Ubuntu

I can't access my internet even after I configured the network.I dont know why and I even formatted and reinstalled the OS again & again.

Asked by R.Lakshmi Narasimhan

I have installed Ubuntu 7.04 recently and tried to configure the network. I have static IP address for internet connection and in network configuration I have specified all the data like IP address,subnet mask, Gateway,DNS,etc.
After that the message from OS was the network was disconnected. I have rebooted the system and tried to connect but it was not. Even after I formatted and reinstalled the OS but the same thing happened. I don't know what to do.I am sure that my internet connection is working properly. Please suggest what I should do.

Since you censored your local IP's I suppose you know about your network configuration.
1) Can you ping your gateway?
2) Is /etc/resol.conf pointing to the right dns server?
3) Can you ping your dns server?
4) Can you ping an internet address with ip? Try 64.233.187.99
