Hallo Community,
ich habe das Problem das auf meinem neuen Lenovo Ideapad Z710 unter Ubuntu 14.04 das WLAN nicht funktioniert. Im Menü Network Connections ist Standardmäßig nur die Ethernet Verbindung vorhanden. Ich habe manuell die WiFi Verbindung hinzugefügt, jedoch tut sich nichts.
Auf einer weiteren Partition habe ich WIndows 8 laufen, da läuft das WLAN ohne Probleme.
Bin jetzt etwas mit meinem Latein am Ende.
So dann werde ich jetzt mal den weiteren Fragenkatalog abarbeiten:
Wie ist das Netzwerk aufgebaut?
Es handelt sich um ein ganz normales Heimnetzwerk. Das Notebook, einen Router und eine 6000er DSL Leitung.
Welche Geräte werden verwendet? Lenovo Ideapad Z710, Speedport 501V
Welcher Internetanbieter? Telekom
Ist der Chipsatz der Netzwerk-Hardware bekannt? Nein Wird das Netzwerkgerät von anderen Geräten erkannt? Switches, Router und einige DSL-Modems signalisieren mit einer LED, ob am anderen Ende eine Verbindung besteht. Wie gesagt unter Windows funkioniert es deswegen gehe ich davon aus das das Problem nicht beim Router zu suchen ist.
Jetzt zu den einzelnen Befehlen:
