Administrators Hervé Posted February 19, 2018 Administrators Share Posted February 19, 2018 This old card is not supported beyond ML. All other BCM431x cards were last supported in El Capitan 10.11 and dropped from Sierra 10.12. You'll have to replace your ancient DW1397 with something supported and, ideally, more recent. See our wireless cards inventory published in this very section. You can also revert to your vanilla IO80211Family kext. Link to comment Share on other sites More sharing options...
