[Solved] wireless card can't find networks

[HanSoli]

Hello everyone,
Yesterday I installed debian 12 on my old macbook pro (2009)
During the installation I received the message "Missing files are: b43-open/ucode16_mimo.fw e b43/ucode16_mimo.fw"
Anyway, I continue with the installation and after that, I couldn't see the wifi toggle so I connected the pc with ethernet and I follow this guide to install broadcom firmware: https://wiki.debian.org/wl

After the installation of the drivers the wifi toggle appeared but the problem is that wifi can't find networks (where I live there are at least 10 wifi-networks)
If it's useful the command iwconfig returns:

Code: Select all

lo        no wireless extensions.

enp3s0    no wireless extensions.

wlp2s0    IEEE 802.11  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=23 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off

Now I don't know what to do. Maybe I installed the wrong drivers?
Can anyone help?

I'm a very beginner, so be patient...
Sorry for the english.
Thank you in advance.

I have not had a Broadcom in many years, but my money would be on this:

Code: Select all

$ sudo apt install firmware-b43-installer

or (if you made a root account during install):

Code: Select all

$ su -

Enter root password

Then finally:

Code: Select all

# apt install firmware-b43-installer

And reboot.

ok, I ran the code and reboot.
After the reboot the wifi didn't work for about 2 hours.
After that time, now the wifi works perfectly.

Thank you Hallvor!!!

I'm glad it worked. Enjoy Debian!
