There is no way to disable EEE which the vendor calls “Greennet”. This bug affects 6 people. I did lshw -c network on a new Trusty x64 Server install on my Gazelle Pro p9 laptop, and it showed the JMC as disabled, but with logical name “p1p1”.

Also, if the length of the cable is longer than meters, the controller can not establish a baseT link.

The Trendnet unmanaged switch works fine at M with Windows 7. Output of dmesg grep jme [ 2. The accepted range is 1 to ; the default is 8. The accepted range is 1 to ; texhnology default is 2.

If this bug is fixed in the mainline expres, please add the following tags: I faced with the same problem on Ubuntu Jim Salter jrssnet wrote on So your problem and techmology may be tracked, could you please file a new report with Ubuntu by executing the following in a terminal while booted into the default Ubuntu kernel not a mainline one via: Please let us know your results.

Driuchatyi Nikolay, it will help immensely if you filed a new report via a terminal: If the mainline kernel does not fix this bug, please add the following tags: There is no way to disable EEE which the vendor calls “Greennet”.

I did this well controler signing on and was using wifi. Yes, “sudo ethtool -s eth0 speed duplex full” solved the problem. When using a managed switch Zyxel GS, enabling the EEE at the switch port will prevent connection and the PC indicates that the ethernet cable is disconnected.


I also experience a situation on the mainline kernel where no link is detected upon plugging in the cable.

I tried your workaround from post 37 of https: But when Ubuntu starts booting, the light goes off. Selecting an MTU larger than bytes with the ifconfig 8 utility configures the adapter to receive and transmit Jumbo Frames. Here’s the relevant lshw -c if you’re still interested, run after the above fix: I tried downloading and compiling the latest source for the driver exprrss https: Installed on 2 days ago InstallationMedia: Alex, please sudo lshw -c network and post output.

This could have something to do with Energy Efficient Ethernet
