Networking :: Network "not Managed" After Hibernation
Jan 18, 2011
I'm running Linux Mint 9 KDE on a HP 6735s laptop. Wired internet connection worked out of the box; for wireless I had to install some propietary wireless drivers (Broadcom) before I could connect to my home wifi.Last night the laptop stayed on while running on batteries, and it eventually shut itself down when the batteries ran out. Today I have no connectivity whatsoever; not wired, not wireless. The network tray icon says "not managed".
I have installed qemu/kvm and created a Bridged network connection which works just fine(Windows 7 VM won't work in NAT mode.)
But when I try to use NetworkManager it says that I have no network connection because the network isn't managed, (I set the settings in ifcfg-br0 and ifcfg-eth0 to be managed)
The real problem is that now I can't use my VPN connections (I have many) in NetworkManager.
Is there a way to have both of these pieces of functionality?
I use my T61 both wireless and in the dock, where I switch to the wired connection. After the latest round of updates, I seem to have lost the ability to switch to the wired network. When I turn the laptop on, I see it connect to the wireless network, but when I left click on the tray icon under Wired Network is says Device not managed. I have not made any changes to anything in the last couple weeks, besides some updates. How do I go about getting the wired network back in there?I tried to add eth0 back into System - Preferences - Network Connections, but whenever I try and add eth0, but it still says Device not managed.
Just purchased a Asus USB-N13, and having follwed a mixture of tutorials, including the readme on the driver disk, i have had no luck in getting this adapter to work.Upon using "sudo iwlist ra0 scan" the adapter can see multiple networks, however device manager is stating that the device is not managed. How can I get this sorted and connect to a network?
After the use of pppoeconf, the network manager does not recognise neither the wired nor the wireless connection anymore. (It nicely did it before that) I tried to replace the etc/network manager folder with that of a different machine. Still the same. What else can I do to reset Network Manager ?
I'm having trouble getting onto the internet with ubuntu 9.04. I have just moved house and have just got the internet set up here (typing this on windows laptop with wireless). My ubuntu desktop is plugged in to the network, but in the top right hand corner when I click on the network icon I get: "Wired network device not managed"
In my old house I had a static IP. Is this anything to do with it?
I'm running Squeeze and I'm looking 3 days now for a solution in some weird problem. The NetworkManager Applet shows that there isn't connection although I am connected. The icon has this small "x" and when mouseover it says "No network conncection". Moreover when left clicking it, it says
"Wired Network Device not managed"
While I was looking for the solution a came across this post by an Ubuntu developer who says:network-manager-applet displays the connectivity state of network-manager's managed interfaces not every interface. So the title "network manager says disconnected but is connected and working" is actually misleading. The interface is connected and working but not from network-manager's point of view since it is not managing the interface. Additionally, in Lucid now network-manager applet displays nothing now for non-managed interfaces so is less misleading. You can check to see whether or not an interface is managed by network-manager by using the command line too nm-tool. You'll see "State: unmanaged" for unmanaged interfaces.
Can you "split" a network interface in Ubuntu, similar to how airmon-ng lets you use your wireless card in managed and monitor mode, by making another interface out of the same hardware? I know it'd be slower, but I'd still like to do it.
I have been running SUSE 11.1 on my HP laptop for over a year. For the most part, I am thrilled with it. However, when I awaken the computer from hibernation mode, I have to go into the Network Settings applet proceed with the wizard in order to get my wireless connection working.
Another irritating aspect is that if I go to a place with a Wireless Hotspot, the computer doesn't automatically pick it up. Again, I have to go through the Network Settings applet to get it working.
I want this to work as it does on Windows XP/Vista where I can put the computer to sleep and when I awaken it, then the wireless connection is automatically there for me, etc.
I have to think I probably need to tweak a setting somewhere, so if someone can tell me where to do this, great!
I am using an internal wireless card (Atheros AR928X PCI-EXPRESS). If you need additional info, let me know.

Bind on Fedora 14 is driving me crazy.I am getting messages when I restart BIND stating it cannot find the managed-keys.bind file but it's right where it's suppose to be, and the directory is writable.
I have a problem with my internet connection this is the picture the device is Realtek RTL8187. i didn't know how can i manage this device to work so could you help me i don't have an internet connection in ubuntu right know and i really wanna move to ubntu my verison is 9.10
I'm getting rather fed up with this Network Manager applet on Ubuntu and its seemingly erratic behavior.I often use my laptop for things like dhcp server to do pxe boot on other machines for netboot installs and other stuff. Often I have to set static address on eth0 etc.I know how to set a static address for eth0 by editing /etc/network/interfaces and all that good stuff, but when I click on the Network Manager applet, it says 'Wired Network - not managed'.I may have deleted it for some reason, but why does it no longer appear, even though eth0 is working?I've also found in the past that changes to interfaces in the Network Manager, such as giving eth0 a static address, do not seem to stick?
I'm trying to get a wireless PC (PCMCIA?) card working under 10.04 desktop. It does not seem to be recognized by nm-applet and I cannot see any particular reason why. I have disabled the built in wireless (Intel 2200) in both BIOS and by blacklisting the appropriate module so there should be no interference from that. The card is a Linksys WPC300N V1. It has Power and Link/Act LEDs both of which remain dark.
Here's the information I have collected regarding the card:
I saw a comment about 'You need to have "managed=true" for NetworkManager to bring the interfaces up. in '/etc/NetworkManager/nm-system-settings.conf and did so but I see no change.
