ipw3945 + wpa2 hidden ssid = FAILURE [SOLVED]

Hello sirs,
I have an Intel wifi card 3945 with driver ipw3945.
Sometimes I can connect, but the most part of the time it is impossible to connect with Network Manager.
I've already tried with wicd, wifi radar, wpa_supplicant and nothing

My wifi is: WPA 2 Personal AES CCMP Hidden SSID (with broadcast ssid it has the same)

My config of wpa_supplicant.conf:

ctrl_interface=/var/run/wpa_supplicant


ctrl_interface_group=wheel

ap_scan=2

network={

ssid="MY SSID"

scan_ssid=0

key_mgmt=WPA-PSK

psk="PSK KEY generaetd with wpa_supplicant"

priority=1

}

When i run

wpa_supplicant -ieth1 -c/etc/wpa_supplicant.conf -Dwext

It outputs the following

Trying to associate with SSID '...'
Authentication with 00:00:00:00:00:00 timed out.

I have already tried:

iwconfig eth1 up
iwconfig eth1 essid MY-SSID ap MY-AP-MAC
wpa_supplicant -ieth1 -c/etc/wpa_supplicant.conf -Dwext

And happened the same.

Any idea?

What happens if you don't use network manager?

If I don't use networkmanager I can't connect. With Network Manager SOMETIMES I can connect, but rarely.
I will test this with wep and without encryption and watch what happens. Perhaps is a bug in ipw3945 driver.

I can only say I have had similar issues with rt2x00 drivers (and the legacy ones), and with the (stable!) ipw2200 drivers. You could think the beta status of iwlwifi drivers has something to do with it, but frankly I don't. Linux + hidden APs alltogether do not seem to work well together.

Re: ipw3945 + wpa2 hidden ssid = FAILURE [SOLVED]

So I need to wait a stable driver of iwlwifi?
I tested with ndiswrapper and same thing
Well, I will put the ssid with broadcasting and test it.

EDIT: I've putted it with broadcasting ON and I can connect.

Question: When ssid is broadcasting is not more vulnerable then when it is hidden? I use WPA2 PSK AES CCMP, does it is safe to have ssid broadcasting on it?

No more vulnerable. When ssid broadcasting is off, it's still possible to detect that a network exists, and there are ways of uncovering it's ssid.

You're running wpa2, you should be fine as long as you don't have an obvious dictionary word for your passkey.

No
It's a 16 characteres passkey with characters like % $ # :-P

Well, I will put problem solved in the topic title.
Thank you B for the hint of broadcasting ssid :-)
And thanks to others too, Open Source Community rox!

I "solved" it putting the ssid in broadcasting. But with hidden it fails

Several drivers have had problems with this. There was some discussion on this topic on the wireless-dev mailing list, and I think they have been fixed at least for iwl{3945,4965} and ralink.

Ok brain0, when it comes stable I will try and do a feedback in this topic.
