My ethernet connection is not working but it is detected by my computer

http://askubuntu.com – I'm setting up an old computer with ubuntu server 12.04. I wiped the drive and went through the installation fine but afterwards the ethernet would not work. It's physically connected to the router and the card is recognized by lspci(SiS 900) but it won't connect at all. I've plugged in and installed the drivers for a wifi adapter and it's worked with the same router. Just so you know I've turned it on and off plenty of times. Any help would be appreciated. (HowTos)

I set up ubuntu 12.04 server edition on an old computer and the ethernet is not connecting. It is recognized by ifconfig as eth0, and I think it worked during installation.

The driver is supported(SiS 900) and was recognized by lspci so the computer knows that it's there.

For example, I have a computer with a Network Inteface Card (NIC) which is an Ethernet card that is connected by Ethernet cables to a router. There is also another computer with a cable that is connected in another port of the router. This is a Belkin router operating over an Ethernet in the LAN.

Hi everyone!!!All was working pretty well on my Chakra system (installed one week ago, I'm a newbie on this distro). I rebooted my computer and after rebooting, no way to connect with ethernet ("Setting network address" endlessly).I used a usb wifi key and it perfectly works si it's really a problem with my ethernet card.

[ubuntu] auto connect ethernet 2 years 24 weeks ago

My issue here is unique. There are times when I need to turn the router off while the computer is on. When I turn the router back on, with the computer still on, I want the machine to sense a connection and connect. This does not happen. I'd have to go to the computer, click about and get it connected.

I have a computer that is connected to the internet via wifi. I then have a ethernet cable coming out from my wifi computer into another computer which has no wifi or place to plug into ethernet.

I have shared the wifi connection to the LAN port, and the computer successfully gets internet. But, on that computer I have a FTP server that I want the wifi network to be able to connect to.

So the setup looks like this:

There is a main WLAN-router/modem which is connected to the internet and serves the lower floor with WLAN. Now upstairs I have a second WLAN-router/modem (I will call it router two from now on). A normal ethernet cable is plugged in in router two in one of the four ethernet ports and also in one of the four ethernet ports in router one.

I am connected to the internet with an ethernet cable to a university network, no router involved. Yesterday the connection was working fine, usually after each boot I am prompted to enter a username and password to connect. Today my computer won't connect, it doesn't even get to the login screen.

Hello,

I have a Dell XPS M1210.

I have a Netgear router in my living room that has the wireless signal. It is connected to a Powerline plug that goes up to my bedroom. That is plugged into another router that is used as an ethernet hub. It's cables go into my PS3 and my server. The second router shows up as a hidden network on my laptop, and I can connect to it.
