My network manager application went missing a few days ago. I enabled it by right clicking on the taskbar above and opting for "show". It reappeared and worked fine. After I rebooted, however, it was there ok, but it doesn't respond to clicking at all. It has stopped working.
View 1 RepliesRight so yesterday my internet worked fine. Today - no connection at all. The light for my cable on the router doesn't even show up. I originally had indicator-network installed, so when the internet first stopped working, I tried a few other options such as tethering to my phone via usb and bluetooth (which I have successfully used in the past). However, these didn't work, and I figured that as connman is still in beta, maybe that was why. So I reinstalled network-manager and network-manager-gnome via a usb stick, uninstalled indicator-network, and rebooted the computer. Still no internet.
When I click on the applet, it says "No network devices are available". This is odd, as I definitely have a network device... it is part of the motherboard. So I thought I'd do the SMARTlan test or whatever it's called. It's part of my BIOS, so I ran that and it returned results that I (kinda) expected: when the cable wasn't plugged in, it returned one set of results. When it was only plugged into my computer (and not the router), it returned another set of results. And when it was plugged into both my computer and the router, it returned a third set of results. So that leads me to believe the cable itself is fine.
And when I move the cable to a different port on the router, nothing changes. The corresponding light still doesn't come on. Network-manager, telling there are no network devices. The BIOS can see the ethernet port and the cable. And the router is functioning perfectly for my parents' computer and my ps3. And I have checked the cable to my computer for physical damage - it follows the same path as the one to my ps3, and on top of that, nothing physical can possibly have happened to it in the last day. This happened once before, except I don't think the network devices were lost.
I am a Windows refugee who discovered Ubuntu as a way to save my files from my virus-ravaged computer. Had no installation discs for Windows, so when I had to wipe my hard drive and start over, I decided to give Ubuntu a try. I've had mixed success, but that's another post...
Right now, the problem is that I installed 10.10 two weeks ago and was able to connect to the Internet with no problems - until yesterday. Suddenly, our wireless network (the only one in the vicinity) does not come up as available in Network Manager. In fact, the entire wireless option disappeared. I know there are many posts and threads on here about this, but weeding through them trying to find an answer is more frustrating than actually dealing with the problem. I know the router works because I can post on this forum from the Macbook. I really like Ubuntu and would like to keep using it, but not being able to connect to the Internet now on top of the other issues I've had is making me doubt I want to continue down this Linux road.
P.S. When I attempted an analysis through System Testing, it said something about there being no proprietary drivers?
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.

View 9 Replies View RelatedI have Debian installed a year ago, working perfectly until last week when network card connected to internet stopped to communicate. I did no change in configuration. It just stopped to work while I was reading an online web page. Network card connected to local network still works fine.
I thought it might be a NIC failure so I installed a new PCI NIC but no change, still no communication throught this NIC.
I verified/changed cable between NIC and the router, no luck. If I connect the same cable from router to a Windows PC, everything is OK. If I connect back to Debian machine, it does not work.
I tried connect this NIC with a different router with DHCP enabled, nothing, NIC will not communicate with DHCP server.
I tried to set static IP, no change.
Today I booted a Knoppix 6.2 and this NIC worked perfetly! It set up using DHCP, I could access the internet.
I booted machine as usual and the problem still persists of course.
This is information captured immediately after boot. The trouble NIC is eth0 after boot finishes.
All this was captured with eth0 connect to a router with DHCP enabled. There is no DHCP entry in syslog related to eth0. Reinstall is the very last option.
I have a laptop, and the wireless and cable worked fine for a while, but one day, for some odd reason, the wireless and network cable just stopped working. I'd connect to the web, and I would get output using "ifconfig" and the GUI wireless signal. When I hook up the wire, it detects it. However, no matter what I can't load any web pages. The wire does work in another house, and my windows partition utilizes these devices well. Any ideas?Additionally, I am able to log into my wireless router and change configurations, but that's about it :/.

