PS : When you type in this “http://fritz.box/html/support.html” the page you will see might be different according to your Firmware version, but should be OK to find your mac addresses. My FRITZ!Box is the 7390 International version. “fritz.box”” can be replaced by your Fritz!Box IP address, usualy 192.168.178.1)
