@Taylor first you need to edit /boot/grub/menu.lst text file as root, so run this on a terminal:
gksudo gedit /boot/grub/menu.lst
Then change the line starting with "# defoptions" as I explained above. Save the file and run this from a terminal:
sudo update-grub
Finally, reboot and the ethernet should work on batteries on first boot.
