Hello @Jpdcruz1992 

It is recommended to connect smart bulb directly  to Wi-Fi router first, not through extender, this helps to exclude the issue. 

If pairing failed or set up failed at step, you could also try some suggestions mentioned in thread

We have a  guide that might do some help, please give it a try:  

What should I do if I fail to configure the Tapo smart bulb?

Can you help confirm some case details here if the concern persists, thank you. 

• Model of router

Does smart device connect to router directly or through extender? 

• Model of phone and its Android or IOS version:
• A photo of router's wireless settings if possible
• A photo of error message on Tapo APP