I'm not a total newbie, but run into some strange problems with my installation of Lucid.Everything was working fine yesterday. I shut down the laptop and powered it up this morning and had problems with network. I have two NICs (wired and wireless). Both are set to pick up IP settings from DHCP and both do, however when using wired network I can't communicate with outside world - can't even ping the default gateway (but pinging 127.0.0.1 or IP address of the NIC no problem, so stack should be OK).When on the wireless network everything works fine (otherwise I would struggle to write this post ).What is very weird though is that I have a VMWare Player installed and using Windows VM on wired network works just great!
I noticed that when you're persistent it happens that you can ping but huge chunks of traffic are lost (e.g. packet 1-10 would pass, 11-40 would be lost, 41-59 would pass and so on).I restarted Ubuntu, tried shutting down interfaces, disabling networking and nothing helped. I don't recall performing any changes (at least that I would be aware of).Can anyone suggest something?BTW. This is not DNS issue as both IP addresses and FQDNs do not work. When I refer to using a given network (wired or wireless) the other one is down with ifconfig command...
It has been a while and many ubuntu updates since i connected the windows laptop, it used to work fine but this ubuntu machine keeps telling me the cable is unplugged.

I am by no stretch of the imagination good with networking
View 7 Replies View RelatedMy desktop computer has another Linux distro on it. Wired networking was working fine. I wanted to try Ubuntu 10.10 so I installed it on a spare USB HDD. After install, networking still worked on both distros.
I moved the USB HDD to my win7 laptop and Ubuntu 10.10 booted fine. Once booted, Ubuntu asked to configure wireless on the laptop. I tried to do this but it did not work.
Therefore, I moved the USB HHD back to the desktop and booted. Now the wired network does not work from either Ubuntu or other distro (fedora 14). And to top it all off, the wired network will not work even from the Ubuntu live CD.
I have checked all connections, switches & cat5 cables to my desktop computer. I can still access the network and internet from my laptop (in win7) so I do not believe it is an infrastructure issue. I can confirm that everything works from the cable out of the back of the desktop through to the internet.
Here is the output from the usual troubleshooting commands in Ubuntu 10.10 code...
Network stopped working about a month ago. I installed ubuntu again, and network worked fine, and I turned off updates to keep things stable. Now network stopped working again. No changes had been made to it.I put in the ubuntu install cd, and network works fine off of it. I did not reinstall again. ifconfig shows eth0 with correct ip address, but 0 RX/TX packets.
Cant ping anything from it, and cant ping to it from other computers.I'd really rather not reinstall yet again, any ideas on how I should go about diagnosing this problem?Ubuntu 2.6.35-28-generic-pae #49-Ubuntu SMP Tue Mar 1 14:58:06 UTC 2011 i686 GNU/Linux
I have somehow messed up my network (onboard) card in the process of configuring network settings. how I managed to do so is that I did not use ifdown before making changes to my "/etc/network/interfaces" file. Also I think it might be relevant to mention that the sshd was running -although with no active connections at that time- since I have the service installed on my 10.04 Ubuntu Server (x64). So step by step what I did to end up with no network connection:
1) sudo cp /etc/network/interfaces ~/myfiles/interfaces.original
2) chmod 444 interfaces.original
3) sudo nano /etc/network/interfaces and then applied my network settings (IP, netmask, etc.). The syntax and configuration of my "interfaces" file is without flaw since it was simple, typical and was assigning my up to then DHCP assigned IP of 192.168.2.3 to static.
At about that point and although "ifconfig" showed the changes had been applied as planned the network card stopped working. I could no longer ping anyone but myself and the leds both on my network adapter and on my switch were turned off. Since my configuration also has a Windows 7 installation I rebooted to Windows in hope of troubleshooting through device manager but I got an error code 10 which means that the adapter could not start. Did I fry my network adapter for good and for all or I still have a chance of repairing it?
PS: After a closer look I saw that the NIC's LEDs indicate that the device cannot start. I am considering to reboot my MB as a last resort since the NIC is an onboard device and changing BIOS settings has done nothing to restore it.
So I just did a fresh install of CentOS 5.3 and ran an initial update how ever I cannot get the network manager to start. I found this page on the wiki - [URL]? highlight=(networkmanager) But when I try to run chkconfig NetworkManager on

Came back hour later was done, said it needed to re boot, so I did. From then on, no internet, not icon, no Network Connection in the drop down list for preferences.
What I have tried:Worked off live cd, again, all works fine, icon, manager, internet all there.In installed version: In terminal, typed service Network Manager, it said unrecognized service.Did yum install network manager. It started to do it, but looked like it was trying to get stuff off mirrors, and of course there is no internet access. error PYCURJ ERROR 6.Of course I can re install, but I figure I will just end up in the same place a few hours from now.

