How to get Broadcom BCM 43XX Wireless card working

I've installed Ubuntu 11.10 on an Asus 1015PN netbook with 2 gigabytes memory using WUBI.

Got a Broadcom 4313 chipset (14e4:4727).

I wanted to connect my netbook to my mobile using Joikuspot premium and I was able to scan and find the wireless AP but wasn't able to obtain an IP so I set a static IP and disabled ipv6 without any luck.

Then after reading a post I installed the broadcom wireless source, common and the firmware (brcmwl-kernel-source) using synaptic. After uninstalling the previous brcm sta driver which was downloaded form here.

After rebooting the system I did a iwconfig and was not able to find the wlan0 interface which was there before, so I removed the drivers that I installed and reinstalled the old broadcom sta from their site, however I am still not able to find the interface but Ubuntu recognizes my WLAN card when I do a lspci.

How do I get wlan0 back?

You must delete all drivers for this Broadcom and then:

apt-get install bcmwl-kernel-source
echo blacklist acer_wmi >> /etc/modprobe.d/blacklist.conf

  • Thank you, I found that there were two drivers which were conflicting with each other, so i removed all the broadcom drivers, reinstalled and blacklisted a few drivers with the instructions given here. But its back to the same situation once i restart, how do i make this permanent?
