Ubuntu Networking :: Network Manager (Disconnected) Cannot Connect To VPN
Mar 20, 2010
I'm running Ubuntu Karmic Server with Xfce desktop, the problem is the network manager, it says it is disconnected, even though I am connected to my network and getting an internet connection. It wouldn't normally bother me, but I'm trying to setup a VPN using the network-manager-openvpn plugin. I put in the required details for the VPN connection, but as soon as I tick the "apply to all users" box, the information is lost. The information will remain if I don't tick that box, but it will not connect. when I try to select the VPN connection I just setup, nothing happens.
I've tried the exact same configuration on another desktop, running Ubuntu Karmic with Gnome desktop, the network manager works fine, my ethernet connection is showing as connected, and I can connect to the VPN no problem, the problem lies with the network manager in Xfce. Is there anyway I can get it to show as connected? it wont allow me to connect to the VPN otherwise, it's silly, because that adapter has a full working network connection.
Look Buddies,an interesting issue. Once i just remove X11 libraries , gdm , gnome libraries and network-manager applet. from the ubuntu 9.10. after these uninstallations, i used my internet successfully through text interface browsers which is links
but i understood graphical interface are important for my work. Once again i installed 1. xfce4 2. network-manager applet
Everything Graphics,X11 sessions and accessing internet is working fine. i can even browse through Mozilla firefox. But my Network-Manager applet is always show as disconnected in taskbar. I understood some kind of understanding between network -configuration files and network-manager applet are broken Why is the Network-Manager Applet is not responding?
I recently fixed an annoying problem and I thought it would be nice to share my solution here. The problem was that after a cycle of suspend/resume, Network Manager would only auto-connect to the same network as it was previously connected to. So, for example, if I suspended my laptop at home, and then I went to school and resumed it, it would try to connect to the home network, and then just give up. It would not connect to the school network unless I explicitly told it to.irst, I'll describe the fix. If you're having this problem, you can this. Copy the following:
I have used ubuntu in the past but had a lot of hardware issues with it and unfortunately moved back to windows (( BUT i have tried Ubuntu again and all seems to work great except wifi My wifi connection is sort of working because when i run SUDO IWLIST SCAN it does pull up all available networks. But in the network manager icon on the panel i left click but i see no networks and can't connect to anything. I WOULD LOVE TO keep Ubuntu and use it permanently but I must get wifi working or else this won't be possible.
I recently put Linux on a Thinkpad T40 I got. The wireless card works out of the box--I can see nearby networks. However, I can't connect to mine. network-manager would try (spin spin spin), fail, ask for the password, and then go back to the beginning and repeat indefinitely. This happened to me on a different computer, and on that one all I had to do was use wicd instead of network-manager. So I installed wicd, but it's not working either--it hangs at "Obtaining IP address".
I've found many, many threads with people who had the same problem, but none of their fixed worked for me.
I also tried to get wifi going manually, using this guide, but that didn't work.
I'm trying to use wicd instead of network manager because I want a "no fuss" way to use wireless on wmii. However, wicd will not find any networks unless network-manager has been run and has connected to a network since startup. If it hasn't connected to a wireless network, the wicd will find no networks, and iwlist won't provide a list of networks either.
This seems to mean that network-manager is doing something to the interface when it connects that needs to be done to make it usable, but I'm not sure what it is or how exactly to find out. I do know that the interface (eth2) will not appear in ifconfig if network manager hasn't connected, which I assume means that it hasn't been brought up. ifconfig eth2 up makes it show up, but I still can't connect with wicd. What can I do?
I'm running Ubuntu 10.04, generic 2.6.32-22 kernel, MacBook 5,5 using the Broadcom STA driver. (more details below)
i was fed up after i can't connect to wifi using ubuntu. the problem happened after my router is being replaced to a new one because the old one got struck by lightning. good thing i dual-boot my laptop so i can access the internet using Windows 7 now.
i use the default network manager to connect to wifi before, but it all seem to be failed after the replacement of router. i also used Wicd but it failed to connect either. it says in the notification "disconnected: bad password" but the password was right. my wifi used WEP password with open authentication.
i even remove the WEP password and try to connect, but it failed. all i can do is to boot in windows 7 and surf internet there. what could cause this problem? is it the router, the telephone line? i can set the router settings if i want, but i don't know what causes the problem.
