Hey,

I swapped laptops with my co-worker this afternoon but kept the harddrive to avoid installation of Kali Linux again. However when the "new laptop" boots up, I found wired connection is showing disconnected...I have the cable connected and tested. I also did following:
test@new-laptop:~$ ethtool -i eth0
driver: e1000e
version: 2.1.4-k
firmware-version: 0.3-0
bus-info: 0000:00:19.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no

I put the following configure into /etc/network/interfaces
auto eth0
allow-hotplug eth0
iface eth0 inet dhcp

and then run "sudo ifdown eth0; sudo ifup eth0". The output are like:
ifdown: interface eth0 not configured

I am going to upgrade the e1000e driver but donot know which one to download to use.

I googled the latest e1000e driver for linux and got top one as http://sourceforge.net/projects/e1000/. Not far down from list is the intel link. So which one should I use for kali linux? What is the difference?

Cause found: the stupid docking station. When docked, the ethernet works but no WIFI; when undocked, WIFI works but no ethernet....

LAN/WLAN Switch is disabled in BIOS but that does not help either way.

Still looking for solution...
