Read the Debugging section below for more information regarding this wireless device. There were some changes and some drivers will only work with this package. Remember to have a clean system before installing it:. In some particular cases, after installing the firmware-binstaller you need to remove the b43 module, enable it again and even proceed to unblock with rfkill:.
If you have a Broadcom card that has a different pci. Once solved, the solution will be added to this howto. To install firmware-binstaller offline see this answer. For cases where you need to install bcmwl-kernel-source but you are offline, here is an excellent answer about it. But basically follow this steps:. To give an example, after going to point 1 mentioned above, If you had the Broadcom 14ea0 , you would search for the bcmwl-kernel-source package and after selecting the corresponding Ubuntu version In my case On this page I would select the corresponding architecture 32 or 64 but would also need to download the 3 package dependencies mentioned on that page as seen in the following image:.
After downloading all packages and dependencies, you can proceed on copying all packages to a single folder and running the dpkg command as mentioned on step 4 above. This applies for cases, for example, where the bcmwl-kernel-source is already installed but the driver does not yet work. The following information is additional material to read about solving various issues related to Wireless Management and conflicts with other Network devices. Know that it some cases you need to have an updated Kernel version, since each new version of the Kernel introduces either new Network drivers, improvements over existing drivers or solves bugs regarding them.
Before reading the points mentioned below, be sure to have all repositories enabled on your Ubuntu system. To check, run on the terminal software-properties-gtk and make sure all options on the Ubuntu Software Tab are enabled. Make sure the Wireless card is not hardware disabled. To configure your wireless devices through the terminal I recommend How to connect and disconnect to a network manually in terminal?
If your connection drops every so often some users have suggested to set IPv6 to Ignore. Just go to Network Manager The network icon on the top panel.
Click on it then select Edit Settings. Then go to the Wireless connection you are using, select it. Now go to the last Tab in there that mentions IPv6 Settings. In the Method field select Ignore.
If your laptop does not detect your wireless card some users have mentioned that using rfkill unblock all will solve the problem.
Others simply turned the WiFi switch on their laptops off and then on again Physical switch available on this laptops. If it works then add it to you RC files so it is executed every time you boot. You can change PIO to 1 if you need to it. For all Wireless cards in general, it is very important to also take into consideration the network devices you are using Routers, Switches, Wireless Channels and Wireless Bands, etc..
With this information you will be able to evaluate better what the source of the problem could be when you arrive at a dead end. Even after installing the correct driver the user would end up in a "trying to connect" loop.
It would see the wireless SSID but when trying to connect to it, it would enter an reconnecting loop. The solution was that this particular wireless device did not support 40 Mhz channels nor does it support The router in that case was actually broadcasting with a forced 40 Mhz and on WiFi-N only. This is a case scenario that also repeats in other cases, so a proper evaluation of the network equipment would help a lot.
This can happen with modern Routers that have the ability to extend the wireless connection by offering the same SSID. If your connection drops very often, it means you are almost in the middle of both router devices. To lower or eliminate the dropping rate of your wireless device, try to position yourself where your wireless card can see only one router or at least one of the routers has a higher signal strength than the other one.
There are also some techniques to force the wireless device to only connect to a specific router by setting the BSSID to the MAC Address of the router you wish to connect to. This will force your wireless device to ONLY connect to it. On some specific scenarios, installing the drivers, be it in offline mode through various DEB packages or through apt-get with internet access, will not work if Secure Boot is not disabled.
This is because the access needed is denied by Secure Boot so the drivers will look like they are installed correctly when in fact the did not. On other cases looking for and installing the latest Linux Firmware would solve the issue. Either solving minor problems that were happening with a working card or making the card work for the first time. Uninstall the bcmwl-kernel-source package by issuing the following command on a terminal:.
Make sure that the firmware-binstaller and the bfwcutter packages are installed of course you will need internet by others means :. Then save the file I was getting error messages in the terminal about not being able to save, but it actually did save properly. After I did the above the wireless had to be unblocked by rfkill: How to unblock something listed in rfkill? Broadcom STA. Suggested by additional drivers.
Absolute junk. Skip it. If you've already installed it, remove it. Lots of people see "Broadcom" and jump on this but it's not compatible with the which is newer. If you've installed it, purge it. Even more flaky than the STA driver. I managed to get it working for about 10 minutes before everything imploded.
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. Google for that specific hardware and Ubuntu. Both Broadcom and and Dell product names are described. Guten Abend. ID est This is the droid you're looking for. I had tried several solutions posted on the web for other Broadcom devices but they didn't work.
En los resultados que aparecen aproximadamente 10 , borrar todos los relacionados con la placa de red BroadCom. Corrupted or outdated device driver could be a reason for Broadcom Click button to download broadcom-wifi-driver-ubuntu. Both the b43 and b43legacy drivers conflict with the broadcom-wl driver, otherwise known as Broadcom's Contents Broadcom Corporation.
It is a driver which allows you to use windows drivers. Broadcom Corporation BCM One of the dependencies of brcmsmac is bcma. If you're using brcmsmac, see the last entry here for compiling the backports module This device is using an alternative driver. So with same hope.
Use the latest kernel. In order to get this to work I had to remove it from the blacklist. Login in assuming acer wireless module gets loaded and select Enable Wireless from network applet 2. This will allow you to use the specific wifi driver for your computer. If you have a pop-up blocker enabled, the Update Details window might not open.
Kenne mich leider nicht so aus, wenn ich es aber richtig verstanden habe, solll ich die beiden txt-Files, die ich mit OLT erzeugt habe hier rein kopieren. How and why it gets named bcma-pci-bridge, I have no idea.
