Many customers have difficulty setting up a new extender device in the customer premises environment to improve their multimedia service. Some embodiments include configuring an extender device based on existing WiFi network credentials to minimize errors. Some embodiments include an application for mobile devices that may enable the transfer of network credentials from existing multimedia devices on the WiFi network to configure a new extender device in real time. For example, the configuration may be based on a customer account, a corresponding environment, and corresponding multimedia devices associated with the customer account. The extender device may be configured with the network credentials (e.g., a WiFi service set identifier (SSID) and password) that is common to the corresponding multimedia devices associated with the customer account.
