I think that's all that would be needed to help diagnose the issue. I'm kinda new to linux, and this is primarily a music machine.

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 ?

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?

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'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:
lshw:
Code:
hbarta@willow:~$ sudo lshw -c network
*-network
description: Ethernet interface
product: 82540EP Gigabit Ethernet Controller (Mobile)
[Code]....
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?

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.

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".

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.

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?

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 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.

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 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

I'm running Linux 11.04 and my wireless network was working just fine until today. I cannot connect to WiFi - it acts as if the device wasn't there. The hardware switch led isn't working. No matter how much clicking on it, it won't work.
iwconfig:

I have freshly installed ubuntu 9.10 and moreover i am completely a newbie to Linux. The problem now i am facing is, i am not able to configure my wireless router. I tried finding drivers for it in System->administration->hardware drivers. But it showed me none. Then i checked out one of the threads in this forum and came across the 'lspci -nn' cmd. This gave me the info abt my wireless network controller and it was : 'Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01)'.

I've tried to install Linux systems have been failures. Trying to make this work, trying to get on the right wagon, and it's frustrating as all get-out.
Installed netbook remix onto a HP Mini 1000 (1116NR?) and everything seems to be working alright, except no wireless networking. I tried a couple of things and now it shows "device not ready" instead of "disabled", so I figure I'm getting somewhere.
The device is:
Broadcom Corporation BCM4312 802.11b/g (rev 01)
I want in. This is my 3rd try over the years of running Linux and I always hit snags like this that I can't fix because I've never gotten to play with it enough to learn what I'm doing and generally don't have a 2nd computer like I do right now.

It's been ages since I've been on here I've been messing around with BackTrack. I've come back to Ubuntu but seem to be having some problems getting my wireless network thingy working. Here are the specs of my system. Any advice on fixing this would be very very apprciated.
02:06.0 CardBus bridge: ENE Technology Inc CB1410 Cardbus Controller (rev 01)
02:08.0 Ethernet controller: Intel Corporation 82562ET/EZ/GT/GZ - PRO/100 VE (LOM) Ethernet Controller Mobile (rev 01)
10:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)
On another note I'm trying to run debain I've got no startx on there or anything like that it's feeling very basic atm. I want to keep startx outta there but I can't connect to the Internet and run apt-get install to grab handy things.
I'm hoping whatever I am gonna do to solve this on Ubuntu will let me connect up to my wireless network with the internal network thingy. However if it doesn't I'm guessin I can just connect up physically to the router. Any tips on doing this from the command line?

I just recently installed ubuntu, my first experience with linux. I don't know if it isn't recognizing my wireless card or if it is another issue, but I am unable to view any wireless networks/connect to any. When I click on the network icon it says "wireless" with Device Not Ready underneath.

I've been using Ubuntu for a while, but I have never tried to set up a wireless device with it. I have no idea where to even begin. I've done a search of the forums but wasn't able to glean much from it.

I am running UNR on an Asus T91MT and everything was working great until an update yesterday, my OS froze while updating and I had to do a hard reboot. Since, I have not been able to get wireless, and lshw does not even recognize the presence of a wireless device on the system.

I recently bought a new nettop and installed Ubuntu 10.10 Desktop. Unfortunately the on-board wlan is kind of crap so I bought a USB Wireless stick and since that stick has a pretty recent chipset ndis was needed to get the USB stick to work as wlan1.
The issue is I want to disable the on-board wlan (wlan0). The BIOS does not offer that option so it needs to be done in the OS I guess. My question is what is the best way of doing so? I've read something about blacklisting or editing 10-wlan.rules but I am unsure what the best place is and what to put there.
This the output of ifconfig:

11.04 64 bit I just picked up a new high-gain usb wireless adapter that I would like to use for a while in place of the built in wireless adapter in my desktop. It is detected and works just fine. My question is this: Is there any way I can disable just the built in adapter and leave the new one active (or visa versa?) I don't want to remove the built-in one as there will be occasions that I will want to use both.

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?

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?

It seems the only thing this applet is useful for is connecting to a wireless network.....and only with dhcp !!

I'm new to ubuntu and using 9.10. I have installed a dlink wua 2340 wireless adaptor and it is working properly. But after waking up computer by standby mode, wireless connection breaks and the wireless device is not mounted. Therefore I always have to shut down the computer and restart again to establish wireless connection.
