How to install Broadcom bcm43602 Drivers on Ubuntu Linux

linux-ubuntu-install-wifi-drivers

sudo apt-get purge bcmwl-kernel-source
sudo apt update
sudo update-pciids
sudo apt install firmware-b43-installer
sudo reboot #note that this will restart your computer
sudo iwconfig wlp3s0 txpower 10dBm
#sudo iwconfig wlp2s0 txpower 10dBm

Thank you sir!
Just installed Ubuntu 22.04.1 LTS on my MacBook Pro 2016 13 inch and WiFi was not working.
I followed your steps as follows and WiFi now works:

sudo apt-get purge bcmwl-kernel-source
sudo apt update
sudo update-pciids
sudo apt install firmware-b43-installer
sudo reboot #note that this will restart your computer
sudo iwconfig wlp2s0 txpower 10dBm

FYI, the network controller is:
Broadcom Inc. and subsidiaries BCM43602 802.11ac Wireless LAN SoC [14e4:43ba] (rev 02)

Works great except I have to enter the last line every time I reboot. Any suggestions?
Thanks!

I am sorry I do not understand this reply. My wifi works in Ubuntu 22.04 but it will not work after a reboot. I have to paste
sudo iwconfig wlp2s0 txpower 10dBm
in a terminal on each reboot. Is there a remedy for this?
I do not see a file "wlp2so" in my files, and I would not know where to drag and drop it to even if I did see one.
Sorry If this is a silly question but I am lost.
Thanks

@satellite73 same for me -- I have to run the command sudo iwconfig wlp2s0 txpower 10dBm after each reboot.
I have not yet found a solution.

@jonpontet I am going to try this

to see if it will automatically run the command on reboot, which does not really address the problem, but will save some time

@jonpontet the above worked for me. In step #4 and #8 you must replace "xed" by "gedit" . I replaced "5" by "10" in step #5. Hope it works for you.

I got the same procedure to work for Kali Linux 2023.3 on a late 2013 MBP. The only difference is the adapter designation in Kali is simply wlan0. However, the procedure is solid and worked on the first attempt. Thanks for posting this!

Thanks, this worked great!
