Ubuntu Networking :: Wireless PC Card Not Managed By Nm-applet?
Jan 11, 2011
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:
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?
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 have 2 wlan cards. wlan0 and wlan1. wlan0 is in AP mode(Master mode) using hostap. wlan1 is connected to another wireless network and is in Managed mode. Now I want to make a bridge between wlan0 and wlan1. I do it like that:
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'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.
Is there a way of wireless networking without using the Gnome NetworkManager Applet? I want to connect to the Internet using a USB 3G modem and connect to wifi without knowing all of the details of every network.Network manager is pretty good but there seems to be no way of using it without starting an X session and it doesn't play nice with any other networking tool and reminds me too much of a Microsoft application.
I'm not sure if I have two seperate issues or one inter-related issue. The Network Manager applet wasn't appearing in the tray, found out it wasn't installed. Installed, still didn't appear. Tried installing WiCd, WiCd did appear but couldn't find any networks. I had installed restricted drivers previous, decided it was worth another look. Found that Broadcom STA Wireless Driver wasn't installed. Tried to install, it said it couldn't and said I should review the var/log/jockey which is....excessively long.
Is there a way I can refresh the list of available wireless networks in the network manager applet? It works correctly when I've just booted but doesn't after I resume after suspending. There's just a message like "wireless networks not available".
I can assure you that the wi-fi is not disabled using a button (my laptop doesn't have such a button), "Fn" key combination or in any other way and the network doesn't go down when I need 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 Ubuntu 10.04 Server. I can't get my Wireless Card & Wired Card to work at the same time. My interfaces file is incorrect, when I comment out 1 of the interfaces the other works. I have attached my interfaces file.
I am having issues with wifi on my Lenovo X220. What has occurred is that the network applet in the notification bar no longer shows me any wireless network options. When I click on the applet, the drop down shows me: Wired network: disconnected (greyed out), VPN connections, Enable networking (checked), Connection information (greyed out), and Edit connections. Missing is Wireless connections. This occurred "out of the blue" in the middle of using the computer (i.e. NOT just after a reboot or new driver installation, etc.)
I have noted that:
1. Wired ethernet works just fine.
2. Wireless (wifi) works when I boot into Windows 7 or into a fresh Ubuntu USB Start up disk (implying that this is a software issue, not hardware).
3. The hardware led for wifi is OFF (whereas the Bluetooth light is on.) In Windows or using a fresh ubuntu from USB, this light turns on normally.
This may be irrelevant, but the issue started yesterday when I noticed that the trackpoint scrolling that I had enabled using gpointing-device-settings was not working. I ran that app and checked the settings, which were normal. I then reset the computer, and found the trackpoint was working just fine, but I had no wifi. A few resets later, the problem was not solved.
Just installed Fedora 14 from the Live CD i686 on my Dell Inspiron 1521. I can't connect to the SpeedTouch 585 on either wireless broadcom card or the wired Ethernet card.
I can connect to it from the same Laptop on the Vista which is on dual boot on the same laptop.
Further confusing is that I ran Fedora 14 and connected to another SpeedTouch today.
Already checked the Channel on the wireless nic and it's on the same one as the SpeedTouch.
I have lenovo thinkpad, T61 with Intel 4965AGN wireless card. It is a N card, it works under N mode in windwos, but not in Ubuntu (10.10). I installed ndiswrapper and got the windows xp drivers for this card. the issue is that i got an error when installing the drivers and since then I cannot use wireless.
The error i got is: Code: Module could not be loaded. Error was: FATAL: Could not read '/lib/modules/2.6.35-24-generic/kernel/ubuntu/ndiswrapper/ndiswrapper.ko': No such file or director I unistalled the driver, but now under network connections no wireless connections appear, nothing. I cannot use wirless anymore.
Those are my authentication capabilities, obviously. I am using a WEP encryption for my wireless router and according to this, it will not allow me to connect. Is there anyway to allow that? The wireless card works just fine in Windows, even on the same network encryption type. Using a Intel Wireless/Pro 4965 ag. Note* this is my mother's router and whatnot. She won't change it the encryption type.
The problem with my wireless network. I have Dell DV6 Pavilion 2115 eg laptop and i installed Ubuntu 11.4 and internet and wireless worked, until i reboted my system it has disapear. I cant no longer to connect to a wireless network. It dont shows me any wireless network. My wireless card is Atheros AR 9285 802.11b/g/n Wifi Adapter
I installed a Tenda W322P wireless card in my dual-boot PC running both Windows XP and Ubuntu 11.04. The card worked straight out of the box on XP, but does not function correctly under Ubuntu. My apologies for any missing/irrelevant information, I am having to post this from the Windows boot so the Ubuntu settings are not directly available at the same time as internet access.I followed the process detailed here htURL...to install and configure the driver (I believe from reading other sites that this card is the Ralink RT3062 chipset), blacklisted the original RT2860 driver that was in use (couldn't even get the card to scan for wireless networks with the default driver) and restarted the interface.
Since then, sudo iwlist scan can find my wireless router but when I attempt to connect to it, it seems to enter a loop of requesting the WEP key then pausing for a while before re-requesting the key. I know I have the key value correct because it is copied and pasted from the same text file I used to copy and paste into the passkey field on the Windows boot. Attempting to connect to the router using Ubuntu also has the rather unfortunate side-effect of crashing the wireless router, killing off all other device connections until the router has been reset.
have a dell Inspiron 1501 with ubuntu 10.0.4 I want to rename my wireless card from eth1 to wlan0 as I use conkyrc and it will not read my wireless strength or my ssid cuz it thinks it's a ethernet card and not wireless card. I know this for a fact because peppermint os my wireless card was wlan0 and it worked just fine.
I use network manager applet 0.7.1. I had set the automatic wireless connection to my my wireless network (WPA key secured). Recently, I get the following problem: At the automatic connection, I get the message: Network manager applet (/usr/bin/mn-applet) needs default keyering. As I don't know what it is to type it and then, deny or OK, it doesn't get connected to my wireless network.
I just upgraded to natty last night, and everything is working fine except for the network manager. I can enable and configure the wireless card via bash, but the network manager widget will not manage the wireless card.
When I first boot up, the "Enable wireless" check box is greyed out. After I enable the card via the terminal, the "Enable wireless" check box becomes ungreyed, but every time I click it, it instantly unchecks itself. I feel like Currly from the Three Stoogies. Check, uncheck, Check, uncheck.. "Slaps face repeatedly."
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
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 !!
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?
I'm attempting to set up a VPN server on my box using the nifty HowTo posted here: [URL]
My setup is as follows:wifi0 --> Internet; managed entirely via nm-applet (NetworkManager) Where I'm running into trouble is in the creation of a bridge interface (br0) to bridge future VPN clients to my local network.
The guide(s) say that I need to screw around in /etc/network/interfaces to setup br0 and [eth0/wifi0] accordingly. The problem is that when I specify a configuration of any sort for wifi0 (my only choice for a network uplink), it disables nm and I am unable to configure my wifi in any sort of sane way after reboot... Further info: this "server" doesn't move, and always always connects to the same wifi hotspot that is also nailed in place.
I want to buy a wifi card that will, hopefully, be rock stable under my kubuntu 10.04 64 bit. Currently I have TP-Link Atheros card and stability in Linux is horrible. Please DO NOT give me links to compatibility list. Just suggest a network card that is most likely to be stable with least manual tuning effort required.
