Ubuntu Networking :: Nm-applet Disappeared After Using Pppoeconf?

Mar 25, 2011

i have some trouble connecting to the wireless of the dormitery where i live in. so that is what i already did: connecting to the hidden wireless network via nm-applet i typed in my personal user data using "sudo pppoeconf" connecting to the internet using "pon dsl-provider"

so after i did that everything was working out very well and i was able to use the internet without a problem! but after i restarted the computer the nm-applet was gone so i can't connect to the hidden wireless network anymore. if i try to start nm-applet manually the terminal says:

Code:
jonas@jonas-K50AD:~$ nm-applet
An instance of nm-applet is already running.
(nm-applet:1962): WARNING **: <WARN> constructor(): Couldn't initialize the D-Bus manager.
jonas@jonas-K50AD:~$
if i end nm-applet using the system monitor and try to restart it again i get the following output:
Code:
jonas@jonas-K50AD:~$ nm-applet

Ubuntu Networking :: Network Manager Applet Disappeared - How To Get It Back

Jul 1, 2010

The network manager applet has disappeared from my top panel so now I cannot see what local wireless networks are available. I just came from the library and was unable to connect to their wi-fi because the computer wasn't trying to detect it. All I have is a network connections applet that seems fairly useless as it just gives me info on networks I've used in the past and not on any currently available networks.How do I get this Network Manager back and functioning?

Ubuntu Networking :: UNR Network Manager Applet Disappeared / Get It Back?

Aug 21, 2010

Yesterday while trying (unsuccessfully) to get a new Bluetooth dongle set up I lost the network manager applet. When I rebooted, after giving up on Bluetooth in Ubuntu, I had no way of connecting to my wireless network. In command line (iwconfig & iwlist scan) I was able to see the wireless router. So the wireless card is working correctly. How do I reinstall the network manager applet? Oh even when use a wired connection to the router there is no connection.

Ubuntu Networking :: Wireless Disappeared From Applet X220 + Realtek Wifi?

Jul 29, 2011

I am having issues with wifi on my Lenovo X220. What has occurred is that the network applet in the notification bar no longer shows me any wireless network options. When I click on the applet, the drop down shows me: Wired network: disconnected (greyed out), VPN connections, Enable networking (checked), Connection information (greyed out), and Edit connections. Missing is Wireless connections. This occurred "out of the blue" in the middle of using the computer (i.e. NOT just after a reboot or new driver installation, etc.)

I have noted that:

1. Wired ethernet works just fine.

2. Wireless (wifi) works when I boot into Windows 7 or into a fresh Ubuntu USB Start up disk (implying that this is a software issue, not hardware).

3. The hardware led for wifi is OFF (whereas the Bluetooth light is on.) In Windows or using a fresh ubuntu from USB, this light turns on normally.

This may be irrelevant, but the issue started yesterday when I noticed that the trackpoint scrolling that I had enabled using gpointing-device-settings was not working. I ran that app and checked the settings, which were normal. I then reset the computer, and found the trackpoint was working just fine, but I had no wifi. A few resets later, the problem was not solved.

Ubuntu Networking :: Network Manager Applet - Disappeared From Right Hand Upper Corner

Oct 16, 2010

I have assigned ip address to laptop by editing /etc/network.interfaces. From next reboot the Network Manager Applet which was present on right hand upper corner, disappeared. I wonder why? This has happened with 9.04, 9.10 and now in 10.04. Another question is, are Network Manager settings (ip) and /etc/network/interfaces do correspond to same thing or not? As I have narrated above, since network manager applet is no more visible how to see the physical network cable connectivity status (as we do in windows xp)? (is there any other app of such kind or what?)

Fedora :: NetworkManager Applet Disappeared In F13?

