Using CentOS 6 I cannot get my WiFi interface to configure over DHCP. Here is my ifcfg-wlan0:

This does not work (although it is correct):

DEVICE=wlan0
BOOTPROTO=dhcp
ONBOOT=yes
HWADDR=xx:xx:xx:xx:xx:xx
TYPE=Wireless

This works:

DEVICE=wlan0
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.168.0.253
NETMASK=255.255.255.0
DNS1=192.168.0.99
GATEWAY=192.168.0.99
HWADDR=xx:xx:xx:xx:xx:xx
TYPE=Wireless

I don't want a static IP address, I want a DHCP assigned address.

Update: Both of the above configs are correct.

Please don't downvote, this really didn't work for me. It must be a bug in CentOS or my wireless driver. See my answer for details.
