How to make the “LAN” and “WLAN” interfaces in the wi-fi router work on the same ip-address?

Question

WiFi

Huawei router, I don’t remember the model, but the box was lost. It is necessary, I repeat, to make sure that, in the end, the "LAN" and "WLAN" interfaces work on the same ip-address. Well, or more simply, you need wi-fi to have the same ip as the LAN connection passing through the router.

Answer 1

Make a bridge from these two interfaces and assign the desired IP to the bridge (by the way, this is done by default in the vast majority of routers)
