Hey guys,

I have a Lenovo ThinkPad Edge E520 (1143CTO) and I'm having problems getting my wireless NIC to work, as far as I can tell the drivers and firmware are all installed and the device is working.

I have searched around and have done all the fixes I can find online, this is my first 'real' experience with Linux, so patience is appreciated, as is any help I can get. I also had this problem with Linux Mint 11.

It appears that the model of my card is BCM43224, but it doesn't show up anywhere in the with any commands?

sudo lshw


*-network DISABLED

sudo apt-get install b43-fwcutter firmware-b43-installer sudo rfkill list


0: brcmwl-0: Wireless LAN
Soft blocked: no
Hard blocked: no Yet, sudo lshw still shows it as disabled!

Nothing I can find just seems to work. Any help at all is appreciated and I will try any suggestions as-long as you can provide me with the command http://forums.steampowered.com/forums/v4_images/smilies/smile.gif

I have tried EVERY fix I can find!

P.S. This is the fourth forum I am posting it on as I am in desperate need of help.

Thanks.

dmesg | grep -e b43 -e wl
lsmod | grep -e b43 -e wlThe pipe symbol | is on the right side of my US keyboard on the same key with \. Thanks.

acer-wireless: Wireless LAN
Soft blocked: yesThat means, roughly, that software is blocking the wireless. In this case, I suspect the module acer-wmi is not telling the kernel that the wireless switch is on or off.

Hey! Wait a minute! An Acer module on a Lenovo?? Well, it's a known bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/668234

Let's check:
lsmod | grep acerIf acer-wmi is loaded, let's unload it:
sudo rmmod -f acer-wmiDid your wireless spring to life? If so, let's blacklist it:
sudo su
echo "blacklist acer-wmi" >> /etc/modprobe.d/blacklist.conf
exitIf that doesn't fix it, post back and we'll dig deeper.

I... Love... You!

I did see that acer wireless somewhere else on a forum but they seemed to ignore that and it worked?
