about wireless card of thinkpad w500

[waterloo2005]

my wireless card can find my AP, but can not connect it . How to know if this is a hard problem or soft problem ? thanks

another computer can connect to the AP , so it is not my AP problem.

Assuming that your wireless interface is called wlan0, type

iwconfig

To find out. If it's anything else than wlan0, substitute the below wlan0 with your interface his name.

Does your AP use encryption? If yes, try to start wpa_supplicant like so:

wpa_supplicant -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -Dwext -B

Then do:

wpa_cli scan
wpa_cli scan_results

You should see your network in the list. If not, that might mean it's hidden. Then you need to manually add your network to wpa_supplicant.conf so that your wireless equipment can do a 'direct probe'.

If your AP does not use encryption, do this:

iwconfig wlan0 scan

Then your wireless should show up, if not hidden .

Good luck!
