1135982 2010-09-10 02:50:00 I have Ubuntu 10.04 installed on a HP PC. I can get no internet connection thru the wired ethernet. Googling gives many suggested solutions, none of which have worked.

Can someone here help me to get it working?

1135983 2010-09-10 03:00:00 Might be a good idea if you also posted the model of the machine nedkelly (9059)
1135984 2010-09-10 04:01:00 Could you please post the following (these are commands that need to be run in a shell):
The output of 'uname -a'
The output of 'sudo ifconfig -a'
The output of 'sudo lspci'
The output of 'sudo lsmod'
The entire contents of the file '/etc/network/interfaces'

Would be helpful to know what you have tried in response to the Google potential solutions?

1135987 2010-09-10 16:27:00 Edit the file '/etc/network/interfaces' to add the following two lines:
auto eth0
iface eth0 inet dhcpOnce you've done that, reboot the system.

Did that fix your issue, or are you still having problems with it?

When you tried to renew the dhclient lease, did this temporarily fix things, or not?

Have you rebooted the router since having this problem? If none of the above helped, it's possible that the router's DHCP server has simply crashed.

1135988 2010-09-11 03:37:00 Erayd, I really appreciate your help. I feel that with your assistance, I will resolve this problem. Here are the answers to your questions:

Did that fix your issue, or are you still having problems with it?:
No, I still have no internet connection. In fact, after adding the lines to /etc/network/interfaces, the icon for network connectivity disappeared from my panel. Strange, no?

When you tried to renew the dhclient lease, did this temporarily fix things, or not?
No it did not.

Have you rebooted the router since having this problem?
I have no router.

I have no router.

What do you have then?

1135991 2010-09-11 06:14:00 Agent_24, I have an Aaris modem from Comcast.

It should probably still have a DHCP server though. Have you tried rebooting it?
