Ubuntu Networking :: No Network Icon In Panel - Switch Users
Nov 8, 2010
Have a strange problem with the network icon on my laptop.
I have two users (me & my wife). We often log in and use switch users so we're both logged in at the same time.
Whoever logs in first will get the network manager icon in the top panel, and whoever logs in second won't get the icon.
The second user does get a message (growl notification?) saying the wireless network <whatever> is now connected & it is indeed connected.
It's a bit annoying, as if I log in second, I can't chnage my wireless network to the other one we have, I'm stuck using whichever one my wife selected.

Ok So i installed edubuntu yesterday, and it was working flawlessly. Now suddenly the "Network Connections" icon in the top panel, to the left of clock and at the side of volume controller is missing. I don't know how to connect to my DSL Broadband internet!I'm using the "sudo pppoeconf" command temporarily to connect to internet. I've BSNL broadband internet connection, I live in India. Please help me how to bring back the networkconnection icon, so that i may connect net again. Like in the above picture, there are "2 oppositely pointing arrows" showing the network connection icon, to the side of volume controller. How to bring it back? It suddenly disappeared on itselfI googled a bit and found that some people told to press alt+f2 and type some command (which i forgot and am not able toremember, sorry!). But that didn't work, although it worked for the person who had the same problem as mine.

I accidentally removed network and sound icon from top panel. Is there any way how to put it back? I've read several howtos that I've to add notification area but it doesn't really work.I know that if I delete this user and create a new one the icons will be there again but I'd like to do it cleaner way.This is how it should look like (untouched user account):And this is what I've done :-/Network icon is missing in both accounts (removed by accident while trying to remove something else :-/ in user "tata" it at least shows sound button.

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.

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.

When I start the tightvncserver (vncserver -geometry 1600x1024 :1) and then connect to it with a vncviewer (tightvnc 1.3.0 on Win7 or vncviewer on 9.10) and then start a terminal (gnome-terminal or xterm) the m key it opens the envelope tab on the panel. The 's' key opens the shutdown applet.This did not happen on 9.10, or earlier

In 11.04 on a Dell Latitude D610 laptop, there are two logins. User1 has sudo privs, User2 does not.When either user logs in, network-manager picks up on whatever remembered wireless network is available, connects, and the nm icon shows in the panel.If the other user logs in (via Switch User), the connection persists, but the nm icon does not show in the panel.
Under 11.04 it appears there is no way to put the nm icon back in the panel, even when the connection is set to "available to all users", and even when the user missing the icon is User1 (who has sudo privs).If control is now switched back to the first user who logged in, the nm icon is still there, and the system is still connected, but if that user logs off (rather than clicking Switch User), the connection is dropped, and when the other user gives their password to resume their session, there is now neither connection nor an icon with which it can be re-established.
This would appear to be a bug, but is there a way to ***FORCE*** the nm icon to appear in the panel? The connection is already set to "available to all users", and doing a networking start does not do anything. Under 11.04 it appears that there is no way to make any icon appear in the panel if it is not already there.

I am running ubuntu 11.04 in classic mode and for some reason the little network icon located in the top panel disappeared. I tried resetting the panels using:
Code:
gconftool --recursive-unset /apps/panel && killall gnome-panel
When I right click and choose add to panel it doesn't show up as one of the options.
I also installed compizconfig and docky then it disappeared. would this have anything to do with this?

With a fresh lucid install on my new dell mini v10 when I'm connected to the internet the wrong icon is displayed on the panel by nm-applet. The no connection icon with the red exclamation mark is displayed when the normal wireless network connection icon should be shown. By the way I'm using the proprietary broadcom drivers for the wireless

I have a weird problem on 10.04 where my nm-applet icon wont show on the panel. Only when there are no known wireless AP around. if there is a previously connected wireless in the area I will see the icon but if I'm at a new place it just won't show up. nm-applet is still running, I tried to kill and restart it but the icon still doesn't show .

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?

Someone on the forums had me uninstall pulseaudio to get pSX working, and now I don't have a volume control icon on the panel and when choosing to add stuff to the panel it isn't available.I re-installed pulseaudio through the package manager, but I have a feeling it didn't install everything that uninstalled with it.

Kwallet is off. Then I install a wireless device under WPA. Wired icon starts to change to wireless icon, but does not and goes back to wired icon. Hovering pointer over wired icon shows wired device installed as well as wireless device. How do I keep the wireless icon in place after installing WPA to wireless device?

