Well, I've got a wired network on my Ubuntu 11.10 fresh installation. I can download files and surf the Internet. The problem is that sometimes it takes a long time to load websites and sometimes it gives up trying. I also unsuccessfully tried to connect to an FTP server using Filezilla. The same wired network does work fine in a dual-boot installation of Windows 7.

How can I configure my network appropriately.

SOME INFO:

$ sudo lshw -class network
