By doing so, the Wi-Fi network management solutions described herein allow the users to experience the benefits of a shared Wi-Fi infrastructure, such as not having to set up and maintain their own Wi-Fi routers, while also allowing them to easily change their Wi-Fi settings from their connected devices. ## Claims ### Claim 1 A system comprising: a storage device configured to store user data associated with a plurality of user accounts for a wireless network;
