A strange problem with my wireless card

Question

my box is lenovo ideapad y550, the wireless card is intel 5100. After i update to kernel 2.6.32, there is a strange problem occored.
i configure my wireless at /etc/rc.conf like this:
MODULES=(...... iwlagn ......)
wlan_wlan0="wlan0 essid xxxx key s:xxxxxxxxxxxxx
wlan0="dhcp"
INTERFACES=(wlan0)
DAEMONS=(......network......)
it works well at 2.6.31
but at 2.6.32, i find during the archlinux start, it tell me that "dhcpcd time out"
so i remove network from DAEMONS  and just load the wireless card's driver module, then i configure my wireless at the bash.
meanwhile, i find another strange appearance
when i use:
   ifconfig wlan0 up
   iwconfig wlan0 essid xxxx key s:xxxxxxxxxxxxx
   dhcpcd wlan0
it tell me "dhcpcd time out"
and then dhcpcd wlan0 again ,it works.
while i use:
   iwconfig wlan0 essid xxxx key s:xxxxxxxxxxxxx
   ifconfig wlan0 up
   dhcpcd wlan0
it works well.
i just put iwconfig before ifconfig, it works~ 囧!
now i have to remove network from DAEMONS at /etc/rc.conf and put the commands in the /etc/rc.local
anyone have ideas?why?
thanx very much and sorry for my english. english is not my mother language. :-)

Notes on trying out netcfg:
- install netcfg: pacman -S netcfg
- set up a profile file in /etc/networks.d (copy a file from /etc/networks.d/examples and edit it)
- add the name of the profile file to NETWORKS=() in /etc/rc.conf
- add '@net-profiles' to DAEMONS=() in /etc/rc.conf (put it after 'network',  prefixed with '@' so you don't have to wait for the network just to log in)
- remove the name of your interface that you want netcfg to set up from INTERFACES=() in /etc/rc.conf (so it doesn't try to set it up twice)
- also turn off whatever other network configuration daemon, like wicd, you might have been using.