Since an upgrade from 10.10 to 11.04, all wireless devices for me in the plasma network manager applet are not functioning properly on a Dell Latitude E4310. Specific problem: No wireless networks appear in the plasma network manager applet. Manually-configured networks do not connect. A separate CDMA card appears, but cannot establish a connection. The CDMA card does function on 10.10 machines, and formerly worked on this machine. The only wireless 'network' that appears in the plasma network manager widget is 'hidden network'. Manually adding a network and checking "Connect Automatically" does nothing. I attempted a fresh install after the upgrade itself failed the work. There are no networks to click on, and selecting the device itself merely shows the status page.

I'm running Kubuntu 9.10 (Karmic), and my System Monitor (a.k.a. Task Manager) has stopped working. I had been using the graphical version of the app because it was easier and faster for me to deal with. I know that there is a command line solution for this, but I also know it involves having to know the task number of the program I want to kill (I've got a game that I love to play, but only closes cleanly about 10% of the time). I've posted a couple of screen shots to show the errors... The first one is the error message itself (I have to hit 'OK' on this twice to clear it), and the second one is the resulting empty window of the System Monitor
View 5 Replies View RelatedI did a clean install of Ubuntu 10.04 on a Toshiba Satellite, Intel graphics card, a few days ago, and had no trouble accessing the CompizConfig Settings Manager. I changed a number of settings, and everything seemed to be working just fine. But two days ago, I noticed that the compiz effects (rotating desktop cube, minimize effect etc.) were gone; and when I now try to access the Settings Manager, I see a "Starting CompizConfig..." appear in the panel and linger for about five seconds; then it's gone. No settings manager, no error message.
The day that happened, I had (to the best of my memory) not installed any updates. I had, however, removed a bunch of applications through the Software Center. I had also launched Ubuntu Tweak and changed a couple of settings. The only option it showed, and shows, under 'Compiz Settings' was then (and still is): "Prerequisite Conditions" : "Install Advanced Desktop Effects Settings Manager". The box was checked. I have since unchecked and re-checked it, thereby uninstalling and re-installing the settings manager. But that hasn't changed anything.

Moments ago I was using, as always, my bluetooth devices on my Macbookpro4,1 and suddenly the icon disappeared and my devices disconected. I thought the daemon just crashed so I tried to restart but I got a command not found error. I opened the Bluetooth preference dialog and it said that no bluetooth device was present on the system. I restarted and same result.
As a last measure I completely pruged bluez and gnome.bluetooth and reinstalled. Same result.
I have posted this in networking, but perhaps it should have been here. Can anyone give me a clue on how to get my networking to work again? I don't care about sound.Last night I was trying to get my printer working, and when I rebooted, I lost networking and sound.I am currently booting on a live CD, and sound and networking are fine-- so it can't be a hardware issue (obviously). I must have inadvertently broken something, but I can't figure it out.
I have tried restarting networking, but it doesn't respond-- it says stop/waiting or something like that.I can't access the sound preferences-- it says waiting for sound to respond (or something like that).When I reboot, sometimes I see a terminal window with the same line scrolling very, very quickly-- something about waiting for USB.Additionally, the system is very slow to respond-- clicking a menu item can take a long time for it to appear, etc.
After 2 years of good service and after I've changed IP addresses in the router from 192.168.1.2 to 192.168.1.102 my autofs stopped mounting my NAS with NFS. That was the only change.
View 8 Replies View RelatedWhen originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.
Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.
I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.
I got to the prompt in the subject line. Then I typed grep /sounds/ and return.Then the program stopped responding to commands. I could type things, but nothing happened. Not even when I typed kill -9 and return.Why did the thing freeze up? I don't think there is folder /sounds/.
