Does your laptop/netbook have a WIFI on/off switch?
If you are on a wired connection, post "inxi -Fxzd" from your terminal (copy & past).

Or an Fn & F key combo to turn wifi on? It may look like a radio tower or airplane.

Click the connection icon lower right tray, then click 'Enable Wi-Fi'. It should have a check mark on left.
You might also go to Menu, Driver Manager & see if there is a wi-fi driver there you can enable.

Try #10 on that site since you seem to have Realtek RTL8821CE.
