Hi @faccig,
Your bug seems duplicate of Bug #1910555. Take a look there for workaround till Canonical fix gets released. 😉
Hope this helps.

Status changed to 'Confirmed' because the bug affects multiple users.

[Carlos Tavares Jr (carlosmtavaresjr)]

Confirmed on my HP Laptop as my wifi isn't being detected after this upgrade. Whats weird is my wifi switch on the keyboard is now the airplane mode and causing issues. Currently tethering off my phone to write this message. Please fix as this bricked my wifi card built into this HP 8640P workbook.

@Rakhmanov's solution worked for me a week ago, however, latest Ubuntu kernel update has again brought back the problem. No wifi now. Tried searching for updated broadcom STA drivers with same filenames i.e. bcmwl etc. but to no avail. Please guide / help.
