Question about Swisscom WLAN Box 2

No, you cannot connect a WLAN Box 2 directly to an existing WLAN Box 2 to extend the network. The WLAN Box 2 only connects wirelessly or by cable to the Swisscom Internet Box and extends its WLAN signal as a repeater or access point. Up to 4 WLAN Boxes can be used simultaneously with the Internet Box; they communicate with each other via mesh technology, but not directly with each other as a master-slave.
