Networking :: 10.04 - Network Manager Icon Suddenly Went Off
May 24, 2011
I have been using ubuntu 10.04 LTS for the last 5 months, used tata photon plus for networking. Everything went fine when couple of days ago, after doing normal updates as listed by the update manager, sound went off.. to solve this, I had to remove and reinstall certain packages as listed in [URL] ...+documentation, I had to restart, after restarting, the sound problem was gone but the network manager icon went off, the modem was not getting power from the computer though the LAN wire was connected. To add to dismay, the mobile broadband connections that I had added to the network manager were gone. I tried adding the tata photon plus (huwaein) again but could not be added, reinstalled usb-mode switch data and related packages, but still the computer does not detect the photon as usb device. I have broadband dsl connection and tata photon plus too but cant use any of them.
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.
I thought to uninstall Gnome Network manager since it was always asking for to connect with wireless internet but it was working fine with wired internet.I uninstalled it and installed wicd. and then for some unknown reasons the internet disappeared.Kindly let me know How can i get back network manager without having internet and make internet work on my computer.I did searched a lot on Ubuntu forums using somone's else computer but no success.So if you let me know how to approach the problem in right manner it shal be great .
(Ubuntu 10.04)I've been struggling for over a week now to get the network-manager icon back in the notification applet. I don't exactly know how and when it disappeared, but I have not been able to get it back eversince. I need it to start a VPN connection.To be clear:- The notification applet is running (battery icon etc is showing)- Network manager is running- Wireless connection works flawlesslyWhat I've tried so far:Solution 1 (did not work)
After a recent dist-upgrade I have lost my network.There is no Network manager icon in the top corner.My switch and the RJ45 port on the PC are both lit green and connected. There is an internet connection from the other PC on the LAN.I am now able to ping the other PC on the LAN but still no internet!My router is at 192.168.0.1 so I have also tried:sudo route add default gw 192.168.0.1.
Using Ubuntu 10.04 (2.6.32-31)on a Dell studio today.Update manager offered four updates, one about networking. I accepted. After restart the Network-Manager icon had vanished from the tool bar and was replaced by a second loudspeaker control icon. No ability to link to the internet. Starting Network-Manager from the pull-down menus did not help.Muggins Noob thought, un/re-install Network Manager. Duh! Uninstall is fine, but re-installing from the web without Network-Manager, tricky. Sadly no ethernet wire available, either wifi or GSM/3G.
I am using ubuntu 10.4, network icon to manage wireless disappear suddenly.Wireless is working fine. I just don't see network-manager icon.I tried:Right click on pannel and try to add Network Manager. But there is no network manager.I also try, $killall $nm-applet, then $nm-applet --sm-disable.
I deleted all APs in my Wireless Section of network manager. After that, the whole network manager icon disappeared. I added the icon back on the panel, but I don't think its the right one. It doesn't do the two green cicles thing when I connect my ethernet wire in. It also doesn't show any wireless AP when I left click on the icon. It doesn't even have an X mark on the bottom left of the icon when no network is detected
I recently installed fedora 15 on my computer but I have a huge problem. I can connect to my router wirelessly for a couple of minutes only. Afterwards my computer has no Internet connection although the network manager and the icon on the upper bar says that i am still connected. I tried editing the /etc/rc.local and /etc/resolv.conf as mentioned in other posts in here bit no luck so far.
language-pack-en, language-pack-en-base, language-pack-kde-en, language-pack-kde-en-base, libsoup2.4-1, libsoup-gnome2.4-1, pm-utils today on my laptop. Some hours later, I had to force the computer to shut down by pressing the power button, since it got totally lagged when I started it after an automatic sleep due to no power left. I started it, logged in and saw that the network manager was unmanaged. I got that message when I clicked the icon at the right-bottom bar.
