Hallo allerseits, seit etwa 2 Wochen nutze ich Kubuntu 12.10 und bin soweit auch damit zufrieden, bis auf ein Problem mit dem WLAN. Internetseiten bauen sich teilweise sehr langsam auf und die Verbindungsrate schwankt bei Downloads sehr stark, bis die Downloads abbrechen. Mit 2 Win7 PCs im selben Raum besteht das Problem nicht, da habe ich hervorragende WLAN-Verbindungen.

Hier die Infos:

Sollte noch etwas benötigt werden, reiche ich es gerne nach.

Hey, hab gerade die Anleitung befolgt, aber nach der Aktion ist es eher schlechter als besser geworden. Kann mich auch erinnern, dass das Problem erst nach einer Aktualisierung auftrat. Direkt nach der 12.10 Installation konnte ich noch mit Voll-Speed downloaden.

Vielen Dank erstmal für deine Mühe.

Hier ist die Ausgabe:

dmesg | egrep 'rt2800pci|rt3390sta'
[ 18.007073] Registered led device: rt2800pci-phy0::radio

Grüße

Schaut so aus, als lief's jetzt. Vielen Dank!

Schönes Wochende noch!

Hey, welche Einstellungen meinst du denn?
Seit der obigen Aktion habe ich jedenfalls eine stabile Verbindung. Danke nochmal an bsn.