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.

When there is a power failure at my university for about 30 minute, my computer stays up because of a UPS, but the switch it is connected to via ethernet is reset. After this, my machine loses network connectivity until I manually select the network using nm-applet.
In System -> Preferences -> Network Connections, the network has the "Connect automatically" box checked.
However, in /etc/NetworkManager/nm-system-settings.conf, there is a line that says:
Code:
no-auto-default=00:30:48:b0:11:07,
and that is the MAC address of the ethernet card.
I'm running Ubuntu jaunty.

I'm a complete beginner who just installed 10.04. I'm trying to follow guides to setup my internet connection, but I am completely unable to locate the Network Manager Icon. I have the notification area already, but there is no icon. I tried the instructions here
After inputting
nm-applet --sm-disable
It gave me:

We have an old Zonet 10/100 switch in our home network that locks up whenever there's a power glitch longer than about a microsecond. (OK. It's not that bad but if the lights flicker, I usually end up going down to the basement to see if the switch is hung.) None of the computers or peripherals are affected by the glitches, BTW. Power-cycle the switch and everything starts working again. After putting up with this for months I finally picked up a Netgear 8-port 10/100/1000 switch to replace the Zonet. Unfortunately, when the Netgear switch is in the network, everything slows to a crawl before completely freezing up. Pinging other systems barely worksname would not work.Pinging another system by its IP address worked a little but packet losses of 70%-80% were the best I saw. At first. Then it gets to where the loss is 100%.
All systems were rebooted after the Netgear switch was inserted into the network. The systems that were capable of gigabit connections autosensed the new switch and set their port speed accordingly. And that's about all that works when the Netgear switch is present. (The Zonet is back in the network now.)One thing I have not tried is forcing the port speed on the gigabit-capable systems to 100Mb and re-inserting the Netgear switch into the network to see if the problem if due to running some of the ports at 1000Mb.The systems on the network are running various versions of Linux (with different kernel versions, of course). Most are due for upgrades to get them current but I was planning on hitting the systems that had gigabit-capable ethernet interfaces thinking that a.) 100Mb speeds have been around forever and no problems have been seen when everything was running at 100Mb in the past and b.) the gigabit support for the older kernels should be better (one system only supports an MTA of 1500 max at 1000Mb).

Our ISP provides us with Layer 2 hardware (Modem?/Switch? (Hatteras)) for our leased line and internet access. I have been told that I should set up a VLAN capable router to separate the internet traffic from the internal traffic. I found that linux is capable of VLAN routing. Nice!
I have setup opensuse 10.3 put in two NICs and did the following
vconfig add eth0 10
vconfig add eth0 20
ifconfig public.ip.add.ress netmask 255.255.255.252 eth0.10 up
ifconfig 192.168.0.1 netmask 255.255.255.0 eth0.20 up
Plugged this NIC into the HATTERAS hardware (with a straight cable), and thought that this way I should be able to ping the public gateway or any ip out on the internet. My ISP is telling me that I should create a VLAN trunk to be able to 'use the internet', but as I understand in linux if I create any number of VLANs on one NIC they are already trunked. I also got the info, that the traffic is tagged, and I can separate the traffic reading the tags. I already read that some NICs are not able to VLAN because they are not able to handle the increased packet size.
Also that the MTU setting is important (dono' the exact value though, only that its important). I thought that a linux machine can act as a router and firewall in such a case, because proprietary switches/routers use linux as embedded os. This is my first meeting with VLAN so if this whole post does not make any sense or you think that I just need to RTFM more then tell me! I also have some (3) Dlink 3226 Layer2 switches around, but I think it would be waste to use a 24 port switch on this subject.

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 was browsing the net very well and without any issues for the past 15 days since I installed FC14. Fantastic experience and then suddenly yesterday after nearly 2 hours of a smooth online session I lost internet connectiivity.At that point I noticed that the network icon on top was showing a red cross. After clicking on it I could NOT eth0. I specifically remember seeing it there before.I checked the cables and the setting to no avail and just could not get it back. Any idea what I should be doing to see eth0 in the connection?Also FYI I have been noticing this from day one since I installed FC14----When going through administration-->network-->One cannot see the red and GREEN activate button that I am used to seeing in FC9. In fc14 its greyed out. So I actually had to go and enter the /etc/init.d/network start command to change the status from inactivate to activate.Also the network manager does not seem to be managing eth01 as it does not appear as an entry in its console.
