sorry[/B] if i sound a bit dumb , but after upgrading from ubuntu 8.10 to ubuntu 9 my cable network did not work , whenever i log in into ubuntu , it tells me connection established but no internet working , i also lost the wireless internet , and the driver is not identified by the machine , and also the 3d desktop effect , but i am keen now to fix the cable network , so i manage to find out fixes for the other issues using the ubuntu instead of switching between it and vista each 5 minutes ,
i am using Acer Extensa , Dual boot with Vista
these are the info i managed to get , i am a bit dumb with Ubuntu

Open Synaptic and search for Broadcom.
See if there's a driver.

You have a driver istalled for your nic. What is the output of:


ifconfig

If you say your are connected, I suspect it is a dns issue. Two things you can try to troubleshoot the problem. Open a terminal and type:


ping 74.125.53.99

if you get a response type:


ping www.google.com

If you don't get a response when you ping by name, you have a dns issue.

Try ifconfig instead of ipconfig (the Windows version). Second, open the pulldown and check for eth0 instead of lo (loopback device). Then, on to cariboo907's suggestions.
