You have been subscribed to a public bug: There is a problem with this kernel I have reported this problem to Debian as well. The kernel is not able to load the firmware for the wifi hardware so the network managers are not detecting wifi at all. I tryed to run the nm-applet and got the following error:
(nm-applet:30837): Gtk-WARNING **: 18:26:47.538: Can't set a parent on widget which has a parent The correct firmware files for my system are installed and in the correct place.When I run a dmesg command it gives the following error: 9.453407] b43-phy0: Broadcom 4312 WLAN found (core revision 15) [ 9.496761] b43-phy0: Found PHY: Analog 6, Type 5 (LP), Revision 1 [ 9.496777] b43-phy0: Found Radio: Manuf 0x17F, ID 0x2062, Revision 2, Version 0 [ 9.512936] b43 ssb0:0: Direct firmware load for b43/ucode15.fw failed with error -2 [ 9.512976] b43 ssb0:0: Direct firmware load for b43/ucode15.fw failed with error -2 [ 9.513063] b43 ssb0:0: Direct firmware load for b43-open/ucode15.fw failed with error -2 [ 9.513100] b43 ssb0:0: Direct firmware load for b43-open/ucode15.fw failed with error -2 [ 9.513104] b43-phy0 ERROR: Firmware file "b43/ucode15.fw" not found [ 9.513108] b43-phy0 ERROR: Firmware file "b43-open/ucode15.fw" not found [ 9.513111] 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.
