I need to know what hardware I have and if it is working. Specifically,
every time I try to upgrade from 11.10 to 12.04, I lose my internet
connection and have to do a clean install of 11.10 when the connection
magically reappears. I have tried the upgrade page on the Software
Center and the Alternate CD(my computer won't accept the live CD)all the
while trying to select to keep my current settings. My driver is ne2k-
pci which is supposed to work with 12.04. Here is what I have on 11.10
which works and I forgot to run it when I installed 12.04.

Title:
Wired Network Disconnected after upgrade from Intrepid to Jaunty
Status in “network-manager” package in Ubuntu:
Confirmed
Bug description:
I'm using a DSL modem connected through an Ethernet port to connect to the
internet.
It used to work smoothly with Gutsy, Hardy and Intrepid but it hasn't been
set up correctly during the upgrade to Jaunty and the automatic installation of
Network Manager (I didn't use NM with previous versions).
Initially there were no connections defined in Network Manager and "Wired -
Device not managed" appeared in gray when right-clicking on the NM-applet icon.
I tried to solve it by changing managed=false to managed=true in
/etc/NetworkManager/nm-system-settings.conf
Thereafter Network Manager automatically detected eth1 and the DSL connection
but it's still unable to connect; I always receive the message "Wired Network
disconnected - you're now working offline" on a black background.
Hereafter some further information:
