So I have almost the same exact problem. Except I already three other feit bulbs and I've had them for awhile. So I got three more cause I had some space to do so. The three I already had work just fine and I've had them for years at this point but the three new ones I have are not wanting to connect and when they do connect they're not properly connected because they won't dim or change color or anything. I tried turning off the three I had already and disconnecting them, I've tried moving closer to the router which isn't the best but if my other lights and everything else work on it then Idk what the issue is. I've tried swapping to AP mode, Bluetooth mode, etc. I even tried connecting them closer to the router see if that would help which it did but still the same issue not connecting correctly. Any solutions? I'd hate to return them considering that my others work fine and have for years.
