View 9 RepliesI 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.
View 2 Replies View Relatedthis isnt happening on ubuntu but I think this is more or less a kernel problem that could happen with any flavor. After a new install off of a live cd my wireless card is not picking up any signals...i was able to use wireless while using the live cd but now after it has been isntalled to the hard drive it is not working. even tried in terminal to manually look (iwlist wlan0 scan) but it isnt picking up the signal
View 2 Replies View RelatedThe device it's properly recognized and iwlist scan even list the networks, but the "activate wifi network" on the network manager on right-top of the screen it's grey and therefore cannot be activated. This seems to be the problem ( rfkill list ouput ):Quote:

When I first turn it on to the desktop, it automatically connects and disconnects automatically 5 times then sometimes it would disconnect a few times randomly out of the blue.
This ia an external single usb wireless adapter you plug in the usb port on my desktop tower.

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.
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 ?
View 1 Replies View RelatedI'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.
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:

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've just installed Ubuntu 10.04 on my samsung n150. It has the 8192 device in it. Have installed ndiswrapper, however cannot get the drivers for it. How to fix/where to get the driver from so I can get my wireless card working again.
On lspci:

I think the driver may be there, however I just can't 'enable' it. On my laptop there is a blue light saying that wifi is enabled however who knows.

Device 8172 (rev 10)my problem is that I can't connect to my wireless network with Gentoo. I've been running Slackware64-13.1 on this computer and now have Windows 7, Ubuntu and Gentoo installed. Slackware, Ubuntu as well as Windows 7 connect to the wlan without problems. I'm using the driver rtl8192se, the module is loaded r8192se_pci and is the same with Slackware and Ubuntu.
I've read many posts and found that other people experience problems with Realtek wlandevices as well. But I have no Idea how to get connected with Gentoo at my wlan. It looks like that the netbook is connected for a very short time, but when dhcpcd broadcasts for a lease the connection is already closed.
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".

View 3 Replies View RelatedI 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.

View 2 Replies View RelatedOK, after searching several dozen posts I still have no clear answer to a problem connecting to the internet with my Alfa AWUS036H Wireless USB adaptor. (Computer is an Aspire 5516 w/ AMD Athlon 64 processor)The device shows up in the network manager, (with great signal strength on many local AP's)and works well with Aircrack for security testing, which is why I got it in the 1st place. However my onboard Antheros wifi card just does not receive as well, thus I'd like to be able to use the Alfa for internet. Any thoughts here would be appreciated.
View 9 Replies View RelatedI'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

View 1 Replies View RelatedThis is wireless adapter: [URL]... USB/Detail.bok I have 2 AWUS036H Wireless USB adapter that uses the RTL8187 Chipset connected to a USB 2.0 Port. It is very slow when I try to go to websites or download anything using Ubuntu 10.04 Lucid Lynx. The max speed I can get out of it is 135 Kilobytes per second when downloading anything. But when I am on Windows I can max out 2.6 Megabytes per second. I have been trying to find a solution but have found none. When I look at the light on the wireless adapter and compare it to what it looks like on both Ubuntu and Windows. It seems that the wireless adapter light is dimmer on Ubuntu. So I was thinking it was txpower set very low. I changed it but no success on changing speed. I am using WPA2-PSK which obviously uses AES. I have also tested it while it is in WEP and when it is Open with no change in speed. Speed results Ubuntu 10.04: Speed results Windows 7: I changed the settings to Megabytes on those speed results.

Ditching Windows for the last time but this seems to be a issue wireless seems fine for a bit but then the connection slows to around 20kbps or worse. Any ideas what it could be? Using 10.04.1 it says it has a 48mb connection and i have 4 bars.

View 10 Replies View RelatedI buy a new usb network adapter (Through DX), when I try to use it in ubuntu or BackTrack4 Final it is working, and connecting networks even with WPA encryption. But after few minuts it stops working totally. It is showing that I'm connected to the AP but web sites do not respond.
Notes:
- I have another PCI Wireless adapter which works fine.
- The problematic adapter works great on windows.
- A driver CD came with it, including a linux driver which I wasn't succesfully installed.
- A BackTrack3 Disc came with it, claming by the instructions that the adapter will work with it. I didn't try it because i have backtrack 4 final.
It took me dozens of surfing the web hours, and too many restarts,
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?

View 1 Replies View RelatedI'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.

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?
