No Connection, wireless icon-gone, cannot op"network center"

[Antithesis]

I had this same issue on my new Windows XP (120GB Drive) model. Windows didn't show anything in the Device Manager (the wireless card was gone and there were no unknown devices even after scannning for new devices). I restored the drive to factory state with the built in restore utility and it still did not work, so I returned it. I haven't had it happen on the replacement yet, but any ideas what to do if it were to happen again? Seems to not only be limited to the Linux version.

I had this happen to me like the second day I had it, and I freaked out thinking the wireless card took a nose dive. I found that if you use the little wifi switch, switch it off, then back on and turn off the computer, then start it back up it will restore connectivity. Weird problem though :?:

Hi, I experienced the same intermittent loss of nm-applet as some of you above, and couldn't for the life of me figure out why it would appear sometimes after several reboots, almost at random. In my case, it was because I had the task bar in "auto hide" mode. Taking auto hide off (from the right-click menu: Settings > Panel Manager > uncheck Autohide) allows nm-applet to run on start up. Bit crazy that the application can fail just because the task bar is minimised while it's starting up, but never mind...

Have subsequently noticed that someone else on here also found this (thread: "Network bombshell"). Hope this helps some users with the intermittent problem.

AHH! that explains it. I thought it was only working after restart or wake. The truth is that i would only unhide the menu to see it it worked after restart and wake. I would never pay attention after cold boot. Such odd behavior.

Hi all,

I also had this problem. I found a solution, at least it works for me.

I open the terminal by Alt+F2 and then write "terminal" -> Run.
Then I run " sudo gconftool-2 --recursive-unset /system/networking " to clear all the root network connections.
Then I run " gconftool-2 --recursive-unset /system/networking " to clear all the user network connections.
After doing this, I don't have ANY connection I have been connected previously (be aware).
Finally I reboot and then the network icon appears again but you need to reconfigure the network again (as I said before, I removed all connections).

Hope that this will help.

Everything points to that the last live update was a mistake of linpus (on my version of the AA1).

I solved it by emptying all subdirectories in /var/lib/online-updater including the log (backup first of course) then run live update. Every patch was downloaded again and installed (except the system080805.sh that wasn't supposed to be installed in the first place). It seems to have solved the problem with the erroneous patch. Could have been luck also, that the right files were patched again.

thank you very much! i have the same problem with the liveupdate. it is a real destaster, I will avoid it now.

I've got the same issue, Network icon disappeared from start bar and Network Center doesn't open. I've tried everything in this thread and in the Networking Bombshell thread to no avail, I'm now rebuilding.

I have no idea how this happened, I don't take any of the live updates - this could become a real pain - this is the second rebuild and it's becoming an annoyance. Whilst I put all user files on external media, software and settings I install I lose and have to reset. I'm a Linux newbie, though UNIX I knew from 10 years ago, I was looking forward to getting into it, but this is becoming a minefield. Windoze is not great and on here would be painfully slow, but at least I only rebuild a Windoze machine about once a year, not once a month.

Wow, this fixed it for me. I turned off Autohide, rebooted and the network connection worked immediately. Thanks to both for posting.

I installed this guys (http://blogs.nologin.es/slopez/archives ... l#extended) script and one of the components is to remove the wifi driver before suspend. I haven't had any problem with networking since. I have a Linpus AA1 and the new networkmanager installed (still had problems after installing that one, though). I'm a Linux noob but it seems that in order to get fast startup and shutdown they f...d up on closing/shuttting down the network properly. Hope this helps.
PS I also have the taskbar on autohide and still have no probs.

I fixed mine with this...

no connection? icon gone? cannot op network center?

simply use in terminal

su -
password
mv .gconf .gconf.orig

reboot

et voila!

Thanks kapinouwi!

Hi all,

My AA1 is only about a fortnight old. Never done live update - never hid the bar - the only thing I think I did was let the battery go really flat by plugging in the charger which was switched off at mains. After trying everything posted here this one worked:

I also had this problem. I found a solution, at least it works for me.

