I recently purchased an HP Notebook 17-y020ca and installed XUbuntu 16.04. This notebook has a Broadcom Corporation BCM43142 wireless card.
This wireless card was not originally detected (but the ethernet card worked fine), and I followed the instructions at:
Is it possible to use Broadcom BCM43142 wifi in Ubuntu 16.04?
and now the card appears to be generally detected, and "Enable WiFi" is given as an active (non-greyed-out) option in my Networking menu in XFCE.
When I DO click "Enable WiFi" this menu will often change the status to indicate that it is enabled via a checkmark next to "Enable WiFi". However, when this happens, one of two things happen further up in the menu. Either it says:
"Wi-Fi is disabled"
or
"Wi-Fi not ready"
I ran the wireless-info.bash script and include below.
I would be truly grateful for any suggestions that anyone could give. I much appreciate your consideration!
Sincerely, Nathaniel Osgood
