    Need help with wired connection

    Hello everyone. I just started dual-booting with W7 and Ubuntu 11.10 last night and my internet worked great, but today, it keeps disconnecting when I try to connect. Here's what I saw when I typed "ifconfig" in the terminal:

    eth0
    Link encap:Ethernet HWaddr bc:5f:f4:1a:b3:8d
    inet6 addr: fe80::be5f:f4ff:fe1a:b38d/64 Scope:Link
    UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
    RX packets:12 errors:0 dropped:14 overruns:0 frame:12
    TX packets:285 errors:0 dropped:98 overruns:0 carrier:0
    collisions:0 txqueuelen:1000
    RX bytes:4482 (4.4 KB) TX bytes:60739 (60.7 KB)
    Interrupt:45 Base address:0xa000

    lo
    Link encap:Local Loopback
    inlet addr: ::1/128 Scope:Host
    UP LOOPBACK RUNNING MTU:16436 Metric:1
    RX packets:144 errors:0 dropped:0 overruns:0 frame:0
    TX packets:144 errors:0 dropped:0 overruns:0 carrier:0
    collisions:0 txqueuelen:0
    RX bytes:11488 (11.4 KB) TX bytes:11488 (11.488 KB)

    Thanks in advance,
    Andrew

    Re: Need help with wired connection

    Hi Andrew,

    Welcome to Ubuntu. The ifconfig output you gave shows that you have not been assigned an IPv4 IP address for eth0 (your wired connection), so you cannot connect to a network.

    The easiest way to set up a network connection is using the Network Connections GUI, which is available from either typing network into the dash search, or typing nm-connection-editor into a terminal.

    Add a new wired connection and fill in the appropriate details. Most likely you will want a DHCP address (from the "IPv4 Settings" tab) if you are on a home broadband connection, otherwise you will need to add specific details for a static address, but you will probably know these in that case. The best advice would be for you to play around with the settings until you find what works for you.

    Hope this helps,

    Jimmy
