Request WiFi repeater settings, I do not know the other router's model and password, but I know the WiFi password!
Close your router DHCP service and note that the two routers cannot be the same gateway. Commercial router settings method: your router MAC address, such as the other router, and then the other router MAC address, such as your router. Close dhcp. Gateways can not be the same. Restart your router after you have finished setting up
Settings: General router. First open your router's WDS function, scan SSID, select the WiFi signal you want. Input password。
The first step is to find the brand model of the other router. The second step is to buy a router that is compatible with each other's router, and basically compatible with the same brand. The third part is setting up.
