Now you know that your adapter is being recognised you can now go on to getting your network adapter set up. There are many ways of doing this, like using the wpa_suppicant file.

This will force the network adapter to get an ip from your networks DHCP server. If this runs without any errors, type in the command ifconfig. You should then see an ip address assigned to eth0 which is the ip address that you connected to the pi, and also an ip assigned to the wlan0;
