Changing adapter back to manged mode

Solution 1:

You should execute:

sudo ifconfig wlan0 up

And it should come back to life.

Just to give you a little explanation: the output of the command ifconfig only shows the interfaces that are up. For example, you'll notice that your eth0 interface is up:

eth0       Link encap:Ethernet  HWaddr 00:24:21:6f:84:69  
           inet addr:10.100.1.41  Bcast:10.100.255.255  Mask:255.255.0.0
           inet6 addr: fe80::224:21ff:fe6f:8469/64 Scope:Link
           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

Your ifconfig output does not have wlan0 listed, meaning that it has been turned off. If you do ifconfig -a, you should see all interfaces (up or down), and you'll notice that wlan0 won't have UP displayed. And all of this makes complete sense because you switched off your WiFi card when you did ifconfig wlan0 down. So ifconfig wlan0 up should bring it back online. If it doesn't work straight away, do a sudo service network-manager restart.
