-There might be cases where you don't want to affect the full radio chipset but rather restrict access to a specific SSID. This is achieved as follow:
-- Identify the SSID virtual interface you want to affect. Remember virtual interfaces are always defined as [ main wireless interface name ] + [.] + [a number 0-3] so e.g. "wl0.1". The full list of wireless interfaces available on your router and the all their sub-interfaces once again can be found under [[advanced-wlanvifs|Virtual Wireless]] e.g.\\
