Networking :: Ubuntu Freezing When Network Manager Is Started.(11.04) / Fix It?
Jul 25, 2011
Yesterday I had to use my netbooks Acer restore program to restore my win7 partition to factory settings. This morning when booting up unbuntu, I was greeted with the guild freezing every time. I also booted in classic and had the same problem. I decided to open safe mode and deactivate each program one at a time. WHen I get to network manager Unity boots fine. I then try to start Network Manager from inside of Unity after it boots and as soon as it boots, the entire computer freezes again, it was booting fine until I had to restore my win7 partition, win7 networks still work. It's and Asus Aspire One 722.
Adapter: Ralink RT3090 802.11b/g/n Wi-Fi Basically, whenever I disable it, I can't get it to turn back on. If I hit Enable, it says device is not ready. What can I do to make it work ?
My screen has started freezing periodically. The mouse still moves the cursor but nothing else responds. Ctrl-Alt -F1 doesn't give me a terminal screen nor does Ctrl-Alt-Backspace restart X I must turn off the computer and turn it on again to reboot. I don't remember having this problem with Fedora 11, but I recently moved to Fedora 12. I am using the kernel
2.6.32.14-127.fc12.i686.PAE Looking at /var/log/messages, I find repeated instances of the error message [drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(4). before the reboot.
Google provides many references going back to April for this string, mostly on Ubuntu related sites. I do have an 128 MB ATI Radeon X300 graphics card but it is over four years old, and I didn't have this problem with earlier versions of Fedora. Also, the google references seem to refer to hibernation, which I am not doing, at least not intentionally. Finally, I see that Xorg configuration has changed significantly since I last checked. (I can't find xorg.conf.) Can anyone refer me to a relatively succinct description of how it now works?
What's even weirder is it unlocks when I press power on my desktop. When it freezes, I have several windows opened, and I'm switching between windows. I can still move the mouse, but cant click anywhere. Cant select anything yet there are still cursors flashing (text editor or terminal). The only thing that will unfreeze everything is the signal from pressing power (not rebooting, just quickly pressing power).

I've been using Firefox Portable for ages, mainly between my work (Windows XP) and home (Ubuntu) machine. Recently, just on Ubuntu (10.04), Firefox Portable has started freezing on pages containing Flash. Anyone else experiencing this? I've done a clean re-install of Firefox Portable, then just added Flash, and it still freezes.
My ubuntu system has been running really well until this morning - software update prompt appeared on the screen, so I ran with it and let it do its thing. A while after this, my WiFi network connection started failing. I've tried rebooting and then it can take up to five minutes or more for the password (keychain) prompt to appear. Once I have typed in the password the network connection starts to work. Then cuts out. Works. Then fails again.
I have a HP Pavilion dv4 that is 4 months old. Yesterday it suddenly seemed to restart then once I logged in it turned off. When I tried to turn it on some of the lights came on and the caps lock and num lock started flashing. Since then I have not been able to get it to work correctly.It once seemed to turn on but died again after the login window.I tried to use my live cd but the same thing happened. It started loading once, but then shut down again. Every other time it stayed dead minus the lights
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 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?
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 have the problem with my notebook, that, after I used it at work, the network-manager always tries to autoconnect after boot. He has no cable network and so I get the message "not connected" after a while.how to tell the network-manager, not to autoconnect each time?
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.
My wifi connection drops sometimes and, for some reason, Network Manager attempts to connect to my neighbor's network, which requires a password (which I don't know). Is there any way to blacklist a wireless network so that the Network Manager will never attempt to connect to it?
I had trouble connecting to a wireless network with openSUSE, so I tried the YAST network manager to see if that fixed it. Not only did it not fix it, but now I cannot connect to any network, wired or wireless. I tried to open the default network manager and it said "Network management disabled". How do I re-enable it?I also have set YAST settings back to their originals with no luck.
I'm try to create a mobile broadband connection using my Huawei E 1550 medem. but in Network manager there is not way to select my modem in the first step ( device selection step ) the drop down menu is locked. what to do ? how to configure my modem with ubuntu ?
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..
Neither of my wired network connections are listed in the network manager applet. I know that networking seems to be functional since I can ping local devices on the network. I can't resolve DNS names however. I suppose this is because network manager usually handles DNS? I've posted the outputs of various configurations below.
Code:
/etc/NetworkManager/nm-system-settings.cfg # This file is installed into /etc/NetworkManager, and is loaded by # NetworkManager by default. To override, specify: '--config file' # during NM startup. This can be done by appending to DAEMON_OPTS in
why, every time I started gnome, update-manager show me the error icon?seems like there are errors but if I lunch apt-get update or aptitude update it works great.
