I have 3 Basic Wifi switches which were in a working condition. When I changed the router and modem and tried to pair them again I was no longer able to pair them.
Only 1 of 3 switches connects successfully. As for others they aren't detected in the full 3-minute long search cycle. Even if the AP mode detects these switches, they never pair with the internet router.
I see many people have a similar problem and the general consensus seems to be that the problem is the switch reporting itself as localhost to the router and most (except the Xiaomi repeater) routers do not like that.
Is there a solution? I cannot recommend this product to others if this issue is still unresolved after 3-4 years.
