no wifi with kernel 3.15.0-1.3 when using bcm 4309

[volker kempter]

no wifi with kernel 3.15.0-1.3 when using bcm 4309:

this is when using kernel 3.15.0-1.3 in lubuntu-14.04 trusty and bcm 4309 (driver b43).
This problem does not occur when using kernel 3.15.0-1.3 with bcm 4312 (driver bcm-kernelsource) (neither for lubuntu 14.04 nor 14.10).

This problem does also not occur when using instead kernel 3.14 in lubuntu-14.04 or 14.10 (i.e. wifi works with bcm 4309 and 4312).

I suppose it is not a problem with the kernel 3.15, but the driver b43 may need some adaption.

wifi problem persists with kernel 3.15.0-1.4:

no wifi with broadcom bcm 4309 (driver b43-fwcutter). This is for lubuntu-14.04 trusty.
Connection via cable works.

On the other hand, wifi is okay when using kernels <3.15 (checked with 3.13 and 3.14).

volker kempter, thank you for taking the time to report this bug and trying to help make Ubuntu better. However, the mainline kernel 3.15-rc5 is not software package provided by the official Ubuntu repositories. As per https://wiki.ubuntu.com/Kernel/MainlineBuilds#Kernel.2BAC8-FAQ.2BAC8-DebuggingMainlineBuildsSupport.Does_the_kernel_team_support_the_mainline_kernel_builds.3F :
>"The mainline kernels builds are produced for debugging purposes and therefore come with no support. Use them at your own risk."

Because of this the Ubuntu project can not support or fix your particular bug. Please report this bug to the provider of the software package -> www.kernel.org . Thanks!

I had (have) the same issue.

but, looking around the internet I found that "modprobe b43" solve this issue.
(I stopped using "modprobe wl")

[penalvch (penalvch)]

nadavkav, thank you for your comment. So your hardware and problem may be tracked, could you please file a new report with Ubuntu by executing the following in a terminal while booted into the default Ubuntu kernel (not a mainline one) via:
ubuntu-bug linux
