[RISOLTO] MATE 20.04 utilizzare adattatore wifi usb su iMac

[robbatista]

Salve,
ho installato Mate su un iMac del 2008. Ho notato che il computer ogni tanto si disconnette dal router (questo lo faceva anche con Osx quindi suppongo sia un problema hardware).
Possiedo una chiavetta usb tp link e vorrei utilizzare quella per far collegare il mac alla rete. Vorrei quindi sapere come fare per disabilitare il modulo interno del Mac.
Mille grazie

Dovrebbe essere sufficiente individuare quale modulo del kernel viene impiegato e metterlo in blacklist. Con l'adattatore USB scollegato, esegui lspci -k e posta l'output.

Grazie per l'interessamento intanto.
Ecco l'output:

Credo sia questo, in tal caso puoi disattivarlo creando il file /etc/modprobe.d/blacklist.conf col seguente contenuto: blacklist wl. Salva e riavvia.

[robbatista]

Ho fatto come da te indicato ed effettivamente al riavvio non c'era alcuna wifi disponibile. Ho pluggato il modulo esterno e mi sono connesso.
Grazie, vediamo se ci saranno ancora disconnessioni dopo un po' di uso.
