Can only connect on 2.5GHz But that's not a problem, now it keeps losing connection, after installation, less than half a year is connection lost and absolutely will not reconnect to wifi. The whole purpose of these lights is to connect with Alexa, and now they don't! Waste of money, don't buy it. It initially took hours to connect - when we changed our router's address we tried to connect again using the same steps for several hours and it didn't work! There are other brands with great reviews, I should have looked at the reviews for that - don't buy!
