Dan,
   here is another example, SSID Broadcast disabled on a home network.
Using wpa_supplicant alone I can connect(less than 5 seconds).

Using network manager I cannot. Note in both examples I have preset theSSID.

I am using NetworkManager 0.6.4 and have tried wpa_supplicant 0.4.8 & 0.5.7

Dan,
are there any plans for Network Manager to handle hidden essid's?
i.e. using wpa_supplicant I can connect with the following config.

ctrl_interface=/var/run/wpa_supplicant
eapol_version=1
network={
                ssid="MBI"
                scan_ssid=1
                eap=TLS
                key_mgmt=IEEE8021X
                pairwise=TKIP
                group=WEP104
                identity="traxtopel mbi com"
                ca_cert="/etc/eap/cacert.pem"
                client_cert="etc/eap/key.pem"
                private_key="/etc/eap/key.pem"
                private_key_passwd="whodareswins"
                eapol_flags=3
}

With networkmanager it never connects(the only way I have ever managed
to connect was to quickly do a iwconfig eth0 essid MBI and then fingers
crossed it worked once).

<snip>

I don't think the issue is a hidden SSID, I think the problem is using
EAP with WEP which I don't /think/ NetworkManager supports at this
time.  Dan, correct me if I am wrong.


Ah, you're right.  This is the "compat" mode that allows WEP clients to
continue to work with WPA base stations; since WEP clients don't know
anything about pairwise keys they can work as normal, but WPA-capable
clients can use TKIP/CCMP for all STA<->AP communication.

That's likely the problem, yes.

Dan
