Unable to get wireless to work

Asked by joe brown

I am unable to get my wireless to work. Here is some output data if someone could take a look at it and let me know what may be the issue. I am able to get wired network access and wireless works on Windows.

Here is the output

You need to supply the Broadcom firmware by installing the b43-fwcutter package. Accept the offer to download the appropriate Broadcom files, the firmware will be placed in /lib/firmware/b43, and hopefully, wireless should then work. There may still be a problem with the driver, but put the firmware in place first. Two drivers are available, your 4311 chip will work with both. I use the open b43 driver, but that does not work with some newer chips.

The error "b43-phy0 ERROR: Firmware file "b43/ucode5.fw" not found or load failed" means that b43-fwcutter is not installed yet on your pc. And that means that the Broadcom firmware for your wireless card is not loaded or installed yet.

Step 1: Open Terminal from "Applications->Accessories->Terminal"

Step 2: Please copy-paste the following 2 commands into the Linux Terminal. Press <enter> after each command.

sudo apt-get update
sudo apt-get install b43-fwcutter

b43-fwcutter exists in the Ubuntu repositories, but you will need a working Internet connection in Ubuntu in order to locate it and install it. Use a wired connection to get b43-fwcutter installed.

After installing b43-fwcutter, please reboot and then retest wireless.

I have seen this Broadcom error message so many times before. The reason why the Broadcom wireless driver does not work out-of-the-box in Ubuntu , is because the firmware for your wireless card is proprietary.

The firmware files for your wireless card are not allowed to be included as part of the default Ubuntu install, because it is non-free software.

Thanks for the help guys. After some time I found out I needed the following firmware file updates

from
https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#b43%20-%20Internet%20access

downloaded
On a computer with Internet access, download the required firmware files from http://downloads.openwrt.org/sources/wl_apsta-3.130.20.0.o and http://mirror2.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2

Thanks again this forum is great.
