Spotify is dropping my internet conextion in all of my devices

[user-removed]

Everytime when i open my spotify using my wi-fi my conection is lost in all of the devices that are using my wi-fi. Like if there is a online tv show runningand somebody is using a computer as well and if i open my spotify it will drop the conection in all of the devices. It has been happining over 3 month. I though it was a sotware problem so i was waiting for updates but it never seem to get better. Please if it has happened to you help me to fix this problem.
Thank you
