Hallo,
an diesem Laptop, einem Thinkpad T500 mit Intel Ulitmate N Wi-Fi Link 5300, funktioniert das WLAN nicht.
LAN ist kein Problem.
M.E.n. ist vor dem Release von 16.04 das WLAN noch betriebsam gewesen, nach einem darauf folgenden Update dann nicht mehr. Router ist eine AVM Fritzbox 7390, deren Einstellungen unverändert sind. Mit einem anderen Gerät besteht auch WLAN-Verbindung.
