====== WiFi Kernel Driver ====== During the UP7 system upgrade, a message appeared saying: <wrap box center 85%> This system is currently running Linux 3.2.0-4-amd64 and you are installing Linux 3.10-2-amd64. In the new version some of the drivers used on this system may require additional firmware files:\\ \\ b43: b43/ucode9.fw, b43/ucode5.fw, b43/ucode16_mimo.fw, b43/ucode15.fw, b43/ucode14.fw, b43/ucode13.fw, b43/ucode11.fw\\ \\ Most firmware files are not included in the system because they do not conform to the Debian Free Software Guidelines. You may need to reconfigure the package manager to include the contrib and non-free sections of the package archive before you can install these firmware files. </wrap> Of course it all depends on the hardware you're using and you might get a different warning, or none at all. In this case, the b43 warning, referred to the Broadcom wireless chip that resides on the WiFi card inside the MacBook. Information regarding this particular driver can be found here: [[http://wireless.kernel.org/en/users/Drivers/b43]]. ===== Install the Correct Firmware ===== After looking around to understand exactly what had to be done, it finally appeared that a simple apt-get install was possible to get the correct driver: <code> sudo apt-get update sudo apt-get install firmware-b43-installer </code> It might be needed to reboot your system in order to have the new driver available. <code> sudo reboot </code> **WiFi should be available**: after rebooting, clicking the "network" icon in the panel should show a list of available SSIDs: {{ :install:fixes:wifi-menu.jpg?direct&200 |}} Select one, and you'll be asked for the access password of the channel. ===== Other Firmware Installations ===== In my case, it was the only firmware update I had to carry out, I'm of course interested in hearing from your experience also !
