    Wireless Network Stopped Working

    Hello everyone,

    I am playing around with Ubuntu Server (no desktop environment) 12.04.3 LTS.

    I set everything up and HAD a working wirless network connection.

    I then ran

    Code:
    sudo shutdown now -r
    And when the system came back up it hung on something like "configuring network interface / connection." I have never been able to connect again.

    I am somewhat new to terminal-only stuff, but I tried messing around with "ifconfig" "iwconfig" etc.

    I tried:

    Code:
    sudo iwconfig wlan0 essid "MYIDHERE" key s:MYPASSHERE
    The terminal took it and the changes were reflected in iwconfig but I still have no internet connection.

    How can I go about troubleshooting this thing?

    I have "links" installed for web browsing and it is not connecting, nor can I "ping" anything.

    I am wanting to learn how to work in the terminal and do not have Gnome or KDE installed, so please let me know how to proceed.

    I tried googling an answer but I'm not sure exactly what to follow. I have seen mention of "dhclient." What is it and how does it work? Also, I tried:

    Code:
    sudo ifconfig wlan0 down
    sudo ifconfig wlan0 up
    Just trying to reset the network adapter, similar to "ipconfig /release /renew" in Windows command line.

    Thanks in advance for the help!

    Blessings,
    Cody

    A server running on wireless? Is very odd IMO.
    I usually install a minimal UI, even on a server, it's just easier.

    now..depending on what changes you have made..you can configure your network with..
    Code:
    sudo gedit /etc/netowrk/interfaces
    make any corrections...additions ..save ...close then

    Thank you! This fixed it!

    Shouldn't this automatically run every time I start the server though? Why did networking stop, and how can I make sure it automatically initializes each boot?

    Also, I realize it is strange to have a server running on wireless. I am not using this server as a server. I'm just playing around with Ubuntu server because I want to learn it better.

    Thanks again!

    Re: Wireless Network Stopped Working

    Hi, more than likely,since you are NOT using the desktop server,
    the network starts on boot. you can see if it's running by entering..
    Code:
    sudo service networking status
    you may also want to make a change in..
    Code:
    cat /etc/NetworkManager/NetworkManager.conf
    Code:
    sudo gedit /etc/NetworkManager/NetworkManager.conf
    *Change managed=false ~ to ~ managed=true
    My server is also wireless,never a problem,but i use the desktop
    server and configure my static ip with the IPv4 settings.
    Have fun playing!
    Please mark this thread solved.
    thanks.
