    Wired Connection problem

    i'm a beginner to linux but will explain the problem i'm having

    having upgrade from 10.04 to 10.10 i am unable to connect to my network. (all instances below is wired)

    i have a cable connection which is shared via a router. when i login to ubuntu it tried to search for the network but then gives up saying network is disconnected.

    if i connected directly from my pc to my modem i am able to surf on the net. i've tried rebooting my router & modem and updating the linux drivers for my network card (intel 82566dc)but to still no avail i am not able to connect to the router.

    can anyone help?

    p.

    Re: Wired Connection problem

    You have right clicked on applet and enabled your wireless? When you left click on
    applet does it give you choices of routers it finds? Right click edit connections to wireless
    highlight to edit and make sure connect automatically. Is anything at all in:below
    Code:
    gedit /etc/resolv.conf
    What about
    Code:
    ifconfig
    does it show a functioning envirement (above)
    Code:
    gksudo gedit /var/lib/NetworkManager/NetworkManager.state
    they all say true (above)

    Run this and copy and paste results, Highlight whole thing and hit # sign in upper corner
    of Message box and will put in nice scroll box. This just tells all about your system so other users
    can see if they have same card or cards and maybe can help. A little much but gives all anyone would want.
    Code:
    sudo lspci -v | less

    Re: Wired Connection problem

    I've got this working, but think this maybe some sort of bug.

    I turned unticked 'Connect Automatically' in network manager and rebooted when I was back on desktop I clicked on Auto Eth0 in the network dropdown list and it connected.

    Mark as Solved please.
    As long as your running that is what counts. Users who know a lot about Network connections are far and few between and I am not one of them. Just know how to look
    at the obvious. So many cards and drivers out there. Glad you are up and running.
