  • Wifi not detected on 2012 IMac in 11.0

    Hello,

    Please can I have some help.

    I have several Intel IMac's running 10.0.4, these work great. I upgraded one to 11.0.0 today however the wifi card is not detected.

    In a working 10.0.4 setup I see this in dmesg:

    [ 3.617493] Bluetooth: hci0: BCM20702B0 Generic USB Class 1 @ 20 MHz

    [ 3.623046] wlan0: Broadcom BCM4331 802.11 Hybrid Wireless Controller 6.30.223.271 (r587334)

    I presume this driver is no longer present in 11.0.0.

    Pastekodi from both versions here -

    I could do with a hint on how to resolve this. Thanks in advance.