I open the terminal by Alt+F2 and then write "terminal" -> Run.
Then I run " sudo gconftool-2 --recursive-unset /system/networking " to clear all the root network connections.
Then I run " gconftool-2 --recursive-unset /system/networking " to clear all the user network connections.
After doing this, I don't have ANY connection I have been connected previously (be aware).
Finally I reboot and then the network icon appears again but you need to reconfigure the network again (as I said before, I removed all connections).

My thanks to muuuuuu

Kind regards to all who contribute.

Upgraded to driver 7.1.6.149 and flashed the bios to 3305. Been on all morning with no dropouts so far (so obviously no lost icon or adapter).

Hello,

I was extremely frustrated at this issue which only seemed to occur after the machine went to sleep.

Anyway, after playing around a bit and running sudo nm-applet manually I then suspended the machine and noticed that nm-applet picked up a SIGPWR signal and then died.

With this in mind, I noticed in one of these posts someone listed to content of the live update which seemed to break it.

I found that commenting out both of the killall statements in /usr/lib/pm-utils/sleep.d/10NetworkManager fixes the issue for me, nm-applet no longer dies after a suspension.

I really don't know if this will cover it for everyone but certainly has worked for me so far.

Good luck!

C.

OK, so this was only half the battle on my Linux version. Every few boots, the wireless just did not work full stop - regardless of which NetworkManager I used.

Seems (to me) the issue is IRQ related, I suspect Acer haven't really tested these devices properly.

Anyway, here's what I see:

When my WLAN does not work, dmesg | grep poll reveals:

irq 18: nobody cared (try booting with the "irqpoll" option)

So, I carefully added irqpoll to my /boot/grub/grub.conf:

kernel /boot/bzImage .... quiet nolapic_timer irqpoll

And so far so good - I'm monitoring though.

Thanks muuuuuu! That worked perfectly for me! I had also had the no Network, nm-applet couldn't run because nothing from keyring-manager etc. (problems seemed to start after a couple of hard freezes and subsequent hard reboots). Used the approach above and reboot restarted the network fine, reinstalled my network details and up-and-running again.

Fantastic!

Zimber.

I fixed mine with this too! Problem came from laptop running out of juice.

no connection? icon gone? cannot op network center?

simply use in terminal

su -
password
mv .gconf .gconf.orig

reboot

et voila!

Thanks kapinouwi!

Thanks for the post i got it working my conection I was going to freak out

 

[tomkerswill]

Amazing... After ages of fiddling about, I finally saw the post on page 7, about switching off the auto-hide on the panel. Unbelievably, auto-hide was completely crippling the nm-applet. It wouldn't even load from the command line. Switching off auto-hide in the panel configuration worked beautifully! Thanks for posting the solution!

So before trying a system restore, I'd recommed switching off auto-hide on the panel.

You'll need to reboot, and then the networking icon should be back. Simple, but effective.

Well my problem is similar, my network manager doesnt appears since last update,and i have tried everything except a full system restore and nothing works , if someone has some other way to fix it please post it if not i will do the full system restore :cry: :cry:

 

[krisk71]

We just got this computer for my daughter for today for Xmas and it was slow etc... when we opened it, could not get on My Space for her. Then all the sudden the icon disappeared. We can not also click on Network Conn - nothing happens. I am trying to run system recovery disc right now from an external drive I purchased- but I am really upset- this is a brand new computer!!!!! Daughter is upset- told me it is junk to return it UGH!

 

[steven1314]

Looking at the previous threads some people have tried to unblock task bar. Please please please can someone help me to do this. It said to right click and open up panel but I have tried right clicking everywhere and can find it. Bought Acer for my wife could use it fine for 2 days and now can't find icon to log onto wireless router. Just looking for someone to help me with a solution. I am not technical and all the jargon is confusing. Can anyone out there help me with some simple instructions.

Thanks

Steven

Worked for me. Saved me from reinstalling Linpus and loosing all the mods.
I recommend everyone give this a try before anything else
