There is no way to set UP wlan0 in debian after system update

Did you reboot? If not, do that, then post the output from

Code:

dmesg | grep b43

Here is what I get

Quote:

That's a good sign, no more firmware errors mentioned for the device.

Are you still getting the

Code:

 RTNETLINK answers: No such file or directory

error if you run

Code:

 ip link set wlan0 up

?

Yup. Still getting that kind of error.

That's about as far as I can take you. On my system, the output of the iw dev command for both a disconnected and a connected wireless card is as follows:

Code:

iw dev
phy#0
	Interface wlan1
		ifindex 4
		wdev 0x1
		addr xx:xx:xx:xx:xx:xx
		type managed
		txpower 0.00 dBm
phy#1
	Interface wlan0
		ifindex 3
		wdev 0x100000001
		addr xx:xx:xx:xx:xx:xx
		ssid SSID
		type managed
		txpower 200.00 dBm

You only mention half that information in your output, but it's good that it sees the device. And you mention it is seen with ip.

But as far as I can see, if the card is appearing in iw dev, and ip a, and the firmware is loaded, it makes no sense that setting the interface up fails.
