I saw this bug when I upgraded my laptop earlier today.  Unfortunately, my desktop was upgraded a day or two ago and I have verified the bug to be valid.  I'm unable to connect at all via a wireless connection.  Based on my setup and some of the bug report submissions, this may only affect Broadcom wireless cards.

and the reason was: system was not fully dist-upgraded

How did you come up with that conclusion?

just a follow up. A RTL8188eus USB WIFI dongle stopped working as well after du, an internal intel golan still works just fine.

Hello Krunchtime,

I've read the message #60  where the original reporter had to admit:

Interesting. I was using 1.4.2-3. After trying this workaround/fix I updated
to 1.4.4-1 which is what I'm currently using.

In fact network-manager 1.4.4-1 was released to unstable one hour before wpasupplicant 2.6-2.

Hello mld,

as mentioned above: "new mac address randomization breaks WiFi with various drivers".
see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=835822

It seems network-manager still doesn't play nicely with all of the wifi drivers.
You can try adding
[device]
wifi.scan-rand-mac-address=no

to your /etc/NetworkManager/NetworkManager.conf

greetings
musca

[yes, Krunchtime, it's a bug in network-manager, not wpasupplicant.]

Hmmm...re-reading the OP in that bug report thread, it appears that the OP is mixing testing and unstable.  I'm surprised the Debian folks even entertained the initial report.

Is the above fix a temporary fix?  In other words, is the above setting something that may cause issues with particular WiFi drivers in the future?  Also, I was using the latest version of network-manager before the wpasupplicant upgrade and was not experiencing WiFi issues.

Modifying /etc/NetworkManager/NetworkManager.conf didn't work for me.  I've resorted to using ethernet.  I'm going to attempt to downgrade wpasupplicant until this gets ironed out.

My network card:  Broadcom Limited BCM4352

This is twice now that WiFi has been broken under Unstable on my desktop.   >:(

Edit:  I wonder if the upgrade to the broadcom-sta-dkms package might be the real issue.  It was upgraded the same day (12/20/2016) as wpasupplicant.

No recent open bug reports for the broadcom-sta-dkms package.

uhm, things get more complicated the deeper we look into this case.

Yes, it's a temporary work-around. You are unhiding your mac address.

Maybe worth a bugreport to debian BTS, to help testing the corner cases with your hardware.

You are unhiding your mac address.  Thanks, that's definitely something one should know.

Downgrading to wpasupplicant v2.5-2+v2.4-3+b1 resolved the WiFi issue on my desktop.

100% the same on my Lenovo Notebook

Also a BCM4352 WIFI adapter and only downgrading wpasupplicant to wpasupplicant v2.5-2+v2.4-3+b1 cured the problem

Creating the configuration for Network manager not helps
