Package: firmware-brcm80211
Version: 0.43+rpi5
Severity: important

Dear Maintainer,

After upgrading my RPi3 from 'jessie' to the actual stable, the wlan
module could not initialize anymore.

Well first I filed a bug agains the BRCM driver in kernel 4.9.35-v7+ as
I belived this was a problem of said driver with the actual firmware.

As this problem massively bothered me, I went on an installed a fresh
'actual' Raspbian on a separate SD card and bootet. WLAN works fine, so
not a hardware issue.

But I noted that Raspbian uses 'jessie' as release tag and changed this
to stable, as I want to stay with stable.

Did a dist-upgrade.

And again, the WLAN device was gone.

I investigated further into the problem and noticed, the MD5 sums of
the files in /lib/firmware/brcm had changed.

I did a downgrade to firmware-brcm80211=0.43+rpi5 and the WLAN device
is back.

My search on google, revealed that a lot of other RPi 3 users run into
that problem and apparently I am the first to figure out the cause.

So I suggest that the firmware-brcm80211=20161130-3 in the raspbian
repository should be checked and made sure the correct firmware version
for the 'stable' kernel ins included.
