Salve a tutti.
Da alcuni giorni, l'accesso ad Internet via WiFi con OpenSUSE 13.1 KDE 64 bit è discontinuo; capita così che, nel bel mezzo della navigazione, non sia possibile caricare altre pagine WEB, nè ricaricare quelle già caricate.
Quando ciò accade, l'interfaccia grafica per gestire la rete indica che sono connesso ad Internet e che non vi è scambio di dati, nè in ingresso, nè in uscita.
Mi è accaduto anche pochi minuti fa.
dmesg fornisce questo output:
