http://bugzilla.novell.com/show_bug.cgi?id=556665#c0 Summary: NetworkManager repeatedly drops connection to WPA protected wireless network Classification: openSUSE Product: openSUSE 11.2 Version: Final Platform: x86 OS/Version: openSUSE 11.2 Status: NEW Severity: Normal Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: b.m.kast@gmail.com QAContact: qa@suse.de Found By: --- Blocker: --- Created an attachment (id=328292) --> (http://bugzilla.novell.com/attachment.cgi?id=328292) A frament of /var/log/messages User-Agent: Mozilla/5.0 (X11; U; Linux i686; ru; rv:1.9.1.5) Gecko/20091103 SUSE/3.5.5-2.2 Firefox/3.5.5 The wireless network adapter (Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)) authenticates with the access point (D-Link DWL-G700AP, configured for WPA1-PSK) and tries hard for half a minute to associate. The association succeeds at last, but drops in approximately 36 seconds, then the process repeats from the beginning. NetworkManager asks for a new key once during each cycle. Addidionally, the NM state displayed by a client may NOT correspond to actual connection state. The behaviour does not depend on the NetworkManager client (tried with KNetworkManager and GNOME's nm-applet). If using any other network management method (tried Wicd and ifup), the same wireless network connects quickly and works pretty stable. Packages installed: wpa_supplicant-0.6.9-4.3.i586 NetworkManager-0.7.1_git20090811-4.2.i586 Logs are attached. Reproducible: Always Steps to Reproduce: 1. Unplug any network devices except Wi-Fi 2. Find a WPA-protected wireless network 3. Create a connection to it using NetworkManager 4. Wait half a minute (a password is asked after that) 5. Enter the password 6. Wait some extra time (the connection is indicated up, but may be actually down) 7. Wait extra half a minute (the connection goes down as the client indicates) 8. Go to step 4 :) Actual Results: The NM applet shows network connection progress for some time, then asks for a password (again). After a while the applet shows that the connection is up, but it goes down again after half a minute Expected Results: The wireless connection must be kept up for a long time (until something goes down on the other end, or the user asks for disconnection) -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Vlad, any idea what is happening to cause wpa_supplicant to disconnect?

As stated in the description ifup works. This means driver and wpa_supplicant is ok. Comparing wpa_supplicant.log with/without NM could show the difference. Switch the wpa_supplicant debugging and timestamping with the -dddt option. Guide is here [1]. The wpa-supplicant timestamps can be converted [2].
