Cant connect

yeelight (white) now only works manually !!. ie swith on or off using the wall swithc like a regular light.
Cannot control it using the wifi. It used to fork fine till afew days ago !!
Whats happening ?/

  1. Check if the bulb is still connecting to your router.
  2. In App, Logout and login again to see if it works.

How do i ensure its still connected to the router. ?
I have already logged in and out many times.

Logon to your router’s management portal, check the DHCP client list and then ping “the ip of your bulb”.

How do I do all of that you mentioned.
By the way if its not in the list can i assme that the bulb is faulty ?
