I have a Fritz!Box 6490 (cable), which comes with an dualband Wifi, meaning 2,4GHz and 5 GHz.
So, If I add this item:
Switch Fritz_GuestWifi "Guest WLAN" (gFritz) {fritzboxtr064="wifiGuestSwitch"}
That switch will toggle the 5GHz Wifi, though in dualband Wifi Router (as mine)
I think, that has something to do with the internal numbering of the fritzbox:
2,4GHz
------

URI: urn:dslforum-org:service:WLANConfiguration:1
second Wifi/Guest or 5GHz
-------------------------
Location: http://fritz.box:49000/upnp/control/wlanconfig2
URI: urn:dslforum-org:service:WLANConfiguration:2
Guest (if dualband Wifi)
------------------------
Location: http://fritz.box:49000/upnp/control/wlanconfig3
URI: urn:dslforum-org:service:WLANConfiguration:3
is there a way to reach Guest-Wifi with the current binding? or is there an patch within the binding necessary?
