Missing wifi driver (failed to load brcm/brcm43xx-0.fw)

[LorFioroni]

Hello everyone, I've just installed a terminal version of debian on my computer. During the installation I've used an ehternet cable to have internet, but now that I've installed everything I would like to connect it to my wifi too (as It was with windows before).
Doing

Code: Select all

sudo ifconfig wlp3s0b1 up

I get the following error:

Code: Select all

brcmsmac bcma0:1: firmware: failed to load brcm/brcm43xx-0.fw (-2) SIOCSIFFLAGS: No such file or directory

Searching on the internet I've found a lot of people with the same error, but I could not fix my error in any way.
I hope someone of you may help me,
thanks,
Lorenzo

it's probably the wl driver, or possibly https://wiki.debian.org/brcm80211

ID the device
https://wiki.debian.org/WiFi
https://wiki.debian.org/HowToIdentifyADevice/PCI

then check https://wiki.debian.org/wl
