Ubuntu :: Network Manager Disabled After Suspending?
May 14, 2010
What happened:- I run out of battery (laptop)- I believe Kubuntu tried to suspend to disk, but that failed, the system froze- after reboot the system tray applet just told "network manager disabled" How do I fix this ??.. I tried but after entering the second line of code it says no such file/directory exist...
service network-manager stop
- a wired network - a wireless network - a mobile broadband network as both "system connection" and "automatic connection".
I need to have a laptop that will try to connect as sson as I plug the ethernet cable in or as soon as it senses a certain SSID or as soon as there's a mobile broadband device plugged into a USB port. Non-system connections are working but I am not willing the actual user (non-admin) to read the WPA2 key or the SIM PIN. But the check box for the system connection is disabled. And running "sudo kcmshell4 --icon networkmanager kcm_networkmanagement kcm_networkmanagement_tray" doesn't result in a system connection.
I've installed ubuntu 10.04 on a hp mini 110. I've used netbook remix on this same computer and had no problems with a wireless connection. In this case, network manager shows wireless disabled. I have installed the Broadcom B43 Wireless drive from Adminstration->Hardware drivers. No help! ifconfig does not show eth1 and lspci tells me that the Broadcom BCM4312 Network controller is present.
I had installed Fedora 12. I am using 4 LAN Cards. All these cards were configured using network manager, but i am not able to acivate /deactivate these cards using acivate /deactivate buttons since they got disabled. I could activate the cards by running /etc/init.d/restart network. Anyone knows why the acivate /deactivate buttons in network manager are disabled .
I did a fresh install of OpenSuSE 11.3 KDE 64-bit on my new laptop. Worked like a charm. But I brought it with me to work without connecting it to a wi-fi and now the network manager doesn't want to start when I'm back in range of my home connection. Also, whenever I try to launch KNetworkManager, it won't load up a window and I still can't connect. This is even disabling the Ethernet port also.
I have been running FC8 on this IBM T23 with a D-Link wireless adapter. Using MadWifi this has worked fine with Network Manager disabled. But now I have nuked that installation and replaced it with FC10. Network Manager is nice, and I would like to use it. And it kind-of works. Network Manager recognizes my router and all my neighbor's routers, but I can't connect.
I've just switched from xub to lub, and I must say it's a lot lot faster. There's just one really annoying problem (I have no idea if this is in any way related to LXDE or if it's just due to 10.04): Network Manager only starts about a minute after the rest of the desktop. So my system boots up, I log in, see the applet, but it is greyed out (it tells me "Network Manager is disabled" or something similar). After a minute (approx), it suddenly comes to life and connects me. Now, I think this only happens when I have:
A) set the wireless connection to "all users" B) given an empty password for the keyring
But when I cancel either of the two above, it doesn't stop it from happening. I've tried updating etc.. to no avail. I've also tried wicd, but for some reason installing wicd from synaptic doesn't remove Network Manager? Anyway, has anyone seen behaviour like this? Any suggestions for first steps to take to see where it's blocking?
I had trouble connecting to a wireless network with openSUSE, so I tried the YAST network manager to see if that fixed it. Not only did it not fix it, but now I cannot connect to any network, wired or wireless. I tried to open the default network manager and it said "Network management disabled". How do I re-enable it?I also have set YAST settings back to their originals with no luck.
After I upgraded to ubuntu 10.04 my internet connection was working fine( both wired and wireless) and now all of a sudden knetworkmanager has disabled itself so I cannot get online at all. When I leave the mouse to hover over the icon it says unmanaged. Does anyone know what could have caused this and if theres a fix?
I tried connect to internet through iPhone (bluetooth tether), so I followed one tutorial... It said I have to change "networkmanager" to "ifup" in yast>network settings, and make some other changes... I did it, but I couldn't connect via iphone... OK... I put back all changes, also changed ifpu to networkmanager.
After reboot, Knetowrkmanager gives me "network management disabled" on startup, instead of list of my networks.
Of course, I google for solution, but without any luck. And then, I don't know why, I killed Knetworkmanager, start it again, and.. it worked!
But now, I have to kill it, and start again always, when I reboot my laptop...(HP Compaq 6720s, BCM4312, KDE 4.3.4)
I have an Asus EeePc 1001PX and on resume I have "Network Management disabled", neither wired nor wireless interface can be configured, the NM icon is greyed out. running ifconfig shows eth0 and wlan0 have disappeared completely.
I found 2 options: 1. https://bugs.launchpad.net/ubuntu/+bug/555571 2. Network management disabled after start on 11.2 - openSUSE Forums
but I don't have the /var/lib/NetworkManager folder at all
I have been trying to lighten the load that Ubuntu uses on my RAM and processor, and decided to try LXDE, as it is the lightest-weight DE that I have tried and liked. I noticed I didn't have any wireless connectivty under LXDE, so I checked the LXDE site for the solution, and it said to download and install LXNM, which supports wireless connections. Unfortunately, installing LXNM (apt-get install lxnm) also uninstalled nework-manager, and network-manager-gnome, on top of lxnm not working properly, and stranding me without any way of reinstalling the OS, and without an internet connection (I can't connect with a wired connection, either). Is there anything I can do, aside from reinstalling?