I followed (or at least tried to follow) tutorials on doing this. I installed network-manager-pptp and tried to configure network manager to connect to a VPN. In the settings when I select MPPE with 128-bit encryption, after I've selected it and applied it, I check the settings and it's invariably unchecked. I tried using KVpnc after getting frustrated with network manager, and I can't seem to get that working either. I've been trying to search for info on this, and I can't seem to find anything on why I can't select MPPE with 128-bit encryption. That seems like it might be why I'm unable to connect to the VPN?
I have a problem with network manager. I use Ubuntu 10.04 on a Dell Latitude D530. I used to have the same problem with Ubuntu 9.10 before I upgraded. I typically connect to two wireless networks: HOME and WORK. Both networks are set to automatic connection mode. I am at work, I connect to the network WORK. At the end of the day, I just close the lid and go home. At home, I open the lid and have the following problem: network manager still displays the network WORK whereas it is clearly out-of-range and it automatically tries to connect to it. It does so until network manager asks if the password is correct.
If I want to connect to HOME, I have to tell network manager to do so. Then, I receive a notification that I am disconnected to WORK. Next morning, I go to work, and I have the same problem, network manager tries to automatically connect to HOME. What I would expect from network manager: when I am at home, NM automatically connects to HOME and does not display WORK, when I am at work, NM automatically connects to WORK and does not display HOME.
I have ticked the box Connect Automatically in the OpenVPN setup I configured in the gnome network manager but it doesn't connect on startup. It connects perfectly ok if I manually select the VPN but i'd like it work immediately on launch.
I have autologin on Ubuntu but since there is no VPN password to decrypt I don't see why it should be a problem.
I am trying to connect my Asus EEEPC to an option icon 431 usb modem.
I have successfully installed the HSO driver however am unable to connect through network manager. I have successfully connected through Rhel Beta 2, Fedora 13 and Ubuntu 9+, however, desperrately want to be able to use centos 5..5
I have installed WvDial (apparently) but it has no icon or launcher to start it by default, how do i get it to run? I also need basic set up how to. I am running Ubuntu 9.10 (Karmic) and network manager doesn't seem to be able to use my modem to connect to the internet (set up wizard works, appears connected, but then I get page not found error). Hence I wish to use WvDial to try to connect instead.
This is on Lucid, using a Dell Mini. I installed the required packages for a USB tether to my iPhone. Network Manager recognized it immediately as wwan0, but it doesn't connect. Also, it never asks me for the password to connect to the Personal Hotspot (as it does when I can connect from Windows).
I have a 5720 Mini PCIE broadband modem card and though it works, it won't connect automatically in a Ubuntu system. Network Manager says it is enabled when I right click on the icon, but when I do a left click it says it is disabled. I have to right click and disable and then enable before my Verizon connection will work.
I have updated the system this morning and the vpn stopped working!It gives me an error: invalid secrets.I use network manager to connect to a pptp vpn connection, I use fedora 12.Does anyone know the problem?
I successfully installed openvpn and networkmanager openvpn plugin. Then I successfully added a PPTP vpn connection by networkmanager vpn tab which name is "vpn1". But now I don't know how to connect to this PPTP vpn connection. I tried bellow command but no luck. openvpn --config vpn1.config
I have been an Ubuntu user for a year or so. My level is still ultra n00b but I am trying. Whenever I update Ubuntu there is always a WiFi problem, always. So now I am having problems getting wifi to work in 10.10. In Network Manager I can view wifi networks fine but I cannot connect. I tried with wicd also but I got as far as "getting ip" and then it would hang up.

I am not sure what driver I am using as I don't know how to exactly ID my driver. I know there is a way to ID the driver using airodump-ng but I have yet to find it. I have a feeling this is a driver issue as one time I was able to establish a connection that then dropped a few minutes later. I have a feeling I should be disabling/removing the current driver and replacing it with ipw3945 or possibly a driver ndiswrapped? The problem is I cannot figure out how to remove the current driver.
I was going to switch back to 9.04 but I thought I would try to manually figure this one out instead of taking the easy way.
I tuned on my netbook and my wireless signal had a red exclamation. Wireless is enabled. Wireless Networks shows disconnected
I don't get it. Can't seem to get it to connect? How? If I open the connection information I can see the wifi networks around me. And edit/add/delete. But when I go back to the signal and click. it just shows wireless network disconnected and no option to connect. What to do? I have restarted the computer, router, cable modem, etc. Done the updates.
