    only if connected in a not obvious manner
    no, that will not work as it is only a 'wire connector' and not a signal converter.

    here's how; do not put anything into the RJ11 slot on the ADSL WiFi router.

    connect an ethernet cable from a LAN slot on the router connected to the phone line
    TO another lan slot on the WiFi router. This will cause the WiFi router to act very much
    link a switch. Just be sure the DHCP service (on this device) is disabled and only the primary router has DHCP active.

    You will still need to setup the WiFi configuration (but do so ONLY with a wired connection to it).
