I got a Lenovo Thinkpad z570 yesterday with Ubuntu 11 installed. One major issue is that wireless does not work.
"Wireless is disabled by the hardware switch" is the status in Network Manager. Wired ethernet works.

I googled this message and there are many posts specific to this issue. But none of the workarounds enabled wireless
The following are some details. Has anyone faced this issue or have a solution?

david@david-Ideapad-Z570:~$ uname -a
Linux david-Ideapad-Z570 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011 i686 i686 i386 GNU/Linux

david@david-Ideapad-Z570:~$ lspci |grep Atheros
02:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

david@david-Ideapad-Z570:~$ rfkill list
0: ideapad_wlan: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
1: ideapad_bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
2: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: yes
3: acer-wireless: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
4: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

This process enables wireless till the next reboot

sudo service network-manager stop
sudo rmmod acer_wmi
sudo modprobe acer_wmi
sudo rfkill unblock all
(Checked that everything was unblocked)
sudo service network-manager start

Now, instead of "Wireless is disabled by the hardware switch" status
in NM, the message will be "wireless is disabled"
Enable wireless from NM
sudo rmmod -f acer_wmi

Wireless networks will be detected and connected

To make this change permanent,
sudo su
echo "blacklist acer_wmi" >> /etc/modprobe.d/blacklist.conf
exit

Greetings David,

I have just booted up ubuntu on a Lenovo ideapad v570 and am facing
the same situation.  This is my first experience using Linux.  Could
you explain how to get to where these commands are typed in?  Thanks
for the post!

Chris,

Right On,

Thank You for your help.
I actually have no experience with Linux, this is a new computer
purchased after my faithful Macbook recently died for good(bought new
in 2001!).  So I have up to this point, after owning a Mac for 10
years, no deep computer experience,  I went with Linux because Windows
is disheartening and Apple is cool but still corporate.  I have read/
looked at a couple of books from the library(Just Say No to Microsoft,
Linux for Dummies, etc.)
This is a new lenovo v570 running ubuntu 11.04.  The computer was
purchased yesterday and booted up with Windows using Google Chrome as
a browser to download Ubuntu.   This was done wireless.  After
rebooting with the new operating system the wireless is not
functioning.  This sounds like the problem described.
So, here is what I learned:
 -the terminal can be accessed from “ctrl-alt-T”,  or through “the
dash” in the upper left of the desktop.
 -passwords apparently don't appear, but are there when you hit
enter.  Chuckle.  Oh well ,that is a lesson I won't forget.
-that I can do stuff with this box to do other stuff(with a little
help from my friends)!
So Thanks to You All again.
So, back to the forums and tutorials to learn some more.
All the Best!
-Chris

I got a v570 two days ago and have had the same/similar problems.  At
first I thought it was just a driver issue with Ubuntu; however,think
it's more than that.  After 6 hours of fighting with Ubuntu, searching
google, and having no luck, I gave up and re-installed Windows 7.
Luckily, I had backed up all of the drivers and got everything back up
and working until I installed VMware to run Ubuntu and Backtrack 5 and
lost my internet connection.  I uninstalled VMware incase there was an
issue with the Adapter configurations and double checked the drivers.
The hardware radio switch is turned on, FN + F5 isn't working and the
computer is still saying that the switch is turned off....I have
rebooted several times to be sure that everything worked itself out,
hard-wired into the router to check for hardware changes (none), and
still nothing.  I might just return it to bestbuy and upgrade to
something better....

Matt,
