Since I upgraded from Linux 2.6.24, NetworkManager cannot associate my
Intel wireless card, handled by the ipw2200 driver, with my AP, which
has a hidden SSID.
NetworkManager thinks that wpa_supplicant should be able to scan for
specific hidden SSIDs if the underlying driver advertises
IW_SCAN_CAPA_ESSID, which ipw2200 does since 2.6.25. However, this
doesn't work.
I have confirmed that NetworkManager is interpreting this capability
flag correctly and checked that wpa_supplicant has the patch that I
was referred to - see the thread on linux-wireless
<http://thread.gmane.org/gmane.linux.kernel.wireless.general/15560>.
Therefore I believe the driver is at fault.
This should be fixable by removing the capability flag:
