Hi,

Just purchased an ASUS N550JK and experience the same problem. Wireless
works, but no network via ethernet.

Reverting to 3.13 kernel series would not be my preferred solution.
Seems more like a workaround than a fix.

Any ideas how to fix this on 14.04 running on 3.16 kernel?

Title:
  gigabit ethernet card  on ASUS N550JK not working at all

Status in linux package in Ubuntu:
  Expired

Bug description:
  
  The card detects link status, negotiates speed/duplex but no packets are sent or received. --- I verified the non-delivery using tcpdump on both machines connected to a local switch, I was watching for ARP (because it's an easy broadcast, ping a nonexistent IP) on the local end and the DHCP requests on the other. I only see packets that should be sent (DHCP requests, SMB queries, IPv6 announcements, etc), none of which reach the switch.

  The card is PCI ID 10ec:8168, rev 0c.

  I see "NETDEV WATCHDOG: eth0 (r8169): transmit queue 0 timed out in
  dmesg" , once, the full message below.

  rmmod/modprobe has no effect.

  Despite several reboots the card never worked.

  Everything else should be reported by "ubuntu-bug linux", but feel
  free to let me know if you need any information.
