I believe I was able to resolve this issue by installing the latest drivers for my network adapter.
The older driver was... driver: e1000e version: 1.0.2-k4 firmware-version: 0.3-0 The newer (working) driver is... driver: e1000e version: 1.2.17-NAPI firmware-version: 0.3-0 bus-info: 0000:00:19.0 For anyone else having this issue, here are the steps I used. (These instructions are included in a README file with the downloaded driver). $ sudo apt-get install ethtool # To find the name of the network adapter... $ lspci -v | grep Ethernet -A 1 $ ethtool -i eth0 # You can also reference http://www.intel.com/support/network/sb/cs-008441.htm # Navigate to http://sourceforge.net/projects/e1000 # Click on the "View all files" button. # Download the latest driver matching the output of ethtool -i eth0 # In my case this was e1000e stable | 1.2.17 $ cd [DOWNLOAD LOCATION] $ tar xvfz e1000e-1.2.17.tar.gz $ cd ./e1000e-1.2.17/src $ sudo modprobe -r e1000e # Note: rmmod e1000e is equivalent to modprobe -r e1000e $ sudo rm /lib/modules/`uname -r`/kernel/drivers/net/e1000e/e1000e.ko $ sudo make install $ sudo insmod /lib/modules/`uname -r`/kernel/drivers/net/e1000e/e1000e.ko $ sudo dpkg-reconfigure linux-image-`uname -r` # Reboot -- [Maverick] Auto eth0 not working after latest package upgrade https://bugs.launchpad.net/bugs/635475 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
