Description of problem: For some strange reason, NetworkManager isn’t able to detect the wifi. Windows had wifi services, while it was installed. lspci gives the following component: 02:00.0 Network controller: Broadcom Corporation BCM4311 802.11a/b/g (rev 02) Version-Release number of selected component (if applicable): NetworkManager-0.9.9.0-33.git20131003.fc20.i686 How reproducible: Either GNOME or XFCE (both from Fedora) aren’t able to detect any wifi connection. And there are several ones available here. Actual results: No wifi network available. Expected results: A bunch of wifi networks should be listed as available. Additional info: Please, ask me whatever you need. I guess I filed the bug under the right component.
We need logs and output of several commands in order to find out where the problem could be, Would you please get the following details: $ dmesg $ ip link $ nmcli dev $ nmcli dev wifi NM logs (either in /var/log/messages or sudo journalctl -u NetworkManager) You should also check if the Wi-Fi is not switched off by a hardware button or key combination. $ rfkill list

The firmware for Wi-Fi b43 driver is missing, see the errors in dmesg output: [ 16.540925] b43-phy0 ERROR: Firmware file "b43/ucode13.fw" not found [ 16.540930] b43-phy0 ERROR: Firmware file "b43-open/ucode13.fw" not found [ 16.540936] b43-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all instructions on this website. There is an open firmware in b43-openfwwf package, but unfortunately it only contains ucode5.fw, not ucode13.fw that is required by your chip revision. So you need to install the firmware. The easiest way would be to download this rpm and install it: http://mirror.yandex.ru/fedora/russianfedora/russianfedora/nonfree/fedora/releases/19/Everything/i386/os/b43-firmware-5.100.138-1.fc17.noarch.rpm See instructions here: http://pkgs.org/fedora-19/russian-fedora-nonfree-i386/b43-firmware-5.100.138-1.fc17.noarch.rpm.html Or you can download broadcom-wl drivers from openwrt and extract firmware with b43-fwcutter. http://www.electromech.info/index.php/rhce-linux-howtos-electromech-ahemdabad-gujarat/26-linux-fedora-14-wireless-bcm4311-installation-howto or http://forums.fedoraforum.org/showthread.php?t=269331
Many thanks for your fast reply and your help, Jirka. I solved the problem. So I’m closing the bug myself as NOTABUG. Many thanks again for your help, Pablo PS: I wonder whether NM should be verbose about missing driver. Should I report this upstream?
