Ubuntu :: Network Manager Is Not Working Anymore
Mar 1, 2010
I'm a newbie in Linux (ubuntu) environment. Well my prob started as I tried to install several w-lan applications. I tried them out and deleted them again. Till (I don't remember the name of the prog) I finally shoot "network manager". I tried some things like:
Second installation of ubuntu to get back internet.
Downloaded some deb files and installed them in off-line mode.
But it doesn't work because some not satisfiable things happened now I tried to fix over USB live to fix it no chance. What I need is a possibility to install from USB on my first system or boot system one and USB on the same time to use the internet per switching or something like that. Maybe it's possible to update my system wile the USB system is running? Or is there a possibility to use the ubuntu CD and install all needet packages from there because network manager is already in Ubuntu. I think that all OS company's have to think about that , when they deliver a OS that you can choose or afterwords reinstall progs from the original source ...or what?

Config: Squeeze, 2.6.32-5-amd64I just installed squeeze and the network is up and nm-manager deamon if working but the Gnome applet doesn't seem to work as usual. It indicates no network although the network is available as indicated by ifconfig and route below. When I switch WiFi on, the nm works flawlessly. When I click on the applet icon it says "Wired Network: device not supported" (or similar, msg in french is
eth0 Link encap:Ethernet HWaddr 00:1f:e2:12:ea:d8

this is with both network manager and WICD, a problem i've had since i got ubuntu - multiple wipes and reinstalls the wifi is supported out of the box, the problem i've randomly run into since installing is, it will randomly stop detecting networks "no networks detected"
i've noticed over time as this as been happening, that it usually happens whenever there is a high load - multiple videos going on multiple tabs, videos queued up etc. its never happened during regular browsing - theres always a lot going on when it happens, almost like it collapses. the only way to fix this, is to quit the manager - shut off the computer (restarting doesnt work) and then it comes back after

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.

Right 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.

Fresh install of Fedora 14 from Live cd.Used it for an hour or so, d-loaded some programs, had ti all running great. Wired connection to internet. Had the Network Connection Manager icon in panel. There was an icon saying new updates, alot of them, like 400 or so. Told it to go ahead and up date, left room. 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.

Neither the CDMA card nor any wireless networks are working. If I take the exact same machine and boot from a disk with 10.10, both work.

I've been dual booting Windows 7 and Debian on my desktop ever since. But recently I installed Debian again on a new laptop that I recently bought and unfortunately it's being very different from my first successful installation. The first problem is that Network Manager is not picking up internet on the new laptop. The Wireless tab is grayed out, so I can't click it and look for a new one. I've been using Wired internet since, but if I want to take it to work I have to have it be Wireless-able. Currently my Wireless Card is a Broadcom 4313 802.11 b/g/n which I'm fairly sure is supported. The second problem is installing Firefox. On my first installation it worked fine, and the bin file loaded and everything. However, for this second one that's been a completely different situation and the bin file hasn't worked (by this I mean I can't double click it to open it).

I had trouble connecting to a wireless network with openSUSE, so I tried the YAST network manager to see if that fixed it. Not only did it not fix it, but now I cannot connect to any network, wired or wireless. I tried to open the default network manager and it said "Network management disabled". How do I re-enable it?I also have set YAST settings back to their originals with no luck.

I have searched around a bit for a knetwork manager issue I am having on my opensuse 11.2 32 bit install. My wireless card is an 04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01) I am currently using the Broadcom wl driver
I am on the Internet with this machine as I am typing using the older "ifup" method. I am having great difficulty connecting to the Internet when I use knetwork manger though. The strange part is when I am connected to my router with knetwork manager, I can log into my Router, but I can not get to any web-page/ping any outside address.
so far the best (I was able to locate) advice I was able to get is located in this post. < Broadcom wireless, partchy internet - openSUSE Forums > following a posted how to to disable IPV6 (I suspect this may be the issue??), I was unable to locate modprobe.conf, or modprobe.conf.local, even after I updated via updatdb. I gave a shot at entering in "disable_ipv6=1" into "menu.lst". However, this did not solve my issue with knetwork manager. If my network information is needed when I am "connected" utilizing knetwork manager

I installed Burg and it worked for some time. I installed some apps that I can't remember anymore and closed my comp. I restarted my computer today and Burg does not work anymore, Grub just start like before. I tried to reinstalled Burg and it changed nothing. When I check Burg-emu it shows me the right thing, like if Burg was working. Did it happened to somebody else?

