Ubuntu Networking :: Network Manager Applet Never Displays Connection?
Oct 9, 2010
I'm running lucid 10.04 on my netbook (regular desktop distro though). I enabled the proprietary drivers needed to get wireless working (I have an hp mini 110 by the way), but the applet in the taskbar will never show a connection, even if it is connected.
I use network manager applet 0.7.1. I had set the automatic wireless connection to my my wireless network (WPA key secured). Recently, I get the following problem: At the automatic connection, I get the message: Network manager applet (/usr/bin/mn-applet) needs default keyering. As I don't know what it is to type it and then, deny or OK, it doesn't get connected to my wireless network.
At first I use to have a Network manager applet for my wireless connection in the panel. But somehow it has gone missing from the panel. I am quite puzzle as to how it happen. So I just need to get it back so that I know whether or not it has been connected to my wireless router.
I recently acquired an HP2133 netbook. It comes with SUSE 10 enterprise desktop pre-installed. WI-FI was working fine, though a slight pain for asking for the key every time. I thought I would apply all updates I could find and that may improve my networking.Having applied all I can find the wi-fi is now broken.If I use YaST I can see the Broadcom internal device seems to remain recognised, it even has the configuration I set for my wi-fi network access.The problem seems to be the NetManager applet, which denies all knowledge of wi-fi now and only has wired (which is working).Ironically the update causing the failure was applied wirelessly.I am slightly at a loss how best to proceed - I was going to cut my losses and make another boot partition with Ubuntu, but the live CD I made failed to run so that I could make a flash boot version, I shall have to return to that.
I have also now discovered that SUSE 10 is a bit long in the tooth - I sort of assumed it was current, given I bought the machine recently. So I'm wondering if it would be best to take the hit and reformat completely? I know it is broadcom, so should not be a problem, and I have been through ndiswrapper and the like in the past, though somehow I seem to have forgotten all about it now!I was happy enough with the SUSE setup and this is highly annoying as I was only updating to fix an annoyance and now the wifi has been broken... Perhaps there is an alternative applet to the netmanager that may play with the card and allow me to connect to networks?I look forward to recommendations, at this time my primary objective is to restore wifi functionality, longer term perhaps I need to review distro and installation, but I should like to do that on a dual boot basis I think
Whenever I start up my laptop i do not get a wireless connection automatically. I have to rightclick network manager applet and select enable networking. After that everything works fine untill i shutdown and restart my laptop. I would like a way to change this so that my wifi connection is working whithout having to click something first..
I'm not sure if I have two seperate issues or one inter-related issue. The Network Manager applet wasn't appearing in the tray, found out it wasn't installed. Installed, still didn't appear. Tried installing WiCd, WiCd did appear but couldn't find any networks. I had installed restricted drivers previous, decided it was worth another look. Found that Broadcom STA Wireless Driver wasn't installed. Tried to install, it said it couldn't and said I should review the var/log/jockey which is....excessively long.
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?
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.
I lost my network manager applet after removing kde-desktop. restore it, as I dont find it in add to panel applications I dont have any clue, also how could I add bluetooth applet in notification area.
I cant use the option "export" from the VPN settings in the Gnome Network Manager, when I tried to export a popup says "Unknown error"This happend also in 11.3 and now in 11.4, so it is a nm-applet problema I think... Is there any other way to export my VPN connections?
On about 90% of bootups I find that network manager has disappeared from the notification area to be replaced by a random duplicate of one of the other icons (at random). If I remove the notification area and add it again all is fine.
Accidentally I removed the NM Applet from the panel and I am trying to reset it. When I right-click on the panel and "Add to Panel", I couldn't see Network Manager. Hence I couldn't connect to the available wireless network. I am able to add Network Monitor, which is similar to Network manager, but this just displays info about current network.
I seem to have a little problem with the Network Manager applet - it works vaguely OK, even if it takes a bit long to find my connection, but when I click on the icon, the menu doesn't show.I have also installed the applet through the Ubuntu Software Centre.Just to clarify, the icon appears fine in my panel, and the notifications appear when I am connected, it's just that the menu doesn't appear at all.
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?)
I have just started using fedora 13 and I am not sure if i am in the right area but here goes...today I was online in my fedora 13 partition on my laptop and I had been online for quite a while then I shut down my machine to recharge the battery then a couple hours later I turned it back on and all of a sudden my network manager applet was missing and I could not connect to the internet, I opened firefox and tried to get to my homepage but it basically just told me that I wasnt connected..
I suspected at first for some strange reason that MAYBE it was my NIC so I booted up into my vista partition and low and behold the internet works fine, so the problem is on the linux side, I have tried every command nm-applet but it just keeps saying an instance of nm-applet is already running, I have no clue how to restore the network manager and get my internet back and the only other piece of information I have is that earlier today I did do a bunch of security updates but the internet was working fine all day even after several reboots through out the day.