So, I tried with "ifconfig" in a Terminal, as root.Therefor, I did "sudo ifconfig eth1 up", and the same with eth0. The network manager did not work anyways. I killed it using "sudo killall -9 knetworkmanager" and started it with "knetworkmanager" from the Terminal. The icon got removed and it appeared again, but nothing changed - it said "network manager disables", as before.I logged off and select "Restart X server" from the login screen. I logged in again and tried. Didn't work. When I restarted my computer I saw that eth0 and eth1 was down again. I took them up and then I checked the hardware settings. I saw that I could use either KNetworkManager, Fake Net or Wicd. I tried to locate if I had Wicd or Fake Net installed, but I hadn't.
Neither the wireless or the wired connection works now. I'd like to know how to fix the Network Manager, or whatever is wrong. Also, I'd like to know if I can install Wicd using a CD or something. Maybe Wicd works better, I have no idea. I'm using Kubuntu 10.04, the final release.
I am using Ubuntu 9.10 32bit. I removed the network icon from my panel & I would like it back now. How can I icon back? I use the icon for my wifi networks.
I am using Ubuntu 10.04 Lucid Lynx 32 bit version alongside my Windows OS.I wanted to enable my DHCP configuration in my modem.So I did what was to be done from Windows and when I switched to Linux, I found DHCP enabled connection not working in Linux and also the network manager icon had vanished from the systray.I have now switched off DHCP and wanted to revert back to my original settings but still no network manager icon is there.
My Network-Manager icon used to show as a diagonal line with a ball in the middle, now it shows as an Up-Arrow-next-to-a-Down-Arrow. Anybody know why the icon has changed? Is its appearance controllable by me--can I change it back to the old icon display?
As the title says after upgrading all packages in ubuntu 9.10, network manager icon in notification area is missing, I've tried deleting and adding notification area to the panel but no luck there.
The small icon from the top bar which allows me to choose which network I connect to, as has a bluetooth icon that was there. I don't know how it's gone but I've had no success in making it re-appear. Is there something that I could put into a terminal (i.e. a magic spell!) that would make it re-appear.
I have had a bit of experience with previous distros but I am pretty much a newbie. So I setup 10.04 but I can't get my net to connect. It's working fine on Win7 (posting from it). It's a dsl connection. I use an ethernet wire to connect to the net.
I opened terminal and used the 'sudo pppoeconf' command and followed the instructions. This is how I used to get my net working on previous distros but it dosen't seem to work in 10.04. The terminal says that my connection is active but it isn't. The network manager icon isn't visible on the top panel.
Network Manager icon aint showing, neither is the power manager. Im using "alt+f2" the nm-applet to get the NM work but removes after reboot, so i have to do this all time.. uhm, when trying to enable desktop effects is sats "searching for available drivers" and then "Desktop effects could not be enabled". When trying to install apps from Software center, neither of the apps installs, the button install just keep refreshing, but if i go terminal: sudo software-center im able to install everything.
Just installed (clean install) of Ubuntu 10.10 on an old desktop pc. The network manager icon is missing, Buy the way i had to run install from safemode. As I was having problems with login in, I kept trying to login in to the normal desktop but Ubuntu kept thinking about it for approximetly ten seconds and then asking me to login in again repeatedly. however when i switch to guest user on the guest desktop the network manager icon appears. I have used this icon to enter a mobile broadband account and to connect up to and down load all updates surf etc.Read a number posts and find this problem with the network manager icon are quite common. On the main (problem) desktop i have Tried installed a new panel but unable to add the notification area can add other icons Tried adding the notification area to the old panel get brief white flash on panel Removed the other icons and reinstalled these icons and tried adding the notification area.looked at "!nm-applet-sm-disable" appears ok
In my top bar (where i also have the, bluetooth, sound time and date and so on icons) i have lost my icon to manage my network. Wired, wireless and VPN. How do i get it back?
I installed ubuntu10.04 on my Copaq laptop. I configured net on it. After some days, thte network manager icon in the panel suddenly disappered. how to recover network manager applet icon?
