Wireless down and can't connect

Question

I am new and learning some things like wifi hacking (for educational purposes) and after I ran this command on terminal:

sudo airmon-ng start wlan0 up

I disconnected on the internet and can't see the wireless networks list. How do I connect to the internet?

Answer 1

Finally it worked, I ran these commands:

sudo ifconfig wlan0 down
sudo iwconfig wlan0 mode monitor
sudo ifconfig wlan0 up

The first time, it didn't work. I think I rebooted my pc then tried it again and then it worked.
