WiFi repeater setting issues
That explains the connection between your repeater and the wireless router. Reconfigure the repeater and router's wireless bridging.
Your computer or cell phone is connected to the router via a repeater and gets the IP parameter, so it's slower than normal, but usually not more than 2 minutes.
You should enter the MAC address of each other on the router and repeater, so that the wireless relay can be carried out effectively.
