Please include if possible the firmware-b43-installer package on the next version of OSMC for ATV, current documentation on the web is a mess and doesn’t really help other than some almost decade-old articles on how to install deprecated blobs
Even if the Broadcom Crystal HD card is recommended I still think it’s of the user’s interest to have Wi-Fi working on a stock device
Users with an existing installation can install the proper non-free firmwares and modules to the system by running
apt-get install firmware-b43-installer
Then rebooting the system Wi-Fi should work, making sure that the b43 driver is then enabled
That’s a shame, I’ve just bought an ATV due to OSMC, but I’m really glad for all the support you have been giving, I’d like to help to keep supporting it if possible
