Hello   @RickyReyesmatri 

May I know how did you tell smart bulb to lose wifi connection?  If bulb loses Wi-Fi it will disappear from router's client list and should be unreachable in Kasa APP .

• Please confirm smart bulb has a strong wifi signal in case1
• Check if there is any Advanced WiFi settings on main Router, if so, temporarily turn it off :  Band Steering（Smart Connect）/ Channel optimization（Wi-Fi Optimizing) etc

When issue occur, can you help provide some details here to help exclude the issue, thank you

• Can you control the device locally (same network) from the Kasa app? 
• Can you control the device remotely (LTE or different network) from the Kasa App?  
• Any error message you receive from Alexa app, please share a photo
• What Alexa did say to a voice command and the more exact time :   e.g. 9:00AM,  ' Alexa, turn Alexa Family Room on' , Alexa responds ' ...

Does other network device connected to router work stably at that time, what is the model of router, do you have camera connect to router directly or through extender, what is the Alexa APP version? Please share the MAC address of bulb with us via private message,   Thank you
