Now a days i hear many people saying that the network manager in jaunty is buggy and they couldnt  connect to internet..So everyone out there before you make that statement please check the following :

—-> Gnome N/M auto-connects to a wired connection when it is plugged in. Does the network-manager icon have “Enable Networking” checked?

—->Normally for all the wired n wifi connections dhcpis used to assign an address…open a terminal and type:

sudo dhclient eth0
dhclient is the program that connects to a dhcp server on a network and asks for an ip address to be assigned to your computer. It is the most common method for assigning ip addresses on a lan.

For people who still cant get their network manager running,here are some alternatives.

You can use xnetcardconfig which is  a GUI program that can be installed and used via synaptic. Although you have to manually configure everytime you boot up,it is a good alternative…

Try installing wicd which is a nice tool for configuring wired and wireless networks..find it here http://www.ubuntugeek.com/wicd-wired-and-wireless-network-manager-for-ubuntu.html
