1. Config main router (in my case a Zyxel) in Network/Wan/Internet Connection in mode ‘routing’. In most cases is the default mode, and you don’ t need to change anything.
2. Change N1 Vision’s IP to the same range of the main router (the router connected to the ADSL connection). Example: my router Zyxel’s IP is 192.168.1.1: change N1 Vision IP to 192.168.1.2.
3. Disable DHCP server in N1 Vision.
4. Connect by ethernet the main router with the belkin n1. The belkin n1 is working as access point.
