ifcfc-wlan0 config file problem

Hi. This is the minor problem I am having after I successfully installed the 
driver for my Linksys wireless adaptor. Based on what I learned from the 
mailing archive, I created a file called "ifcfg-wlan0" under directory 
"/etc/sysconfig/network-scripts" with the following configurations:

DEVICE=wlan0
BOOTPROTO=dhcp
ONBOOT=yes
USERCTL=yes
TYPE=Wireless
ESSID=faosjtu
CHANNEL=6
MODE=Managed
RATE=Auto
KEY=B38D-D7B4-EF66-7CA1-0820-E2D6-71

I also added 2 more lines to file "network" under directory 
"/etc/sysconfig". So the entire file reads as:

NETWORKING=yes
HOSTNAME=localhost.localdomain
GATEWAY=192.168.1.1
GATEWAYDEV=wlan0

("GATEWAYDEV" may not be necessary, but I learned from the web somewhere 
that in some cases it is necessary. Since it does not hurt, I added this 
line as well.)

However, during the linux boot up process, I got the following error message 
"Determining ip information for wlan0 ... failed".

When I check the configuration with "iwconfig wlan0", I noticed that my 
configurations in the ifcfg-wlan0 file was not picked up. Essid was wrong, 
key was not specified, mode was "ad-hoc" instead of "Managed", channel was 
"11" instead of "6" ...

But once I manually configured the interface with "iwconfig wlan0 mode 
Managed channel 6 essid faosjtu key ... restricted" command and then run 
"service network start", I got everything working.

I found a similar post on the mailing archive (also with red hat linux 9.0), 
  the latest post reports that all the configurations are picked up but the 
one for key. So the problem is at least partially solved. But no solution ( 
nor partial solution ) is provided in the post. So can someone offer some 
insight on this? Thanks in advance.

Luke
