Wired Connection on Ubuntu/W7 Dual Setup


I have Ubuntu 12.04 and W7 Enterprise dual-loaded on my laptop. Ubuntu wants to connect automatically to wireless, but my house doesn't have wireless. The W7 side connects via the cable modem. But, Ubuntu will not connect via the cable modem. When I get rid of W7, will Ubuntu detect the wired connection?

W7 & Ubuntu are two different & separate O/Ss
if Ubuntu won't detect eth0 - then there is a config / setting error that is preventing that . . .

try to enable eth0 by right clicking on the 'net connection icon @ the top of the screen.

I've tried manually to create a new wired connection. I have the IP addresses for IPv4 ad IPv6, but I'm missing the info for "netmask" and "gateway". Where do I find this information?

It says "cannot find device 'eth0'".

That is really strange. Ethernet support is usually very good in Linux.
Try lspci and lshw

"lspci" gives me a laundry list of programs that are running; "lshw" gives me "you should run this as a super-user". How do I do that?

Have you tried running live-cd to see if it detects wired network?
