[Risolto][per modo di dire]Bluetooth Broadcom problemi streaming audio

Buonasera a tutti

sto riscontrando dei problemi con un bluetooth BCM20702A1 integrato in una wifi intel centrino . Per qualche secondo il bluetooth sembra funzionare dopo di che l’audio si blocca e tanti saluti alla cassa bluetooth.

non so come venirne a capo

Ho risolto sostituendo il modulo wifi (centrino N6205) con una versione supportata da Linux (centrino N 1030). Non c’è stata soluzione , le ho provate tutte
