habe einen L-322agn Dual im Einsatz (Signatur ist nicht mehr aktuell). Parallel 2,4 und 5 GHz mit identischer SSID, Verschlüsselung und Band Steering aktiv. Der AP dient ebenfalls als DHCP-Server.
Mit meinem Android Handy (Nexus 4) habe ich Probleme mit der WLAN-Verbindung. Obwohl es anzeigt, dass es mit dem WLAN verbunden ist, kommt keine Datenübertragung zustande.
Anbei mal ein Auszug aus dem syslog des Lancom zu einem Zeitpunkt, wo das Phänomen aufgetreten ist (Mac ist die ...23:56):

Ab hier passieren viele für micht nicht erklärbare Dinge:
Zeile 2017: WLAN error: too many beacon transmit failures
Zeile 2020: last message repeated 3 times
häufige Zuordnung der IP an denselben Client innerhalb kurzer Zeit (vgl. Zeile 2009, 2028, 2037, 2046) während gleichzeitig das Frequenzband (von 2,4 auf 5 GHz und umgekehrt) gewechselt wird.
Zeigen diese syslog-Ausgaben ein normales (nachvollziehbares) Verhalten, oder läuft da irgendwas falsch?
Danke
