Bis zu den Pings bestand eine Verbindung via LAN-Kabel. An dieser Stelle habe ich natürlich das LAN-Kabel entfernt, sonst hätte der Test ja nichts gebracht. Davor war eine Verbindung irrelevant, oder? Falls nicht, sagt das bitte, dann gebe ich alle Befehle erneut ein.
freundliche Grüße
Edit: Es tut mir Leid. Ich weiß jetzt, warum die LED andauernd so blinkt. Meine Schwester hängt die ganze Zeit in dem WLAN-Netz drin und weigert sich, das kurz mal aus zu stellen. Meine Eltern weigern sich beide, sie kurz davon zu überzeugen. Ich werde euch die Information so früh wie möglich zukommen lassen.
Edit2: So, sie hat ihren Laptop jetzt ausgeschaltet. Die W-LAN-LED am Router blinkt in langen Abständen ohne klare Regelmäßigkeit, egal ob mein W-LAN-Stick im USB-Port steckt, oder nicht. Die LED brennt die meiste Zeit, im Abstand von (immer anders) 1-5 Sekunden geht sich ganz kurz aus. Ob der Stick steckt, oder nicht macht keinen Unterschied.
Edit3: Wenn ich den W-LAN-Stick unter Windows XP (da funktioniert er, selber Rechner, selber USB-Port) verbinden lasse, blinkt die LED wie wild. Auch die LED am Stick selbst blinkt. Die LED am Router blinkt immer mindestens 2-3 mal in Folge, nicht einzeln, wie unter Linux oder ganz ohne angeschlossenen Stick. Der Stick hat unter Linux also absolut keine Verbidung zum Router.
