It can be number of issues, driver, wpa_supplicant , NM, ...
Are you able to connect just with wpa_supplicant?

To debug further, please grab the following info:
1) nm-tool output
2) NetworkManager logs (/var/log/messages, /var/log/syslog, ...)
3) wpa_supplicant log (/var/log/wpa_supplicant.log, ...)
