Xiaomi Desk Lamp can't connect to Wi-Fi

I’ve connected my other Xiaomi lamp (the Mi Bedside Lamp) using the official Android Yeelight application with absolutely no problems, but I can’t connect the Desk Lamp no matter what I’ve tried.

The process that I follow:

  1. Make sure that the lamp is connected to the power adapter (it turns on)
  2. Make sure that the device is added to the white list on my router
  3. Turn on the Yeelight application, select the Desk Lamp from the Add new device menu
  4. Click next, reset the device using the reset button on the bottom of the base of the lamp (the lamp blinked 5 times to confirm that it did successfully reset) as shown on the screen
  5. Click next, the app is searching for the device - it found the MAC address of the device so I choose it and click next again
  6. The app is searching for my Wi-Fi network, I type in the password and click next

Now the app is stuck on the “Updating connection status, just a sec…” indefinitely, it goes to 100%, connection times out and it asks me to try again.

What I’ve tried so far:

  1. Changing the network mode between:
  • 2.4GHz + 5GHz
  • 2.4GHz only
  • 5 GHz only
  1. Changing the security mode between:
  • no security
  • WPA-PSK/WPA2-PSK
  • WPA2-PSK
  1. Changing the network standard between:
  • 802.11 n
  • 802.11 g/n
  • 802.11 b/g/n
  1. Changing the channel width
  • 20 MHz
  • 20/40 MHz
  1. Changing the name of the network
  • only lowercase letters
  • only uppercase letters

I’ve returned the lamp to the seller and got a new one of the same model - the problem is still occurring.

I’ve also tried using a different application (Smart Home), deleting the other lamp from the app and router before connecting this one, using WPS, using a different phone (Samsung Galaxy S8, Samsung Galaxy S Plus, Sony Xperia Z3C) but nothing helped me so far.

I’ve seen on the forum that some people are asked for their Mi ID, so here it is: 1797738056
