[SOLVED] Wireless is ON but cannot find any network?

Post by kinghadi »

Hi
I'm using Linux Mint 17(Xfce). My wireless worked properly until a sudden shutdown of my laptop caused to make some problems. Now my wireless is On("enable networking" and "enable wifi" is available and also my wireless led is on) but it cannot find any network! I don't have any cable connection in my linux and currently I'm using windows to ask my question.

I don't know what happened ? I have to mention that before sudden shutdown, I created a pppoe connection to access internet for a specific network and it worked well. I don't know whether pppoe connection make the problem or the sudden shutdown? I used

Code: Select all

/etc/init.d/networking (start/restart/...)
but it didn't help! Can anyone help?
Thanks in advance for any comment!

I suppose that the DNS-settings are missing or the wrong. Run command

Code: Select all

nm-tool
.. and tell the result.

I solved the problem :) .. thanks for the

Code: Select all

nm-tool
.

First step:
As you can see the state for wlan0 is unmanaged:
State: unmanaged
edit the file
/etc/NetworkManager/NetworkManager.conf

Code: Select all

sudo gedit /etc/NetworkManager/NetworkManager.conf
and change it from
managed=false
to
managed=true
then restart the network-manager service:
sudo service network-manager restart

Second step:
The problem raised from pppoe connection. so the second step is to get rid of it. edit the
/etc/network/interfaces
file:

Code: Select all

sudo gedit /etc/network/interfaces
and make to have only the following line:
auto lo
iface lo inet loopback
the problem will be resolved. I followed the solution provided in here: http://ubuntuforums.org/showthread.php?t=1998634
