Wifi stops working inexplicably

[bigcfk]

Hi, I'm installing Ubuntu 16.04 (yes) on a 2011 MacBook Pro and am having trouble with the WiFi. It worked while I installed it, and it had no problems after I rebooted it. But then I performed an update, and now no networks are listed. When I run "nmcli device status" I get:

 device type state connection
 wlp2s0 wifi disconnected --
 enp3s0 ethernet unavailable --
 lo loopback unmanaged --

"nmcli general status" says there is no connectivity. I've set the REGDOMAIN to the correct country code. I've removed and reinstalled the Broadcom drivers and that didn't work. I tried installing 18.04 but it wouldn't boot after installing.

Can I downgrade network-manager? (I've read in one thread that this solved it, but I've read several solved threads that don't work for me )

Thanks for any help!

Thanks for the quick reply!

Here is the output: paste.ubuntu.com/p/4xRs43vpkG

I next followed the Broadcom steps, and purged then installed "bcmwl-kernel-source". But no change.
