Debian :: NetworkManager Applet Shows No Network While Connected - Wired Network Device Not Managed
Oct 30, 2010
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.

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 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 am using FC14

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 this wireless card to work. I installed the broadcom-wl driver on Fedora 12.
Code:
[xxx@localhost ~]$ uname -r
2.6.31.6-145.fc12.x86_64
[xxx@localhost ~]$ lsmod | grep wl
wl 1278432 0
lib80211 6436 2 lib80211_crypt_tkip,wl
The card is recognized by System--admin--network as the correct card (BCM43XG) and assigned eth1. However, NetworkManager shows no wireless network. I have a great signal on the same machine if I boot into a Windows partition.

Just installed OpenSUSE 11.2 and I have to say it feels great.Only gripe I currently have is the NetworkManager that is starting up very slowly. When I have logged into KDE KNetworkManager applet says that NetworkManager is not running and hence I have no network connection. This is fixed if I start NetworkManager (as root) or just wait a couple of minutes. I have one ethernet interface only, no wireless

I have used the information available at wiki.debian.org/iwlagn to install firmware etc for my Intel Pro Wireless 4965 card.According to the network applet the connection is good, but it only seems to work when my ethernet cable is plugged in.I get no connection without the cable in, even though clicking on "edit connections" showshat ethernet is shown as "device not managed".With the cable plugged in I can get emails. Iceweasel will connect to the internet, but Epiphany will not.Without the cable I get no internet connection at all

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.

My sons computer /w 11.4 x64 installed a week ago, was working fine till he wanted to play with Blender.So he installed it and it would not run because im lazy and did not instruct him on installing NVidia drivers for his vid card. He added the repo and I had him run update instead of just software management (my bad) anyhow ran the update and there were updates with driver install, rebooted Blender works now.But the nic card sates its not connected in yast no ip in root terminal /w ifconfig info there for nic mac addy and such, tried reboots and reconfig in yast no joy. Dual boot into his windblows and the nic work perfect so not hardware issue.

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):

This may be more suited for the networking forums, but I figured Community Cafe would be well rounded enough for someone to tell me if this is even possible (with minimal configuration that is).There are a few places I travel where I only have a wired connection to the Internet (no wifi), but when this happens is there a simple way to create an adhoc network so wireless devices can route through my computer and to the network? Reason I'm asking is I'm thinking of getting an iPad or iPod Touch which have wireless connections, but in the cases where my laptop is using a wired ethernet connection and the wireless card isn't used, I'd like to create an adhoc wireless network that'll let such wireless devices work.

Would it be possible to insert another wired network card into the router-connected computer, share the internet connection and be able to transfer files between the two?

I have one major problem that is going to cause me to switch back to windows. My wireless network shows connected and works fine for a while but periodically stops working. It always says it is connected but sometimes stops working to where I have to disconnect and reconnect for it to start back up again.

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?

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 need a bash script to run ARPON for the connected network device, eth1 or eth2. (ethernet or wireless)
Arpon has an option (-o) to select the network automatically, but it only works for ethernet, hence i need this script. I've also tried running arpon for ethernet and wireless at the same time, but the arpon process running the inactive device will consume all of my CPU.
So, basically i need a script to find which device is connected, eth1 or eth2 and then to run arpon -d -i <device connected> (or something like that).
Is there an easy way to do this? code...
I've searched everywhere how to find the connected device via bash, but i couldn't find anything.

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 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.

I remember that I did configure my desktop PC for wired and wireless connections since openSUSE 11.2, 11.3 and 11.4. Currently I have openSUSE11.4 x86_64 KDE. Today I happen to notice that the icon for NetworkManager in the taskbar has been replaced with a red X. I discovered that Network Manager only shows VPN tab, whereas Wired and Wireless tabs are greyed out. The strange thing is I still have Internet connection with the CAT5 cable being plugged in. I can still configure wired and wireless connections via YAST but I cannot fix Network Manager settings.

I had a google of this but can't find anything useful. I use networkmanager to configure my wireless card. Currently this only works when I'm logged in to KDE. If I log out the system loses the network connection. Is there a way to make it persistent using NetworkManager?

since a few weeks I have a problem connecting to other hosts when I'm using another wireless network, which has a different DNS IP than I have in my network. I have to change /etc/resolv.conf to change the nameserver. Can NetworkManager control the nameserver? If yes, how?

I recently installed OpenSUSE 11.2 and everything works fine except wi-fi card, of course. The problem is that after installation the system recognized the card (is was listed in network devices in Yast) but I was unable to enable it through network-manager applet. Though the device could make scanning through terminal (found article in docs but didn't fully understand wpa_gui). Then i was stupid enough to delete the device from Yast list to try to reinstall it. So the problem is that i simply can't do this cause i see no way to re-detect. That is the goal is to at least turn back to post-install system state and try to enable wifi card again.

I am using opensuse 11.3 64 Bit Gnome. The problem is the network manager & the bluetooth icon takes unnecessarily long time to load (2-3mins) & until it loads I cannot connect to the internet.

Last night while setting up wired & wireless connection in openSuse 11.2 Gnome version via YAST's ifup, I got wireless but lost wired connection (interface eth0). Dmesg shows that eth0 became eth1. I cannot get eth0 back. Is there any way to remedy this situation, eg. get info from the Ubuntu partition in my triple-boot laptop, without having to re-install openSUSE?

I am a newbie when it comes to linux, but know a little (the little bit of dangerous stuff).I have set up a home web server for when I am testing website using PHP, mysql and other funky stuff. This is a reflection of my production server as far as I can with my limited knowledge.I am also using this box to learn more about the Linux operating system and I doing this slowly. Before I installed the GUI (Gnome) I was using a text based server, this was working fine and running absolutey fine and never disconnecting. This has been fine and working 24/7 for around a month.
At the weekend (just gone) I ran the following at terminal
# apt-get install gnome
This gave me a GUI so I could try some other things.
When the computer is idle the network card seems to drop the connection, Im trying to see after how long it does this. I have seen this work fine after an hour, but after a night, the network has been dropped. This is a hard wired connection to the router.first time I thought the PC had froze so rebooted the PC, but the second time, I plugged a mouse into it and noticed the the network icon had changed, after right clicking on it, i noticed that It had dropped the connection. After clicking the "reconnect" option it is back up and running.
