    12.04 network-manager surface
    While attempting a wifi fix, I was prompted to run the following commands: sudo mv /etc/init/network-manager.conf /etc/init/network-manager.conf-disabled sudo mv /etc/xdg/autostart/nm-applet.desktop /etc/xdg/autostart/nm-applet.desktop.disabledHow can I reverse/undo those commands?I ask because I could not get the wifi-fix to work, but am now unable to revert to an old workaround. I suspect this is because of changes made by those two commands. And so until I get this resolved, I cannot connect

    I installed ubuntu 12.04 on my Eee PC 1000H and I tried to connect my Samsung S8000 to USB. First connection was a success: PC recognize my phone and I was able to connect to internet with my phone. Later, I turn on my notebook and connect my phone, but in Network Manager I cannot find my connection. So I choose modify connections from NM and I delete the connection, then I connect again my phone with USB cable and again start the automatic procedure to set the connection. Again I connect to int

    11.04 wireless network-manager atheros
    For the most part my Wireless network works perfectly fine. But about once a day, at random times I get disconnected and the key ring authentication for my wireless pops up. All of the correct information is entered in key ring but when I hit connect, it is unsuccessful at reconnecting to network and the authentication window pops up again. The network is in working order and this is the only computer effected. This is fixed by restarting my computer, but it is a production machine so having

    network-manager ifconfig
    My problem is that at univ. each desktop computer is given a ‘fake’/’cloned’ MAC address which is recognised by our network and let us in without further authentication/VPN and the likes (don’t ask why – stoped asking that myself. unfortunately i am the only one with linux here, the windows have cisco nac agent).Therefore when creating a wired connection over ethernet (using NetworkManager – this is for Ubuntu 12.04 and 13.04), we are supposed to fill the box ‘cloned MAC address’ with the said f

    internet network-manager mobile-broadband
    I have been using Huawei USB modem to connect to internet in Ubuntu 12.04 and earlier without any problem but it continuously disconnects in Ubuntu 13.04. Sometimes the network is shown connected but without any internet connection. I have to restart my PC or remove the mobile broadband connection in connection manager and make a new one to be able to connect to the network. Moreover, sometimes after this problem the network manager applet just crashes. Network manager also gives some odd names

    12.04 networking network-manager vpn network-bridge
    I’ve set up a network bridge which I’m using to connect KVM virtual machines on my desktop to my home network; I’ ve don this the manual way by creating the bridge in /etc/network/interfaces (the way it’s done by the book for best networking performance, and we’re using on our company virtualisation servers). This, however, means that NetworkManager isn’t managing the eth0 interface any more, and is refusing to set up VPN connections.That wouldn’t have bothered me so much if I could find an app

    wireless 12.10 network-manager
    I’m using Ubuntu 12.10 with Gnome 3.6 on a brand-new Samsung NP900X4C.The installer detected the wireless adapter, took in the SSID and WPA passphrase, wrote these into /etc/network/interfaces and connected perfectly.Once installation was finished I wanted to switch to using NetworkManager to manage the wireless adapter, since this is much more convenient than fiddling with /etc/network/interfaces every time I find a new hotspot.Therefore I edited /etc/NetworkManager/NetworkManager.conf to set:[

    vpn network-manager
    I spend my days hopping between VPN connections in Ubuntu 10.10 and this is becoming severely annoying. What happens is that every once in a while – typically several times a day – when I click on the networking icon in the top bar, the nm-applet’s VPN Connections flyout menu is gone. (Said menu item is still there, it just doesn’t have a submenu or do anything when clicked.) Every time I killall nm-applet and start it again, which usually brings the menu back. Has anybody here experienced this

    I feel my panel is pretty redundant. I use gnome-do as a launcher and I use exposé to check what windows I have open. The only thing in there that I need a panel for is Network Manager/Notifications. Is there a way of managing notifications without having any visible “bar”?

    I am having with the NetworkManger Applet 0.8.1 on Ubuntu 10.10 AMD64. It (or NetworkManager or my wireless driver) seem to crash occasionally, which means I lose all network connectivity. How can I debug NetworkManager and the applet on startup and login? I want to know what is causing the problem so that I can fix it or file a bug report.Edit: This page provides some good details about debugging the NetworkManager daemon, but I’m still having trouble with the applet (e.g. the applet crashes, I

    network-manager
    I am connected to a router by wifi or lan. But every few moments (sometimes seconds, sometimes half an hour) my connection to the internet breaks down. So in one moment I can surf with my firefox and have ping times of 20 ms (wifi) to the google server. And in the next moment I can’t open any pages in any browser and the ping shows no new messages first and then “Destination Host Unreachable”. This is especially odd as another computer or my smart phone stays connected at the same time to the sa

    I’m running Ubuntu 12.04 LTS on my Asus U56E. This problem appeared after an update about 2 weeks ago. After a random amount of time, sometimes 5 minutes and sometimes a few hours, my wireless connection drops. The network-manager will show networks, but I’m not able to connect to them anymore. After running sudo service network-manager restart, I see no networks in the network-manager, and it tells me: “device not ready.”If I put my computer to sleep and resume, it brings back my desktop, but e

I have this script in /etc/NetworkManager/dispatcher.d/ directory. When I run the script manually saying “sudo mount-on-vpn asdf vpn-up” it runs fine. But whenever NetworkManager wants to run it it fails and the syslog says “script exited with error -1”.

    wireless 12.10 network-manager security wpa2
    I am on Ubuntu 12.10 and for some reason my wireless connection is using WEP when it is set to use WPA/WPA2 Personal. Also I should mention that I used to be on 12.04 and was experiencing the wireless connection automatically creating a different wireless connection profile that used WEP. It showed up as Siddhion1 and I would always have to deleted it from my Network Connections list. So it seems that this problem has migrated to 12.10 maybe because I upgraded and did not do a fresh install? An
