lenovo b470 wireless problem in Ubuntu 11-10

[ Edited ]

Hello community, I've just installed Ubuntu 11-10 on a lenovo b470 and the (wireless) network connection doesn't work.

Hardware looks to be working properly: I set the switch on and the corresponding led is on, but I CAN'T state  wireless as available.

 

Apparently Ubuntu had confused Wireless with Bluetooth: Bluetooth appears as ON, but when I set OFF the wireless switch, then Bluetooth becomes as Deactivated.

So, the wireless switch is acting as a Bluetooth switch, turning it On and OFF...

 

¿How can I solve this problem?

 

Thanks in advance

 

   David

Re: lenovo b470 wireless problem in Ubuntu 11-10

As far as i know the first time you switch on the wireless,bluetooth gets enabled too,you need to disable it seperately.So is it not working for you in this way?

Thanks but I have tried that too. If I disable Bluetooth, from the corresponding menu, the wireless switch doesn't turn it on, or off, again, but still the wireless connection doesn't behave as expected.

 

Thanks again.

Re: lenovo b470 wireless problem in Ubuntu 11-10

sudo service network-manager stop

sudo rmmod acer_wmi

sudo modprobe acer_wmi

sudo rfkill unblock all

sudo service network-manger start

sudo rmmod -f acer_wmi

 

then to make it last through reboot

 

sudo su

echo "blacklist acer_wmi" >> /etc/modprobe.d/blacklist.conf

 

or just upgrade to 12.04 it works out of the box then.