I haven't got Lubuntu as such, I've installed LXDE to try it out with Ubuntu 11.04 sometimes. For it to be practical for me I need the battery icon and Network Manager on the panel. I'm assuming this can be done easily enough as Linux Mint LXDE has got it, or Network Manager at least. i need NM to easily start my Mobile Broadband dongle's connection.Also, can touchpad tapping be turned off in LXDE, and how? I have it set up to have no tapping in regular Ubuntu but this is undone when I boot LXDE.
My family uses a computer running Ubuntu 10.04. We each have a separate login. This computer connects to the internet via wifi.
A behaviour which I have noticed is as follows - the first user to log in gets the network manager applet icon. So they can control the network connection. Any other user that subsequently logs in does not.
Now this is a real pain in the butt as sometimes our wifi connection drops and I might have left my wife logged in and used the 'switch user' function to get access to my login. The only way I can access the applet is by switching back to her login.
Is there any way to make this appear in everyone's login's at the same time?
3 computers in the house run various windows based programs and everything is fine with them connecting to the internet as far as putting in the security password to log in and get online.My old back up computer that I use in the basement that has Ubuntu 9.10 was working fine with the secured network situation up until today.I booted up the computer this morning and it automatically connected as it typically does and I was reading some email and then the computer froze, which on rare occasions it does.
Upon reboot I got a window that asked for the password for the Network Manager Applet which I supplied and then it asked for the password for the secured internet connection which I supplied.It would not connect. After numerous tries of disabling the wireless and enabling the wireless and entering the Network Manager Applet password and the secured internet password I still get no connection.
I notice that when it is trying to connect, the window comes up on the screen that shows that there is reception from the modem, but there is also a little "lock" icon like I'm locked out of the connection.I finally found a way to get rid of the Network Manager Applet password problem but that still didn't alleviate the connection problem.
I have three computers on the network, one is using Windows Vista, one is in an office room using Ubuntu 10.10, and one is in the living room using Ubuntu 10.10. All three computers have folders shared, and were all three reading files just fine with one another for a couple of months. To share the folders, I just right clicked on them, selected sharing options, and checked the boxes for "share this folder" and "guest access". Both Ubuntu computers have samba installed and configured so the Vista computer can see their shares. Tonight, the Ubuntu computer in the living room stopped being able to see the other computers under places -> network. The other Ubuntu computer and Vista computer can still see each other's shares just fine.
I also created a test share folder with a file in it on the living room Ubuntu computer, and it can be seen by the other Ubuntu computer. I can ping the computer in the living room, and the computer in the living room can ping the other two computers. I set a static IP address on the Ubuntu computer in the living room to rule out an IP address conflict. Under network, if I go to "go -> location..." I'm not quite sure what to type in there to find other computers. Under places -> network, the only thing that comes up on the Ubuntu computer in the living room is it's own shares. I tried using the search feature, but was unable to come up with anything resembling my particular problem within a reasonable amount of time.
My problem is that my wireless network traffic sometimes just stop.Like when I tries to update my system, update NetBeans or just download using Uget. I have no clue on what's wrong,Here is my system info:
I'm facing an odd issue with my Ubuntu 10.04. So, I have WLAN activated and working on my user account. Then I switch to another account on the same computer and nm-applet tray icon disappears! I have activated the option that all users may use the WLAN connection, but the tray-icon doesn't show up for other users. Only the one who logs in first sees it. Network connection is working properly, but the tray icon would be handy.
Trying to start nm-applet manually in terminal results in an error saying that nm-applet is already running (sure it is, on the first account that logged in). But is it possible to have the tray icon visible for all users?
I have two wifi routers. If I stand next to the main one with my laptop I can connect and access the internet no problem. The other router is in my office, and the bridging is messed up, so while I see the essid and bssid using 'iwlist scanning' and nm-tool, I can't connect to it.
Now, my main router's signal still reaches to my office, just not as strong as the borked router in my office. I need to be able to choose which wifi network to connect to without wasting time walking between rooms. I added entries for both in network-manager, but it doesn't show them in the list when I left click the tray icon! How the do I connect to the network I want?
