Wireless doesn't work on a Lenovo V570

I've had Ubuntu installed on my HD for about 3 months but ever since I ran into this wireless issue I kinda lost my lust of Ubuntu. I have zero experience getting around with/ using the console command. I have a Lenovo V570. I got the driver update for the broadcom networking card via the Additional Drivers application but that did nothing. I love the look and feel of using Ubuntu but I have no technological experience for the matter. Any help would be awesome. When I scan for wireless connections while in Ubuntu, my computer picks up nothing, while on Win7 it will pick up the handful of wireless networks around my area. My wired connection is fine, but the use of not having wireless on a laptop is rather contradictory to it as a feature. Cheers!

Also, I just installed 11.10, if that helps any. Yes, I used the search before I posted this, but again I have ZERO understanding of the command stuff and need a meat and potatoes answer(s).

ok - you most probably have a similar issue as other similar laptop users:

You may be suffering from a clash with the acer-wmi kernel module.

rfkill list all says it is "acer-wireless: soft blocked: yes" then you need to run the following:

sudo modprobe -r acer-wmi

cd /etc/modprobe.d

sudo nano blacklist.conf

Then add blacklist acer-wmi as a new line at the end of the file.

Save and reboot.

Rerun sudo lshw -class network and rfkill list all

You should not be soft-blocked (i.e. rfkill says no to all responses).

lshw should not say "unclaimed" - if it does then use this answer to resolve this.
