11.10broadcomlenovowireless
Help please. Put it on the computer ubuntu 11.10 64bit. Used the response in the topic WiFi does not work, Broadcom STA Wireless driver does not work on a BCM4313 but this does not help. Computer Lenovo z570, wifi card Broadcom Corporation BCM4313
When choosing Network Manager > Enable Wireless nothing happens. WiFi not enabling.
OLi I found this tutorial which install the same card which you have in ubuntu forums .. i think is the right solution for your problem :
New brcm80211 driver guide for Broadcom wireless cards
Updated :
"Download and copy the device's firmware", i have the solution for that :
when you execute these 2 commands :
git clone git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
git clone git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git
it created two folders in your home directory :
1.- linux-firmware
2.- linux-next
these files are located in :
cd ~/linux-firmware/bcrm
Make sure the proprietary broadcom driver is not loaded
You may be suffering from a clash with the acer-wmi kernel module.
rfkill list all says it is "acer-wireless: soft blocked: yes"
try 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 rfkill list all again - if there still is a "hard-block" you have disabled the wifi via a switch or a Fn key type wireless on/off.
On some laptops the hardware switch can be quite small to find - check your laptop manual.

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.
sudo apt-get install b43-fwcutter
when that's done, goto System Settings (should be on the launcher on the left) Hardware/Additional Drivers -> Broadcom <- Enable this driver
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!