I understand that modules must be compiled to support network-manager but I would expect that to be the case with modules that ship with 10.04. I don't see any obvious indications for why this is not coming up with network-manager. Is there something I;m overlooking or something else I need to do?

It seems the only thing this applet is useful for is connecting to a wireless network.....and only with dhcp !!
Right now we are running a gigabit network with unmanagead switches. What do i gain performance wise and capability wise with moving to smart and managed and do these benefits make the cost worth it?
I have 2 wlan cards. wlan0 and wlan1. wlan0 is in AP mode(Master mode) using hostap. wlan1 is connected to another wireless network and is in Managed mode. Now I want to make a bridge between wlan0 and wlan1. I do it like that:
I'm attempting to set up a VPN server on my box using the nifty HowTo posted here: [URL]
My setup is as follows:wifi0 --> Internet; managed entirely via nm-applet (NetworkManager) Where I'm running into trouble is in the creation of a bridge interface (br0) to bridge future VPN clients to my local network.
The guide(s) say that I need to screw around in /etc/network/interfaces to setup br0 and [eth0/wifi0] accordingly. The problem is that when I specify a configuration of any sort for wifi0 (my only choice for a network uplink), it disables nm and I am unable to configure my wifi in any sort of sane way after reboot... Further info: this "server" doesn't move, and always always connects to the same wifi hotspot that is also nailed in place.
Yesterday I did an upgrade and today my box is unable to connect to the internet.
I have tried another cable, it didn't help.
Basically NetworkManager does not connect eth0 to the network, if I try to run ifup from the command line I get:
Code:
I can see in network configuration settings, that the device has been correctly detected and eth0 interface is correctly activated, yet when I try to uncheck the box manage by NetworkManager and start it manually, it tells me that the cable is disconnected... I've tried two different cables, different ports on my router - no help.
Following upgrading my 09.04 partition to 09.10 then 10.04, all was working fine until I tried hibernate out for the first time - big mistake! If I can get to a position where i can log on to the system, I find that my ethernet network connection is disabled and I cannot get it to restart. My 09.10 system still works ok. I am tempted to do a clean install of 10.04, even though I'll have to spend some time reloading the extra's and re-configuring.
I am having a problem reconnecting to the internet when I put my computer in suspend or hibernate. For some reason when I put my computer in any one of these modes it disconnects from the internet, and I have no way of getting back on the internet after that. I use to have the option of "Enable Networking" on my top panel, but it seems to have disappeared for some reason. Is there any way to stay permanately connected to the internet, even when it is in hibernate mode, or could someone tell me how to get the enable networking icon back?
My wireless connection has been giving me some problems, so I decided to try a wired connection directly to the router. However, when I try to do that, it doesn't work. When I click the network manager icon, it says that the wired device is not managed.
ifconfig gives this:
Link encap:Ethernet HWaddr 00:13:d3:dd:12:79 inet addr:192.168.1.100 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::213:d3ff:fedd:1279/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
[Code]...
I ran sudo dhclient to try release and renew my IP, in case that was the problem. It released and renewed successfully, but still didn't connect to the Internet.
I am trying out a Debian system on my at home desktop. The way that the desktop connects to the internet is via a wireless card. The installation went fine to my knowledge, I used a CD and the installation even used the wireless internet (albeit slowly) to download the needed packages to complete installation. Now when I try to connect to the wireless network Network Manager says that Wireless Networks are "not managed." I feel like I'm probably missing something either really simple and silly or something really big requiring a re-installation. Either way I can't even find an instance of this happening to someone else's system.
Finally got skype working on my Fedora 11 x64 version. Well, of course, the first thing is to download the 32 bit "skype-2.0.0.72-fc5.i586.rpm" from Skype official website..At first, I found a guide on [URL].. and followed the instruction.Installed skype using
Then searched through and found out another "Howto" for F10.. http://forums.fedoraforum.org/archiv.../t-217122.html I tried to yum, but none of the following packages are found.
There are also some thread talking about this problem but I forgot to bookmark them. It seems that skype needs 32 bit lisa.. So I then installed the lisa-lib-1.0.20-1.fc(i586). Meanwhile, I configured sound in, out and ring to hw... Also disabled "Allow skype to adjust .. mixer level" . When I run skype from xtern, it still reports erors related to lisa.. But it works now...
On standard Linux setups you have two general paste buffers, the main copy(^C)/paste(^V) one and the select-text/middle-click one. For both of these buffers:
At what level in the environment are these buffers stored/managed; the kernel, the X server, KDE/Gnome, or some other service somewhere? Can they be programmatically accessed somehow using some standard library?
did anyone manage to install Ubuntu 1 in Kubuntu? I tried a few ways but still can't make it run. I managed to install it on Win XP and an Android phone, really weird that there's no explicit support for Kubuntu
when I first installed it on my IBM thinkpad, the eth0 was working correctly. I had someone try to install the network card for me, and something was changed to where now the wired connection is displaying "device not managed".
Anyone managed to install Ubuntu 10.04 on a box with Intel Core i7 920@2.67Ghz processor. I downloaded ubuntu-10.04-desktop-amd64.iso & ubuntu-10.04-alternate-amd64.iso ran md5sum's, burnt them to DVDs & CDs but couldn't manage to install the 64-bit version. For some reason the installations abort. I've got Ubuntu 9.10 32-bit version running on the box right now.
