Here is my network interface file from /etc/network/interfaces

can someone tell me what is wrong with it? I'm trying to get my wireless network card come up automatically. Right now I have to wlan config and pump multiple times to get it to come up.

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
# automatically added when upgrading
auto lo
iface lo inet loopback

iface eth2 inet dhcp
wireless-essid xxxxxxx
wireless-mode managed
wireless-channel 6
wireless-key xxxxxxxxxx key restricted


Thanks
