Hi All,
Im having a problem with wired connection, I searched in google and had no luck.
I made a video to show whats going on, someone knows how to fix that?
The command: "ip link", show the wired interface UP. The NetworkManager or Dhcp Clients (dhclient or dhcpcd) is acting like the cable is not connected, but if you watching the video, you can see that: modem Network light is ON, and at a given time (it's maybe starting systemctl services) the light is OFF. On Windows O.S the wired connection work with no problem.
Some information about environment:

I think the problem is ASPM, described in link:
https://bbs.archlinux.org/viewtopic.php?id=172432
https://bugs.launchpad.net/ubuntu/+sour … ug/1310798
But I do not have the solution yet

After alot of work, I figured out one way to make it work.
My device is "04:00.5 Ethernet controller: JMicron Technology Corp. JMC250 PCI Express Gigabit Ethernet Controller (rev 03)".
I downloaded driver source-code from official website of JMicron, and after some corrections I builded the driver.
Now I am searching for a way to provide this solution for Linux device drivers or for JMicron repository
