[Bug 38766] Re: [bcm43xx] Wireless not properly detected.

[Celso Pinto]

A couple of lines on the dmesg output file look rather suspicious:

[   29.868597] bcm43xx: Error: Microcode "bcm43xx_microcode5.fw" not available or load failed.
[   29.935748] bcm43xx: Error: Microcode "bcm43xx_microcode5.fw" not available or load failed.

A web search led me to this page, which contains a workaround for your problem:
