I'm using Fedora 15 with KDE, and in the NetworkManager settings I can't set my Ethernet connection to be a System Connection. The box is greyed out. I assume only root can enable this option, but GUI apps typically ask for an administrator password. I did add my user to the "Administrator" group when I installed and I can use sudo and all that.
View 2 RepliesAfter some wonderful days with fedora with my CDMA mobile internet connection (the only connection where I live) NetworkManager can't connect anymore.
I tried to delete the settings and rewrite them without success.
I have A Novatel Ovation U720 CDMA/EDVO USB modem.
I can connect with wnXP and kubuntu, but can't connect with fedora anymore.
I wish to make the definitive move from kubuntu to fedora... but I should wait.
The symptom is that NetworkManager repeatedly ask for password to connect to my AP.My AP is secured with WPA-PKI. The problem even happens with Fedora 11 live cd if I'm not quickly configure wireless connection using NetworkManager right after Fedora completes booting up. It means if I promptly configure wireless connection, i'm still able to access Internet. Same thing happens for the first boot of Fedora from hdd. For the second boot or when I dont quickly configure wireless connection when system finished booting up, NetworkManger repeatedly asks for password for AP.
I did try several approaches posted in this forum but problem still persisted. Some of approaches I tried are:

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.
Ubuntu desktop 9.04 Whenever I try to copy files to any machine on the network, the transfer stops and I no longer have access to the network or the internet. This happens whether I'm doing scp, copy with the gui, when copying to windows machines, and when uploading database files with phpmyadmin. I have been able to successfully transfer large amounts of data outside of the network via ftp, but not to any on the network. I've discovered that I can re-enable network access by restarting NetworkManager.
View 1 Replies View RelatedI 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
I'm using a Lenovo B450 laptop with Fedora 14 x86_64. The laptop has a Atheros AR5001 wireless adapter and is identified at lscpi.
Additionally lspci reports that the kernel driver in use and the kernel module for that device is ath5k.On a fresh install of Fedora 14, the NetworkManager applet seem to behave well at enabling and disabling wireless (remember the "Enable Wireless" checkbox). Though wireless was always at disabled state at every boot time, even if it was enabled at the toggle button on the laptop. Now that, after I have fully updated the system (yum -y update), I'm unable to enable wireless. Clicking on the "Enable Wireless" menu item on the NetworkManager applet has no effect, and I've a confirmed report that the update broke this functionality (I reinstalled F14, and then it was working, full system update broke the function).After the update, the kernel version is 2.6.35.10-72.fc14.x86_64 and the NetworkManager version is 0.8.1-10.git20100831.fc14.x86_64.
As I reported in this bug:[URL].. root is not able to start an openvpn-connection via the "nmcli"-command to control NetworkManager, whereas my user does not run in any problems with this command. My error output when starting as root is as follows:
Code:
# nmcli con up id "my-openvpn"
Active connection state: unknown
Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/5
state: VPN connecting (need authentication) (2)
Error: Connection activation failed: no valid VPN secrets.
Does anybody know what to do about this strange behaviour? The vpn-secret seems to be stored in the gnome-keyring and in the /etc/NetworkManager/system-connections/my-openvpn simultaneously. But root cannot access any of these. Why this is important? I'm trying to set up a dispatcher-script to automatically start openvpn on eth-connection. but this does throw the exact error from above (no valid vpn secrets..).

i'm realatively new to linux am just getting my head around the command line, any way my problem today is, my network connection and networkmanger program have been deleted/uninstalled after i did a system update. im running ubuntu 10.04 32 bit. I have run of some commands which should be able to tell you whats going on. at the moment i'm using a live ubuntu cd to gain net access.
so the question is How do i restore my network connection and get my networkmanager program back without a internet connection. (i can download stuff to a memory stick and do manual install) Hope someone can shed some light on this, i know this topic has been covered before although each case seems slightly different to mine.

I'm running Ubuntu 10.04.2 LTS and from time to time eth0 connection is lost.
Looking at syslog (below), if its a hardware (network card) problem or a software bug?
syslog file:
I installed all the necessary packages for the networkmanager-openvpn function to function. The openvpn-connection-setting are successfully imported into the networkmanger via the conf file but the apply button is grayed out, so that actually saving and using the connection isn't possible? Does anyone know, where the problem is? It's a fresh install of Ubuntu 10.10 after the upgrade from 10.04 sent the networkmanger down the drain.

According to [url].
After a bit of fighting interface works I can ping any domain name or ip address. I can even connect to web server via telnet, for example telnet www.org 80. I can see the response from Web server, but Mozilla says that it is offline, System Update says that no connection.
What can be the problem if manually I can connect but any Gnome GUI program says you are offline?
How can I enable the network with Networkmanager WIHTOUT logging in in OpenSuse 11.2?
If I define a connection for ethernet the System connection is greyed out. I want to use Networkmanager because I have also wireless connections...
enable WPA encryption on my wireless connection? Wireless networks are detected and listed, so the wireless card is functional in the most basic sense, however, when going to connect to any particular network,I am not given the option of entering a WPA passphrase, only WEP, and as my router is set to use WPA, this is a problem.I am trying to get this going on a fresh Karmic install on a Toshiba A15-S157 notebook.Thus far, I have found this: https://bugs.launchpad.net/ubuntu/+s...ux/+bug/315489 which would seem to relate to my problem.I looked in my logs and saw this entry: Jan 10 16:06:35 cody-laptop firmware.sh[863]: Cannot find firmware file 'agere_sta_fw.bin', and have since found that file, and have downloaded it to my desktop. It seems like this may be the solution, but how to exact it, therein lies my (momentary) problem.

