If i do 'iwlist eth1 scanning' I get 17 access points listed. All have in common that reported 'Quality' is at least 16 but 'Signal' level

Of course no connection neither with NetworkManager nor with traditional iwconfig/ifup is possible. NetworkManger even does not show me the access points.
Is the ipw2100 driver broken? Does anyone have this problem with other WLAN hardware?
With openSUSE-11.1 WLAN did work almost perfect. Starting witn openSUSE-11.2 it was no longer possible to associate to an AP while NetworkManager was still showing them all.
Hi Stefan,
I use an IBM Thinkpad R50 with Centrino chipset and have the same problem. My WLAN card worked fine with 11.2, and refuses to connect with 11.3. Signal is available (4 APs are shown), but no connection. At boot time, I get the warning that the hardware does not support WPA2 and therefore the connection can't be stablished. Strange that the hardware was able to cope with WPA2 in openSUSE 11.2. Meanwhile I found out that iwlist reporting zero signal level and link quality greater then zero is just wrong but common and not relevant. The ipw2100 driver is able to connect despite that.
It turned out that in my case there is a confusion regarding RFKILL state, see https://bugzilla.kernel.org/show_bug.cgi?id=14098 (start at comment #14) Right now it looks to mee ike that mostly (or maybe exclusively) dell notebooks are affected. In fact there was an rfkill suspen/resume related patch in thinkpad-acpi in kernel 2.6.31.9, see http://lwn.net/Articles/367445 thus this should be fixed. Is your driver ipw2200 or something else? If you see an error 132 when wpa_supplicant is executed then you have the same issue then me (in my case this does not get logged to /var/log/messages). In this case the rfkill command (package rfkill) will help, see https://bugzilla.novell.com/show_bug.cgi?id=530264 Otherwise http://en.opensuse.org/SDB:Tracking_down_wireless_problems#How_to_set_up_a_c... will be helpful to track down issues in general.
