Not again?! Can't set up WEP key
 

Hi all:

just wondering anyone can help here, this linux thing is really trouble of the troubles.... :(

I previously set up wireless network without WEP key and it works fine. When I add WEP, it suddently not working. Okay here are what I did:

Before enable WEP I use:
iwconfig eth0 essid "abc"
ifconfig eth0 up
dhcpcd eth0
it works fine;

Now with WEP key "1a2bc" (hex) added, I just add one more line:

iwconfig eth0 essid "abc"
iwconfig eth0 key 1a2bc
ifconfig eth0 up
dhcpcd eth0

and it's not working! Did I miss anything? I searched iwconfig man page and didn't find anything left. Need help please!
