## Abstract

An apparatus, system, method, and computer-readable recording medium monitor and detect connection issues in a wireless network. The wireless network communicatively interconnects a gateway device including a network controller, wireless extenders, and client devices. The gateway device receives probe requests from the client devices and the wireless extenders, and the network controller periodically monitors at least one of: i) frame parameters or ii) signal strength information based on the probe requests, and identifies a connection issue with respect to at least one of the wireless extenders. The gateway device transmits a report or alert regarding the connection issue to at least one client device, and the report or alert is used to prompt re-installation of the wireless extender having the connection issue.
