Internet stops working suddenly with ubuntu 8.04.1
 

Last night I reformatted the hard drive of my Dell inspirion 6000 ( I believe its about 2 years old) and installed ubuntu on it. After the installation I plugged in my Ethernet cable and the internet did not work. I realized that the network was connected to the wrong port and changed it then the internet started working. This morning it worked long enough for me to check my email then I closed firefox, reopened it not even 5 minutes later then firefox says "page cannot be displayed". I'm a noob when it comes to ubuntu, but I'm not computer stupid to put it bluntly. I'd like some one to explanin whats going on to me, or how to fix it. When I did ifconfig I copied what it displayed to see if anyone may know what the issue is. Thanks!

Can you ping out? To another IP, not a domain name. Also, what's route say? Can you give any more details about your network config? DHCP?
