lenovo b470 wireless problem in Ubuntu 11-10

[dleyval]

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

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.

what network card does your laptop have?

[kschumake83]

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.
