Ubuntu Networking :: 9.04 - Internet - Wired Network - Device Not Managed
Sep 21, 2010
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.
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 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.
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 ?
Currently my setup is a road runner cable modem connected to a desktop via a ethernet cable. The networkmanager lists "Broadcom BCM440-BO 100BaseTX" device not managed. I've turned off the power to both the cable modem and the computer. I then turned on the power to the cable modem and then the computer. If I try the firefox browser, it can not connect to the internet.
Background infoMy laptop (MySN MG6.c) is dual-booted with Windows 7 and Ubuntu 9.10, and connected to the internet through a router (Digitus DN-11004-O), which is set-up to use DHCP. The internet connection works fine under Windows, and my previous laptop, which also ran Ubuntu 9.10, had no problems connecting to the internet through that router.The network adapter is an Atheros AR8131 PCI-E (also detected as Attansic under Ubuntu)stem infoResults from running various diagnostics (I have removed the output that relate to the wireless connection, as I don't use it):
Code: $ uname -a Linux valyria 2.6.31-14-generic-pae #48-Ubuntu SMP Fri Oct 16 15:22:42 UTC 2009 i686
I just installed Ubuntu server edition on to an old Dell desktop. The only problem is that I can't get the Internet to work. I have tried the following and I guess it doesn't work:
Each of those commands don't give me any error and it would seem like everything works fine, until I try to ping google or any website and I get an error that tells me that no host was found. I am using version 10.04 of Ubuntu server.
Okay, a couple of weeks ago I was running 10.04, got an auto update that needed a firefox restart, so rather than restart, I just shutdown the computer for the weekend. When I booted the computer on Monday it would find sites (www.google.com, start.ubuntu.com) but it wouldn't download the necessary items to load the page. Now I have a windows laptop sitting next to the ubuntu box and it was online with no issues, so I know it wasn't the connection itself. So I decided that the update messed up the system so I downloaded 10.10 and installed that and ran that all last week.
On Friday I got a system update that required a firefox restart, so I ran firefox for the day and decided that since it was friday, I would just shutdown the computer and reboot on Monday.Well now Monday is here and now I again have sloooowww internet, to the point that URL.. times out and won't come up. I have tried doing a traceroute on both machines and the windows box gets all the way to www.google.com, but the ubuntu box gets about halfway there and then gets no response. I am at a loss, I don't want to reinstall every week. I did try to reboot and run the previous version of 10.10 that shows in the boot menu, but that does the same thing. One thing I did notice is that the broadcast ip is different than the machine IP, don't know enough to know if this is a problem.
A few days ago my wireless windows vista computer internet was running slow so i reset the modem. Then I went on the internet on my ubuntu machine machine and went to www.google.com and couldn't connect to the server so i tried linuxquestions and i couldn't connect but i could ping sites. My wired and wireless windows computers worked fine. So I called Comcast (my ISP) and said it was a router issue. So I looked online and it said to disable IPv6 on firefox so I did but that still didn't work.
My friend has 2 pcs, one connected to the internet and the other one used to connect (when he had windows installed) to the internet through the first one using internet sharing, now i installed ubuntu on both and the network between them has been created but it wont connect, the internet icons just animates for like a minute then says "wired internet disconnected" in other words it failed to connect.
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
After i install it i lost my internet connection . i got a message " Wired Network " " you work offline ". i use cable ADSL ,.... my Pc information HP Pavilion 6700 running with both Window 7 & Ubuntu 10.10 note... my network connection work correctly on W7.
I have a wireless network (192.168.1.0) that's bridged to the Internet and a wired one (192.168.0.0) that's only local. When I am connected to both networks, Natty wants to route my Internet traffic through the wired, local-only one.
Can I make it automatically "just work", so that the right network is chosen for Internet traffic? Otherwise, what's the workaround?
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.
