    Abstract: This document discloses a solution for controlling connectivity of a dormant station. According to an aspect, a method comprises: entering, by a station of a wireless network, a dormant mode in which a main radio interface of the station is disabled and a wake-up radio interface of the station is enabled; scanning, by the station, for a beacon signal by using the wake-up radio interface in the dormant mode and determining, as a result of said scanning that no beacon signal is detected; as a response to said determining, switching by the station from the dormant mode, enabling the main radio interface, and transmitting to a wireless device a frame comprising an information element indicating incapability of detecting said beacon signal; and receiving, by the station from the wireless device, a frame indicating improved conditions for detecting a further beacon signal and, upon reception of the message, returning by the station to the dormant mode.
