There is an amazing thread on this here - Installing Broadcom Wireless Drivers

Which sadly does not mention the 4464 adaptors. My machine (a 2018 Macbook Pro with an intel chip has the following)

Network controller [0280]: Broadcom Inc. and subsidiaries BCM4364 802.11ac Wireless Network Adapter [14e4:4464] (rev 03)
    Subsystem: Apple Inc. BCM4364 802.11ac Wireless Network Adapter [106b:07bf]
    Control: I/O- Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
    Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
    Interrupt: pin A routed to IRQ 255
    Region 0: Memory at 81400000 (64-bit, non-prefetchable) [disabled] [size=32K]
    Region 2: Memory at 81000000 (64-bit, non-prefetchable) [disabled] [size=4M]
    Capabilities: <access denied>
    Kernel modules: brcmfmac

The adaptor is not listed in the various responses, and I have tried all the options to no avail - still no wifi!

Output of sudo dmesg | grep brcm gives :

Does anyone have an idea how to make this work with the 14e4:4464 version?

Thank you so much!

If you do not have a mac anymore, because you are like me and accidentally overwrote the disc with mac on it, here is a repo with the bscmwl files: https://github.com/AdityaGarg8/Apple-Firmware

On a PC with internet

$ curl -s --compressed "https://adityagarg8.github.io/t2-ubuntu-repo/KEY.gpg" | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/t2-ubuntu-repo.gpg >/dev/null
echo "deb [signed-by=/etc/apt/trusted.gpg.d/t2-ubuntu-repo.gpg] https://github.com/AdityaGarg8/Apple-Firmware/releases/download/debian ./" | sudo tee -a /etc/apt/sources.list.d/t2.list
sudo apt update

$ apt-get download apple-firmware

Transfer the Package to a USB Drive and copy them to the T2-linux-mac

$ sudo dpkg -i apple-firmware*.deb

I got the wifi working
