Why is Wifi not working on my HP laptop? [duplicate]

This forum post seems to have helped most people facing this issue.

I have reproduced the necessary steps here for the sake of simplicity.

In the Additional Drivers application, check for any drivers pertaining to STA and disable them.

Open Terminal and enter the following command:

sudo apt-get remove b43-fwcutter broadcom-sta-common broadcom-sta-source firmware-b43-installer firmware-b43-lpphy-installer firmware-b43legacy-installer bcmwl-kernel-source

Now, enter the following commands:

echo "blacklist bcma" | sudo tee -a /etc/modprobe.d/blacklist.conf
echo "blacklist brcm80211" | sudo tee -a /etc/modprobe.d/blacklist.conf

Reboot Ubuntu.

Open Terminal again and enter the following command:

sudo apt-get install bcmwl-kernel-source broadcom-sta-common broadcom-sta-source firmware-b43-installer

After the package installation is complete, reboot.

Open Additional Drivers.

Enable the Broadcom STA driver.

Your Wifi should now be active and functional.

This seems to be a documented bug.
