DHCP fails at boot

Hi,
I'm new to Arch and I'm having problems with the dhcpcd deamon when the box boots.
It seems the to connect to router ok but I cannot access the internet, the only way around this is to rerun the dhcpcd deamon the everything works as it should.

iwconfig & ifconfig after boot:

[root@archlinux weaner]# iwconfig

Also, here's the /etc/network-profiles/home settings that I'm using:

#
# Network Profile
#

DESCRIPTION="Default Network Profile"

# Network Settings
INTERFACE=wlan0
HOSTNAME=archlinux

# Interface Settings (use IFOPTS="dhcp" for DHCP)
IFOPTS="dhcp"
GATEWAY=192.168.0.1

# DNS Settings (optional)
DOMAIN=localdomain
DNS1=192.168.0.1
DNS2=

# Wireless Settings (optional)
ESSID=deansnet
KEY=************************************
IWOPTS="mode managed essid $ESSID channel 11 key open $KEY"

WIFI_INTERFACE=wlan0   # use this if you have a special wireless interface
                        # that is linked to the real $INTERFACE
#IFOPTS="dhcp"
#WIFI_WAIT=3            # seconds to wait for the wireless card to
                        # associate before bringing the interface up

#USEWPA="yes"           # start wpa_supplicant with the profile
#WPAOPTS=""             # use "" for normal operation or specify additional
                        # options (eg, "-D ipw")
                        # see /etc/wpa_supplicant.conf for configuration

Can anyone give me any pointers?
Thanks in advance,

Re: DHCP fails at boot

You DNS is incorrectly set.  Your net is 192.168.1.* and you have your DNS set to 192.168.0.*
