I’ve bought new Yeelight Bedside Lamp 2. I’ve downloaded the latest version of the Yeelight app from Play Market.
Try to connect the lamp to my phone (Galaxy s7), or tablet (Galaxy Note 10.1 2014Ed) through the app.
Situation is the same: the MAC address of the lamp is detected. But then the attempt to connect fails after waiting for a long time. The massage follows: couln’t connect to device hotspot… Something about network…
I did it several times, connected to different servers: Germany, Russia.
I asked my admin to include the MAC-address to the list of allowed addresses.
My wi-fi at home works properly, internet is ok, local windows network is ok.
Is it a problem with the firmware, or my local network?
Could you have a try with changing your router’s DNS server to 220.127.116.11 instead of using automatically allocation?
Also, try to disable 5 GHz WiFi interface and use just 2.4 GHz. For me it doesn’t connect when both are active (in the Band Steering mode).
