(Solved)ipw2100 cannot scan wifi access point

I installed archlinux on my centrino notebook which contains a build in ipw2100 wireless network adapter. I followed the instruction from http://wiki.archlinux.org/index.php/Wireless_Setup and got the following result:

bash-3.2# ifconfig -a
eth0      Link encap:Ethernet  HWaddr 00:03:25:09:50:B2 
          inet addr:192.168.1.101  Bcast:192.168.1.255  Mask:255.255.255.0

          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

but when I tried to scan my linksys wrt54g router with command iwlist but failled to scan:

bash-3.2# iwlist eth1 scan
eth1      No scan results

I also installed the archassistant tool but can't scan either.
The ipw2100 driver seemed installed well:
bash-3.2# dmesg | grep ipw2100
ipw2100: Intel(R) PRO/Wireless 2100 Network Driver, git-1.2.2
ipw2100: Copyright(c) 2003-2006 Intel Corporation
ipw2100: Detected Intel PRO/Wireless 2100 Network Connection
firmware: requesting ipw2100-1.3.fw

My wireless network is not hiddened ssid.
Can anyone help me to bring my wifi work?
Regards.
