Connect to Wi-Fi on MacBook Pro with Ubuntu 22 and Broadcom wireless adapter BCM43602?

pg flag

This question is very similar to Ubuntu 18.04 wireless connections visible but won't connect BCM43602 however the solution (the same as below) does not work for me.

The problem: I can see all wireless networks but when I try to connect to one with a valid password, it does not connect and I keep receiving the authentication required prompt.

The steps I have tried to solve the problem (note, I had no errors for these commands):

sudo apt purge bcwl-kernel-source
sudo apt update
update-pciids
sudo apt install firmware-b43-installer linux-firmware
sudo reboot

(These steps come from Installing Broadcom Wireless Drivers)

Then once rebooted, I ran sudo iwconfig wlp2s0 txpower 20dBm.

The result: the problem still persists.

Can someone provide some assitance?

I include below the output from some commands which may be useful:

lspci -vvnn | grep -A 9 Network

FYI, this is a MacBook Pro 2016 13 inch

PS, I also found Macbook pro 2017 15' won't connect to WIFI which is similar but there is no answer.

Hi this is not the answer yet I'm sorry. I would post it inside a comment but it is too limited for this case. I have a MacBook Pro Mid 2012 with Ubuntu 22.04.1. The Wifi is working but sometimes it fails. If I restart the system Wifi works again.

Here is the output inside the terminal for one command that @Jono also posted above:

lspci -vvnn | grep -A 9 Network

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
