Eth0 no wireless extensions. NOTE: Answer below is updated every time new information is added and confirmed working.
Introduction and Background This answer is based on an extensive research done by various Ubuntu users that worked together in almost all issues related to Broadcom. Special thanks to who helped in the Ubuntu forums and on this site with many questions related to Wireless devices and to others who have contributed through E-Mail, chats, IRC and more in testing various drivers with several of the most popular Broadcom Wireless cards (Huge Thanks to Chili555 really. This guy knows his stuff). In total we wanted to offer an answer that could be easy to follow and covered most Broadcom Cards / Drivers. After you follow this guide, you will NEED to test your wireless connection for at least 2 hours (I actually recommend 8 hours) with another device in either Ad-Hoc Mode, Infrastructure Mode or Both. I fixed my problem with the Broadcom bcm4311 drivers. Steps I took for fixing this problem (I stole this method from ): (You may need to install synaptic or your favorite package manager.).
Uninstall the bcmwl-kernel-source package by issuing the following command on a terminal: sudo apt-get remove bcmwl-kernel-source. Make sure that the firmware-b43-installer and the b43-fwcutter packages are installed (of course you will need internet by others means): sudo apt-get install firmware-b43-installer b43-fwcutter. Type into a terminal: cat /etc/modprobe.d/. egrep 'bcm' (You may want to copy this) and see if the term 'blacklist bcm43xx' is there. If it is, type cd /etc/modprobe.d/ and then sudo gedit blacklist.conf Put a # in front of the line: blacklist bcm43xx Then save the file (I was getting error messages in the terminal about not being able to save, but it actually did save properly). Reboot After I did the above the wireless had to be unblocked by rfkill.
This is a common problem to Broadcom wireless chip. Run the following in the terminal: sudo apt-get remove -purge bcmwl-kernel-source If the command run successfully try to switch on wireless (with the hardware key). If it doesn't work or the command failed saying there is no such module, then you could try opening a terminal and type dmesg grep b43 If you see lines like: 17.453421 b43-phy0 ERROR: Firmware file 'b43/ucode15.fw' not found 17.453427 b43-phy0 ERROR: Firmware file 'b43-open/ucode15.fw' not found 17.453432 b43-phy0 ERROR: You must go to and download the correct firmware for this driver version. Please carefully read all instructions on this website. 17.680077 b43-phy0: Loading firmware version 478.104 (2008-07-01 00:50:23) 17.993040 b43-phy0: Radio hardware status changed to DISABLED Then you probably are lacking the firmware for the broadcom card. Open Software Center, search and install the following packages,. b43-fwcutter.

firmware-b43-lpphy-installerer Reboot once. Now the wireless should work. Drivers for the 4313 Let's just enumerate the driver for Broadcom chipsets and how they work with the 4313:. Broadcom STA.
Suggested by additional drivers. Absolute junk.
If you've already installed it, remove it. b43-fwcutter. Lots of people see 'Broadcom' and jump on this but it's not compatible with the 4313 (which is newer). If you've installed it, purge it. ndiswrapper.
Even more flaky than the STA driver. I managed to get it working for about 10 minutes before everything imploded. brcm80211 aka brcmsmac. This is a (relatively) new driver that was recently added to Ubuntu (since the driver was added to the kernel). This should work well and (in recent version of Ubuntu, Natty and Oneiric) should 'Just work'.
This is the droid you're looking for. Use this driver for the 4313. If you're not running Natty or Oneiric, your kernel probably won't have this driver. You need to be running at least 2.6.27 and I'd recommend 2.6.28 as the bare minimum (you can check what you're on by running uname -r). If you're behind on versions, I'd suggest the upgrade but for a quick fix, you can take a look at and try one of those. Installing kernel packages is rarely a risky thing because you can usually just fall back to an old one using the grub boot screen.

You know you're probably on the right driver if you run lsmod grep brc and you see brcm80211 or brcmsmac in the output. Blacklisting your way to success If you're not seeing that, something else has been loaded in and you need to blacklist that. If you can see what has been loaded, great, edit /etc/modprobe.d/blacklist.conf and start adding lines like: blacklist b43 blacklist b43legacy blacklist bcma blacklist ndiswrapper You obviously need to be careful if you have another wireless device that might be using a conflicting driver as if you blacklist it, you'll break that one too:).