I was away from Ubuntu for a long time - since the breezy badger days. Anyway I'm trying to get back, I tried installing 9.4, it failed miserably; both standard and alternative. 10.4 installed fine, but I'm having trouble with wirless. Long story short network is disabled. No wireless networks show up. B43 driver is installed and the pci wireless is communicating with Kernel. I would copy paste, but I have no access to internet on that computer. Also 'sudo apt=get' is not beneficial when you have no internet. I'm happy to transfer from packages.ubuntu though. Left clicking and disabling /reenabling has left me with device not ready, and a driver warning to get B43 driver. I had that already but I guess I'm going backwards now.
I have installed Ubuntu Lynx 64 bit on my dell latitude e6410 with nvidia graphics. I have it running smooth thanks to the posts in this forums. today I was downloading a file and I ran out of battery (my laptop shutdown) I plug it to the charger, and know My network connection is disabled. How can i re enable my network connection?
i resently bought HCL ME with windows, i formatted and installed Ubuntu netbook version. i am getting wifi is not connection it looks disabled in network place. my network controller is Realtek semiconductor co., ltd rtl8191sevb rev 10, i am unable to get this driver to install can anyone help me ?
I am working on ubuntu 10.10 in a VM. I went ahead and did updated the system when prompted. That has disabled my wired network connection. I am not sure what is the reason. If it is a device driver or any network service. I guess device driver is not an issue as I can detect my network card from ubuntu. Does any one know the solution?
1. If you are on a laptop check that the network function key is turned on. Mine is on F12 and has a bluish light for ON and reddish light for OFF.
2. Go to System > Administration > Users and Groups > Advanced Settings > User Privileges Check you have relevant permissions for Connecting to Wireless Networks and the Internet. (Also turned my audio on here after much trial)
I discovered these after spending hours following up suggestions on these forums. They might not solve everyone's problems but they will hopefully save some of you from fruitless searching
When I ran updates and installed 9.10, this message appeared, "Network service discovery disabled. Your current network has a .local domain, which is not recommended and incompatible with the Avahi network service discovery. The service has been disabled." The computer will not respond to anything, completely frozen--I am not able to open any programs and the CPU itself seems to be running loudly.
I installed the b43 drivers to enable the monitor mode for using kismet. but after installing, it shows "Device not Ready".
The dmesg | grep b43 output shows: [ 86.449430] b43 ssb0:0: firmware: requesting b43/ucode15.fw [ 146.449335] b43 ssb0:0: firmware: requesting b43-open/ucode15.fw [ 206.448146] b43-phy0 ERROR: Firmware file "b43/ucode15.fw" not found [ 206.448153] b43-phy0 ERROR: Firmware file "b43-open/ucode15.fw" not found [ 206.448158] b43-phy0 ERROR: You must go to [URL] and download the correct firmware for this driver version.

I just installed ubuntu on my d620.The wireless card seems to exist and looks fine but I don't know how to turn it on.It says the network is disabled everywhere I look but I can't find the option to turn it on.I know this is probably simple. Below is the output from various commands.I included my service tag which you can use on the dell site to find specifics about my hardware.I can't do ifconfig wlan0 up which is the only solution I've found online so far.
I have a weird problem that I can't find the answer for in the forums or docs. I can see the wireless network in Network Manager, but it is grayed-out and inaccessible. Other wireless networks are white and I can click on them and connect to them (or could if I knew the password).
My work computer, an IBM ThinkPad T43 running Win 7, connects. My personal computer, a Dell Latitude C640 running Ubuntu 10.04, sees the network as grayed-out and therefore I have no option to connect to it.
I have tried the following:Checked for hardware drivers - the system says "No proprietary drivers are in use on this system" Verified that the network security settings are the same on both my work and personal computers: WPA2-Personal Why can I see the network but it is disabled/grayed-out?
I accidentally removed the dhclient3 file. I had ran chkrootkit and it said it was a possible suspicious file. Once I rebooted, the network was disabled. I am running off the Ubuntu cd by choosing trial. How can I get dhclient3 back onto my installed Ubuntu?
Just bought new laptop i7 with broadcom wireless, intalled opensuse 11.3 x64. I had major trouble to make it work... Even compiled kernel 2.6.37-rc6, but didnt go.Then I took drivers and firmware from git repositories, compiled, did what it was necessary and I made it work.This morning, (since system was new), I just did zypper upgrade (nothing new installed from default installation, I just added packman to repos).And, now wireless is not working. In network manager, option "enable wireless" is disabled.I went to YaST, put network on ifup, it did scan networks, but cant make it work either. Turned it back to network manager, but same thing.Module brcm80211 is loaded, but I cannot make wireless work.
