[ubuntu] Unable to Connect to Internet (Wired) in Ubuntu 10.04 LTS

http://ubuntuforums.org – I just setup dual boot with Ubuntu 10.04 LTS on my Windows 7 machine. I can connect to the internet just fine when I boot to Windows; however, when I boot to Ubuntu I can't connect to the internet via a wired connection. I went into the console window and typed ifconfig -a to see if my Ethernet card was visible but it wasn't. I also tried setting up a connection via Network Connections -> Wired to set up a wired connection but it's not taking. I can't seem to pin point the problem. My DHCP is setup on my Ubuntu system. Any ideas? (Hardware)

Stories similar to [ubuntu] Unable to Connect to Internet (Wired) in Ubuntu 10.04 LTS

Hello I am unable to connect to the Internet using a wired connection. I was able to use the wired network yesterday. But I had problems with the flash player, so had to reinstall Ubuntu again. I am able to connect to Internet using wireless connection. But I need to connect to the wired connection. I am using Ubuntu 10.

I'm rather new to Linux/Ubuntu and about to lose my religion figuring this one out.

I am unable to connect to the internet with ethernet in 10.04 64bit. Everything was working fine this morning, but when I booted up this evening, no connection.

In Network Connections, under the Wired tab, Auto eth0 reads Last Used: never. Also, Network Manager had created a new network, Wired Connection 1.

So, I have a wireless connection and I want to setup my linux box to share it with my LAN.

Sounds straight-forward, and I'd have no problem doing this setting up my router with DD-WRT as a bridge. However, the WiFi connection is an ad-hoc network using ICS through my Windows Mobile Verizon phone and the router won't connect to it.

I am having a problem connecting to wired connection from router. I used to have 11.10 where I tried to establish DSL connection. I tried it doing through the terminal using some pppoeconf commands.

When I reboot my system, under the Ubuntu loading sign, I saw messages like configuring network; wait 60 seconds more for connection, etc.

Then after 2-3 minutes, Ubuntu home screen appears.

I have just installed ubuntu 10.04 using the wubi installer to dual-boot my machine. Under ubuntu, I am not able to connect to the internet or my router. Everything works fine under windows. I have tried to find relevant information in the forums, but nothing seems to work for me. I have tried disabling ipv6, setting a static ip, but no go.

The wired internet connection by default is configured properly in Ubuntu installation. We can directly dial-up via sudo pppoeconf, or connect to a cable which already on internet.

I have a dell latitude 2100 running ubuntu 11.1. Wireless internet works fine on it but wired connections do not. When I plug a ethernet cord in, it keeps on saying wired connection connected followed by disconnected. When I check the ethernet connection in the network part of system settings, it also keeps rapidly changing to on/off.

Hey guys,

Hopefully this is a quick and simple question.

I'm running F17 and I need to connect my machine to a local group of computers tied together with a network switch.

I'm having trouble to connect my Ubuntu 11.10 to internet through ethernet. I installed a router to get Wi-Fi and now (by a wired connection) I can't have internet with ubuntu (but I can with Windows 7).
