hi my friend, many thanks for the video. However i belive the latest updates broke what's briently explained in the video. For example, for routers with the wifi tab active, security profile not longer have the radius tab, to do mac authentication. For routers with wireless tab you still radius in security profile but i'm no longer able to put mac authentication to work post Routeros 7.15 update. It would be great if you could record an update video covering both cases. Many thanks for your work.