my laptop has a proprietary Broadcom STA wireless while in live CD, I can go system>administration>hardware drivers, and activate the driver however, when I have ubuntu installed into the hard drive, and go to system>administration>hardware drivers, ubuntu attempts to connect to the internet to look for the driver and fails I can't find the option to choose the driver in the computer. I even inserted the live CD into the disc drive, and still no luck. How to install the wireless driver without wireless connection? Is it possible to install the driver manually?
View 9 Replies View Relatedi downloaded ubuntu 10.10 for learning purpose. All goes well, i installed it successfully. The problem which i face is that when i connected my mobile broadband device, ubuntu detects it and i have succesfully made the connection. But the network Manager is showing "disable" Mobile Broadband connection. I tried to put a check on Enable Mobile Broadband but can't check it. So i can't access Internet in ubuntu. I think some offline package installation should be there to resolve the problem, or some console commands. I tried to use the (wvdial) which i use at Backtrack. but i think ubuntu did not have.

View 5 Replies View RelatedI recently installed Ubuntu 9.10 on my Dell Inspiron 1545 64-bit laptop. Before that I used Windows7. In Windows, the internet connection worked perfectly well. But after installing Ubuntu, I am unable to connect to the internet. The network-manager applet finally says that "You are disconnected". When I do the "ifconfig", I got no IP address.
So, I installed Ubuntu 9.04 in the same system. But the problem persists.
I gone through many posts in this forum but nothing was useful.
I have no problems seeing the networks available and connecting to a network in KDE. But there is no network manager in GNOME. I might have messed up with the settings earlier. What I can do though is run knetwork manager every time I start up (or add it to start up programs). But that opens up the KDE wallet which would rather avoid.I am thinking I need to install something related to NetowrkManager.
View 2 Replies View Relatedif the NetworkManager uses wpa_supplicant? I normally dont use NetworkManager and decided to try it. I started it and tried it out and it works with WEP and WPA! I cant figure out why using the iwconfig command is not working by itself for WEP. WPA working with NetworkManager is just a bonus though.

If I boot with the NetworkManager service enabled, my NIC presents as expected at /dev/eth0 (I'm using biosdevname=0). However, when I stop the NetworkManager service, /dev/eth0 disappears from the filesystem.If I boot without NetworkManager enabled, /dev/eth0 is never created. Reviewing dmesg, udev is loading an ethernet driver.

Yesterday I was lost, I updated the drivers for the nvidia card and that broke X, since my internet is not up and running when booted I was wandering how to call it from the command line since that was the only thing I could see.
I loaded F10 up on my laptop a few nights back. NetworkManager connects via Ethernet just fine. It will also connect wirelessly, but only when security is disabled. I've been using 128-bit WEP.
When I try to connect using security, this is what appears in the log:

after fiddling around with compiz-fusion and KDE, my network suddenly disappeared. I looked in the package manager and apparently I don't have the gnome applet for networkmanager...but everything else I seem to have (the git version not svc or w/e) Anyone know if installing the applet will let me choose my wireless network and connect to it? Right now I think so, but what I have to do is boot into windows, find the package on the web and download it, then boot into fedora and install it
where I can find the fedora 10 networkmanager-gnome package (git version for x86_64)? I looked around and found the svc version and a git version for i386, but my OS is x86_64 and I couldn't find any git versions of it for 64-bit fedora's. btw, I have no idea what git and svc mean, but when I tried to install the svc version, it told me I had to install svc versions for all the other networkmanager packages...
I recently installed F10 x86_64 on my Lenovo T61 laptop, and while I'm quite pleased with F10, I am having a difficult time with my wireless card. I spent most of yesterday searching for a solution, but none have presented themselves. Scenario: I am trying to connect to a HIDDEN SSID with NO ENCRYPTION (work Wifi, don't ask) using network-manager and its associated applet.
Symptoms: I left-click on NetworkManager, select "Connect to Hidden Wireless Network", enter my information, NetworkManager does a few things, and finally I'm told that NetworkManager cannot connect to my network.

I have just installed Fedora 10 on an old laptop and was quite impressed with how smoothly it all went ... until it came to setting up networking!
I have battled for three days now and I'm almost there;
- installed updated firmware to the built in Broadcom 4306 wireless network adapter
- got NetworkManager to work with a static ip address by manually editing the ifcfg-wlan0 file
- managed to get the WPA security to work
The only problem I am left with is that there is no default route; if I set one up using: ip r a default via 10.1.1.1 dev wlan0
Then everything starts working.
If I try to add routes using the NetworkManager gui interface they dont get saved (no suprises there then! ).
I have tried creating a route-wlan0 file in /etc/sysconfig/network-scripts/ but this seems to be ignored by NetworkManager.
Since the NetworkManager GUI is almost useless, does anyone know if there are any other configuration files I can manually modify to get a default route set?
Just upgraded from Fedora 10 to 11 and cannot setup wireless connection via NetworkManager. By some reason it doesn't store WPA key. There are following errors in the message log:
