WLAN-Probleme nach Update auf 9.510-5 - "WPA IE from (Re)AssocReq did not match with msg 2/4" - STA WPA failure

StefanB�nneken
 
Hallo zusammen,
 
nach dem Update auf 9.510-5 bei einem meiner Kunden haben wir starke Probleme mit der Stabilität des WLANs.
Aufbau: 11 AP55C - WPA2 Enterprise - (aktuell) 2,4Ghz
 
Ohne (bisher) erkennbares Muster werden die Clients mehrmals pro Stunde abgemeldet, bzw. versuchen sich an einem anderen AP anzumelden, was dann aber fehlschlägt. Teilweise wird die Verbindung nach einigen Sekunden / Minuten wieder automatisch neu aufgebaut, im extremsten Fall ist ein Neustart des betroffenen AP (insgesamt 11 im Einsatz) notwendig.
 
Zum Zeitpunkt der Verbindungsprobleme lassen sich folgende Einträge mehrfach im Log finden:
 
/var/log/wireless.log:2018:09:03-10:55:10 A4004712113XXXX hostapd: wlan1: STA ac:2b:6e:XX:XX:XX WPA: WPA IE from (Re)AssocReq did not match with msg 2/4
/var/log/wireless.log:2018:09:03-10:55:10 A4004712113XXXX awelogger[605]: id="4105" severity="info" sys="System" sub="WiFi" name="STA WPA failure" ssid="SSID" ssid_id="WLAN1.0" bssid="00:1a:8c:XX:XX:XX" sta="ac:2b:6e:XX:XX:XX" reason_code="2"
 
Der Fehler "STA WPA failure - reason_code="2"" sollte laut Changelog durch 9.510-5 behoben worden sein.
 
Wir haben bereits folgende Maßnahmen unternommen:
 
- Neustart der SOPHOS UTM SG
- mehrfacher Neustart aller APs
- Neustart eines APs, wenn die Verbindungsprobleme um diesen AP sich häufen
- Änderung der Frequenz von 5Ghz auf 2,4 Ghz
- Aktivierung und Deaktivierung "Dyn Chan"
 
Alles leider ohne Erfolg.
 
Ich wundere mich besonders über die Meldung: "WPA IE from (Re)AssocReq did not match with msg 2/4", kann aber nicht zu 100% zuordnen, ob AP oder Client die Fehlerursache ist.
 
Ist jemandem dieses Problem bekannt?

    Hallo Stefan,

    das ist so korrekt.
    Möchtest du aber trotzdem den Sophos Support einschalten musst du das Ticket über deinen Sophos Partner/Reseller erstellen lassen.

    (Sorry, Stefan, but my German-speaking brain isn't creating thoughts at the moment. [:(])

    If you have a knowledgeable Sophos Solution Partner, you're better off paying them than paying for Premium Support.  All Premium buys you is the ability to open your own tickets.  I don't let any of my clients buy Premium, but I would recommend it to organizations that can't find a strong partner.  It takes time to learn how to work with support organizations and most IT folks already have too much on their plates.