It started with Update Manager constantly recycling and not updating. When it starts it shows 295 files and 308MB waiting to download. When I click on 'Install Updates' it appears to go through the process, and then presents me with the same 'waiting to install' window again - and again, and again - in fact as many times as I care to click the 'Install Updates' button. No error messages appear. The 'Settings' button produces the same apparent process as the 'Install Updates' button, but doesn't present me with any other screen.
I've tried all the solutions I could find on these forums and nothing works. The sudo suggestions for Terminal usually produce error codes. adjusting a line in the 'hosts' file. When I tried this I was presented with the obstacle of not having access to the read-only file, and no matter how much I searched I couldn't find how to gain access . While investigating all these possible solutions, I was directed in turn to the Software Sources and Synaptic Package Manager applications, but when I attempted to start them, 'Starting Administrative Application' appeared briefly on the taskbar - and then disappeared!

You really have to love this fantastic Ubuntu system which destroys your setup and programmes with an update.
It seems as though one of the updates made a mess of Skype this time. well done.
Ok so here is what's happening.
First i have to say that to get my sound card working i needed to upgrade ALSA. Everyhting was running fine until....NOW.
I haven't used Skype in a while but now i thought lets use it a bit. I start up Skype there is sound. but then suddenly sound is gone. video is just fine. sound is gone completelly from Skype. mic doesn't work and neither do spekers, eventhough upon launch everything works. i can't even do a test call. in fact i could do it once but the sound was messy.
also the skype seems to have crashed as i can't exit it at all. it's just keeps running as process.
anyone had something similar? any solutions? i would post this on Skype forums, but since Skype worked before and now it doesn't anymore i believe it is Ubuntu issue.
I am running Ubutnu 10.04.

I have an HP dv4 1313dx, pavilion notebook computer. The Built in webcam seems to work OK, but I have absolutely no sound registering when I speak over webchat , or over just sound recordings when I talk at the computer. I'm not sure if it's a software issue or not. I upgraded to 10.4 beta because 9.10 wouldn't let me run my wireless card. So upgrading to the new beta version solved that, but as I said I noticed the built in mic on my notebook isn't picking up any sound. This is whether I'm using Skype, sound recorder, or AMSN for webchats.

In Lucid I cannot get CPU scaling to work anymore, in previous Ubuntu releases this was not a problem with the same hardware (AMD Phenom 9500 Quad). I used to load module 'powernow-k8' and 'powernowd' to make it work, but it seems 'powernow-k8' is not available in Lucid. Anyone who has cpu scaling working in Lucid?

On my Sony Vaio VPCF12M1E I have a small but irritating problem: Since yesterday the numeric pad on my keyboard doesn't work anymore. I can use the numbers at the top, but not on my numpad. This happened out of nowhere when I was just setting up an access point. No idea what I did wrong, cause I only configured a static IP Reboot, and numpad was gone. I tried restarting the laptop, I tried disabling and enabling Numlock over and over again. Nothing works.

I have been trying to lighten the load that Ubuntu uses on my RAM and processor, and decided to try LXDE, as it is the lightest-weight DE that I have tried and liked. I noticed I didn't have any wireless connectivty under LXDE, so I checked the LXDE site for the solution, and it said to download and install LXNM, which supports wireless connections. Unfortunately, installing LXNM (apt-get install lxnm) also uninstalled nework-manager, and network-manager-gnome, on top of lxnm not working properly, and stranding me without any way of reinstalling the OS, and without an internet connection (I can't connect with a wired connection, either). Is there anything I can do, aside from reinstalling?

I was able to successfully install Tweetdeck and Adobe Air using the instructions here: http://www.technixupdate.com/install...-ubuntu-linux/
BUT after I closed the program, when I tried to re-open it, it wouldn't load anymore. It would show that it is "Starting Tweetdeck" but it would not lead to anything - it would just close.
So I tried to uninstall everything and re-install from scratch. But the same thing happened - the program would not load.
I tried to isolate the issue by trying to install another AIR application. When I double-click on the icon or click on install using Adobe AIR, it would not run. So that only means that the issue is with Adobe AIR.
Here's what I did code...
It will then load the installer. Go through the step-by-step process until it's finished.
Install Tweetdeck again (Just double-click on its .air file).

Earlier I was in windows to do school that I had to do in windows. I shut my monitor to suspend my computer, which disables my sound card. Later on I went back into ubuntu and forgot about it. Ubuntu had updates to the system and since then I have not been able to get my sound to work.

This thread belongs in 'Networking' probably but that category seems to get less traffic.
Perhaps the mod will move it there after some discussion is generated...
