Hi,

could give me the output of

Code: Select all

iwconfig

Code: Select all

sudo service network-manager stop

Code: Select all

sudo rm /var/lib/NetworkManager/NetworkManager.state

Code: Select all

sudo service network-manager start

[Zeroni13]

iwconfig:

Code: Select all

lo        no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=0 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:on

Code: Select all

          
sudo service network-manager stop
network-manager stop/waiting

sudo rm /var/lib/NetworkManager/NetworkManager.state

sudo service network-manager start
network-manager start/running, process 2343

and did the netwrok applet start on the bottom right corner?

[Zeroni13]

Yes, but when i flip the Wireless switch it jumps back.

[PatH57]

what do you mean with it jumps back?

[Zeroni13]

The button marked Wireless in the connection manager on the taskbar, when I toggle it on it just goes back to off automaticly.

[PatH57]

try this an restart
Code: Select all
sudo nano /etc/NetworkManager/NetworkManager.conf


In that file, change the line that says managed=false to read managed=true

Then, the following two commands restarted the Network Manager service, allowing the applet to work properly:

Code: Select all
sudo service network-manager stop
sudo service network-manager start

[Zeroni13]

Still behaves the same way.

[PatH57]

ok ,

check your kernel version

Code: Select all

uname -r

[Zeroni13]

3.16.0-999-generic

[PatH57]

you are using a release candidat kernel and wonder why some stuff doesn't work correctly?

[Zeroni13]

Well, I tried using that one because the 3.13 didn't work.
Back on 3.13.0-24-generic now, still does not work.

[PatH57]

doesn't really surprise me.
If the driver was not properly installed on the first kernel chances are it will not work once you update this kernel....

rfkill list




dmesg | grep firmware


and post back

[Zeroni13]

$ rfkill list

Code: Select all

lsmod

[PatH57]

do you have anything in additional drivers (control center driver manager)?



Also try reloading your bios settings (part of the reserved memory is used by addon cards)

[JeremyB]

Are there any wifi switches on the laptop for disabling wifi or any options in BIOS?

Code: Select all

ls /lib/firmware/ | grep iwl

And this might work

Code: Select all

sudo modprobe -rv ideapad_laptop

[Zeroni13]

Code: Select all

 sudo modprobe -rv ideapad_laptop 

actually did the trick.

Thanks to both of you!
