Question about Strong Powerline Wi-Fi 500 Kit PowerLine Router (POWERLINE WIFI 500 DUO)

I wanted to try out the router function. Since then I can no longer connect to the admin interface (neither via LAN connection with the device nor via WLAN). The strong.tv FAQ claims that the IP can be found under the "connected to your box" entries. However, no new device is displayed when I connect it or not. Passing on LAN/WiFi works anyway. I cannot connect to the user interface via the URL: http://strong.500.ap or the IP address: 192.168.1.254 Your Wi-Fi Powerline has probably obtained another IP address from your Internet box (router). Connect to the management interface of your Internet box and check the IP address assigned to your powerline (there should be a "device management" menu with the list of IP addresses assigned to all devices connected to your box). Then enter this IP address in the address bar of your Internet browser.
