12.2 Get started with WLAN

Now that we have all the pieces we need installed, it is time to check the
functionality and get things working.

12.2.1 The manual way

First we do it manually, to make sure we get the results and feedback that we
expect. This is to verify the functionality and simplify troubleshooting, if needed.
7. The WLAN interface should show up:
# iwconfig wlan0

8. Turn on the WLAN chip and bring up the interface:
# ip link set wlan0 up
9. OK, now it is time to find out what's in the air:
