connection and the PC indicates that the ethernet cable is disconnected. When disabling EEE at that port, the PC connects immediately at 1000M. When using "unmanaged" switches (I tried TrendNet TEG-S50g), the only solution I have found is the same as above: force the connection to 100 Mbit/s. There is no way to disable EEE (which the vendor calls "Greennet"). sudo ethtool -s eth0 speed 100 duplex full. The Trendnet unmanaged switch works fine at 1000M with Windows 7. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310798 Title: JMicron JMC250 ethernet: networking always disconnected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1310798/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1310798] Re: JMicron JMC250 ethernet: networking always disconnected
Alex Cabal, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested exactly shown as: kernel-fixed-upstream-3.18-rc4 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

I'm more interested in what it looked like before the fix, I guess - in my case, the card was just never aliased to eth0 at all, and was marked DISABLED on boot.

Workaround over here. I don't know why, but the device just doesn't get named eth(x), it gets named p1p1 or similar, and doesn't get automatically entered into /etc/network/interfaces. I did lshw -c network on a new Trusty x64 Server install on my Gazelle Pro p9 laptop, and it showed the JMC250 as disabled, but with logical name p1p1. Did ifconfig p1p1 up ; dhclient p1p1 and connected to my network and got an address immediately.
