Mike,

I just noticed that the linux-wireless list was not in the Cc list - I added it. 
I also changed the subject to help catch the attention of the Broadcom 
maintainers. I am definitely not one of them.

Your device is a BCM4345, which uses the brcmfmac driver. The dmesg output that 
you posted shows the firmware loading, but nothing happens beyond that. This is 
the point where I would expect the user-space code such as NetworkManager to 
take over. What code do you use to control wifi? Did that change when your 
kernel was updated?

Larry,

I'm using NetworkManager but I also tried Wicked with the same results.

NetworkManager tries to connect but fails.

Why was that not logged in your dmesg output?

Broadcom devs: Is there something in kernels 6.2.2 or later that break connections?

Hi,

I think I may be hitting the same bug. I have this device:

02:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries 
BCM4350 802.11ac Wireless Network Adapter [14e4:43a3] (rev 05)

This is a 2017 MacBookPro14,1.

NetworkManager fails to connect when booting Linux v6.2.5, but seems to 
have no problems with v6.2.1.

Let me know if you need more information.