Loaded Ubuntu 10.4lucid on TransPort NX Mobile Pentium II, 328MiB,Using Netgear Rangemax wn511b. with Broadcom STA wirless driver. bcm43gx.Boot computer and network manager shos "no network devices available" Run system/administration/hardware drivers and the Broadcom STA driver shows up (only one that shows up) REMOVE and then ACTIVATE and the network manager sees it and connects fine. Shut down computer, restart and no device. I am forced to Remove and Activate each time I start the computer.Is there a way to set this driver to be found and run at computer start.
Since the last update the 'wireless network authentication required' box keeps asking me for my wep key. Everything was working fine previously, I've even re-installed ubuntu just in case it was something I did....again everything was working OK until I installed the latest Nvidia drivers and updated ubuntu.I can see my wireless connection when I click on the network manager icon I just wont connect.Wired connection works fine.
I'm trying to change my network settings under Gnome and 9.10.
System->Preferences->Network Connection brings up "Network Connections". Under the "wired" tab, I see "ifupdown (eth1)". The edit button on the right side is grayed out.
Is this where an IP address can be config'ed, or is it somewhere else?v
I've installed Karmic after using Jaunty for a year. In Jaunty, my wireless Belkin USB adapter would get it's best signal if I set the rate at 11M...sudo iwconfig wlan0 rate 11MTo avoid having to enter that in terminal after a reboot, I followed the advice of Raven on another thread that suggested using WICD instead of Network Manager, as there were options for scripts in WICD that would allow a startup script...sh -c "/sbin/iwconfig wlan0 rate 11M"This doesn't seem to be working for me in Karmic (my connection constantly drops). Plus, the new icons for WICD are distracting (it changes color from green to yellow when the signal goes from good to low) With Network Manager and setting the rate @ 11M via terminal, everything seems rock solid (I left Last FM on last night and it was still playing when I woke up).
I used Ubuntu for the first time yesterday (V.9.04) and imediatly upgrade it to V.9.10. After,the DSL conection failed to conect. After reading many threads here I was able to connect by opening a terminal:
sudo pon dsl-provider
It seems ther's a bug with network-manager, but I'd like to use it again as it easier and NB user-friendly.
I am working to connect several Ubuntu computers to a Hughs satelite radio via a Trednet switch. The ISP requires static IP addresses on our machines. Obviously, to do that I need to access the Network Manager.
When I click on the Unlock button the machines wait for a minute or so and return a "could not authenticate" message. It never prompts for a password.
When I loaded the OS on these computers in the states, there were no issues with the install or updates and configuration. Now that they have been shipped to Africa there is something which has happened to all the computers and they will not unlock.
Configuring a complex network in Ubuntu SERVER is a breeze. Doing so in Ubuntu DESKTOP has been a mess. The obvious culprit is the GUI based network manager. What I want to accomplish: DESKTOP boots up with active networking even before anyone logs in. This would be both wired and wireless. When someone logs in (user or administrator or root), the network manager is NOT started and thus can't mess up the networking.
Multiple IP addresses, including static and calculated, both IPv4 and IPv6. Also some static routes to multiple routers (maybe adding RIP or OSPF in the future). I already made script to do this smoothly in Ubuntu SERVER. Laptop users can still configure their computer for use at home by SOME means, even if command line or a script. It's OK to have to reboot to switch between office and home network.
I'd prefer to leave network manager installed, and just have it not run. But if uninstalling it is the best way to get it out of the way, let me know. So far this is all just Ubuntu, but Kubuntu or Xubuntu might also be preferred by future staff.
Im using ubuntu 9.04. The network manager (at least thats what i think its called, the thing managing network connections that usually resides on the panel in the upper right corner where you can check available connections, log in to VPN etc) has completely disappeared, i dont know what i have upgraded, i usually just click and download all upgrades..Ive tried to re-add it to the panel but i cant even find it there.
I've been fiddling with Ubuntu for the first time ever today and eventually managed to get the drivers for the network adapter installed. Now, I'm trying to get the computer running it onto my home network; I set it up to connect automatically, entered the WEP key, and hit apply, marveling at how convenient it was.
...So far it's still caused me less trouble than some of the the bizarre problems I've had trying to get a Windows computer on a network, but...it just won't connect. At all. It says it is connecting, eventually prompts me for the key again, says it is connecting again, etc, repeat on infinite loop. Except for the occasional times that it stops trying and then, oddly enough, proceeds to state that it is not connected to e of neighbor's network*, which it wasn't trying to connect to in the first place
