Hallo, ich habe das Problem, dass oft das WLAN nicht funktioniert, obwohl mir der Netzwerkmanager das WLAN-Netz anzeigt. Wenn man versucht sich mit dem Netz zu verbinden, scheitert der Verbindungsversuch in der Regel. Manchmal kommt es vor, dass es dann doch klappt, dann ist aber die die Übertragungsrate so gering, dass man keine Internetseite aufrufen kann. In seltensten Fällen, klappt die WLAN-Verbindung dann korrekt, so wie gerade jetzt. Sonst hat das WLAN immer korrekt funktioniert. Ich weiß leider nicht genau, seit wann das Problem auftritt, da das nicht mein Laptop ist.
Die Linux-Wireless-Backport-Module sind installiert. Das Problem existiert jedoch weiterhin.

Ich habe den Lucid Mainline Kernel v2.6.34 installiert. Das Problem existiert jedoch weiterhin.

Ich wäre für jeden Tip sehr dankbar.
BTW: Ich habe noch einen Laptop (Kernelmodul: ath5k) und einen Desktop (Kernelmodul: rt61pci) bei denen ähnliche Probleme auftreten und sie sind alle im selben WLAN-Netz. Mit meinem Smartphone funktioniert es aber problemlos sich mit dem WLAN zu verbinden. Weiterhin treten auch ähnliche Problem bei dem Desktop-Rechner (Kernelmodul: rtl8185) eines Freundes auf. Alle diese Rechner haben unterschiedliche WLAN-Karten verbaut und alle funktionierten vorher problemlos. Teilweise durchziehen sich diese Probleme durch mehrere Ubuntu-Versionen.
