I recently installed Juno to my laptop and i found that WIFI is not working anymore. Previously, I had Loki installed, and WIFI was working fine. Because wifi is not working, I cannot installed any further update (driver, etc).

My laptop is HP Envy 15".

Anyone know a solution for this?

I put my findings here, just in case anybody run into the same problem.

HP 15" Envy uses broadcom wireless driver, you can find this out by invoking the following command

 lspci -vnn | grep Network

This will get a response like this.

01:00.0 Network controller [0280]: Broadcom Limited BCM43142 802.11b/g/n [14e4:4365] (rev 01)

Answer on for the this askubuntu.com question explained the things that needs to be done quite extensively.