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 installed a fresh Ubuntu 10.04 system. After first boot no wired network was found and no access to internet. However, in network connections there is eth0 present. All settings are as should be - IPv4 is in automatic mode and IPv6 - Ignore. I tested internet from another machine with Windows on it and internet connections is ok. I checked etc/network/interfaces and there is as follows: auto lo iface lo inet loopback
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?
my problem is that the wired internet is working on and off, or not even that, only when it wants too. I have googled and googled, which by the way is not loading at all at the moment, and have not found anything. And i really don't know what's wrong. Some more details: 1) Finished installing suse 11.2 with gnome, yesterday. Internet, and google worked fine right off the bat. I have a laptop and so i suspended it to see if everything was working. 2) Bring back the laptop, no internet. I reboot, internet works (google included). 3) I leave the laptop alone, it goes to sleep mode (or what comes after screensaver).
I bring it back, no internet, i reboot, no internet. So i go to windows. 4) Came back to suse, now, and i have internet and google does not load! This is all with wired internet, i haven't had a chance to try the wireless (there isn't a signal for me to try). However, i am positive it won't work with the luck i've been having. Also, a few days ago i had suse with kde and the internet worked continously. I know it can't be related to the GUI, but it's peculiar.
I'm new to OpenSuSE and have just booted up an Acer Aspire 4736z laptop with the 11.2 livecd. All of the specs (gathered from lspci -n) are available here: Debian HCL - Acer / Aspire 4736Z. Wired internet does not work. I have tried `modprobe atl1e` then `service network restart`to no effect. NetworkManager says nothing is plugged in (perhaps a hotplugging issue?). eth0 is listed in ifconfig.
I keep losing internet connectivity from within OpenSuse. I've had ubuntu/kubuntu beforeand never had a problem. I installed opensuse and now after a few minutes of browsing I'll lose my internet connection.I also dual boot into winXP without any problems.I noticed that when the connection is lost I can't even reach my router - which is where I'm getting the wired connection from.So it's not just the outside internet but the local network too. It only happens within opensuse.
I just installed debian, durning the installation i opted not to connect to the internet since the large network cable was in the closet and i did not feel like standing up. Now i have finished installing and plugged the network cable in, expecting it to "just work", this is not the case. What needs to happen before the wired network connection starts working? also, the lspci output, appearantly it won't find any network adapter. I suspect this is the fault of my lazyness.
I have just done a new install of the latest opensuse 32bit and for some reason I cannot connect to the internet, when I click on mange connections the vpn tag is highlighted and all the other tabs are grayed out and I cannot select them. So I can't setup a internet connection wired or wireless. I was just using Kubuntu and did not have this problem. My card is broadcom.
I just added a 2 port network card to a system that is running Fedora 11, but it is INACTIVE. I open the Network Device Control to activate it but there is no network ports in Network Device Control. It is empty.It looks like the system recognize the card and loaded correct driver.
I'm on opensuse 11.4 (11.3 won't work with my monitor).
My computer gets internet through wireless and I want to share that internet through its ethernet port. So far I've tried using Knetworkmanager to create a network bridge between my wireless and wired connections. I created a new wired connection and shared it using the ip address settings. I was able to get both connections active, but the device hooked up via ethernet had no internet connectivity.
I also tried this command: echo 1 > /proc/sys/net/ipv4/ip_forward
but another test resulted in the same fashion (no internet on wired). I believe anything I add to /proc should have an immediate effect, correct?
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".
I have the problem with my notebook, that, after I used it at work, the network-manager always tries to autoconnect after boot. He has no cable network and so I get the message "not connected" after a while.how to tell the network-manager, not to autoconnect each time?
I installed Linux 6, configured the network during the install with a static IP and when I do an ifconfig command it doesn't show an IP Address. Can't get out to the Internet because I don't think I have an IP/Address. I restarted network, went into preferences-network connections and everything looks fine, ran system-config-network and everything looks fine. When I do an ipup ifcfg-eth0 and get the message "Connection activation failed: Device not managed by NetworkManager". Is there an option I failed to load at install or I need to install now?
I just installed Ubuntu 11.04 desktop on my desktop in dual boot with Windows 7.
Heres my problem, I am unable to connect to the Internet even though my wired Ethernet connection says it is connected normally. The wierd thing about this is that I also have a wireless card in my desktop and when I connect through that I am able to connect to the Internet. I am connecting to a router that is functioning as a repeater to my main router/cable modem. I have tried to solve this myself but am having no luck. Ironically, earlier today suddenly my ethernet connection worked for a few minutes without me modifying anything.
The output of some terminal commands are below.
