2 Bulbs fail to connect tried almost everything

Hope this is the right place. I have 2 WYZE bulb that keep failing to connect.
2.4 gHz
Switch wifi-s to bulb
reset router
Lamp dircet pug to wall
Bulb in lamp 3 feet from router
Reloaded app

2 bulbs work fine. Wonder what I might be missing? Othe bulbs work fine in the lamp. I use it as a lamp to set up bulbs then take them where they are to be used. ANY clue would be helpfull!! MAYBE I have too many devices on network?

Turning off Mobile Data was my resolution for bulb connection issues, after making sure the phone was on the 2.4 ghz WiFi channel.

Perfect!!! Thank you!!!
