This link has your answer!

Adding it to /etc/network/interfaces /etc/network/interfaces is the file where your network interfaces are defined, eth0 being the standard wired interface. To make the wireless network come up when you start your computer put # in front of 'auto eth0' (to stop it automatically starting) and add something like the following lines.

sudo nano -w /etc/network/interfaces

auto wlan0 iface wlan0 inet dhcp wireless-essid MYNETWOTK wireless-key FEFEFEFEFE wireless-channel 11 wireless-mode managed

Thank you for your swift reply. I wanted both the wireless and wired networks to be active at the same time.How do you that without commenting the auto eth0
