...........Allora, nel dettaglio adesso ti spiego cosa succede:
collego il tablet via usb, attivo il teathering, attivo il wifi:

.....Quindi c'è un errore sul modulo rndis_host.............come lo risolvo? Secondo me ci manca qualche pacchetto ad hoc che tu hai installato e lo dai per scontato.............Considera che la distro Ubuntu16_04 installata è quella vergine, pulita presa pari pari da distrowatch.......
Mi manca poco

Sì, c'è un errore nel modulo rndis_host.

E' possibile che non carica il modulo option.

Rifai la procedura, da terminale postami questo comando:

Prova a dare questi comandi senza collegare il tablet:

Codice: Seleziona tutto

sudo modprobe -v option

Codice: Seleziona tutto

sudo modprobe -v  rndis_host

inserisci il cavo usb del tablet nella porta usb ed attiva il tethering usb, da terminale postami questo comando:

Codice: Seleziona tutto

dmesg | grep usb

[zaghenh20]

.........Scusate per l'attesa...

poi attivo il teathering usb secondo le modalità in precedenza indicate e do questo comando:

....Risco collegarlo via cavo. Eseguo l'update e l'upgrade poi invio tutti i comandi descritti nella guida di ubuntu peronista. Riavvio senza cavo inserito e magicamente ed incredibilmente si connette (con il networkmanager):sofico:
Il giorno dopo avvio ubuntu e purtroppo sono punto e accapo......... non si riesce a connettere.......proprio non riesco più a capire.......eppure il led adesso lampeggia come se si stesse per connettere...., ho controllato il modulo con il comando:

Ho ripetuto l'avvio della rete con i comandi manuali........
Ho provato ad avviare anche il kernel precedente........
Ho stoppato il demone avahi......

Niente di niente.. Prima di ritornare dall'amico.....vorrei quanto meno capire qual'è il problema e dove posso aver sbagliato..
