    I just installed a copy of Ubuntu (6.10 "Edgy Eft") on one of my computers. Everything went smoothly; I was connected to the internet, and could view websites. When I shut down the computer and turned it back on later, my internet connection was suddenly lost. This computer is connected via LAN. How could I fix this problem?

    Any help would be greatly appreciated.

    Thanks in advance.

    Nope, it says my eth0 is already configured >_>

    ifconfig:

    Code:
    eth0       Link encap:Ethernet HWaddr 00:07:E9:AA:5F:92
               UP BROADCAST MULTICAST  MTU:1500  Metric:1

    eth0 is not configured like it should be.Try reading one of the perfect setup howtos about configuring the network for static IPs.Maybe Your system is set on recieving network settings from DHCP and You don't have one on Your network.

    Does
    Code:
    ifconfig eth0 192.168.0.100 up
    work? (Replace the IP address if necessary.)
    Any error messages when you run this command? What's the output of
    Code:
    ifconfig
    afterwards?
