Cannot Install Yellight Bulb (Color)

So, I’ve recently purchased the Yeelight bulb v2 (white bottom) and I’m having all kinds of issues on getting it to set-up.

Most noticeable is that after selecting the bulb, typing the password, and clicking connect, the phone will connect to the wifi network of the bulb and instantly disconnect, which makes a failed installation (timed out).

This seems to happen with all phones I have at hand, and is starting to sound like a firmware issue or bad wifi network emitted by the bulb.

Does anyone have any clue on how to fix this issue? These weren’t cheap!


For the connection issue, you can check by the following steps to see where the problem is:

1)Reset the lamp by power on and off fives times in a row, and then see if there’s AP named like “yeelink-light-***” in your phone’s wifi list? If yes, go to see Step 2; If no, it means there’s something wrong with the wifi module of your lamp;

2)In Yeelight/MiHome application, add the lamp you want to connect. Make sure there’s no special character of your router’s password. If the connection successes, congratulations, if not, go to Step 3;

3)See if the lamp in your router’s DHCP list, if yes, it means there’s something wrong with connection between your router and Mi cloud. Please have a check with your ISP if it blocks some domain of xiaomi. If there’s not the lamp in your router’s DHCP list, it means, the lamp has problems to connect to your router. So please have a check if your router block the lamp or your router has connected as more devices as it can connect.

So please have a check that which step do you stuck?

You have a try with:

  1. Use another phone to setup a hotspots with 4G network and try connect the bulb to it.
  2. Try with changing your router’s DNS server to instead of using automatically allocation.


Hey, thanks for the help, managed to get it working after like 10 consecutive attempts (Really hard to get the wifi of the bulb to not disconnect me).

One extra thing, the MiHome app doesn’t have these new bulbs on the US server :smiley:

No, not all products support mihome US server. Yeelight app will work.
