I had a similar problem today on ubuntu 11.10 64-bit, but my platform is an acer 4755g.

1st of all, let's be absolutely sure that your z570 is using a broadcom http://consumersupport.lenovo.com/uk/en/DriversDownloads/drivers_list.aspx?CategoryID=307140

as you can see, z570 supports 1. intel (several diff types) 2. broadcom 3. Atheros

You do this by 1. opening a terminal 2. running the command

alvinh@ibmsda6:~$ lspci | egrep -i "Atheros|broadcom|intel"

This is my other pc which also run ubuntu 11.10, but the i386 version 02:02.0 Network controller: Intel Corporation PRO/Wireless 2200BG [Calexico2] Network Connection (rev 05)

In your question, you were very specific that you have a BCM4313, so i'm gonna take yr word for it. Let's assume that you've done a lspci & it returns "wireless" & "broadcom" on the same line since this is the only hardware that supports 64bit.

  1. Now install this package http://packages.ubuntu.com/oneiric/b43-fwcutter

sudo apt-get install b43-fwcutter

  1. when that's done, goto System Settings (should be on the launcher on the left) Hardware/Additional Drivers -> Broadcom <- Enable this driver

  2. The rest is the same as previous releases of ubuntu; on the top right-hand, click on the LAN & configure your wireless lan info.

Good luck Alex; this is as best as i can do for you bec it's exactly what i did!

This is what helped me:

The Broadcom STA driver under System Settings should be installed. Check if acer-wireless is blocked via

rfkill list all

If it is blocked then edit your blacklist.conf and add following:

blacklist acer_wmi

Then restart and all should work fine. It's strange, but it works without problems.

For those who don't have Internet running on the Ubuntu machine/boot. Download the b43 driver from the above link and then use the following command to install it.

sudo dpkg -i b43-fwcutter_014-9_i386.deb

Replace the filename with the one's you have downloaded move to the folder you have downloaded the file.

Now reboot, hopefully the WiFi is working now.
