If anyone could help with configuration to extend my primary airtel router to both TP-Link and Jio fiber router. I have connected the airtel router to other two routers using Lan cables. By default, the range extends but the other two routers have issues with assigning IP addresses. For example, if a device is connected to tplink router on 5G band. I cannot connect another device to the 5G band access point. It's the same 2.4G band, If a device is connected to it, any other device can't be connected.
