After spending several hours trying to connect these lamps to Wi-Fi and Alexa, I called Sengled Technical Support. They asked me a series of questions about my problem and my wireless router. When he heard that I have a Wi-Fi 6 mesh router, he said that their Wi-Fi bulbs weren't working well with Wi-Fi 6 and that I should switch to the Bluetooth version of their bulbs. (He also said that other manufacturers' WiFi bulbs have the same problem.) So I'm sending them back and ordering the Bluetooth version, which is cheaper anyway. I wish the Revain reviews would mention this issue so folks on Wi-Fi 6 don't waste their time the way I do. Another problem is that Revain did not automatically register these lamps in my account when I bought them. You should do this as Alexa can easily connect these lights without having to use the Sengled app.
