I just installed Wubi on a Dell Inspiron, and am trying to install the drivers for a Broadcom BCM4312 driver. I know this is a common question on the site, but I think I have tried every solution posed, and I still cannot get it to work. When I go into the jockey file, I get:

2013-08-24 17:10:10,049 DEBUG: BroadcomWLHandler enabled(): kmod disabled, bcm43xx: blacklisted, b43: blacklisted, b43legacy: blacklisted

I went into the blacklist.conf file and commented out

# blacklist bcm43xx

And I have restarted, even done a fresh install of Wubi. Nothing works. Any suggestions? Let me know know what further info I need to provide.

Based on request for further feedback, I ran this command:

lspci --n -d 1434:

And got the response:

0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

For further information, I uninstalled wubi and installed Ubuntu 12.04 on a new partition of my hard drive (I thought that might help with the driver issues), but I'm having the same problem.

I am able to connect an ethernet cable to get internet directly onto the machine. And, when I had Wubi installed in a previous installation on the same machine, I was able to somehow get the wireless to work, so I'm pretty sure it can be done.

For jockey to work, it needs an active internet connection, was it available? – mikewhatever Aug 24 '13 at 21:30
Please edit your question to add details of your wireless card from the terminal command: lspci -nn -d 14e4: – chili555 Aug 24 '13 at 21:44
Better would be to read the answers here the first and the second (from top to bottom) and add some additional info to your question. – NikTh Aug 24 '13 at 23:08

Unfortunately, this is a bug reported years ago

This is what you can try

Solution 1

sudo apt-get install --reinstall bcmwl-kernel-source


Solution 2

Remove bcm-kernel-source, if present

sudo apt-get purge bcm-kernel-source

Make sure you got this installed (otherwise, install it)

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

Then, run

cat /etc/modprobe.d/* | egrep '8180|acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl| lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3 |rt6|rt7|witch|wl'

If you see something like this

blacklist bcm43xx


sudo gedit /etc/modprobe.d/blacklist.conf

If you don't have this anymore, then add the # again, to look like this

# blacklist bcm43xx


Keep in mind that this is a unfixed bug, so neither of these solutions might work for you.

I believe bcmwl-kernel-source is incorrect for his device. We need the identifier 14e4:43?? before we know for sure. – chili555 Aug 24 '13 at 22:04
Yes, you're right. I started looking for solutions to this problems, and bcmwl-kernel-source appeared in all of them. – 0R10N Aug 24 '13 at 22:25
...but the bug report was filed against BCM4311, and not BCM4312. I've been using BCM4312 802.11b/g LP-PHY [14e4:4315] with the STA driver for years, while b43 has been buggy. – mikewhatever Aug 25 '13 at 8:54
chili555, I added further information in my answer above. any suggestions? – linux_guest Sep 8 '13 at 17:43
