Answer 1

From: Turn Bluetooth on or off

You can turn Bluetooth on to connect to other Bluetooth devices, or turn it off to conserve power. To turn Bluetooth on:

• Open the Activities overview and start typing Bluetooth.

• Click on Bluetooth to open the panel.

• Set the switch at the top to ON.

Many laptop computers have a hardware switch or key combination to turn Bluetooth on and off. Look for a switch on your computer or a key on your keyboard. The keyboard key is often accessed with the help of the Fn key.

From this answer:

• Ubuntu 18.04 wireless connections visible but won't connect BCM43602

You can try:

sudo apt-get purge bcmwl-kernel-source
sudo apt update
sudo update-pciids
sudo apt install firmware-b43-installer
sudo reboot #note that this will restart your computer
sudo iwconfig wlp2s0 txpower 10dBm
