Hallo,
ich habe ein neues Dell Notebook Studio 15 und es mit Ubuntu 10.04 bestückt. Das lief super einfach und alles wesentliche hat auf Anhieb funktioniert inklusive WLAN (Intel).
Im Betrieb hat sich ein sehr nerviges Problem herausgestellt, dass ich bis hierher nicht selber lösen kann. Vielleicht hat jemand eine Idee...
Auf der Tastatur gibt es eine Taste zum De-/Aktivieren des WLANs (F2, Antennensymbol). Wenn ich diese Taste drücke (und das passiert leider auch mal aus Versehen, weil sie so einfach erreichbar ist) wir das komplette WLAN deaktiviert. Ein erneutes Drücken der Taste reaktiviert es aber nicht. Bisher ist es mit nur durch zufällige, nicht nachvollziehbare Tastenkombinationen gelungen das Funknetzwerk wieder zu aktivieren. Manchmal ging es auch über Tage hinweg nicht, mehrere Reboots dazwischen.
Das Ganze hat meiner Ansicht nach nichts mit der softwareseitigen Netzwerkkonfiguration zu tun sondern nur mit dem schlichten Ausschalten der Hardware. Wäre ja auch nicht so schlimm, wenn ich es einfach wieder einschalten könnte.
Unten die üblichen gewünschten Angaben zu Kernel und Config, aber wie gesagt ist hier der Grund wahrscheinlich nicht zu suchen....
Ideen?
Danke und Gruß, bhr
