Da sich ein Linksys E900 Router von Ubuntu 12.04 nicht verbinden lässt, verbindet sich derselbe Laptop (Dual Boot) von Windows 7, derselbe Laptop, ein anderes Haus. Ubuntu verbindet sich. erster Router Linksys E900 Firmware 10.0.03, zweiter Router Linksys E1500 Firmware 10.0.0. Bei der WLAN-Karte handelt es sich um eine Broadcom, und der Treiber ist installiert. Ich denke, es gibt etwas in der Firmware-Aktualisierung, die in der Software des Netzwerkmanagers behoben werden muss. Die Sicherheit beider Router ist WPA2 Personal. Bitte helfen Sie.
