Ubuntu Networking :: Network Manager Will Not Auto-connect To New Network After Resume?
Jul 1, 2010
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.
If I made a distro from scratch it would have been Lubuntu, cept I'm sure my theming would have been horrible. Now Ive installed on a couple of my Laptops, and even had a few friends convert, and for the most part everything is hunkus doris, cept one small issue thats keeping me from slapping it on my trusty laptop. I'm lost as to what the problem could be. Ive tried just about all I can think of, but I use sprint mobile broadband to connect to the net and then use Network Manager to share this connection with the laptops and Palmtops around the house. I can get my sprint modem to connect thats not a big problem the problem is now I cannot get the Auto Eth0 to connect to send out as a share. It just refuses to connect. Now this is not a Lubuntu problem at all Im sure its somehow a Lxde problem, as Mint Lxde, PeppermintOS, and so on do the same thing, refusing to connect Auto Eth0 while Sprint is connected. Any Gnome based distro this works flawless, as does Xfce distros, so Im sure this is somehow something within Lxde. Im sure its down to just "missing" a file or some stupid overlooked thing.
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 am running openVPN to secure my wireless network traffic right now. Everything works great except every once in a while, my Internet connection will drop out for about a minute or so. Ubuntu very nicely tries to reconnect, and most of the time successfully does. The issue is that if I don't catch it every time this happens, I am now running without my VPN.
I want to know if there is any way to DISABLE auto-reconnect to a wireless network if connection is lost or signal fades.
I got a little problem with network manager. I got two connections in it, with two different DNS-Servers, because the one of my provider is very slow I surf with opendns, but sometimes that slows down too, so I want to change if necessary. Both connections got the same fixed IP.That worked all fine, until I got my new router (it's a Netgear WGU 624). It's connected by cable and I configured it like the old one. But for some reason instead of connecting to the manually configured connections, my fedora 10 creates a new one "auto eth 0" with a dynamic IP. So every time I boot or switch on from standby my PC connects with this one and I have to manually set it to the right connection. There's no chance to edit or delete it cause those two buttons are grey and won't work. I also tried restarting network manager manually and I also tried starting it with su as root.
I'm running Kubuntu 10.4. My problem is that Network Manager keeps defaulting back to Auto eth0. I have created a new wired connection and set my manual addresses. I have ticked the 'connect automatically' button. Every time I reboot or wake up it reverts back to Auto eth0.I did have wicd installed but this was not reconnecting after wake up (said it was connected but I couldn't ping etc), this is a pain also.
Upgraded To Ubuntu 10.04 The Other Day. And when I first installed it everything worked great except for my sound card which I fixed. But there was no problem with connecting to my Router via an Ethernet cable. Then I updated the video card drivers, restarted my PC and it wouldn't connect. It would try over around 1-2 mins then tell me its disconnected. No green light activity on the router / network card either.
I've reinstalled fresh copies of Ubuntu a couple of times now, Hoping to get the default settings back. But nothing has worked since.
I looked around the net and found quite a few people had this problem on previous versions of Ubuntu but it would seem most of there fixes were for there Version, so it hasn't helped me.
Heres some info:
I've tried all the various things from dhclient to ifup/ifdown etc etc.
I've been trying to get and old PCI wireless card to work on Ubuntu 10.04. The card is a Zonet 1602. It was not recognized automatically.
I have been able to get it to work using ndiswrapper except that when the computer is started it does not automatically connect to the network. I can click on the network icon and select my network from a list and it will connect, including properly authenticating the network key.
I have worked through a lot of information on the web but much of it seems to apply to earlier versions of Ubuntu and some if it does not match what I'm seeing in 10.04.
There is a built in Ethernet controller on the mother board but I have disabled it in the BIOS.
I have a Broadcom 4312 wireless chip. I have use the STA drivers that Ubuntu recommends. I can connect quite easily just by clicking on the icon, so this is more than a niggle than a problem.
My network isn't protected as we live in the middle of nowhere (quite literally) and network theft isn't a problem. We also run a self-catering cottage, and let guests have free access to our network anyway, so it is easier for guests to access our network without me having to give them all the key. When I did use wpa, it would start itself up with the laptop, so I kind of know that this might be the cause. Is there any way I can fix it without encrypting the network?
Yhe only ptoblem was that he had forgotten the password to his network. This was really anoying and has happened before sp yesterday i decided to install some kind of WEP cracking tool so that it would not happen anymore.. After using sometime without getting anything to work i found this tutorial: [URL]
and started following it. i only got to the point where he has updated his computer using update manager and is about to patch his wificard. Then i noticed that the network manager for gnome was gone and the virtualbox logo in my top panel was changed to a red circle with a line running through it. I have tried to download network manager from another computer and installing it on my laptop but it needs internet to install. Then i tried to connect to my local network using terminal that did't work either i also tried connecting using a cable but had no luck connecting. The command iwconfig gives me:
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.
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.
All settings are correct as far as i can tell. The wep key works on all my windows boxes. When i have connect automatically enabled it never tries to connect. if I go to edit it it pops kde wallet up i put in credentials. wallet goes away then nothing happens. if i double click connection to my router also nothing happens. I have the wep key in there and i even made it visible to make sure.
the thing is that I cant use Network Manager to connect to Internet, because it simply do not connect. The connection, although, awailable throught yast when i choose "traditional method with ifup", so everything is just fine, but if i need to reconnect, i have to reboot. How do I setup a !working! connection through Network Manager, or maybe i do not do something properly.
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 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'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 am a Windows refugee who discovered Ubuntu as a way to save my files from my virus-ravaged computer. Had no installation discs for Windows, so when I had to wipe my hard drive and start over, I decided to give Ubuntu a try. I've had mixed success, but that's another post...
Right now, the problem is that I installed 10.10 two weeks ago and was able to connect to the Internet with no problems - until yesterday. Suddenly, our wireless network (the only one in the vicinity) does not come up as available in Network Manager. In fact, the entire wireless option disappeared. I know there are many posts and threads on here about this, but weeding through them trying to find an answer is more frustrating than actually dealing with the problem. I know the router works because I can post on this forum from the Macbook. I really like Ubuntu and would like to keep using it, but not being able to connect to the Internet now on top of the other issues I've had is making me doubt I want to continue down this Linux road.
P.S. When I attempted an analysis through System Testing, it said something about there being no proprietary drivers?
