Wireless doesn't work on a Lenovo V570
Solution 1
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.
Solution 2
I had the same problem on a Lenovo B570, for some reason when you install Ubuntu 11.10 it switches off the wireless. You have to blacklist the acer-wmi as listed above then boot back into windows and turn on wireless in windows systray then reboot back into Ubuntu and walaa. Don't know why, just know after installing both Mint 11 and then Ubuntu 11.10 it is the only way it would remove the "softblocked:yes". Found this quite by accident needing wireless.

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).

mikewhatever over 12 yearsThanks for the outputs. The driver for you BCM4313 wireless card doesn't seem to be installed. Can you try the Additional Drivers again, and make sure you are connected to the internet wiredly.
-
Stephen over 12 yearsSo I removed the BCM4313 Driver from the Additional Drivers application, then re-activated it. Afterwards it scrolled me to a black terminal screen and then froze. Now whenever i try to boot in Ubuntu, it fails to get any farther than the Ubuntu purple/orange blend background. Should I completely delete Ubuntu from my disk and start from scratch?

Stephen over 12 years'stephen@ubuntu:~$ rfkill list all 0: ideapad_wlan: Wireless LAN Soft blocked: no Hard blocked: no 2: phy0: Wireless LAN Soft blocked: no Hard blocked: no ' whatever it is that im doing to enable wifi over and over, after typing rfkill list all, 1: acer-wireless disappears. How do you save? -.- nublet here.

rfkill
will just report whether you have any software blocks or hardware blocks on your wifi - there is no need to save anything. By addingblacklist acer-wmi
intoblacklist.conf
prevents theacer-wmi
module from loading and hence prevent "wifi-blocking" -
Stephen over 12 yearsbut everytime i reboot my computer i will have to re-enter this? this is the effect I am getting.
