Hallo Zusammen!

Ich habe grade ein seltsames Phänomen meiner WLAN Karte entdeckt!

Das WLAN funktioniert einwandfrei, solange ich mein Laptop am Netz habe! Sobald ich den Strom ziehe, verliert er die Verbindung und fragt mich nach ein paar Minuten nach dem Schlüssel des WLANs. es funktioniert dann aber auch nicht mehr, wenn ich den Laptop wieder mit Strom versorge. Es hilft nur ein Reboot mit Netzteil. Dann geht es wieder ohne Probleme.

Was braucht ihr von mir für Angaben?

EDIT

Es dauert nicht immer gleich lange, bis die WLAN Verbindung abbricht. Allerhöchstens 2 Minuten, nachdem der Netzstecker gezogen wurden.

Hallo,
siehe http://forum.ubuntuusers.de/topic/wlan-verbindung-im-akkubetrieb/

War schon dabei alles einzutragen! Ich hoffe, dass da irgendwas dabei, was mir bei dem Thema helfen kann!

Frage den Zustand mit

iwconfig wlan0

ab.

Die PM-Einstellung ist in beiden Fällen zumindest in Ordnung. Du könntest es mit dem Broadcom STA-Treiber versuchen. Schau mal ob dieser im restricted-manager angeboten wird.

Ansonsten ein fach ein

sudo apt-get install bcmwl-kernel-source

und noch die Sperrliste manuell ändern

sudo gedit /etc/modprobe.d/blacklist-bcm43.conf

Inhalt ggf. so ändern sofern nicht schon automatisch geschehen:

blacklist b43
blacklist b43legacy
blacklist ssb
blacklist bcm43xx

Neu starten und die Installation überprüfen.

lspci -nnk | grep Broadcom
iwconfig
dmesg | egrep 'b43|wl'

Sofern alles funktioniert die Verbindung im Akkubetrieb testen.

Sofern der neue Treiber nicht funktioniert die /etc/modprobe.d/blacklist-bcm43.conf anpassen und neu starten:

blacklist wl
# blacklist b43
blacklist b43legacy
# blacklist ssb
blacklist bcm43xx

Die PM-Einstellung ist in beiden Fällen zumindest in Ordnung. Du könntest es mit dem Broadcom STA-Treiber versuchen. Schau mal ob dieser im restricted-manager angeboten wird.

Ansonsten ein fach ein

sudo apt-get install bcmwl-kernel-source

Der STA Treiber wird zwar angezeigt, aber wird über den restricted Manager nicht installiert. Da kommt eine Fehlermeldung! Wenn du mir sagst, wie ich die vernünftig auslesen kann. Poste ich sie dir!

Sudo apt-get install bcmwl-kernel-source wird auch nicht installiert, da er das Paket nicht findet!

hoffe, dass du mir noch weiter helfen kannst! Danke schonmal für deine Hilfe!!

Du benötigst zu den angegebenen Befehlen eine bestehende iNet-Verbindung.

sudo modprobe -rfv b43
sudo modprobe wl 

iwconfig
ifconfig -a
dmesg | egrep 'wl|eth|lib'
iwlist chan
sudo iwlist scan

Ich weiß nicht warum, aber jetzt hat er das Paket gefunden. Es scheint auch zu funktionieren. Hab es vielleicht falsch geschrieben oder ich hatte wirklich keine Internetverbindung.

Könntest du mir noch sagen, woran es jetzt genau gelegen hat? hab alles gemacht was du mir gesagt hast, aber ich würde auch genau verstehen, was ich da überhaupt gemacht habe

Und wieso heißt Wlan0 jetzt auf einmal eth1?

Danke für deine Hilfe!

Für Broadcom-Karten gibt es zwei Treiber die mit bestimmten Karten funktionieren, den freien Treiber b43 und den proprietären Station-Treiber von Broadcom. Für die hier verwendete Karte (Broadcom Corporation BCM4312 802.11b/g LP-PHY 14e4:4315) sollte besser der STA-Treiber verwendet werden. Ob das reibungslos funktioniert muss man ausprobieren, da es zwei Varianten dieses Typs gibt.

Wir haben jetzt also nur manuell b43 deaktiviert und STA (Modul wl) installiert. Nichts anderes macht der restricted-manager über Skripte. Allerdings ist ja noch nicht klar ob der eigentliche Fehler damit behoben ist.

Ich habe grade mit Akku gestartet und die Verbindung scheint nicht abzubrechen! Es scheint, dass es funktioniert!

ich danke dir sehr für deine Hilfe!!!

Teste das in Ruhe aus und markiere hier als "gelöst" wenn die Verbindung stabil läuft.
