How to fix WiFi for Z83-4 devices on different Linux distributions.

1. Open terminal (Usually CTRL+ALT+T)

2. Type "sudo thunar /lib/firmware/brcm" then press "enter" (replace "thunar" with appropriate file manager name)

3. Provide requested password

4. Using the file manager that just opened with sudo permissions rename "brcmfmac43455-sdio.MINIX-NEO Z83-4.txt" to brcmfmac43455-sdio.txt"

5. Close file manager

6. Type "exit" into the terminal window to close it

7. Reboot

8. Enjoy your WiFi

PS. I couldn't do it with command line alone. Command line does not like uppercases or spaces in file names. I don't know. I'm new to linux. I performed this on a Z83-4 Plus running Ubuntu Studio.

Thank You It worked!!!!!!!!!!!!!

Hi Fernando86 !
During upgrade of Ubuntu to 22 on my new Z83-4A, I lost the wifi.
I tried your solution... but without success: Parameters > Network shows only LAN but no wifi.
Any idea ?
Thanks for helping a minix newbie ;-)

Hi Fernando86,
Thanks!
Works with Ubuntu 22.04.2 LTS server.
