Linuxmint 13 Cinnamon 32 bit
Dell Inspiron 6400 laptop
Broadcom 440x 10/100 Integrated Controller (ethernet card)
________________________________________________________

I've had Linuxmint 13 Cinnamon installed and running on a Toshiba Canvio 750GB portable HD for months now. It used to work fine and the ethernet was easy to configure and use. I have no router; just an ethernet cable from my laptop to my ADSL modem.

I haven't booted from the portable HD for a while, so when I did boot from it this morning, I got the latest update, and that was a horrible mistake. I'll just talk about the ethernet problem here though.

I apparently lost all the info about my ethernet card (wireless card is disabled). Hope the following helps.

My ethernet connection still works fine everywhere but this Mint installation.

After being overwhelmed by all the help offered here

and after thinking about all the other problems the update caused, I just formatted the partition and installed Mint 14 Cinnamon. It's too soon to say much about how Nadia works on my portable HD.

I will say that using Linux makes me feel like an alpha tester.

We are alpha testers-- how can any distro ship with wired Ethernet completely broken, and keep it broken for over a year? I've been messing with the compat-wireless drivers with no success, though some users report that this fixes their missing wired Ethernet subsystem. http://www.linuxfoundation.org/collaborate/workgroups/networking/alx This is beyond stupid and unacceptable.

Some more information for my fellow sufferers: Wired Ethernet is so completely broken on Mint 13 that ifconfig does not see your wired interfaces, dmesg does not see them, and ethtool does not see them. You'll find them with lspci, your system BIOS, and this command:

inxi -N
Network: Card-1: Intel Ethernet Connection I217-V
Card-2: Realtek RTL8169 PCI Gigabit Ethernet Controller
Card-3: Realtek RTL8187 Wireless Adapter

These are well-supported GigE interfaces that worked perfectly until a Mint 13 update, and then it's as though they vanished completely.