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.
I recently updated my ubuntu to the newest version 10. I have a DSL router with a password. When I try to connect to the net it will try to connect for about 5 or so min then say that I am disconnected. I cannot remember what option I had before to connect but its not on this version.
I'm using ubuntu karmic and I'm not able to connect to the internet with my reliance netconnect data card using network manager. Other distros like fedora, opensuse n sabayon connected easily with nm. Ubuntu detects the data card flawlessly but just doesnt connect.This problem has been persistent even in previous ubuntu versions, n I used to use wvdial. But downloading wvdial on some other comp with every dependency is really cumbersome.
I currently have a Nexxt Lynx 150 Wireless USB adapter attatched to one of my home destops to recieve my wifi signal, however, i have run into a speed bump in terms of getting it connected to my ubuntu 11.04. This adapter works perfectly in windows and on the ubuntu live cd, but, when i install ubuntu to my hard drive and try to connect to my network,
it just takes a very long time, then says, disconnected. My signal is WPA2-Personal protected. Here is a link to the adapter's home page > [URL] It seems to me that this is a driver problem. The cd that my adapter came with has drivers for linux on it, but i havent the slightest clue how to use them.
I've FC10 installed. After updating a few days back, I'm unable to use Network Manager to connect to the net through my USB Modem. All the threads I've read say to do
Code: yum update NetworkManager but how can I do it without net connection? Can anyone post the exact link of the Network Manager's latest and BUG-FREE rpm so that I can directly run it?
Everything worked fine until I downloaded some Ubuntu upgrades. Now, every time I try to connect to internet via network manager it says: " Network: Disconnected - you are now offline". so what to do...
The title message appears when I log in. Neither wired nor wireless network adapters show in ifconfig output. Network manager shows a simple networking disabled greyed out message. Both adapters work in live cd boot. Everything was working properly before; I'm not sure what happened.
I'm having network problems and I have no idea how to fix it. At first, my internet connection was suffering on all computers on my network (Mac, Windows and Ubuntu 11,04). So, I disconnected my cable-modem and then reconnected. Nothing.... So, I rebooted my Windows machine and the internet came back on that computer.
I then went to my Ubuntu computer and clicked on "auto eth0" (per the way I interpreted instructions from the internet). The symbol turned from the "two arrows" to what looks like a wireless, looking for a signal. I thought that maybe I should just reboot, as I did with Windows. However, when I did reboot, that same wireless symbol was there, then a message came up saying:
Code: Wired Network: You are now disconnected I can't seem to get my internet connection back on my Ubuntu computer, though it is working on every other computer on my network.
Ive installed 10.04 on my laptop and notebook. It works perfectly on laptop. On notebook the problem is it finds no Wireless network and just says disconnected. I have no idea how to connect it, I tried reinstalling Ubuntu but no luck. I tried looking it up on internet but no luck in finding help. its an MSI U130. The wireless is defently turned on.
I installed xubunto 10.4 on my pc the other day and every thing was working fine and then the next day my wired network card went down. So I restarted it and it say Wired Network Disconnected. I tried doing sudo ifconfig eht0 up to try and bring the card back online but nothing happens. I also tried reinstalling xubuntu on my computer. Again my internet works then starts freezing up so I restart it and my ethernet card goes down again. I have tried also plugging it into the second ether net port on my computer but that does not seem to work. Also I went into my dhclient-script and went to the bottom to look at my network card stuff.
It reads #Changed from 'ifconfig $interface inet 0 down' - see Debian bug #144666 ifconfig $interface inet 0 exit_with_hooks 2 "$@" fi
i used to download files using transmission bit torrent client. I download the torrent and once the download starts i will leave the system and check only after 4 or 5 hours later.But when i check the system again, the network connections were automatically disconnected.The download is getting stopped naturally. why my wired network connection is getting disconnected automatically if the system is idle?(ubuntu 10.10)
I have successfully installed xubuntu on my 2nd partition of hard disk through unetbootin. everything works fine except wireless network. my ethernet works good, i am tethering through my android mobile no problem....just wireless says disconnected where as it is enabled. As far I know its sould scan all the available wireless AP near me and it should appear below wireless networks, and from there I should be able to select the AP which I want to connct...