Jul 26, 2010

I just upgraded (as a fresh install) to Fedora 13. In so doing I kept the old /home partition. My NetwokrManager Applet is missing from the top bar. But if I login instead as a different user, then it is there. When I did the install, I had to create a (new) user as part of the process. The old passwd file had two users, one called admin, and the other myself. I logged in initially as the new user, and created the admin user keeping the same home directory, user ID and group ID. I then logged out, logged in again as admin, and removed the new user. I then added myself as a user keeping the same home directory, and user and group IDs.. For some reason admin has the applet but I don't. I also don't see how to add it except as a custom laucher using nm-applet, and that didn't seem to work.

Ubuntu Networking :: 10.04 - Eth0 Not Up After Pppoeconf

Jun 15, 2010

I recently installed Lucid 10.04 on a P-IV desktop. The install went extremely smooth and Ubuntu was up and running. Hats off to the Ubuntu folks for the excellent user-friendly experience in the installation process. However , I have run into a networking issue. I connected my PC to the router issued by my ISP. This is a plug-n-play type of connection where the username/password settings are stored in the router and there is no configuration required in Ubuntu for accessing the internet. All I need to do is connect the router and my PC using the LAN cable. I was able to surf the net without any issues.

A few days later , this ISP service was down and hence I switched to another wired ISP. This ISP required me to dial a connection using another supplied router. I setup the connection using pppoeconf where I was asked to enter username/password. Again I was able to surf the internet without any issues. Next , I shutdown the system and before booting it , I switch back to my original ISP connection (the plug-n-play one). But now I am not able to connect to the internet. The router lights show that my PC is connected to it , but when I issue ping 192.168.1.1 to check connectivity with the router configuration, I get

Code:
$ ping 192.168.1.1
connect : Network is unreachable.
Also , issuing ifconfig does not show eth0.
NM-applet also does not appear in my notification panel at the top.
How I can go back to using my original plug-n-play ISP connection? I have read some posts about networking issues , but none quite like this one. Please note that all my Internet connections are Wired connections.

Here is my interfaces file
Code:
$ cat /etc/network/interfaces
auto lo
iface lo inet loopback
iface dsl-provider inet ppp
pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf
provider dsl-provider
auto eth0
iface eth0 inet manual

Ubuntu Multimedia :: Sound Applet Disappeared And Cannot Change System Volume?

Feb 11, 2011

Recently I installed JACK and Ardour to try out. Later I decided against it and so I uninstalled them. After restarting my computer, I noticed that the sound applet has disappeared from the panel, although the battery and mail icons are still present. There is still sound coming out of my laptop speakers, but it is stuck at whatever volume I had it set on before the last time I shut down. Volume sliders inside Banshee and suchll function, but I cannot change the overall system volume, and my keyboard shortcuts for this have stopped working as well. When I go into System->Preferences->Sound, all I get is a message that says "Waiting for sound system to respond." and nothing happens. I've tried searching around for a solution, but nobody I could find seems to have had aimilar problem, and none of the various other solutions proposed have worked for me. I'm on Ubuntu 10.10 by the way.

Ubuntu Networking :: Wired Connection Works But Only By Pppoeconf

Jan 3, 2010

It's been a while since i've been trying to deal with this problem but it was useless. I've found many related problems to this, most unsolved and those who had solution wouldn't work for me. I have few mates who have the same problem and still didn't find a solution as well. Here's the problem:

Both on my Desktop and Laptop, the network manager won't recognize that there is a cable pluged on the computer so that it would start my connection. The solution to make it work is pretty simple and its everywhere: use pppoeconf.

Altough that does the trick to make my internet work, i get another problem that i found out to be related to this one, which is: I can't use VPN. Which make me assume that one problem is related to the other, is that on my laptop, which has wireless internet, ubuntu will recognize it and then i can simple use vpn. My desktop, on the other hand, isn't that lucky and does not have wireless, so i can't just use vpn. So far, i've been using vpn on windows when needed, but switching systems is really a pain, not to say i'd rather do that on ubuntu.

