with the DUO connection kit you will extend your LAN to another room. one UNO to the ADSL router and the second in the other room. on the second you can connect Swisscom TV, PC's via cable or a WLAN Basisstation ("Apple Airport Extreme" in my case)
I installed the WLAN connection kit for second Swisscom TV. Alternative would be a Powerline.
Without Swisscom TV an extension of your existing WLAN is also possible without this connection kit, but the Swisscom TV box has to be connected directly to the Swisscom router or via a Powerline or to a Swisscom UNO via the WLAN connection kit.
But I doubt that a NetGear WPS device can be added to the Wireless network created by the connection kit with uses MESH technology.
