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 If you're not running Natty or Oneiric, your kernel probably won't have this driver. You need to be running at least 2. If you're behind on versions, I'd suggest the upgrade but for a quick fix, you can take a look at the mainline kernels 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 brcm or brcmsmac in the output. If you're not seeing that, something else has been loaded in and you need to blacklist that. 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 :. If it doesn't work or the command failed saying there is no such module, then you could try opening a terminal and type.
Then you probably are lacking the firmware for the broadcom card. Open Software Center , search and install the following packages,. Now it's working wirelessly. You don't need to follow the above steps. Install the "B43 driver" for wireless. Install the firmware-binstaller package. First uninstall the proprietary driver from 'additional drivers". You can either restart your pc or if this is a pain type the following commands in the terminal which will 'switch on' your wireless.
Finally I've solved the problem myself, but I'm not sure how. I was about to compile the driver with the source from broadcom. On Ubuntu, you will need headers and tools. Try these commands: apt-get install build-essential linux-headers-generic apt-get build-dep linux. I'm not sure of what I've done. I guess it builds kernel or driver dependencies or both. The BCM driver needed this step and the jockey self-configuration omitted it for some reason.
When that happens, first check if your card is indeed supported by the STA driver, and to do that, open a terminal window ctrl-alt-t and run. If the card is supported, try installing the driver manually.
Open a terminal window ctrl-alt-t , and run. To be clear with referencing the different IDs, make sure to consult the STA link above prior to reading on, and comprare to yours via:. The description below has been applied to the STA driver but has been written before this.
Although Ubuntu is meant to be versatile, beautiful, and easy to use for everyone, packages still are prone to dependency faults. Look, installing drivers and other system stuff, it's reasonable to get as verbose a feedback as possible, i. I've been experiencing the same issues with my Let me offer a blunt and partly non-analytical solution:.
In such case, which I assume happens quite often, since 1 The inherent dependency isn't resolved and 2 There's a break in the wl interface upon upgrades which may involve a kernel update , in such case, you should simply do the following two steps and I assume you don't need to reinstall the WiFi driver sources:. After this command you should see as this has been deferred upon incapacity to compile during the installation procedure of the STA WiFi driver source files :.
I'm not sure whether the guys responsible for packages would get to see this. Still, having used Gentoo for years, I've got used to its verbosity and which may seem unnecessary coloring and formatting of output.
You guys should add formatting and colors to your apt-get routine, it's so much easier, especially for novice users, to understand what may have gone wrong. And add the headers dependency, you could remove them afterwards--and surely you'd have to rebuild the module upon kernel change. I hope this helps, and I'm cautious of generalizing the above path to resolve the mass issue. Just give it a try, if it works, awesome, if it doesn't there are so many more solutions offered which are notably more analytical and proficient.
For pci. And I've also missed the fact that Ubuntu offers a link in the packages to the currently installed and running kernel and headers version in order to avoid defining the kernel version.
Step 3 was a key step for me. If you don't remove original Wireless STA driver, you'll run into problems. I had tried several solutions posted on the web for other Broadcom devices but they didn't work. Unfortunately, the wireless card is off whenever I reboot, so I created a script with the above two modprobe commands to execute whenever I reboot. This will have to do until Ubuntu The first makes sure that the sta driver is in place, the second and third blacklist the two drivers brcmsmac and bcma which clash with the correct sta driver.
I first thought I would edit Luis Alvarado's excellent answer see his post on september 7th, , because when I followed the steps, it appeared the package that is indicated in the table see his post for my PCI. ID does not actually correspond. In fact, my PCI. ID is 14e , which, according to the table, requires the installation of the package bcmwl-kernel-source. This package was perviously installed on my computer, but the Wifi wasn't working no detection of any wireless network, since the upgrade to Ubuntu I instead tried to install the firmware-binstaller following Luis Alvarado's answer using firmware-binstaller is an alternative already pointed out in his post , and it worked!
Install the firmware-binstaller package and not the bcmwl-kernel-source package contrary to what is advised in the table for 14e rev 01 :. The issue with your wifi is that you are using the one forced by Ubuntu, but that does not work. Run the following commands to get the Wifi properly working:. Dell Inspiron E, the following steps alone , worked for me. I had to undo the extra steps of editing the blacklist file.
In the case where either the blacklist. Good news. Based on the info you've provided in the comments, you have a network card supported by the proprietary Broadcom driver. First, make sure you've ran sudo apt-get update from the terminal. Then go to "Additional Drivers. Is the Broadcom non-free driver turned on there? If not, try to enable it and restart your system. If that doesn't work, try to reinstall the drivers just to get online once manually.
That was that until the next reboot. Now I had to find out how to re-enable it but now the problem lies somewhere else.
This package contains Broadcom There is a much easier way of solving this problem. The trick is the order in which you install proprietary drivers. I enabled the ATI Raedon driver first then the Broadcom driver this lead to the errors mentioned above.
I had wireless. Then I installed the ATI driver and now both work. Make sure you're not having an unresolved linux-headers dependency, cf. After upgrading to Ubuntu Here I : First I uninstalled bcmwl-kernel-source Then installed firmware-binstaller and bfwcutter which rebuilt the wifi drivers. With rfkill I can see:.
With the STA driver I can search the network, but the connection never finishes. The system worked fine with Ubuntu It seems like the firmware files are missing from the Linux drivers? For anyone else who is getting the "wireless is disabled by hardware switch -a" message under wireless you'll see it by clicking on the icon - and it's "hard block", that may work in any model that is working for me in netgear "wireless USB adapter", haven't checked the others, but it may work.
First check if it hard-blocked. Then I shutdown my PC, disconnected it from electricity and opened its left door. I removed the cycled battery and hit the power-button 20 long and short presses to reset the BIOS. Then I returned the battery and connected the PC to electricity. I pressed F10 to save settings and restarted. After all this, the system was ready--desktop and its files. I waited for a while and the Wi-Fi was responding again.
That have already worked for me four times it may happen any time you are forcing a shutdown or disconnecting the Wi-Fi. I have a b43 card and have been using Ubuntu with it since 9.
It involves some command line usage but believe me it's worth it. I assume you know the type model of your wireless card. This method does not use the Additionals Drivers way. After you've uninstalled bfwcutter reboot your computer.
NB if you've no access to a wired network on your machine you will need to download the bfwcutter package manually from here , as well as your card's driver from here.
My card is the so I download the broadcom-wl Once you have reinstalled bfwcutter either by running sudo apt-get install bfwcutter or by using the. Then run. I found the light wouldn't come on when I switched it to the op position.
A utility you can try is rfkill to get it to come on. You have to do this every time you reboot. Ubuntu Community Ask! Sign up to join this community. The best answers are voted up and rise to the top. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Product: Broadcom Operating System: Microsoft Windows 10 bit. Hello, I have a Broadcom Do you know if there is a Windows 10 driver for my card somwhere? Firmware is not packaged by the Debian Project. It must be downloaded and extracted, which can be performed by the firmware-binstaller , firmware-b43legacy-installer or firmware-blpphy-installer packages during their installation.
An Internet connection is required. Just add " contrib non-free" to the end of your existing line. When satisfied, the relevant Broadcom proprietary driver will be acquired, the firmware within will be extracted and installed. If not already performed, connect the device to your system.
