The problem is that the card never finds the ap. Running wpa_supplicant directly shows "Got scan results xxx bytes" (can't remeber the exact message). While with ipw3945d + ieee80211 it works fine. (NetworkManager does not connect either see http://bugzilla.gnome.org/show_bug.cgi?id=464215 ). I haven't tryed the suggestion there yet because I am not near the network right now.

Fedora 7 kernels are a little behind (1-2 weeks behind wireless-2.6) ATM, so it might be best to handle this at bugzilla.kernel.org. F7 _does_ have the kernel patch to probe for hidden SSIDs when associating. What I've found with that patch is that manually invoking the wireless tools yields satisfactory results, but that NM (which afaik relies on wpa_supplicant) still tends to have problems. My hunch is that wpa_supplicant (at least how NM configures it) is doing something "too smart", but I really don't know. Do you have control over the AP? If so, can you temporarily try using static WEP or an open configuration so that you can test using iwconfig? Thanks, John -- John W.

However, this doesn't work often because drivers are inconsistent about this. The way it _should_ work is that if scan_ssid = 1 for a network, wpa_supplicant should ask that the driver scan the specific ssid using IW_SCAN_THIS_ESSID. The card would then issue specific SSID scan requests on each channel during the scan, and hopefully find the AP in question. Unfortunately, most drivers don't support IW_SCAN_THIS_ESSID. So the best we can do is set AP_SCAN=2, let wpa_supplicant blow all the settings to the card, and just _hope_ that the card/driver are smart enough to find the hidden SSID on their own and associate. Which is less often than we'd hope. Dan > Do you have control over the AP?

Yeah, pretty much; but each driver/firmware may handle hidden ssids slightly differently. mac80211 should bring some sanity to this area, but I wouldn't discount variation between even mac80211 based drivers.

Scanning in iwl driver is always initiated by the driver unlike ipw2X. 3. CCX is closed standard by Cisco and we are not eligible to open it. Talk to Cisco Tomas On 10/10/07, John W.
