iwlwifi is up but can not detect wireless network


i check dmesg it shows

Code:
Intel(R) Wireless WiFi Link AGN driver for Linux, in-tree:
Copyright(c) 2003-2011 Intel Corporation
iwlwifi 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17

iwlwifi 0000:03:00.0: loaded firmware version 9.221.4.1 build 25532
Registered led device: phy0-led
and `lsmod | grep iwl` gives
Code:
iwlwifi               146774  0 
mac80211              171359  1 iwlwifi
cfg80211              117454  2 iwlwifi,mac80211
It looks working normal. However, when launching e.g. wicd-client
the gui dones't show any usable network. And the led light is not urned on.

Is there any other place I can check what might go wrong?

Thanks.

Open a konsole, run the commands as root, ifconfig and iwconfig and post the results.

Do you know the 'essid' of the wireless access you are trying to access?

What distro? Do you have any tools installed like Netowrk Manager or WICD?

You can also run the command 'iwlist scan' in a konsole to look for wireless access points.

Any chance the access point is hidden? ie they do not broadcast their essid?

Eventually I know what goes wrong there. I am stupid that I forgot long time ago the hardware switch were turned off, and I completely forget it. (just read [1] that reminds me that hardware switch were turned off.)

The led light is on again now, and looks like I can see networks when launching wicd-client.

Thanks for help. Much appreciate it.