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 question regarding the configuration of Network Connection. My wired connection is fine right now and when I check the network connection applet, it display active information of eth0. However, when I click the Configure button, the Network Connection window appears but there's nothing in the Wired panel. Should there be a eth0 in that panel? I remember I had one before, but after I messed with some configuration of VPN, my network became unstable and I remove the Network Manager to try to solve the problem. Since then, there's nothing in my Network Connection window, though I can still connect to my router with eth0. Now even after I reinstalled the Network Manager, I still don't get anything.
Seems like i have an issue, and the applet vanished even though after some attemps typing to reintate it with: ALT F2. nm-applet I was advised to insert the gui panel but seems i do not have on version 10.04
After connecting my phone via bluetooth using Blueman and then activating Dialup connection in Blueman, it says "Now DUN is available in Network Manager" or something like this. But, there is NOTHING about DUN connection in NM. What this thing is telling about?
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.
I just wanted to know what's your opinion on my problem.I have few linux servers that can be located on any place in the world, only port 22 is open. At my office I need connection to every server, but every server must be isolated from every server.So by now I worked only with ssh authorization by username and password. What seems to be preferable ?.
1 Going on working with ssh with authorization. 2 working with ssh but with adding keys 3 start to work with vpn
So if I am keeping use ssh with authorization I need something that will change password every month only for security working with ssh key, it seems like key depends on gateway where key created so if change gateway I lost connection using vpn sounds good but in this case I mush isolate servers from each other.The best solution I think is combination of any two methods
how to change the IP range provided by default by Network Manager / dnsmasq from 10.42.43.-- to something else?
I have setup a working network using a Bell wireless modem (Canada) and Network Manager in 8.10, 9.04, and 9.10.to do Internet connection sharing. In 8.10 the only way I could get it to work was with WICD and KPPP, many hours spent on this one. I got it to work in 9.04 and 9.10 using network manager, but certainly not out-of-the-box. If someone would like some tips on how I did it, in each case, let me know.
My current challenge is trying to set the dhcp range of dnsmasq (which I am 99% sure is what is handing out addresses) from th 10.42.43.-- address range to a 192.168.0.-- range.
I HAVE edited /etc/dnsmasq.conf and can get the edits to this file to break the setup (dnsmasq will not start) but have not been able to get it to change the IP address range.
It seems that either this file is ignored, or overridden by some other process. I have looked at the very good post at [URL] about dnsmasq but this does not do the trick.
By the way, the way I can get this to work is to start NM, establish my cellular internet connection, then kill dnsmasq then establish my ICS network (on eth0). If I don't kill dnsmasq, then it does bring up the connection, but it then shuts down in a matter of seconds. It is all very manageable using a launcher (kdesudo pkill dnsmasq) on the task bar, but not all that elegant.
the IP range and where this is provided to Network Manager or the network itself is my real question now.
- a wired network - a wireless network - a mobile broadband network as both "system connection" and "automatic connection".
I need to have a laptop that will try to connect as sson as I plug the ethernet cable in or as soon as it senses a certain SSID or as soon as there's a mobile broadband device plugged into a USB port. Non-system connections are working but I am not willing the actual user (non-admin) to read the WPA2 key or the SIM PIN. But the check box for the system connection is disabled. And running "sudo kcmshell4 --icon networkmanager kcm_networkmanagement kcm_networkmanagement_tray" doesn't result in a system connection.
I've read a lot on the internet about various ways of doing this but i've been unsuccessful each time. Basically what i've done is accidently un-installed network-manager because I was having trouble staying connected on my WPA network. The easiest way of reinstalling it I know of is using the CD but I don't have a CD ROM drive and the pen drive I used to install it I no longer have.
I tried using a program called Keryx but you need python installed and from some reason this doesn't come with ubuntu 10.10. I've also downloaded the .deb packages but I still need to download 200kb which is a killer. I've also downloaded it from here too [URL] but the install file makes no sense to me as i'm not a massive linux user. One last thing reinstalling isn't really an option as i've already put a lot of time into setting up this computer.
I'm trying to share internet connection with my wifi capable mobile device. For that I'm creating ad-hoc wifi connection in networkmanager with 'shared to other computers' ipv4 option. And there is the problem - the device cannot get the setting via DHCP. The firewall is adjusted properly by NM, dnsmasq is started. I've looked at dnsmasq arguments string and found that the temporary config file which is provided by NM is empty. So, where else should I look for a possible reason or should I just post a NM bug?
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.
I'd like to use NetworkManager on a freshly installed CenntOS 5 on laptop Lenovo ThinkPad T61p. I followed: [URL] Everything went OK, until I selected my active LAN connection in "Edit Connections". After clicking on "Edit", it's not possible to change anything - all is grayed-out. I'm guessing it's a permission problem. But I don't know the internal structure of NetworkManager and what files to look at. I was also expecting that after stopping the network service "Syetem->Admin->Network" would be inactive, but it isn't. Shouldn't the old network manager be uninstalled as well?