Few other suggested solutions were to use 'wicd' and other network managers, altough for some people that did work accoding to what i saw on boards, that didn't really work out for me as well. Wicd coldn't recognize it either. Other suggestion was to check on some txt file on ubuntu, erase few information and let it 'fill up' automatic, it didn't work as well(sorry i don't remember all details on this one).

This problem happened on:
First, wubi for ubuntu 9.04
Ubuntu 9.04(normal install.)
Ubuntu 9.10
Happened both on my Desktop and my notebook, but the same version i installed on both of them were used on other computers and they did work on them so i strongly believe it has to do with the os itself.

Ubuntu Networking :: IBurst Modem Driver & 10.04 LTS LL Pppoeconf Required After Reboot?

Nov 9, 2010

I'm a Linux noob an I am really desperate for some top, top, top assistance. Been battling a while now with my iBurst USB modem driver and hope there is someone out there that can help? I have been through umpteen forums and threads and tried literally everything I read, but to no avail. I also realize there aren't many Ubuntu users that use the iBurst modem, but I am appealing to the few out there that do.

I have installed the open source ibriver-2.6.31 for my iBurst USB modem. Initially all went well with fast connection etc., connection everytime I boot, until... I started updates of 10.04 LTS, that is when I became aware, from the forums, that a re-install of the driver is required after every package update due to no "package management" in the iBdriver. what a pain in the proverbial to say the least!

Anyways.. now I am the stage where the driver is always installed, but...all of a sudden, I need to run pppoeconf and set up the driver after each boot to get connected!!!! If I can't find a solution it will force me back to Windoze7 which I dread to do! Can a script be written to pppoeconf (rp-pppoeconf.iso is loaded I think) automatically during boot perhaps?

So any top Linux hacker or "notsonoobasIam" user out there with a iBurst modem and similar pains & mis-fortunate experience please share your ideas and thoughts to correct this problem permanently for me please? (I should maybe mention that the other day I performed the "Grub2 Profile" exercise to try and speed up the boot time, this does not perhaps have something to do with the fact that I need to reconfigure in pppoeconf after every boot does it? I doubt it)

Debian :: Router Or Bridge Mode And Pppoeconf?

Sep 24, 2010

I wonder what is your opinion about the best method for using an ADSL modem. Router or bridge? I did read some articles that say "that the bridge mode gives you more stability and has higher speed". Is that true?

Furthermore, you suggest any alternative to "pppoeconf"? I've been getting this errors ( in the plog), related to "PAD packet loss" and also errors in "PPPOE Discovery", even when I am connected. When this things starts to show up on the log, my connection "pauses" for some seconds. I do not feel very safe with this program.

Ubuntu Installation :: Can't Move Indicator Session Applet To The Right Of The System Date/clock Applet

May 6, 2010

I thought I was removing the chat status piece of the indicator applet (I know what it is now, didn't then), but I accidentally removed the whole thing. Now when I figured out how to put it back on the panel, I can't get it back to where it was (which was to the RIGHT of the system date/time applet). How can I do this as well as move the indicator applet that has the volume control in it?

Ubuntu :: Conflict Between Indicator Applet And Notification Area Applet?

May 15, 2011

I was using both the Indicator Applet and the Notification Area applets in my panel but realized that very often when I started the system, the icons of these applet appeared mixed. Some items were duplicated (for example the keyboard indicator) where others were missing (sometimes the battery indicator, sometimes the sound indicator, etc). When that happened I had to remove them and add them to panel again.

This seems to be a bug that makes one applet interfere with the other (maybe because there are some items that appear in both but when you add both initially nothing is duplicated but after a system restart the problem happens).After searching for some way to fix this apparent bug without success I decided to remove the Indicator applet and keep just the Notification Area.

It works but then I don't have the sound applet anymore, because it was part of the Indicator Applet.
I searched for a standalone sound applet but I couldn't find any. Do you know of any such applet that I could install in the system? If I can find any it would be fine to me and I would be satisfied using just the Notification Area.
