Acer Aspire Timeling 5810TG Wireless problems (modem-manager)

[airplanesimen]

When booting my computer, my modem-manager wont connect to any networks, because it's failing to load properly upon booting.
When i tried to enable networking when in safemode, i got this output, and it stayed like that for over 5 min:







When i am in Unity, without safemode, i can see the icon for the networking on the bar flickering. It stays there for like 5-10 seconds, and dissapears, and then comes back. The popup is appearing all the time that i am not connected to any networks.
And when i click the icon in order to watch the dropdown-menu, nothing happens.

if I am entering the system tool called "Networking", it tells me this:
"The Networking-service on this system is not compatible with this version".


BUT
Sometimes, when i reboot my computer, the network is working all fine, nothing wrong. But, that is extremely rare, so i am most often expereiencing that it doesn't work.


I am Running ubuntu 13.04 with Unity on an Acer Aspire 5810TG with the Intel WiFi Link 5100 / Bluetooth 2.0 EDR, 802.11 a/b/g/n (draft).



Thanks for any help i might get. Can provide more info if needed.

Uhm well,
If i do:

sudo killall modem-manager

and then

sudo modem-manager

It says

could not acquire the org.freedesktop.modemmanager service as it is already taken

When booting my computer, my modem-manager wont connect to any networks

Any networks?? Is this a modem or a Wireless card/adapter? Modem and wifi are different things and are managed differently too (although the same GUI application - NetworkManager usually handles them just fine).

if I am entering the system tool called "Networking", it tells me this:
"The Networking-service on this system is not compatible with this version".

This most probably indicates an incompatible entry in /etc/network/interfaces file. Please post the outputs of -

cat /etc/network/interfaces
nm-tool

And if it is a USB modem/wifi adapter, the output of -

lsusb

If it is an internal PCI one, then the output of -

lspci -nnk | grep -iA2 net

Hmm.. please try -

sudo service network-manager stop
sudo service network-manager start

Does it enable the Network Manager icon on the top right of the screen? Can you connect after this?

If connected, please do -

sudo apt-get clean
sudo apt-get autoremove
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install --reinstall network-manager network-manager gnome

..and reboot. Does Network Manager start automatically after this?

[airplanesimen]

Nope, that's my problem:

I started the service again, and the icon appears (blank, when it's not connected). The dialog that tells me : "Disconnected - You are now offline" shows, and i can't click the icon either, because nothing happens at all.

No networks connected either.

[varunendra]

When the icon appears, does "nm-tool" start returning normal outputs? If yes, please post -

nm-tool
nmcli con

Does your wireless connection show up in the last command's output? If yes, you may try -

nmcli con up id <your connection's NAME>

where NAME is the connection name that appears in the output of "nmcli con".

However, if your connection is not saved (so does not appear in "nmcli con"), you may try this method to manually connect : http://askubuntu.com/a/55832 - just to be able to do the updates and re-install NM. I hope it should be fixed itself after an update --> reinstall.

Oh, and to try making the nm-applet (the NM icon on the top right) clickable, you may try this -

killall nm-applet

Then press Alt-F2 --> type "nm-applet" --> press "Enter". The above command will remove nm-applet, and this will bring it back, functioning properly this time if the background services are fine.

Well, there was some difference in the nm-tool output, but i did the same cmd many times, and it changed from that output and the first one i posted earllier. Btw, the icon is flickering (it dissapears and appears constantly, looks like network-manager is having a rough time.)


BTW: the icon is still not clickable, but the others are.
And as i said, it keeps dissapearing.

[varunendra]

Yup, because the package network-manager is clearly broken. Please try this alternate method to re-install it -

apt-get install --print-uris network-manager network-manager-gnome

This will give you the download URIs of the required packages. Copy-past these URIs and use them to download the packages on another system where you are posting from.

Once downloaded, copy them back to your Ubuntu desktop, in a new folder named "nm" (just to avoid confusion), then open a terminal and do -

sudo apt-get purge network-manager network-manager-gnome
cd Desktop/nm
sudo dpkg -i *.deb

Let me know if there are still errors. If not, you should have a working nm-applet icon (may require you a reboot or logout re-login)

[airplanesimen]

No errors setting up the packages now.

But still, the same error as earlier when doing nm-tool, and the icon is long gone.

I am kinda stuck here.

AND the icon is flickering even faster now than before. Weird.
