Hallo,
ich habe über ein Netzwerkkabel eine xbox an meinem PC angeschlossen, um
dann über wlan ins Internet zu kommen. Seit dem Upgrade auf wheezy kommt
es nun beim online spielen aber immer wieder zu Verzögerungen (Lags), die
das Spielen fast unmöglich machen.
Ich habe probehalber mal einen wlan USB-Stick angeschlossen, der das
carl9170 Modul benutzt und hatte damit keine Probleme.
In den Logs und in der Ausgabe von dmesg finde ich keinerlei
Anhaltspunkte für das Problem und auch bei der "normalen" Nutzung gibt
es keine Auffälligkeiten. Nur der ping Befehl zeigt regelmässige
Verzögerungen, die auf das Problem schliessen könnten.
