Two Files: "ifconfig" & "ifup eth0" [file name=ifconfig.jpg size=61095]http://www.linux.com/media/kunena/attachments/legacy/files/ifconfig.jpg[/file]
Try this to obtain an IP address from your DHCP server:
sudo dhclient eth0
If it didn't help try to "reset" the network manager state and reboot your computer.
sudo rm -f /var/lib/NetworkManager/NetworkManager.state
Ok, I guess I have to ask the obvious questions.
1. Are you trying to get the wireless or wired connection to work?
2. What Linux-based distro are you using?
3. Have you been using the sudo command before all command that we have recommended so they are run as the administrator?
4. Have you considered removing network manager and installing wicd?
Let me answer your questions as best as I can:
1. Wired Connection
2. Linux Mint 11
3. Yes, all was preceded by "sudo"
4. No. I have not tried removing "network Manager" & installing "wicd". I have no idea what this is.
